modeling environment.
2. Orbit
By pressing the shift key on your keyboard while holding down the middle
mouse button you are able to orbit around your model.
3. Zooming
The scroll wheel on your mouse can be used to zoom in and out on the modeling
environment. Pressing ZA in sequence is the keyboard shortcut to zoom to
model extents.
4. ViewCube
By clicking and dragging the ViewCube on the top right of the Vasari interface,
you can orbit your model as well. By clicking on any of the faces, edges or
corners of the cube, you can orient the camera view to a predetermined view.
You can also click and drag on any of the orientations of the ViewCube to
constrain the rotations.
5. Views in Project Browser
On the left side of the Vasari interface, you can access the stored project
views. By double clicking on the Views in the Project Browser, you can expand
the menu to show all of the saved views. By double clicking on a view, a new

Video1.1: Importing and Setting Work planes
Importing, Selection and Work Planes
Begin this exercise by opening a new project in Vasari. In this section, the exercise files
associated with each operation will show the exercise in a completed state.
Importing Files
3
Often a two dimensional CAD or raster underlay is used to guide the
layout of a model. Project Vasari is capable of importing a number of file
formats such as JPEG, TIFF, DWG, DXF, DGN, and SKP (Sketch up).
We will start by importing the CAD underlay file called “Site
Underlay.DWG” into a new Vasari project.
Under in the upper left corner > Import > Import CAD
It is important to note the various options at the bottom of the import
screen. You have the option to filter and orient the imported CAD
depending on your needs. For this exercise, set the Colors drop down to
preserve the original CAD colors, also set the Positioning drop down to
origin to origin.
The process of importing an existing raster image is very similar to the
CAD import.
Click App menu > Import > Image.
Setting Location, Weather Data and Google Earth™ Site Images
When creating a project, the location of the site can be specified in multiple ways.
Specifying an exact location is important for solar analysis and energy analysis as well as
contextual design. This location can be selected by street address, major city, or latitude
and longitude. The location is also associated with weather data used in the Conceptual
Energy Analysis. If you are looking to import a site image for sketching over top of, Project
Vasari has an embedded tool for importing Google Maps™.
1. Click Analyze > Project Location > Location or in the ViewCube >Location.
The Location Weather and Site dialog displays an interactive Google Maps™ interface
that can be navigated by searching for a city. Once in the area of the site, drag the red
cursor over the site to specify exact longitude and latitude. Note: Internet connection
required.
You must be signed into Autodesk Online Services to access weather data. The weather
data is populated with data from the 2007 ASHRAE Handbook. This option is
recommended for HVAC and mechanical work.
On the left side of the dialog, there is a list of weather stations from which all
environmental data is available. Select the weather station closest to the site. In this case,
choose weather station 59385.
4
For Project Address, enter San Diego, CA. Notice it brings you to a default city center
location. You can simply click and drag the home pin to your desired location, or you can
enter in specific longitude and latitude coordinates. For this lesson, enter in 32.71° N,
117.17° W.
Next, click Import Site Image on the bottom right side of the dialog. This will be the
underlay image from Google Maps that will come in as a textured surface and will be used
as a reference for modeling the site context as well as establishing the site extents when
massing. Note: You can change the size of the dialog to create different aspect ratios for
the underlay image. You can use the mouse wheel to zoom and pan to get the image you
want before importing.
5
The imported image may require some manipulation to get it to align more closely with the
model and CAD underlay. It is not important that it aligns perfectly, it is mainly for
reference and context.
Selecting Objects
The default command in Vasari is Modify. You can always get to it by clicking the
Modify button on the left side of the Ribbon. Or from inside other commands by
pressing the Escape key (esc). Elements are highlighted when you hover. They
change color when you select them.
Forms are made up of elements, such as faces, edges and points. You can
use the Tab key, combined with the left mouse button, to cycle through the
available elements, before selecting the one you want. Press and hold the
control key to add an object to your current selection.
Right-clicking on an element, or a blank area of the view, provides more
commands related to your current selection.
When you select an element, such as a completed mass, you will see relevant properties
presented in the Properties palette on the left. You can modify the properties of that
element, and the changes are made immediately
Double-clicking on a mass allows you to start editing it. You can move it using 3D control
widgets, or by typing dimensions.
Setting and Showing Workplanes
Exercise File
01.2 Import-select-workplane2_End.rvt
Work planes are crucial to understanding modeling in Vasari. Geometry is always
associated to some host surface or plane. Elements can be detached from constraints but
will still maintain some sort of relative offset to some particular reference plane or surface.
6
In some views, the work plane is automatically set. In other views, such as elevation and section views, you need to set the work plane. The work plane is necessary for sketching operations and for enabling tools in particular views, such as Rotate and Mirror in a 3D view.
Two ways to set a plane:
1. Select the Set Tool Within the work plane dialogue box, you can select an existing workplane by name, or by choosing to pick a plane from the modeling environment.
2. While in the Vasari 3D environment, simply select an existing reference
plane or grid. Use the “Show” tool to display existing work planes.
Reference Points
Reference points contain three reference axes which can either be set to reflect the global coordinates or the local coordinates where the point is located.
Reference Lines
Reference lines each contain four planes of reference, each of which are associated with the vector of the line. The two which lie on the line are parallel to the vector, and the end point planes are normal to the vector.
Levels
To set up levels for the project that will be shared between all of the design
options we are going to create. To do this, simply select all the reference planes
that are created by default when you option up the file.
While holding the Shift key, drag those reference planes up vertically. You can easily
change the spacing by clicking on any plane and entering a new value where you see the
current dimension. For the San Diego campus there is a 12 foot (3.6576 meters) distance
7
between each reference plane. Autodesk® Project Vasari uses these planes as floor
datums to create floors in the masses we will create for energy modeling. These are
calculated as floor to floor heights and will define the floor areas to measure. You can
create parameters that drive the distances between each reference plane so you can
explore how the floor to floor heights affect the overall project later on.
It is important to remember that all modeling in Project Vasari happens in relation to these
reference planes, so create as many as are appropriate to your project intent.
Autodesk Vasari Workshop 2012 Workshop Exercise 2: Creating and Modifying Form
Exercise 2: Creating and Modifying Form
Lesson Overview When you start working in Autodesk
® Project Vasari, you may already have a few
sketches of ideas for the campus. You should have a conceptual basis for the design,
notebook sketches and ideas. In this section you will learn basic 2D sketching and 3D
modeling skills by creating several low-rise buildings on our site based on a basic CAD
layout.
In this lesson, you explore basic techniques for using Project Vasari to set up a project
location. You will learn how to:
- 2D Sketching and 3D Modeling
- Creating Basic Mass Forms
- Manipulate Forms Using Modeling Tools
- Create Mass Floors and Area Schedules
Learning Objectives - Sketch and extrude several simple masses
- Edit mass forms in-place

Video Tutorial
Video2.0: Creating and Modifying Forms
Once the exercise file is loaded, modeling can begin.

