Project Engineer HVAC Overview
Automating the HVAC Layout and Design Workflow
Project Engineer HVAC (PE-HVAC) is acomprehensive application that automates thelayout and design of air distribution systems.Appropriate for the design of both commercialand industrial buildings, the product enables youto work interactively with architectural drawingsto accurately and efficiently place heating,refrigeration, and air distribution equipment, aswell as route complete duct systems. Placementand routing capabilities are complemented withsophisticated analysis routines that interactivelysum airflows, size ducts, and calculate ductgauge requirements.
PE-HVAC placement commands integrate with a library of graphicssymbols containing a complete array of HVAC equipment, includinggrilles, registers, diffusers, fans, cooling and heating equipment, andterminal devices. Defined in Eden parametric language, equipment symbolsintegrate with online catalogs that supply device-specific intelligence.Customized with your own information, these catalogs are freely accessibleboth within and outside the design environment. You can work withmultiple catalogs during a project, as well as review, report, add, change, ordelete entries at any time. In addition to Eden symbols, the softwareprovides a library for standard graphics cells. Using MicroStation drawcommands to create your own HVAC equipment graphics, you can quicklyand easily populate this library, even with the most unusual devices.
Unique as a modelling system, PE-HVAC extends traditional layout anddesign from a flat, 2-D environment to the visually rich world of 3-D.Beyond the purely visual benefits of 3-D, the extra dimension ofintelligence opens new avenues of analysis: with elevation (z) values, youcan generate accurate equipment schedules and material takeoffs for costestimates. As part of its modelling routine, the software automaticallyplaces predefined fittings as it reads intelligence from duct and equipmentgraphics, though you may interactively place fittings of any type where youwish.
The software provides a flexible environment for altering HVAC designs.Manipulation commands enable you to extend and shorten ducts, as well asspecify intersections. Traditional move-copy-delete manipulations can beinvoked on single or grouped elements. Duct shapes can be changed torectangular, round, or oval. Insulation can be quickly added or removed forentire groups of ducts. Review and edit commands compose an open,interactive environment for making changes to attribute data associated withHVAC graphics.
11
Project Engineer HVAC Overview – April 2002________________
Relational databases serve as PE-HVAC’s repository of catalogand project data. Integrating with sophisticated data managementfunctions, the software enables you to interrelate designinformation and pose complex queries to generate material reportsand equipment schedules, as well as perform analyses. Usingproject data, you can create annotation labels for drawings. Thesoftware allows you to specify both the contents of labels andwhere they appear in drawings. Additionally, equipment schedulescreated from database information can be placed in drawings andedited to meet individual requirements. Construction drawingsfeaturing 2-D, top-view perspective are produced as a by-productof 3-D designs – a process requiring a single command toggle.
A Brief History
PE-HVAC has its origins in an application called "HVAC" that premieredin 1985 as part of Intergraph’s Engineering Production Design Package(EPDP) suite of products. HVAC was VAX-based and designed to exploitIntergraph’s IGDS graphics environment and the DMRS data managementsystem as a 2-D drafting tool that tracked 3-D intelligence, but did notdisplay it. Modelling operations required a companion program, which ranoutside the design environment. In 1989, Intergraph began a redesign ofHVAC, preserving its former heritage while broadening its capabilities todirectly embrace modelling. Intergraph also took this opportunity to extendthe product’s functionality to embrace a wider scope of HVAC engineering,particularly with respect to design. As a result, the product emerged on anew platform with a new definition and a new name. It became "ProjectEngineer HVAC," a UNIX-based product with comprehensive functionalitythat encompassed not only 3-D modelling, but also analysis. Anotherimportant feature of the new PE-HVAC was a library of componentsdefined with Eden parametric language.
