Introduction to Commercial Building Energy Efficiency through EPA’s ENERGY STAR program

1. Introduction to Commercial Building Energy Efficiency through EPA’s ENERGY STAR program Week 4: Benchmarking Buildings and Prioritizing Improvements within a Portfolio of Buildings

2. Outline • Class Objectives • ENERGY STAR for Commercial Buildings— Benchmarking Buildings and Prioritizing Improvements within a Portfolio of Buildings • ENERGY STAR Energy Management Tools • Benchmarking with Portfolio Manager • Live Demonstration • Benchmarking a Portfolio of Buildings • Building Upgrade Manual • Getting Started on Your Commercial Project Building

3. Class Objectives After today’s lecture, you will be able to: • Benchmark the energy use of a building using monthly energy bills and other required building data • Analyze and explain the benchmarking results to others in the class (and possibly the building owner/manager) using data from Portfolio Manager • Generate a Statement of Energy Performance and a Data Checklist from Portfolio Manager for a building and review the data to confirm its accuracy • Explain how to identify priority projects with a portfolio of buildings

4. ENERGY STAR Energy Management Tools

5. ENERGY STAR Resources Guidelines for Energy Management • STEP 1: Commit to Continuous Improvement • STEP 2: Assess Performance • STEP 3: Set Goals • STEP 4: Create Action Plan • STEP 5: Implement Action Plan • STEP 6: Evaluate Progress • STEP 7: Recognize Achievements http://www.energystar.gov/buildings

6. ENERGY STAR Resources • Building Upgrade Manual Plan and implement profitable energy saving building upgrades utilizing five stages: • Retrocommissioning • Lighting upgrade • Load reductions • Air distribution systems upgrade • HVAC upgrade • Cash Flow Opportunity (CFO) Calculator Helps answer three critical questions about efficiency projects: • How much new energy efficiency equipment can be purchased from the anticipated savings? • Should this equipment purchase be financed now or is it better to wait and use cash from a future budget? • Is money being lost by waiting for a lower interest rate?

7. Benchmarking with Portfolio Manager

8. Benchmarking 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

9. Portfolio Manager Benchmark the energy use of all buildings –receive an energy use intensity (EUI). Many buildings, including office buildings can receive energy performance ratings on a 1-100 scale. Track changes in energy and water use over time in single buildings, groups of buildings, or entire portfolios. Track and report cost savings and CO2 emissions. Apply for the ENERGY STAR. www.energystar.gov/benchmark Benchmarking

10. Houses of Worship K-12 Schools Office Buildings Dormitories Bank/Financial Institutions Medical Offices Hospitals Retail Stores Warehouses Hotels Wastewater Treatment Plants Data Centers Supermarkets Courthouses ENERGY STAR Score Eligible Building Types

11. Examples of Non-Ratable Space Types • Police Stations • Fire Stations • Assisted Living Facilities • Convention Centers • Laboratories • Libraries • Malls • Movie Theatres • Restaurants • Stadiums and Arenas

12. Portfolio ManagerFour Simple Steps 1. Create/edit a Portfolio Manager account 2. Add/edit a property 3. Add/edit a space 4. Add/edit energy meters

13. Required Information for Benchmarking in Portfolio Manager • Building Identifiers • Name, street address, zip code for weather normalization • Space Type Data (office example) • Square footage, hours of operation, Number of workers on main shift , # of PC’s, Percent of gross floor area that is air conditioned, heated • Energy Use • Bldg specific invoice information from all purchased energy. Begin with at least 11 consecutive months for each source and update with monthly usage data.

14. Energy Use: How to Read a Utility Bill

15. Assess Performance for Smart Energy Management Verify gains from upgrade efforts Require specific rating gains from service providers in select building types such as office or warehouse

16. Identify Best Opportunities for Energy Efficiency Improvements Identify under-performing buildings to target for energy efficiency improvements Establish baselines to set goals and measure progress

17. Track Progress Over Time Set a custom baseline and monitor energy efficiency improvements before, during, and after an upgrade project View percent improvement in weather-normalized energy use intensity Track reductions in greenhouse gas emissions Monitor energy and water costs

18. Document Savings Results • Provide transparency and accountability to help demonstrate strategic use of capital improvement funding • Quickly and accurately demonstrate savings for an individual building or entire portfolio: • Energy use • GHG emissions • Water use • Energy costs • Download performance metrics from Portfolio Manager into Excel • Generate a Statement of Energy Performance (SEP) for each building, summarizing important performance indicators, including energy intensity and CO2 emissions • Generate an Energy Performance Report showing reductions in key indicators over a user-specified time period Visitwww.energystar.gov/benchmarkto get started

38. Downloading Import Templates (1) Click the Import Facility Data link, and on the next screen, right click on the desired template link. Select “Save Target As,” and follow the instructions. (1)

39. Import Template Overview Be sure to populate the User, Facilities, Primary Space, and Energy Use tabs with the required data. Additional tabs are included for instructions and secondary space types (if any). NOTE: The following is an example of how to use the import template. While this example shows you how to import data for an office space (general or courthouse) into the Portfolio Manager, the process is similar for other space types. In the User tab, enter your login name, indicate user contact information, and respond to optional questions for EPA tracking purposes. Use the Facilities, Space, Energy Use, and Water Use tabs to fill in the required data. For additional space types, fill in fields for Parking Space,Data Center Space, and Swimming Pool (if available). Read the Instructions and Import Tips tabs for information on the import process and data requirements. To import the data into Portfolio Manager, e-mail the completed template to buildings@energystar.gov

40. Populating and Importing Data from Import Template Populate data fields with basic facility information (Facilities tab) Space Use information (Office Space tab)

41. Populating and Importing Data from Import Template EnergyUse data needed in Portfolio Manager (Energy Use tab)

42. How to Access Portfolio Manager • Single Building Manual Entry • Enter building and energy consumption information into Portfolio Manager. • Bulk Data Upload • Upload large sets of building data in Portfolio Manager using an Excel template. • Automated Benchmarking Services • Use Service and Product Provider to have the rating automatically integrated into your energy information and bill handling system • Utility-based Automated Benchmarking • Option 1: Provide utility data • Option 2: Provide automated benchmarking services

43. Rating Interpretation MAINTAIN 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. ADJUST 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. INVEST 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. 1 50 75 100 ENERGY PERFORMANCE RATING Once an energy performance baseline rating is established, the next steps are to set improvement goals and create an action plan.