In this example, we see a set of lines and polylines drawn in AutoCAD®
and imported. For this exercise, we want to create a series of low
buildings using the closed CAD lines as a template for the footprints.
Begin by temporarily hiding the map image by selecting the image and
pressing “HH” on your keyboard. To unhide, press “HR.”
Next, click Create Mass tool under the model tab. Using the modeling lines,
sketch the profiles of each mass footprint you wish to create, ensuring that
each sketch is a closed loop.
To extrude, select the curve and select Create Form at the top of the ribbon.
This creates a parametrically controlled form where you can use a 3D control
to push, pull, and edit the form on any face. You can perform blends, sweeps,
extrusions, and Boolean operations in this environment. For the low buildings,
this exercise will only be using the extrude commands.
When you are finished with each building, click Finish Mass.
Modifying Form
Once you have created and finished your basic building mass extrusions, you can go back
into the Mass Editor by selecting the mass object and clicking the Edit In-Place on the
ribbon.
By selecting a face individually, you can use the many modeling tools to manipulate the
surface and overall form.
Another helpful modeling trick is to hit the space bar with a surface, edge, or point
selected. This toggles between a 3D control that operates in the world XYZ coordinate
system and object-specific coordinate system, enabling you to move and edit the object
more precisely.
3D control Orientation
10
When you have successfully done this step, the model should resemble the following:
Mass Floors
After modeling and selecting Finish Mass you can
use the reference planes as datum to create floors
for calculating square footages (or meters) and
enabling the Conceptual Energy Analysis features.
The Mass Floors button is right next to Edit Mass-
In-Place whenever a mass is selected. You can
move your reference planes around to edit the
floor-to-floor heights and the model automatically
updates. Notice in the Project Browser, under
Schedules, a new Mass Floor schedule is
automatically created. Open it and see how area
totals are tracked per floor. Schedules can be
added and edited for almost any geometry or data
in Autodesk® Project Vasari.
Area Schedules
By creating mass floors, you automatically create
and populate a schedule of information based on
the floors you just created. The Mass Floor
Schedule is located in the Project Browser under
Schedules and Quantities.

Autodesk Vasari Workshop 2012 Workshop Exercise 3: Parameters
Exercise 3: Parameters
Lesson Overview This exercise will focus on the creation of several configurations of the tower in the corner
of the site. Adding parameters to the project can increase efficacy of the design process
and show design intent more clearly. Like in Autodesk® Revit
® Architecture software,
parameters can be added to make adjustments to the design or to constrain form to
particular values. We will begin by explicitly manipulating the tower to generate several
options (straight extrusion, tapered and twisted). Then we will use a parametric approach
to create similar forms. Once parametric controls are in place, we will explore how we can
quickly iterate formal options for analysis in the upcoming exercises.
Learning Objectives - Creating Tower Options: Extrude, Taper and Twist
- Adding Parameters to Control Shape
- Create Several Design Options For Analysis

Video 3.0: Parameters
Creating the Parametric Tower Mass
At this early stage of the design process, focus only on a few general parameters. Explore
different goals of our models as to not over constrain them. You will focus on exploring
height, tapering and rotation of the tower. Start by either sketching your own footprint and
extruding a mass or select the existing tower and Edit-in-Place. Add a dimension
parameter for the height by keying in DI and setting it in the Project Properties dialog.
Ensure you the work plane is correctly set to constrain the dimension vertically. Verify that
the tower height is being driven by the dimension, by trying a few different values.
13
Creating a Parameter:
Now that there is a tower in place, we want to be able to change the height with the
Parameter Properties dialog. Select the dimension you just created to drive the height of
the tower. When the dimension is selected, below the ribbon you will see a series of
options become available in the Options Bar.
In the Options bar, click Label>Add Parameter.
In the Parameters Properties dialog,
give your new parameter a name
relevant to what it is intended to control.
Make sure to select Instance and that
you group the parameter under
Dimension.
Once completed, you should be able to
control the Height (or any other
parameter you choose to set) using the
Properties dialog in the project
environment.

3-1 Parameters2_Tower.rvt
3-2 Parameters2_End.rvt
Now that you have a basic understanding of parameters in Project Vasari, we can move
on to creating a simple parametric rig to control the form of our twisting tower. Begin by
either creating a new mass within the project or creating a new mass family.
Our goal in this exercise is to create a surface with XY axis rotation controls imbedded
within its construction, from which we will loft to a stationary bottom surface (Building
footprint). To do so, we must construct the geometry to be driven by a rotation parameter.
Begin by placing a reference point at the center of where you wish the object to rotate.
For this example, the intersection of the default reference planes.
From the point, draw a reference line which originates from the reference point to an
arbitrary location off to one side. This line will be host for the model geometry you are
about to create, so its dimensions are not important. Place an angular dimension between
any axis and the newly created reference lines. Assign the dimension as a parameter as
you did in the section prior to this with a descriptive name such as “Rotation Angle.” To
prevent future issues, make sure to test the parameters as you create them.
Your model geometry will need to be hosted onto this reference line in order establish a
relationship to its rotation parameter. To do so, you must set the reference plane to
the reference line you wish to build off of.
Once you have finished drawing your hosted geometry, check to see whether the rotation
parameter is functioning correctly.
To prevent future issues, make sure to test the parameters as you create them. Your
geometry should now react to changes in the parameters they are related to.
15
Create a second level by copying and moving it up. Then copy and paste all of the objects
you just created onto the second level. This can done using the Paste from clipboard
options under the Paste tool. Select Aligned to Selected Levels and select level two.
After you have your objects pasted correctly, you need to convert your model geometry to
reference geometry in order to retain control of your parameters. Select the profiles of the
rectangles and select the Is Reference Line check box in the Properties dialog.
Next, loft the two reference profiles together by selecting them and clicking Create Form
on the ribbon. Test the twisting parameter to ensure that everything is functioning as
intended.

