4 Need for a Rating System for Buildings Is 80 kbtu/sf/yr high or low for a building? Statement of Energy Performance EPA Rating Fuel Efficiency MPG Is 60 MPG high or low for Is 60 MPG high or low for an automobile?

5 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, g,groups of buildings, g, or entire portfolios Track cost savings and CO 2 emissions Apply for ENERGY STAR recognition Track water usage

6 Energy and the Lodging Industry 5th largest commercial energy consumer Spend $7.5 billion per year on energy Utility costs rose 4.5% in 2007 Lighting, space conditioning, & water heating account for 75% of energy costs

7 Lodging Environmental Impact Annual energy consumption 69 billion kwh of electricity 208 billion cubic feet of natural gas Equivalent to 53 million metric tons of CO2 per year A 10% reduction in lodging industry energy consumption would be equivalent to Reducing CO2 emissions by 5.3 million metric tons Taking almost 1 million cars off the road for 1 year Offsetting the annual electricity consumption of more than 730,000 homes

9 Benchmarking The First Step to Energy Savings in Buildings Benchmarking g through ENERGY STAR allows you to: Compare one building against a national sample of similar buildings Track changes in energy use over time in single buildings, groups of buildings, or entire portfolios Set priorities for use of limited staff time and/or investment capital

10 Energy Performance Gap Numbe er of Buildin ngs 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 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 Best Performers EPA Performance Rating & Energy Intensity (kbtu/ft 2 -year) Worst Performers

11 Energy Star Label Buildings in the top 25 percent nationwide are eligible to earn for the ENERGY STAR, provided d they meet or exceed industry standards for comfort levels.

21 Portfolio Manager Log-in Page My Portfolio Page Layout Portfolio Average Rating Portfolio Adjusted Percent Energy Reduction Views Add Facility Facility Summary Page Facility Performance Space Use Energy Meters Water Meters Energy Meters Add Meter Entries Start Date, End Date, kwh, Cost

22 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

23 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 t have been shared

24 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

25 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 t transactions ti 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 d as second page when full SEP is generated to apply for the ENERGY STAR

26 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

27 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

28 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
