Fuel Efficiency
MPG
Is 60 MPG high or low for an automobile?
Statement of Energy Performance
EPA Rating
Is 80 kBtu/SF/YR high or low for a building?
Need for a Rating System for Buildings
Benchmarking Allows Comparison With Similar Existing Buildings
• Compares all of your buildings to similar buildings nationwide
• Allows the setting of priorities to maximize use of staff time and/or investment capital
=
The EPA Energy Performance Rating Formula
• Based on actual “whole-building” energy performance data• DOE-CBECS
• Accounts for factors that affect energy use intensityo Climateo Size (GSF)o Occupancyo Equipment

Top performing buildings use 3 to 4 times less energy per ft2 than the worst performers.
Newer buildings are equally represented across all quartiles.
Based on a sample of 4,000 buildings nationwide.

39 percent of buildings with a rating of 75 or better are less than 25 years old
42 percent of buildings with a rating between 25 and 74 are less than 25 years old
35 percent of buildings with a rating between 0 and 24 are less than 25 years old

What is Portfolio Manager ?
Free online tool where you can:• Benchmark the energy use of all of your
buildings – all will receive an energy use intensity (EUI) and some will receive ratings on a 1-100 scale
• Track changes in energy use over time in single buildings, groups of buildings, or entire portfolios
• Track cost savings and CO2 emissions
• Apply for ENERGY STAR recognition
• Track water usage

Summary Report
ENERGY PERFORMANCE RATING
Facilities in this range may reap significant savings from concentration on simple, low-cost measures, such as improved operations and maintenance practices. Equipment upgrades could yield additional savings.
MAINTAIN
INVEST
These top performing facilities offer examples of best practices as well as opportunities to gain recognition. Continue to improve and maintain superior performance by focusing on operations and maintenance.
Facilities in this range offer the greatest opportunity for financial and environmental improvement. Investing in new equipment and enhancing operational practices may have the greatest impact on your bottom line.

Once you have established an energy performance baseline rating, you are ready to set improvement goals and create an action plan. The guide below can help you interpret the ratings and determine appropriate next steps.
Rating Interpretation
Using Portfolio Manager for LEED-EB
• The SEP can be generated for purposes such as LEED-EB certification process
• What is used for the LEED-EB process:• User selects time period of performance• Tool generates 1 page summary with energy use,
cost, and emissions figures• Summary also included as second page when full
SEP is generated to apply for the ENERGY STAR