Video Tutorial
Video 3.3: Design Options
To test and analyze multiple forms or schemes in Autodesk® Project Vasari, use Design
Options. Design Options is a framework for modeling, analyzing, and visualizing iterations
during design. A team can develop, evaluate, and redesign building elements, specific
spaces, or discrete components while not affecting other parts of the model. For example,
on a large scale, options may test different placements of a tower and its solar effects on
adjacent buildings. On a smaller scale, design options could test alternative shading
devices on a wall. After energy analyses have been run, the results can be compared side
by side and an informed decision about the design is made. The design develops after
17
multiple studies and analyses hone in on a design specific to the formal, environmental,
cost, and design criteria laid out by the designer.
You now have a basic sketch of what the building may look like, but the next step is to
experiment with the form and explore many possibilities. To use all of the modeling
options, parameters and design options are necessary for quick changes. In this lesson,
you will set up a few variations of the tower form using design options.
Using Design Options
Design Options is a built-in feature for modeling and analysis in Autodesk® Project Vasari
to quickly explore permutations. Start with the base model, imported CAD objects, a site
model, or a blank slate.
Combining Design Options with project parameters is a great way to organize your model
and works in a similar way as layers do in other 3D applications like Autodesk® 3ds Max
®
Design software. The primary difference here is that Project Vasari automatically
categorizes all of the models components, from a conceptual mass down to the different
types of glazing. This detail enables the design options feature to be a higher level group
that can be turned on or off. When you create a parametric model within a design option
set, it is easy to copy it, make some changes, and compare the differences between
options in the Conceptual Energy Analysis environment.
Setting Up Design Options
You should now set up your project file with Design Options. In Project Vasari, Design
Options work very similarly to layers in other programs. To set them up, find the Design
Options button under the Analyze tab. You can either click Design Options or key in DO to
enter the dialog. By default, the existing modeled geometry is the base option and is
labeled.
Main Model, Option Sets, and Options
18
Adding Geometry to a Design Option
To create a set of three options with parametric tower varieties, create a new set. Label
the new set Tower Options. The first set we rename to Main Building and leave the
base mode geometry on it.
Within the Options set, create three options: Twist, Taper and Straight. Next is to create
three new views, one associated with each design option.
In the primary set with the correct corresponding view activated, place one of the tower
options. Repeat the same process for each of the tower options. Now you can toggle
between three tower options by selecting the drop down menu in the view bar at the
bottom of the screen.
Switching Objects from one design option to another:
As you go through the process, you may want to switch a mass between Design Options.
Now that you have multiple tower options and a temporary building family, you will need to
organize these into a logical set. You can either copy and paste an object into a Design
Option or add new geometry in the dialog. With these three options set up, run the
analysis tools and make an informed decision about which option to pursue.

Autodesk Vasari Workshop 2012 Workshop Lesson 4: Orientation, Sun Path & Solar Radiation
Lesson 4: Orientation, Sun Path & Solar Radiation
Lesson Overview The goal in the preliminary sun path study is to figure out where solar heat gain is most
extreme and the best way to mitigate it. This will help you visualize and make informed
decisions about materials, energy loads, and financial costs. First, go to the bottom of the
screen and turn on the solar path in the view toolbar. In this dialog, you can specify the
size of the solar path as well as the sun’s location per date and time.
Use the solar path tool to visualize basic shadows and their change over time. This path
can be animated and visualized in different ways for analysis and visualization. Once you
know how the sun is hitting your building, you can use this information to change your
design accordingly.
Learning Objectives - Setting Project Location
- Using sun path tools to analyze towers on different dates
- Visualizing sun path, animations, and shadows
- Solar radiation analysis
Exercise 4.0: Orientation, Sun Path and Solar Radiation
Exercise File
4-0 Orientation,Sunpath,Radiation.rvt
Video Tutorial
Video 4.0: Sun Path
Setting Project Position and Orientation
Often you may find when you import a CAD underlay or a site image that the project north
and true north are not aligned. Establishing north correctly must be sorted out in order to
proceed, as orientation of your buildings is essential to
producing reliable analysis results.
Begin by opening a 2d plan view of your project under the
project browser. To access the set of tools which allow you
to rotate project/true north, you are required to be in a plan
view. This functionality can allow you to view your project
and draw orthogonally while maintaining true north.
21
Sun Path Tool
The sun path is a visual representation of the sun's range
of movement across the sky at the geographic location you
specify for a project. Using the sun paths on-screen
controls, you can create solar studies by placing the sun at
any point along its daily or yearly path.
The location of the sun can be manipulated by grabbing and pulling the
graphic sun on the model or by explicitly defining a date range and a time.
To define an explicit date, click on the sun icon in the lower view bar and
select Sun Settings. In this dialog, you can set any explicit solar time for its
position. It is also possible to add and edit sun setting presets.
Preview and Export a Solar Path Animation
Within the View Options, use the Solar Path toggle to select
Preview Solar Study and define an animation timeline. Shadows
must be on to preview a solar study. To export the solar study,
select Export under the Applications menu and choose Images
and Animations > Solar Study. This will provide a dialog for the
video settings and directory before rendering out the animation.
22
Sun Path
Change the visual size of the sun path relative to the model in the properties dialog box
with the sun path selected. This does not change the behavior of the sun other than its
visual properties.
Shadows
Activating shadows in Project Vasari is done on the settings bar at the bottom of the
modeling screen. Shadows are reactive to changes in time (Solar Position).
Sun Path Settings
Options and settings for the sun path tool are located on the bar at the bottom of the
modeling screen next to the shadow button. Sun settings can be set to reflect a single
moment in time, a few hours, a whole day, or over the course of several days. You also
have the option to select certain presets for equinox/solstice or seasonal studies.
Constraining your analysis can help you better understand the solar implications during
peak load times of summer, or to perform a solar access analysis during the winter.
Solar Radiation Studies
After the Sun Path is set, we run a more precise solar radiation analysis based on the
Autodesk® Ecotect
® Analysis software solar analysis tool. Radiation analysis shows solar
heating load incident to the envelope of the
building. It displays the intensity of the solar heat
transfer and allows the user to either choose to
change the orientation of the building or add
shading to the exterior or conceptual constructions.
In Show Mass Form mode, select the masses we
want to run the Ecotect Solar Radiation analysis
on. Analyze each of your tower options.
In the respective dialog, there are options for
resolution, units, and the ability to define only
certain faces of the selection to analyze. Like other energy analysis tools, a higher
resolution analysis takes longer. Keep this in mind when selecting faces and be careful
not to analyze unnecessary geometry.
23
Analyze and Iterate
After completing the radiation analysis, the results are visualized directly on the model.
With these results, the red color shows the highest radiant heat transfer to the skin of the
building on the southern facing walls. If you decide after this analysis that there is too
much solar heat gain due to the form of the building, you can either edit the existing forms
or you can use the Design Options to try out different forms and settle on a solution with a
more appropriate amount of exposure.
Analysis Display Styles
You can adjust the visual
display styles to suit the
needs of your project.
Multiple display styles can be
useful for visual analysis as
well. Analysis Display Styles,
found under Manage >
Settings, is an option for
customizing the visual
display settings of the
analysis tools. You can
create new or multiple views and use them for different analyses while documenting your
process. These styles are available throughout the Project environment, but not in the
family editor.
Exporting a .csv file of this data is also possible, and can be exported through the Solar
Radiation analysis dialog.
After the sun path and solar radiation study, we know much more about where solar
exposure is greatest and can try a few methods to curtail energy use. Solar incident
radiation is a simple but telling tool for understanding how the form is impacted by the sun.
Roof and wall pitches, shading devices, and siting are all basic ways to lessen the impact
of solar radiation. If using photovoltaic panels, this tool can be used conversely to gain

