2. Building Energy Quotient™ASHRAE’s Building Energy Labeling Program Providing Valuable Information to Building Owners and Operations Staff March 2010

3. Building Energy Labels Provide. . . • Information on the potential and measured energy use of buildings • Feedback to building owners and operators on how their building is performing • Insight into the value and potential long-term energy costs • Differentiation in the marketplace

5. Is a Building Energy Disclosure Program a Cost Effective Means for Reducing Energy Use?

6. Why ASHRAE? • Over 100 years of experience in the building sciences and technology • Strong technical expertise across all aspects of building design and operation • Historic focus on developing consensus-based, non-commercial documents • Respect and credibility within the building community

7. Why Now? Potential utilization outside of North America for areas without existing labeling programs Mandatory labeling requirements already in place: • European Union • California • Washington, DC • Austin, TX Building owners need a technically sound label that can serve as a consistent model for such mandatory programs.

8. Developing the Program • Technically sound and widely applicable program • Committee with international team of experts • Members familiar with the Energy Star and EU labeling programs • Building energy modeling experts • Representatives from utilities, government, and advocacy community. • Validate and enhance the program using ASHRAE’s broad technical resource network

9. What types of Ratings? In Operation Rating (operational) • Measured energy use of a building • Based on combination of structure and features of the building and how it is operated • Applicable for existing buildings • Applicable for new buildings after 12-18 months of operation. • 2010 pilot is for In Operation rating only.

10. What types of Ratings? As Designed Rating (asset) • Assessment of the building based on design components: mechanical, envelope, orientation, and lighting. • Based on results of a building energy model • Applicable to both new and existing buildings • Can be used to make choices between potential building designs • As Designed rating pilot will follow later in 2010

11. How is bEQ Program Different from “Green” Programs like LEED or GreenGlobes? • Focuses on a building’s energy use while ensuring adequate building IEQ • Greater concentration on understanding energy use and identifying opportunities for improvement • Could be used to improve/verify energy component of green building rating systems

12. How is bEQ Different from Energy Star? • Greater differentiation for high performing buildings with emphasis on top performers and net zero energy operation. • Required site visit to validate information and IEQ • Able to label building types outside of Energy Star • Measured IEQ performance • Peak demand data – load factor • Expanded information provided for how to improve energy performance

13. These Buildings are “Green”How Efficiently Do They Use Energy? This Building has a Good Energy Quotient

14. Providing Relevant Information The Label: • Most visible component of the program • Simple to understand – targets general public at the state and local level • Suitable for display in building lobbies and marketing materials • Satisfies public disclosure requirements at the state and local level

15. Providing Relevant Information The Certificate: • Technical information explains the rating score • Information useful to building owners, tenants, utilities, and operations and maintenance personnel Additional Documentation: • Background technical information • Useful for engineers, architects, and technically savvy building owners • Useful for determining current state of the building and opportunities for improving its energy use

16. Why Should Owners be Interested?Manage portfolios and identify investment opportunities Existing Building Portfolios (In Operation Rating): • What can the staff managing this building share with my other building managers? • Am I getting a premium for this building? • Is there a particular reason this building is performing better? • This building could use improvement. • What investments could improve energy use? • Does the O&M team need additional training? • Can re-commissioning or retro-commissioning address poor performance?

17. Why Should Owners be Interested?Make educated decisions on new building design Design Options for a New Building (As Designed Rating): • Which design will be most marketable? • What can I expect in future energy costs? • Does the design meet my initial energy use expectations? • What will I need to do to assure the building performs to its potential?

18. Benefits for Building Owners • Side-by-side comparison of As Designed (asset) and In Operation (operational) Ratings • Measurement-based Indoor Environmental Quality (IEQ) indicators to assure levels of service are maintained • List of operational features including commissioning activities, energy efficiency improvements • Provides information on how the building is using energy and how performance can be improved • Differentiate building from peers to attract tenants or potential buyers

19. Supporting the Program • Instruction Manuals • Technical Guidance • Educational Programs • Advocacy Materials • User-friendly Internet-based Interface • Energy Modeling Certification Program • Energy Assessor Certification Program

20. Availability and Cost • Pilot for In Operationrating begins now • Pilot for As Designed rating begins mid 2010 • Widespread launch anticipated in early 2011 • Annual renewal for operational ratings • Cost to obtain label is not yet determined • Aware of limited budgets

21. About the Pilot Participation of Prominent Building Owners/Developers Participants:

22. Pilot Program Desired Outcomes • Feedback on program logistics including: Forms, Costs, Marketability, Training • Encourage pilot participants to be ambassadors for widespread use of bEQ • Provide in-the-field results to continue interest in the program • Confirm customer acceptability

23. Pilot Program How it works • Assessor Pilot Procedures • Walk-through procedures and checklist • Definitions • Workbook form instructions • Assessor Workbook • Building Characteristics • Energy Calculations • IEQ Certification • System Energy Breakdown

24. Assessor Pilot Procedures Walk-through Procedures and Checklist • Overall process for the assessment • Contact Information • Checklist to verify that all forms have been completed