PE-HVAC development in the early part of the 1990s refined many of theenhancements and productivity extensions pioneered in the previous decade.The Eden component library was enlarged to include ASHRAE andSMACNA fitting types. Additionally, the software’s analysis routines wereembellished to provide more sizing options. A duct calculator, in particular,was added, proving an invaluable tool for optimizing duct size to designcriteria. A duct gauge calculator was also added to optimize sheet metalthickness to static pressure values. Of particular import was the addition ofthe velocity pressure sizing method to duct route analysis options. Thisfeature, which balances static pressure distribution at duct junctions, wasprovided to optimize design of industrial exhaust systems. Developmenteffort today is focused on further productivity-enhancing features, but witha simplified user interface. Supporting this effort, Intergraph has widenedthe operating environment of the product to include Windows NT, fromMicrosoft. By making PE-HVAC more accessible and widely available on
12
Project Engineer HVAC Overview________________ both UNIX and Windows NT platforms, it can be exploited moreeffectively by mechanical engineers, facilities managers, and other buildingprofessionals.
MicroStation Foundation
PE-HVAC is based on MicroStation and incorporates all its 2-D and 3-Ddrafting features. These embody numerous graphical elements, such aslines, shapes, arcs, circles, and curves. Each element is displayed with aline weight and style (solid, dashed, etc.), as well as a color that you select.Element modification commands are also incorporated, including copying,deleting, moving, rotating, and scaling. Cell libraries, which store graphicalsymbols, can be reused within and across projects. Display commands letyou zoom in and out on screens, as well as shift views in various ways.Further, the software implements reference file capabilities, which enableyou to partition large files and implement parallel workflows acrossdisciplines.
Automatic Level Assignments
The software automatically defines discrete levels and line features (colors,line weights, and line styles) for the various aspects of HVAC systems.Registers, diffusers, and grilles, for example, are each placed on a separatelevel, with a distinct line color and style. To help control graphics densityand conserve computer resources, levels can be turned on or off to displayonly the elements needed. The software provides flexible control over leveland symbology assignments; for instance, you can customize levels and linecolors to differentiate proposed renovations from existing facilities. Plotscan be generated from individual or collective data sets.
3-D Layout
While Eden equipment symbols appear in 3-D as they are placed, ducts arelaid out in single-line mode. When initially placed, they appear as singlelines terminated with appropriately shaped cross sections. After layout, aone-step modelling routine quickly redraws duct graphics in full 3-Dperspective according to the shape specified. In addition to 3-D display, themodelling process also generates intelligence that is integral to analysisoperations.
13
Project Engineer HVAC Overview – April 2002________________
Graphics Intelligence
Tightly integrated with the PE-HVAC command environment is acomprehensive attribute system that links user-definable parameters toHVAC features. Called userdata, this intelligence proves invaluable to thesoftware’s analysis and reporting functions. It is tracked by means ofrelational databases. Database manipulations are carried out in conjunctionwith Intergraph’s relational database system, RIS. This system provides ageneric, syntax-free gateway to industry-leading relational databasemanagement systems, including Ingres, Oracle, and Informix. Attributedata can be defined and recounted easily by means of intuitive, forms-basedinterfaces. As elements are placed, only minimal data is required. Moreattribute information can be added at any time – the environment for editingis equally flexible. It is possible to use PE-HVAC in a purely draftingcapacity to rough-in designs quickly without assigning attributeinformation.
On-line Catalogs
On-line catalogs provide HVAC equipmentselections that may be placed in designs.Catalogs represent a combination of Edensymbols and attribute information, which iscontained in reference databases. The softwareis delivered with a variety of default databaseentries for various equipment types. Theseentries can be used unaltered or easilycustomized to reflect specifications from vendorsof your choice. You can review, add, or removedatabase entries at any time, either inside oroutside the graphics environment. Additionally,you can assemble multiple catalogs, organizingeach to meet specific requirements. For instance,you might create catalogs containing discreteequipment like diffusers, coils, and dampers, orcatalogs containing an amalgamation ofequipment used for a specific project.
Referenced Floor and Ceiling Plans
To speed layout and improve design accuracy, PE-HVAC references floorplans and reflected ceiling plans from architectural applications. Designfiles from third-party applications can be translated using Intergraph’s DXFtranslation software. For even greater productivity, you can benefit fromthe seamless integration between PE-HVAC and other members ofIntergraph’s building design and management suite of applications.Intergraph’s unique reference file capabilities support concurrent workflowsamong related architectural disciplines, enabling members of project teamsto view each other’s drawings over the network while work is in progress.