more solar energy. In any scenario, keep in mind the context. A dense urban environment
may need different glazing or daylighting strategies at the base of the building versus
higher floors.
Since you can visually see the southern facades show the most solar gain we will adapt
our program and energy use accordingly. Arranging the types of program and conditioned
spaces in the building, based on analysis, can help energy use at a primary level. After
adjusting the energy settings by program, you will design an adaptive component with a
variable shading element to use on these solar-intensive facades.

Autodesk Vasari Workshop 2012 Workshop Lesson 5: Conceptual Energy Analysis
Lesson 5: Conceptual Energy Analysis
Lesson Overview Conceptual Energy Analysis (CEA) is a high-level analysis tool to deliver preliminary
feedback and understanding of how the model created responds to site and climatic
environment. This process can and should be used multiple times at different stages
during the design process. It works for different scales but generates a set of data most
relevant to comparing multiple design options of the same building. It will become
important to spend some time thinking about the resulting data from the analysis as Vasari
cannot speak to the implications of the new information.
Learning Objectives - Set Energy Settings and baselines for Conceptual Energy Analysis

Video 5.0: Conceptual Energy Analysis
Enable Energy Modeling
In the Energy Analysis panel, click Enable Energy Model. This associates exterior walls
with an energy envelope and glazing system to use for analysis. Once energy modeling is
enabled, use the four different Energy Model Display modes to visualize and test different
aspects of the model.
Energy Model Display Modes
Modeling, analysis, and model management all become easier when using the right
display mode. The Energy Model Display Modes are different view and selection settings
for working with the model. Under Analysis > Energy Display there are four different
options: By View, Form, Surfaces, and Zones.
26
Show Mass Form
This option displays all mass instances and forms in all views, even if the mass category
is turned off in Visibility Graphics.
Show Mass Surfaces
Use this mode for changing conceptual constructions and other energy settings for
individual mass surfaces (floors, slabs, walls, roofs, glazing, and skylights). Use Tab to
cycle through and select different surfaces and objects individually.
Show Mass Zones
For Conceptual Energy Analysis this displays individual mass zones. This allows selecting
individual zones and editing unique settings.
NOTE
The energy analysis tool in Project Vasari will not allow you to isolate an individual mass
in a project for analysis, so for this example we will be allowing it to look at all of our
masses. Typically when performing an energy analysis, you would not simulate several
buildings at once, you would do them individually. Just as a note, this example is purely to
illustrate the process of conducting an energy analysis in Project Vasari.
Appropriate Level of Detail
During the modeling process, make sure not to be too detailed. Energy modeling for many
of the quick analysis tools Autodesk® Project Vasari has to offer is best done at a very
basic level first. Adding lots of detail takes more time for testing options that may not be
used. Energy analyses are processor-heavy operations that are often rough results of
many variables. Simple models simply work better.

Creating Zones and Assigning Programs to Spaces
In this exercise, create new custom Zones in order to specify the program and
conditioning type of different parts of the main building. You will be able to choose from a
comprehensive list of use types, ranging from active storage to gymnasiums and
auditoriums. You will also specify if those zones are heated, cooled, naturally ventilated,
or mechanically ventilated.
This functionality is achieved is by creating new geometry based on what has already
modeled and cutting it out of the main building model. This performs two functions. It
creates a custom space to isolate and add more detail to as well as provides a conceptual
space specifically for running Conceptual Energy Analyses.
If you are dealing with simple, orthogonal geometry, you can use
the Core Offset option within the Energy Settings dialog. The core
offset enables you to create a perimeter zone that is used to
specify the conditioning settings for the areas closes to the exterior
facades (which typically require more conditioning) and an interior
zone.
You may also use the Divide Perimeter Zones option also found in
the Energy Settings dialog, which will divide your model by
orientation, leaving you with four zones, one per each cardinal
direction. This is particularly useful responding to the southern
orientation with a different approach than the northern orientation.
Specifying Individual Program Spaces
Once all of the zones are created there are two options. You can select an individual zone
and assign program to it by moving over to the properties dialogue and choosing a value
for the Space Type field. Alternatively, you can create a Mass Zone Schedule to have a
fast way at assigning program and conditioning type information. This will display all of the
zones created, where you can also click on a cell within the schedule and have that
particular zone become highlighted in the actual model.
28
To create a schedule, click Manage tab > Schedule. For all of the detailed program
assignments, simply open up the schedule created in the Browser.
Energy Settings
Before using specific analysis tools, setting the
project Energy Settings is a good first step. Use
the Energy Settings dialog to set global values
for the project’s location, building type, phase,
and energy model settings. Click Analysis tab>
Energy Analysis > Energy Settings. Here are
the settings used for the academic campus.
Even though these were set first, they can be
reviewed and edited at any time during the
process. Energy settings can be edited per
program space also, but this is the first step to
standardizing a base setting. These options will
be explored in Exercise 6.3.3: Changing Energy
Settings per Analysis.

