EPA’s Energy Performance Rating System May 13, 2008

U.S. EPA’s ENERGY STAR ® The U.S. Environmental Protection Agency (EPA) can help you with buildings and plants to: Reduce energy waste Reduce GHG emissions Protect the environment Be a Leader – Change Our Environment for the Better

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 – The First Step to Energy Savings in Buildings  Benchmarking through ENERGY STAR allows you to: Compare one building against a national sample of similar buildings Compare all of your buildings of a similar type to each other Set priorities for use of limited staff time and/or investment capital

Portfolio Manager – Helping You Track Your Performance  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 scale Track changes in energy use over time in single buildings, groups of buildings, or entire portfolios Track cost savings and CO 2 emissions Apply for ENERGY STAR recognition Track water usage 

Offices K-12 Schools Hotels Ratable Space Types Supermarkets Hospitals Med. Office Bldgs. Others include: Warehouse, Residence Halls, Courthouses, Financial Centers, Retail, Wastewater Treatment Plants

1 Worst PerformersBest Performers Number of Buildings Top performing buildings use 3 to 4 times less energy per ft 2 than the worst performers. Newer buildings are equally represented across all quartiles. Based on a sample of 4,000 buildings nationwide 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 EPA Performance Rating & Energy Intensity (kBtu/ft 2 -year) Energy Performance Gap

Before You Start Collect Required Information Building Identifiers Name, street address, zip code for weather normalization Energy Use Bldg specific invoice information from all purchased energy At least 11 consecutive months for each source Space Type Data Square footage, hours of operation, number of students, # of PC’s, Must Meet Codes and have good IAQ ASHRAE 62, 90.1

Use the Rating to: Establish portfolio baseline, set goals, measure and track performance over time Verify gains from upgrade efforts Require specific rating gains from service providers in select building types such as office or warehouse

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 ADJUST 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

Portfolio Manager Features Master account feature View (and Reporting) Options Statement of Energy Performance Percent energy reduction Water tracking Automated benchmarking Multi-Facility Meter Update

Tracking Campaigns: Master Accounts Objective: Allows colleges and universities to track progress of campaigns, for example: University systems can track individual campuses Energy saving competitions among residence halls or other buildings Process: Institution creates a Master Account Master Account appears in a public registry Individual users can share facilities with Master Account Master Account holder can view progress for all facilities that have been shared

View (and Reporting) Options The “My Portfolio” page uses views to display summarized data A view is a set of columns that display various data in a table Portfolio Manager provides the ability for a user to create their own view by selecting the columns (up to seven at a time) to display on the My Portfolio page It also enables the user to select the number of facilities that can display on the My Portfolio page (e.g., 25, 50). There are over 30 different data columns that can be selected Any view can be set as the default view and these views can be downloaded into a Microsoft Excel spreadsheet for further analysis

Statement of Energy Performance Objective: The SEP can be generated for purposes other than applying for the ENERGY STAR Label LEED-EB certification process Real estate transactions Maintaining a Facility Summary Report 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

Percent Energy Reduction Objective: Provide a metric to show a percent change in energy use over time Creates tracking capability for all space types Process: For non-ratable spaces the tool compares weather normalized source energy use between two periods and adjusts for any changes in square footage For ENERGY STAR ratable space types, the tool compares energy use between two periods adjusting for changes in weather and business activity

Water Tracking Objective: Allow users to track water use in Portfolio Manager Continued emphasis on tracking all utilities Lay groundwork for understanding the relationships between water and energy use Process: User can select “Add Water Meter” for any facility User can identify water meters as indoor, outdoor, or wastewater Tool displays water use totals for any 12 month period User can compare two different periods and track over time Upcoming Enhancement: percent change between two time periods will be displayed

Multi-Facility Meter Update Objective: Provide the ability to easily update meter data for a large number of facilities, greatly increasing the efficiency for meter updates Process: Users select the facilities in their portfolio (maximum of 250 per download). A Microsoft Excel spreadsheet lists each facility and the specified number of meter data entries (billing cycles) Once meter data is entered and saved, the spreadsheet is uploaded. Users can review and edit the data before uploading it to Portfolio Manager This feature is used to update meter data; it will not overwrite or replace meter data that already exists in Portfolio Manager

Automated Benchmarking Allows utilities and energy info service providers to: Securely exchange building and utility data with the EPA ENERGY STAR program Leverage the ENERGY STAR rating within their own systems Reduce the burden on energy end users of benchmarking their energy performance