Project Engineer HVAC Overview________________
Devices
Placing devices in PE-HVAC centers on an intuitive, forms-based interfacethat provides fields for selecting devices from on-line catalogs, definingtheir attributes, orienting them in 3-D space, and placing them in a layout.Catalog selection queries a reference database, allowing you to specifysearch parameters. The software generates a list of devices that satisfy yoursearch criteria. It also delivers default userdata profiles for each equipmenttype. You can edit these profiles or use them unaltered. You can also copyprofiles to new database records and edit them appropriately. Userdataprofiles include information such as device type, airflow rate and range,width-depth-length values, and model number. You can define additionalattributes for equipment takeoffs, such as manufacturer, system ID, andcost.
Customized Graphics
Complementing the library of Eden-defined devices bundled with PE-HVAC are commands for creating your own graphics. You can use Edenutilities to create graphics with parametric definition or MicroStation drawcommands to create basic 3-D cells. MicroStation graphics can be convertedto PE-HVAC elements with userdata cell structures. Central to userdataintelligence are place points, which track information about the size, shape,and air flow direction of inlet and outlet connections, as well as deviceorientations. You can set the symbology of these cells to mirror that ofEden-defined graphics. Placement strategies for both types of graphics areidentical.
Orientation Tee
Beyond selecting devices and defining their attributes, thedevice placement interface features an orientation tee thatenables you to place devices so that airflows are in theright direction and ducts can hook up properly. The teedefines three axes: primary, secondary, and normal. Theprimary axis defines airflow direction, the secondarydefines device width, and the normal defines devicedepth. To situate devices at appropriate angles, the teeprovides rotation around each axis. Also featured with theplacement interface is a reference plane form, which setsplacement elevation. Actual placement is interactive.You can place devices individually or in matrices (bydefining x and y directions and spaces between devices).You can also connect devices to existing ducts, fittings, orother devices.
15
Project Engineer HVAC Overview – April 2002________________
Ducts
PE-HVAC places rectangular, round, flat-oval, or flex ducts in single-linemode. The single-line graphics track userdata that is elemental to a varietyof operations, including placement, sizing calculations, surface modelling,reporting, labeling, and drawing extraction. Route lines can be specified torepresent the corner, top, bottom, or center of a 3-D duct model. Theyappear in dynamic mode, allowing you to visually verify their path beforeactually placing them.
Duct Sizing
Integrated with the software’s duct placement interface isa powerful duct sizing calculator that presizes new ductsor resizes existing ones. Sizing calculations are based onairflow values, maximum and minimum velocities, andmaximum friction loss rates, which are extracted fromdevice userdata. You can further optimize sizingcomputations to specific design conditions by definingnumerous constraints. The most common sizing methodsinclude equal friction and static regain. For removal offumes, vapors, and particles, PE-HVAC is equipped toplace hoods and collectors. An industrial ventilationroutine calculates duct sizes for these systems. By default,computations are based on ASHRAE calculation methods,though you can implement any standards you like. Thecalculator generates a report file containing recommendedduct sizes for a given set of design criteria.
Elevation
Beyond device placement, the reference plane form also has important usesin placing duct systems. Allowing you to establish auxiliary coordinatesystems, the form can be used to set elevations for any of the three availableplanes (xy, xz, and yz), providing both vertical and horizontal control. As aresult, you can ensure that devices and duct systems are placed atappropriate levels with respect to ceilings, floors, or walls.
Routes
Much like the orientation tee that accompanies device placementcommands, the duct placement interface features a route control form thatdefines routing parameters. In addition to allowing you to route freely in3-D space, the form enables you to force duct routes to specific angles andchange routing orientations. For example, you can set angles to specifybends or change orientation to route along angled walls. Another routingaid is the dynamic axis lock, which constrains duct routes to specific xy
16
Project Engineer HVAC Overview________________ axes. With this lock activated, you can snap to points in a design todetermine the path or terminus of route lines. This function is particularlyuseful for precision routing where you need to route parallel to or on top ofdesign elements, or perhaps route to a certain point.