Changing Energy Settings Per Analysis
After the solar analysis, you can see how the sun is affecting the mass and can take some
steps to change the design.
This exercise will cover how to control the energy settings of each surface or space
individually. Through a schedule, you will organize the facades in response to the results
of an analyzed Energy Model. This will enable you to quickly toggle and test different
target glazing ratios, conceptual constructions, and energy settings. These settings
simulate abstract factors that influence the energy model like heat generation, material
properties and insulation.
The aim is to strategically group surfaces that will need similar design solutions like
integrated solar shades or a particular material property (conceptual constructions) by
orientation.
It may become useful to create a schedule to manage all of your façade faces as they may become too complex to pick individually. To do so, start by creating a schedule that contains all of the mass surfaces in it similar to how we created a Mass Zone Schedule. This will enable you to quickly assign different conceptual constructions and target glazing percentages. A spreadsheet format that has direct interrelated connections with the model is a great way to edit program assignments iteratively. You can duplicate the model into a new design option to save your original settings while pursuing alternative options.
Alternatively you can easily change settings from the model directly by using the Tab
button to select each surface. Once selected, go over to the Properties>Setting
Properties. The advantage of creating a schedule, however, comes with managing much
larger amounts of surfaces through filtering them by type, or any other property.
As per the understanding of the Ecotect Solar Radiation Study, you can change the
amount of glazing of the areas that are the most exposed to the sun. You also have the
option to test if they are shaded or not. Since you are working on a per surface basis, you
can individually change all of the southern faces first, reducing the amount of glazing and
enabling shading.
For a full list of the changes made to each design option, open up the Mass Surfaces
Schedule.

Analyzing the Energy Model
To run a test of the options that have been set up, click Analyze tab > Analyze Energy
Model. This will send the model information to Autodesk's cloud-based service that will in
turn generate an Energy Report. The following topic will discuss how to compare multiple
analyses side by side.

Conceptual Energy Analysis Results and Compare
One of the most exciting features in Autodesk® Project Vasari is the ability to have the
assumptions and results of your Conceptual Energy Model automatically generated in a
well-organized, concise, graphic format. In addition to being able to easily visualize what
parameters are influencing the results the most, there is also the ability to easily compare
multiple Conceptual Energy Model Results. This section will highlight a few of the most
significant comparisons from this study.
Life Cycle Energy Use/Cost
Often comparing the construction cost to the lifecycle cost is an important metric for
balancing environmental design and construction. This table summarizes the estimated
energy usage and cost over the life of the building, assuming a 30-year life span.
Energy Use Intensity
Energy use intensity (EUI) is a per-floor-area unit of measurement that describes a
building’s energy use by area. EUI represents the energy consumed by a building relative
to its size and as such can be informative when comparing options of different sizes.
Electricity EUI refers to source energy use intensity, focusing on electricity required to run
the building. Fuel EUI represents the total amount of raw fuel that is required to operate
the building. Total EUI sums these two and incorporates all transmission, delivery, and
production losses, thereby enabling a complete assessment of energy efficiency.
31
Generating a Conceptual Energy Analysis
To use the Conceptual Energy Analysis (CEA) feature, you must sign in to
Autodesk Online Services by clicking Sign In in the top-right corner of the application
frame. This is your Autodesk ID and allows you to sign in to the Labs energy analysis
features. The CEA tool uses information from the Autodesk servers to analyze your model
and generate results.
After preliminary analysis and energy settings at in place, click the Analyze Mass Model
button under Analyze > Energy Analysis. An alert appears in the bottom-right corner once
the analysis is complete, or view the progress by clicking the Results and Compare
button. The left sidebar displays completed analyses and the progress of in-progress
analyses sent to the Autodesk server.
View Results and Compare
You can display multiple analyses for side-by-side comparisons using the Results and
Compare tool. This dialog shows all of your analyses and shows results individually or
side-by-side. Use Ctrl + Click to select multiple analyses for comparing in the same
window. This is a great way to see how explicit changes in the design, whether a material
change, a form change, or something completely different, can influence the cost, energy
consumption, or metrics of the project.
A Note on Accuracy & Detail in CEA
It is relatively easy to analyze your model and get back results, but what is more useful or
interesting is when that data is used to help make particular design decisions. The reality
is that the best option may not always be the lowest energy use or the most efficient, but a
tradeoff between multitudes of conflicting options.
Although the numbers coming from the analysis may become more accurate with more
detail, there is a point of diminishing returns. Don’t overload the model and more
importantly, the results compared are most meaningful only in relation to themselves.

Communicating Analyses: Representation & Graphic Settings
Autodesk® Project Vasari allows you to generate a
building information model and energy model
simultaneously. This lets you not only share your
work with others in file formats that they can use,
but also allows for sophisticated visualization
settings that make your analyses really come to life.
Graphics Display Styles
It is important to be able to clearly communicate
your design and analysis. Project Vasari has a
number of graphic display settings, including the
ability to turn on or off Analysis Display Styles.
Under Manage > Settings is an option for
customizing the visual display settings of the
analysis tools. You can create new, multiple views
and use them for different analyses while
documenting your process. These styles are
available throughout the Project environment, but
not in the Family editor.
33
Visibility Graphics
You can use the visibility graphics tool (keyboard shortcut VG) to manage the way in
which any set of objects in your file are displayed. Here you can filter, group, and change
the way Vasari displays your objects in specific sheets, renderings, and in the viewport.
Communicating Your Work: Export PDF, Images, and gbXML
Export images from the analysis and a PDF of the data in the Results and Compare within
the dialog. For visuals of the model at different times of day, solar radiation analysis, or
other results specific to the mass, Export Images and Animations through the Application
menu.
An exported gbXML file contains all of the heating and cooling information for a project
according to the gbXML file structure. GbXML is an available option to communicate with
third-party analysis tools to help leverage information about the model’s energy
consumption characteristics. This functionality enables you to hand off your Conceptual
Energy Model to an energy specialist, for example, while you continue to refine your
design.

