ENERGY STAR
for Commercial Buildings
What is ENERGY STAR for Buildings?
• EPA voluntary climate protection
partnership with energy users and
service and product providers
• Helps organizations measure, track,
and improve energy performance
• Helps organizations save energy and
money and protect the environment
• Brand recognition: >90% of Americans
4
ENERGY STAR Buildings Milestones
In the past 15 years:
• 415,000 buildingsmeasured energy performance
• Nearly 6,000 organizationsjoined as partners
• 25,000 buildings earned the ENERGY STAR Certification across 50 states
5
Benchmarking Building Energy Performance with ENERGY STAR
Is 60 MPG high or low…for this automobile?
Is 90 kBtu/SF/YR high or low…for this building?
Fuel Efficiency: MPG

• Management Tool – Helps business and organizations by offering a platform to:
– Assess whole building energy and water consumption– Track changes in energy, water, greenhouse gas emissions, and cost over time– Track green power purchase– Share/report data with others– Create custom reports– Apply for ENERGY STAR certification
• Metrics Calculator – Provides key performance metrics to integrate into a strategic management plan
– Energy consumption (source, site, weather normalized)– Water consumption (indoor, outdoor)– Greenhouse gas emissions (indirect, direct, total, avoided)– ENERGY STAR 1-to-100 score (available for many building types)
Accessible in a free, online secure platform: www.energystar.gov/benchmark

Background to Benchmarking in Portfolio Manager
• EnergyCAP automatically populates building, meter, and utility bill data
in Portfolio Manager
• To benchmark your buildings, simply activate ENERGY STAR submittals
in EnergyCAP. There is no additional fee to do this
• Set your building(s) up in EnergyCAP to submit to Portfolio Manager
(http://bit.ly/1E1zo6N)
– Property Information (go to Buildings and Meters / Building
Properties)• Name, street address, ZIP/postal code
• Floor Area
• Function(s) (space types)
• Include/Exclude Meters
– Property type data • Use details (ex. weekly operating hours, number of computers,
number of workers on the main shift, etc)
– Energy consumption data• Utility bills already entered into EnergyCAP
• Submit to Portfolio Manager (http://bit.ly/1bkytnd)
13
To Get Started Benchmarking in Portfolio Manager…
ENERGY STAR 1-100 Score: Eligible Property Types
• Bank branch
• Barracks
• Courthouse
• Data center
• Distribution center
• Financial office
• Hospital* (general medical & surgical)
• Hotel
• K-12 school*
• Medical office
• Multifamily housing
• Non-refrigerated warehouse
• Office*
• Refrigerated warehouse
• Residence hall/ dormitory
• Retail store
• Senior care community
• Supermarket/grocery store*
• Wastewater treatment plant
• Wholesale club/supercenter
• Worship facility
* These property types are also eligible to receive an ENERGY STAR score in Canada
ENERGY STAR Score: Inputs Needed
• K-12 School
– Gross Floor Area
– Number of Personal Computers
– Number of Walk-in Refrigerators
– Whether or not the School is Open
on Weekends
– Whether or not there is Energy
Used for Cooking
– Whether or not the school is a High
School
– Weather and Climate (using Heating
and Cooling Degree Days, retrieved
based on Zip code)
– Percent of the Building that is
Heated and Cooled
• Office
– Building Size
– Number of Personal Computers
– Number of Workers
– Hours of Operation per Week
– Weather and Climate (using Heating
and Cooling Degree Days, retrieved
based on Zip code)
– Percent of the Building that is
Heated and Cooled
Inputs for additional space types available at: http://www.energystar.gov/buildings/facility-owners-and-managers/existing-buildings/use-portfolio-manager/understand-metrics/energy-star
Default values based on floor area can be entered for these inputs during the initial benchmarking effort if accurate data is not available
ENERGY STAR Score: How It Is Calculated
• Basic Steps to Compute a Score:
1. Compute Actual Source EUI
2. Compute Predicted Source EUI
3. Compute Energy Efficiency Ratio
4. Lookup Score
ENERGY STAR 1 – 100 Score
Postal code
Whole building energy
use
Property use
details
Site energy accounts for only 33%
of embodied energy consumed at
the building site as electricity
Site energy doesn’t account for
total carbon emissions
The Score and Source Energy
17
Step 1: Compute Actual EUI
• Compute Annual Source Energy for each fuel type
– Add together all 12 months of energy
– Multiply total annual energy (in kBtu) by the source
energy conversion factor
• Add the Annual Source Energy of all fuel types
together
• Divide by the total square foot
18
Step 2: Compute Predicted Source
EUI• Predicted Source EUI is calculated based on:
– The survey data for the property’s specific type (Office, K-12 School, Hotel,
etc.)
– The property use details entered for the specific property (number of PCs,
weekly operating hours, etc.)
– The heating and cooling degree days in the property’s zip code during the
performance period
• The result is the source EUI that a median property of that type and that location
would have during the performance period
• You can find more information on the specific calculations for each property type
at: http://www.energystar.gov/buildings/facility-owners-and-managers/existing-
buildings/use-portfolio-manager/understand-metrics/energy-star
19
Step 3: Compute Energy Efficiency Ratio
• Divide the Actual Source EUI by the Predicted Source
EUI(Actual/Predicted)
• This is the energy efficiency ratio
20
Step 4: Lookup the Score• Lookup the ratio in the lookup table- each property type has a
unique lookup table
• Example K-12 Lookup Shown below
– A ratio of 0.25 gets a score of 100; it is less than 0.3710 and
greater than or equal to 0
– A ratio of 0.431 gets a score of 98; it is less than 0.4555 and
greater than or equal to 0.4212
21

100 0% 0 0.3710
99 1% 0.3710 0.4212
98 2% 0.4212 0.4555
97 3% 0.4555 0.4825
Step 5: Receive ENERGY STAR Rating
• Your ENERGY STAR rating (score) and other data are automatically
uploaded to EnergyCAP and displayed onscreen and in reports
• The rating is imported into EnergyCAP from Portfolio Manager- you’ll
need to click on the ‘Get Ratings’ button to complete the process
How to Use Sharing and Reporting Features
in Portfolio Manager• As an EnergyCAP user, you never have to login to Portfolio Manager’s
user interface unless you have to share your data under mandatory
government benchmarking legislation
• However, the user interface does have some useful tools, so next let’s
discuss what sharing features are available
How to Share Properties
• 3 Steps:
1. Confirm you are connected to the person you
want to share with on the Contacts page. “Add
Contact” to send a connection request if needed.
2. Share one or more of your properties with your
connected contacts & specify the level of access
the contacts have to view and edit your properties
3. Review shared properties on the Sharing tab

• Mandatory Disclosure – State & Local
60
Trend – Benchmarking Mandates are Gaining
Momentum Nationwide
61
Portfolio Manager in State and Local
Building Energy Policy
• All jurisdictions with benchmarking laws specify the use of ENERGY STAR Portfolio Manager
• Purpose of these laws:– Increase transparency of building performance data for a better
informed market (energy and water)
– Incentivize improvements in public and private buildings
– Grow clean energy job market
– Improve building infrastructure
– Reduce carbon footprint
– Increase electrical system reliability
• Some newer policies (Chicago; Montgomery County, MD) require licensed-professional verification of benchmarking data
62
Outlook – Energy Benchmarking and
the City Energy ProjectThe City Energy Project
• Joint project of IMT and NRDC
• Initiative to help cities craft policies and
programs to improve large-building
energy performance
• 10 pioneering cities:
Atlanta Kansas City, MO
Boston Los Angeles
Chicago Orlando
Denver Philadelphia
Houston Salt Lake City63