Duct Attributes
Beyond defining routes, the placement interface also defines duct attributes.Functioning as a catalog entry form, it allows you to copy, modify, or createreference database records pertaining to ducts. The form features numerousattribute fields. You can define the size and shape of ducts, as well as theservice condition (supply or return). Additionally, you can specify apressure class of high, medium, or low to regulate the software’s automatedfitting placement and sizing operations. Also, you can indicate systemstatus to distinguish whether ducts are proposed, existing, or to be removed.Further, you can define duct and insulation material, as well as materialthickness.
Device Hookup
The software’s hookup operations require minimal input – a simpleselection of device, duct system and shape, and airflow direction. Thesoftware automatically projects an orthogonal route between ducts anddevices. The command sequence operates on a device-by-device basis. Itreads dimensional information off device place points. For instance, if adevice has a round neck, the software routes a round connecting duct thatmatches the device’s neck dimensions.
Fittings
PE-HVAC provides two methods for placingfittings: they can be placed automatically inmodelling operations, based on duct layoutintersections; you can also place them manuallyat specific locations and orientations.Automatically placed fittings have the same sizeand shape as underlying ducts. The softwareextracts fitting intelligence from duct userdata;relevant attributes include size, shape, servicetype, pressure class, and airflow rate. Fittingtype is determined from a default table, whichincludes ASHRAE and SMACNA fittings. Thistable is easy to reconfigure, allowing you tospecify the default fittings of your choice. Youcan also specify transitions and reducers forautomatic placement where necessary.
17
Project Engineer HVAC Overview – April 2002________________ For special conditions or locations, you can individually create and placefittings using manual placement commands. As with devices and ducts,user-placed fittings are cataloged in reference databases. Standarddefinitions, bundled as part of the product’s default reference entries, can becopied or modified as necessary for your own design purposes. Thesoftware also provides fitting graphics in both Eden and cell libraries. Inaddition, you can create your own graphics using PE-HVAC’s Eden utilitiesor MicroStation draw commands. Each fitting has place points that carrythe width, depth, shape, orientation, and direction (inlet or outlet) of itsconnections. Orientation is controlled with an orientation tee.
Modelling
Featuring a straightforward interface, modelling commands are simplyinvoked and quickly executed. The software reads shape and dimensionalinformation off duct userdata and constructs 3-D duct surfacesappropriately. It also evaluates intersecting ducts and places the correcttype and size fittings at intersections. Models can incorporate centerlines,insulation, and linings. Further, they can be generated in design mode aspermanent fixtures in a file or in draft mode for temporary display.
As part of the modelling process, the software evaluates design data andsenses error conditions. It flags questionable elements with error markers.A show errors command reports the nature of errors, allowing you toquickly review and edit design inconsistencies.
Manipulating Graphics
PE-HVAC provides a flexible environment for manipulating graphics. Youcan manipulate duct route lines, cross sections, and the ducts themselves, aswell as fittings and devices. You can also change duct surface graphics.Manipulation commands provide basic copy-move-delete operations forindividual elements or groups of elements. These operations apply not onlyto graphics, but also to associated userdata. Groups consist of individuallyidentified components, components in a fence, components in a view, or allcomponents in a design file. In addition to basic manipulations, thesoftware provides specialized commands that join and break ducts, as wellas extend existing duct routes to new locations or to specified intersections.Also available is a command to reverse the airflow direction of duct routes.
18
Project Engineer HVAC Overview________________
Reviewing and Editing Design Data
With PE-HVAC, you can always look at your databasesto review and edit userdata. You can selectively reviewand edit single elements or groups of various elements.With groups, you step through each component’s userdataone sheet at a time. Selective group functions are appliedcollectively to elements of one type, such as ducts ordefault fittings. Unlike selective edit-review functionsthat apply to one element at a time, group edit functionseffect changes in one sweep – a particularly powerful toolfor edits of system-wide scope.
The dynamics associated with changes to userdata arevaried – some graphical elements automatically reflectuserdata changes, while others require remodelling. Forinstance, duct cross sections automatically reflectdimensional changes. Duct surfaces and default fittings,on the other hand, must be remodelled to reflect changes.