Assessment
After all the modeling, set up, and energy reports in the prior lessons everything is starting
to come together. Take this time to explore and compare different assumptions. Keep
track of the changes you are making by clearly labeling your analyses with the variables
you are changing. Work towards isolating a particular variable to understand how it is
affecting the whole model and build upon that knowledge. Here are some questions you
can now answer with a few clicks of the mouse.
35
What if you change all of the glazing ratios to 10%?
In this case, you will most likely see changes in which element is the largest
consumer of energy in the building. Because of the mild San Diego climate,
you are able to use higher target glazing percentages, but by decreasing them,
the amount of solar radiation that penetrates the building’s envelope is
decreased. This means that most of the heat that must be exhausted from the
building will be coming from the occupants. This may reduce the Energy Use
Intensity, save tens of thousands of dollars over the 30 year lifecycle of the
building, but it also means fewer views and may inadvertently create the
necessity to turn on the lights during the day. In this scenario you are getting to
the heart of what performance based design is all about: balancing and
tradeoffs.
How does the conditioning of spaces in different climates affect the annual
energy use? How do conceptual constructions affect energy use also?
Setting the HVAC type for different spaces changes the energy needed to heat
and cool the space over the year. Conceptual constructions are Project
Vasari’s method of adding a performance characteristic to a wall. This accounts
for R-value, and as such the heating energy performance of the building.
36
What would be the ideal height for the tower option?
The reason why you used a parametric tower and optional extra buildings was
to see a tradeoff in play. As you increase the tower height, you add more
conditioned space. However, there is a different environmental cost associated
to different program and even adding the same amount of space in a different
program type may change the results. Consider program type as well as
surface area in different design options.
Is EUI or Life Cycle Energy Cost a better metric to use for lowering energy
use?
Similarly to the EUI, looking at one number without context will not give a clear
answer. The second option is cheaper, but also uses more fuel over the life
cycle. How can this be? Fuel is relatively cheap, but also probably comes at the
cost of a higher carbon footprint. Consider which factor is most important to the
project when deciding on final solutions. Skylights may also make a space
more enjoyable, another factor that can be measured by no number.
What is the best way to look at multiple variables at once?
Like any good experiment, it is best to compare only one variable at a time.
These values are also most meaningful relative to themselves. Focus on a few
individual goals and measure specific differences in a similar model.
Monthly GBS Data
Monthly figures can be
Monthly GBS data does not represent the peak loads used for sizing of
equipment. These charts also do not represent loads caused by ventilation air,
which can have a significant impact in densely occupied buildings. To reduce
cooling and heating load in future iterations of your project, you can use the
monthly graphs to identify the critical components to building energy use.

Autodesk Vasari Workshop 2012 Workshop Lesson 6: Ecotect Wind Rose and Wind Tunnel
Lesson 6: Ecotect Wind Rose and Wind Tunnel
Lesson 6 Overview Understanding the prevailing wind patterns of your project site can be useful when it
comes to designing ways to take advantage of natural ventilation or to screen occupants
from uncomfortable windy conditions. The Project Vasari wind tunnel and wind rose tools
allow you to study the local wind conditions and simulate the physical interactions of wind
and your design.
Learning Objectives - Visualizing Wind Direction and Speed
- Wind Tunnel Analysis on Different Towers
Suggested Exercises
Exercise 6.0: Wind Rose Visualization
Exercise File
6-0 Wind_Start.rvt
Video Tutorial
Video 6.0: Wind Rose and Wind Tunnel Visualization
Wind Rose Diagram From Weather Data
The wind rose is a versatile tool for visualizing wind patterns for your specific site. You are
able to limit the analysis period by year, season, month, week or day, allowing you a wide
range of controls depending on what is important to your project.
Begin by ensuring that you are logged into Autodesk Online Services with your Autodesk account in the upper right hand area of the Vasari application frame. This enables Vasari to access wind data from a weather file associated with your site.
The next step would be to ensure that you have your site location set correctly and a weather station assigned. You should pick the weather station that is closest to your site. Next, activate the Ecotect Wind Rose tool, which is located under the Analyze tab.
39
The wind rose interface allows you to choose between a number of Google maps underlays. The default mode is set to display yearly average which will allow you to glean the general wind pattern of your site.
To control the analysis period, click on the Advanced time/date selection. On the bottom of the dialog, you will see the interface for narrowing your wind visualization period. Once you have a desired wind rose diagram selected, you can import as a family into the
project by pressing (Send wind rose to BIM project).
40
Reading a Wind Rose Diagram
To understand the diagram, you must be able to read three pieces of information simultaneously.
Velocity
Wind speed is indicated by the color of the region on the diagram. The units can be
toggled at the bottom of the dialog box between Knots, Meters/sec and Km/hr.
Unfortunately, there are no settings for imperial units.
Frequency
Each of the rings in the diagram corresponds to a scaled percentage of the analysis time
which the wind is blowing at a certain velocity from that specific direction. The frequency
reading is along the south axis of the diagram and will scale automatically.
Direction
Wind direction can be understood as the direction from which wind is blowing. The
diagram displays direction according to cardinal directions.
Ecotect Wind Tunnel
The Wind Tunnel feature can be used in conjunction with Ecotect Wind Rose analysis to dynamically simulate the impact of wind speed and direction on your projects. This prototype plugin provides a simplified computational fluid dynamics simulation that provides designers and engineers with a virtual wind tunnel to gain an insight on aerodynamic effects early in the design process. Main uses for this tool are:
Exterior Air Flow: 2d and 3d tools provide a highly visual understanding of how air will flow across your building and site.
Pedestrian Comfort: 3D simulations of key airflow circulation paths to provide an indication of the potential impact on pedestrian comfort.
Ventilation Boundary Conditions: 3D simulations of air flow across buildings to estimate the external pressure envelope.
Preliminary wind loading calculations Begin by clicking Analyze tab > Ecotect Wind Tunnel. The wind tunnel tool is a stand-alone module which imports all visible geometry into its analysis environment. If you wish to exclude anything from the wind tunnel analysis, hide it before activating the tool.
41
There are two ways of controlling the settings for the wind tunnel, either using the compass which hovers in the modeling environment, or using the sliders and toggles on the bar to the left. Like the wind rose tool, the wind tunnel tool only displays in metric units. Wind Rose
The wind rose associated with your site can be applied to the wind tunnel compass by checking the wind rose box under Model Display. It will display the current wind rose analysis settings, and will update as you change it. 3D Volumetric
The Wind Tunnel Tool can be set to display data “volumetrically” which shows the impact of wind in three dimensions. The 3D functionality has a number of ways to create wind visualizations, all of which can be toggled under Display settings. 3D Axis
Changing the orientation of the analysis plane from horizontal to a vertical setting will allow you to view wind behavior from an elevation perspective. This can be found under 3D Axis in the 2D Grid Slice dropdown box. To modify your model geometry based on the airflow simulation, close the Wind Tunnel feature. Then edit your model(s) in the Vasari modeling environment and then reopen the Wind Tunnel tool to iterate the analysis on your revised model geometry. Only visible geometry will be included in the wind analysis, so ensure that only vital geometry is included, otherwise the simulation performance may be affected. Experiment with the calculations and your conceptual models to optimize potential air flow impact. Setting the 2D and 3D Grid Boundaries
The size and shape of the bounding volume and its relationship with the geometric model can have a significant impact on the calculated air flow. The air flow calculation knows nothing beyond the boundaries of that volume; it is an absolute limit. If you create a grid that is too close to the side of a model, the air will be
42
artificially squeezed up against that volume boundary. In reality, that air would have been able to expand much further into the space beyond, but instead it is forced through a small gap that will likely result in a localized area of high pressure and artificially increased air speed. This means that a 2D air flow analysis considers only those parts of the geometry that it actually intersects, and uses only air flow paths that exist within that 2D plane. If any geometry lies slightly outside that plane, both it and its potential turbulence effects are effectively ignored. When the analysis grid extents are properly set up, you can see the difference in results in that it alleviates areas of high pressure which occur between the model masses and the grid boundary.

Autodesk Vasari Workshop 2012 Workshop Lesson 7: Divided Surfaces
Lesson 7: Divided Surfaces
Lesson 7 Overview Project Vasari can divide a range of surface types (planar, ruled surfaces, revolved
surfaces, and double-curved surfaces) to rationalize the surface into parametric buildable
components. This tool can quickly and easily create a means of applying controllable
patterns and panels to any mass surface.
Learning Objectives - Create various paneling options (UV, floor plates, reference planes) - Applying default patterns and panels

Video 7.0: Divided Surfaces
Dividing Surfaces
This exercise discusses the steps necessary to control the way in which surfaces are
subdivided, patterned, and rationalized. The Pattern Based Family loaded into the project
will be instantiated on the selected subdivided surfaces. You can control these surfaces
with a series of parameters that affect the spacing and number of U and V divisions. This
creates different conditions for how the curtain panels will display and perform on the
surfaces we are subdividing per different parts of the project.
For example, one solution may be to drive the amount of glazing in a panel parametrically based on the amount of solar radiation it will receive. The parameters used to drive the number of subdivisions will help enormously to test different panel types, sizes, and orientations.
44
Begin by opening the 7-0 Divided Surface.rvt project file.
We are going to be focused on the tower for this
exercise by creating the control surfaces from which a
curtain panel family will be hosted.
Under the Analyze tab> Design Options, ensure that
the correct tower design you wish to focus on is
activated. Once that is done, select the tower and click
Edit Family, from here we can directly edit the attributed of
the tower design. When we are finished, we will load the
newly attributed tower family back into the original project
environment.
When you are inside the tower family, isolate your selection to the vertical walls by holding the control button to multi-select and the tab button to cycle through selection possibilities. Once you have the vertical walls, click Divide Surface on the ribbon.
The UV grid acts as a guide in patterning the surface. Manipulating the divided surface also manipulates the parametrically dependent patterns and components. The vertical walls will be divided according to the default U V spacing. Grid settings are located in the Properties dialog when you select the divided face. Changing the U values will affect the horizontal profiles, where the V values control the vertical profiles. UV lines can be controlled by a fixed Number whereby it will evenly space across the face, or you can choose to control them using a fixed distance, where they will be drawn at every increment which you set. You can control the rotation of the UV grid lines by specifying an angle in the Properties dialog. U and V angles can be controlled together by changing the All Grid Rotation or individually by changing the Grid Rotation under the corresponding U or V Grid controls. Custom UV Grid
You can also divide a surface by using intersecting 3D levels, reference planes, and curves drawn on reference planes. To do this, begin by setting up some reference geometry. In this example, reference planes were used as our intersection geometry. To begin creating your custom UV grid, select the specific face you want to customize and click Intersect. Next is to select the intersection geometry, which in this case are the reference planes. To complete the operation, click Finish.
Set Ref. Planes
Intersect face w/ Ref. Plane

45
Applying Default Patterns and Panels
Now that you have your means of controlling your patterns set in place, we can begin to assign some default patterns and panels to the surface. Select the face(s) which you want to apply patterns to and select the pattern drop-down menu in the Properties dialog on the left.
Now that you have a pattern applied to the surface, make sure to test that the grid and pattern updates to changes you make in geometry.