To maintain continuity and integrity between graphics andproject data, the software performs quick and easyupdates. Review and edit operations make changes touserdata instantaneously, while database load functionsupdate project database records. If you choose, you canhave analysis operations update userdata by means ofremodelling.
Miscellaneous Utilities
PE-HVAC provides a suite of basic utilities that control general design filemanipulations, such as saving parameters, turning levels on and off, andsetting symbologies. There are also utilities for defining active libraries andlabeling designs. Assigning standards is another utility provided. Itessentially allows you to define and apply standards to duct userdatastructures. Also included is a utility that moves PE-HVAC design files toIntergraph’s ModelView software for photo-realistic rendering.
The software further includes a suite of engineering utilities that providesbasic dimensioning and coordinate measuring functions. Grid utilitiesretrieve grid lines and annotation from master files or reference files, as wellas define auxiliary grid systems. A variety of locks is available to controlplacement techniques. The drawing lock, for example, controls placementelevation. Numerous snap features define placement points.
19
Project Engineer HVAC Overview – April 2002________________
Reference and Project Databases
PE-HVAC makes use of two types of databases – a reference database anda project database. Reference databases, as discussed previously, comprisethe various catalogs you might use at a given time. You will recall that thisstore of information represents the potential of everything you might placein your design. You can populate reference databases at any time, eitherinside or outside the graphics environment, adding single or multiplerecords in each session. The project database, conversely, represents anextraction of things from the reference database, since it contains only theinformation you actually use. It is populated using batch processes, whichrun outside the graphics environment. You can have these processes run asbackground operations while you proceed with design work on other files.
Reports
Because graphics and userdata are linked, reports are generated as a by-product of HVAC designs. The software’s reporting functions draw fromdatabase information, so they enlist RIS utilities, which can becomplemented with DBAccess software to produce customized templatesfor a variety of formats. The software is delivered with basic templates forgenerating bills of materials and material takeoffs for each HVAC element.Reports can relate information across an entire project, individual systems,or portions of systems. You graphically identify areas to report on bysimply drawing fences.
Conversion from 3-D to 2-D
PE-HVAC makes it easy to generate production drawings from 3-D models.An extract drawing command projects a 2-D image of modelled designs atspecified elevations. Additionally, it converts 3-D PE-HVAC elements to2-D symbols that are consistent with industry conventions. These symbolscan be customized as necessary to suit unique requirements. Further, thesoftware changes the symbology for ducts that are routed under other ductsto clearly delineate the difference. Flex ducts are routed as single-line arcs,though you may pattern them according to your choosing. A cleanup utilityallows you to clean up overlaps that are not properly projected when routingis performed after drawing extraction takes place.
Annotation
PE-HVAC provides a flexible environment for annotatingdesigns. You can label elements within the graphicsenvironment as you create them or use editing functions tolabel them after layout. In addition to choosing when and howyou will label, you can also define the contents of labels. You
20
Project Engineer HVAC Overview________________ can select solely from userdata or supplement with additionaldetails. The software also lets you create template cells foreach of the various elements in a design. Further, you candefine the location of labels within designs, as well as specifyleader display attributes.
Drawing Notes
PE-HVAC further provides various methods and styles for placing notes,change indicators, and various symbols, such as targets and north arrows.You can easily customize these features to meet unique specifications. Thesoftware defines rectangular and orthogonal areas for enclosing notes,automatically attaching symbols for detail and sheet numbers. Notes withleader lines can be drawn, including centerlines, match lines, and breaklines. You can place text in a layout to identify areas and equipment.Target symbols can be added to indicate work points and reference points.Addenda and bulletin notes can be displayed within clouds. And finally,drawing scales and north arrows can be designated.
Part of an Integrated Suite
In addition to PE-HVAC, Intergraph offers a sophisticated architecturaldesign application, Project Architect. These applications share a commondatabase of information that can be seamlessly accessed. It is important tonote that while each of these disciplines can reference graphics informationamong these applications, they can also reference attribute data. Yetanother benefit of this integration is the parallel communication of designdata across a multidisciplinary workflow. Since files are not copied, butreferenced, shared information is accurate up to the minute.