Lesson 8 Overview Now that you have established a framework for surface rationalization, you can begin to
get creative with what you choose to host to it. The default patterns tend to be simplistic
and may not accurately represent your project ambitions in the way you imagined. Luckily,
you are able to create custom parametric curtain wall family panels which will conform
themselves to the grid of your divided surface.
Learning Objectives - Create custom curtain wall families - Instantiate your custom panel to your surface grid

Curtain Wall Family
Begin this section by creating a new family. You will be prompted to choose between 3 choices of family templates. For this exercise, choose Curtain Panel Pattern Based. This will open a template with reference lines and reference points which you can use to create your panel. Pattern Grid
The underlying grid can be changed by selecting it, and changing the pattern type in the properties dialog drop down menu on the left. These provide the ability to make a panel based on a predefined pattern. For this exercise, we will choose the Hexagon pattern as the basis of our panel construction. We will be creating a simple frame with parameters to control the patterning uniformly across our system as well as locally on a frame by frame basis.
47
Building Your Panel
Start by placing a point anywhere on the reference profile of the hexagon. Next, draw a reference rectangle which is hosted to the point you just created. Ensure that you have the reference plane set correctly to the point. To be able to have control of the frame size, dimension your hosted rectangle.
After you dimension the rectangle, select each of the dimensions and assign a relevant “height/width” parameter to be able to vary its size in the project environment. The next step is to sweep the rectangle about the hexagon to generate the form of the frame. To do this, multi select the hexagon and the rectangle and click the Create Form.
Finish the panel by creating a glazing infill using the inner edge as a boundary. You can either draw a new boundary along the inner edge of the frame or you can multi-select the existing edge. Either way, once finished, click Make Form to generate the glazing panel. You can edit the material by clicking the panel and changing the material type in the properties dialogue box on the left. Once you have made it to this point, you should check to see if your panel functions correctly. Select the underlying grid and alter the dimensions on the left. If all is well with your panel system, it should have updated along with the grid dimensions.
Loading a Family
When you have finished testing your panel, you can load it into a project to be applied to your divided surface. For this example, we will be using the twisted tower example called “8-1 Divided Surface_ Tower.RFA”. Make sure this file, or another file is open for you to load this family into. When ready, click Load Into Project. If prompted, select the project which you want this family to be loaded into.
48
Assigning Custom Pattern Families
In the tower family, select the divided surfaces which you intend to apply your custom pattern to. In the upper left of your screen click the pattern selection dropdown and scroll until you find the family which you loaded. Note
Applying this family to a doubly curved surface will cause it to break as it cannot reconcile the glass infill panel to the surface geometry. Use this panel family only with non-compound curves, or go into the family and delete the glass.
To alter the parameters of your panel, you can either double click on the family in the project browser and change values there or go back into the panel family and alter the parameters directly. By creating and assigning a Type parameter, you can control your panel form globally, by making it an instance parameter, you edit their values locally.

Lesson 9: Adaptive Components
Lesson 9 Overview
The Adaptive Component functionality in Project Vasari is intended to work in conjunction
with the pattern-based curtain panel tool. This functionality is designed to handle cases
where components require more flexibility to adapt to many unique contextual conditions.
For example, adaptive components could be used in repeating systems generated by
arraying multiple components that conform to user-defined constraints. Adaptive
components can also be useful for filling in end panels which the pattern based panels are
unable to create.

In this section we will be taking a look at ways to deal with these types of issues which require a bit more flexibility and custom input from the user to resolve these unique contextual situations.
Start by opening the “9-0 Adaptive Components.rfa” project file.
which will act as the host for our adaptive component. Then click New >Family, to open
an “adaptive component” template.
Placing Points
Place 3 points in the modeling environment, location is not important for this step. These points will be our adaptive component reference points, from which the flexible panel will be created.

Adaptive Points
Next step is to make these points “Adaptive.” To do this, select the points and click Make Adaptive on the ribbon. The Make Adaptive command only displays when you have points selected. The order in which you create the points is important as this will dictate the order in which you must place them in the project environment. Once you have made your points adaptive, you will see the ordering by which you created the points displayed above them. The framework of this panel will be created using reference lines. Make sure to have 3D snapping turned on and the Make Surface from Closed Loops option turned off.
Similarly to the section on custom pattern based families, place a point on one of the lines from which you will create a hosted rectangle. Make sure to set the reference plane to the point before you make the rectangle. Add dimensions to the rectangle for both the depth and width. Next, parameterizing both dimensions to control each panel attribute and create the frame by sweeping the rectangle along the reference lines using Create Form. Finish the panel by creating the glazing panel in the center either by multi-selecting the boundary or drawing in new reference lines and assigning a glass material. Now you can test your rig by selecting one of the points and dragging. You should see everything update in response to the change in location on the reference point, as they are the reference to which everything is built upon. When you are satisfied that everything is working as intended, load it into “9.0 Adaptive Components_Start”. Placing Panels
Before you begin placing the panel, we need to change a few settings. First, select the divided panel surfaces and ensure that the Border Tile setting is set to Empty. When set to Empty, Vasari will not create partial panels and trim them at the edges. This is not the job of the adaptive component you just created.
Next, we need to turn node points on for reference when placing the adaptive panel. Node points show the boundary conditions of the panels. To activate this, select an individual divided surface (one at a time for this step) and activate the Surface display mode in the upper right of the ribbon.
51
The next step requires a bit of blind faith, as the button to activate the nodes is not directly visible. With the divided surface selected and surface display activated, hover your mouse over the bottom right corner of the Surface Representations panel. A small button will display.
When you click this button, a Surface Representation dialog displays. Click Surfaces tab, select the Nodes check box and press OK. Now that you have everything prepared, we begin to place some panels. You can find your loaded adaptive panel in the project browser under generic families. When you have this located, drag and drop it into the project, this will begin the placement process which consists of locating the host points of the panel on the pattern based family surface. Make sure to click on the node points as the host points. This process is made easier if done from the back of the surface as the pattern based family is also hosted here as well and might be obscuring the node points.
52
Depending on if you clicked in the correct order (clockwise vs. counter clockwise) your panel may have been hosted behind the surface as opposed to on top of it with the pattern based family. Instead of deleting the panel, you can select the panel and select the Flip check box in the Properties dialog. This option flips the directionality associated with this panel. NOTE:
It is important to note that our adaptive component does not have a relationship to our existing curtain panel component, so if you were to change the one, it will not affect the other. You will need to make sure to manage both systems independently of one another.
