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

Is a Building Energy Disclosure Program a Cost Effective Means for
Reducing Energy Use?
![Page 6: ASHRAE’s Building Energy Labeling Program bEQ ACG 6 th Annual Conference on Total Building Commissioning April 15, 2010 Bruce D. Hunn Director of Strategic.](https://reader036.fdocuments.net/reader036/viewer/2022062322/56649e7a5503460f94b7a38a/html5/thumbnails/6.jpg)
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
![Page 7: ASHRAE’s Building Energy Labeling Program bEQ ACG 6 th Annual Conference on Total Building Commissioning April 15, 2010 Bruce D. Hunn Director of Strategic.](https://reader036.fdocuments.net/reader036/viewer/2022062322/56649e7a5503460f94b7a38a/html5/thumbnails/7.jpg)
Why Now?Potential utilization outside of North America
for areas without existing labeling programsMandatory labeling requirements already in place:
• European Union• California• Washington, DC• Austin, TX
![Page 8: ASHRAE’s Building Energy Labeling Program bEQ ACG 6 th Annual Conference on Total Building Commissioning April 15, 2010 Bruce D. Hunn Director of Strategic.](https://reader036.fdocuments.net/reader036/viewer/2022062322/56649e7a5503460f94b7a38a/html5/thumbnails/8.jpg)
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
![Page 9: ASHRAE’s Building Energy Labeling Program bEQ ACG 6 th Annual Conference on Total Building Commissioning April 15, 2010 Bruce D. Hunn Director of Strategic.](https://reader036.fdocuments.net/reader036/viewer/2022062322/56649e7a5503460f94b7a38a/html5/thumbnails/9.jpg)
What types of Ratings?
In Operation RatingIn 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.
![Page 10: ASHRAE’s Building Energy Labeling Program bEQ ACG 6 th Annual Conference on Total Building Commissioning April 15, 2010 Bruce D. Hunn Director of Strategic.](https://reader036.fdocuments.net/reader036/viewer/2022062322/56649e7a5503460f94b7a38a/html5/thumbnails/10.jpg)
What types of Ratings?As Designed RatingAs 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
![Page 11: ASHRAE’s Building Energy Labeling Program bEQ ACG 6 th Annual Conference on Total Building Commissioning April 15, 2010 Bruce D. Hunn Director of Strategic.](https://reader036.fdocuments.net/reader036/viewer/2022062322/56649e7a5503460f94b7a38a/html5/thumbnails/11.jpg)
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
![Page 12: ASHRAE’s Building Energy Labeling Program bEQ ACG 6 th Annual Conference on Total Building Commissioning April 15, 2010 Bruce D. Hunn Director of Strategic.](https://reader036.fdocuments.net/reader036/viewer/2022062322/56649e7a5503460f94b7a38a/html5/thumbnails/12.jpg)
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
![Page 13: ASHRAE’s Building Energy Labeling Program bEQ ACG 6 th Annual Conference on Total Building Commissioning April 15, 2010 Bruce D. Hunn Director of Strategic.](https://reader036.fdocuments.net/reader036/viewer/2022062322/56649e7a5503460f94b7a38a/html5/thumbnails/13.jpg)
These Buildings are “GreenGreen”How Efficiently Do They Use Energy?
This Building has a GoodGood Energy Quotient
![Page 14: ASHRAE’s Building Energy Labeling Program bEQ ACG 6 th Annual Conference on Total Building Commissioning April 15, 2010 Bruce D. Hunn Director of Strategic.](https://reader036.fdocuments.net/reader036/viewer/2022062322/56649e7a5503460f94b7a38a/html5/thumbnails/14.jpg)
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
![Page 15: ASHRAE’s Building Energy Labeling Program bEQ ACG 6 th Annual Conference on Total Building Commissioning April 15, 2010 Bruce D. Hunn Director of Strategic.](https://reader036.fdocuments.net/reader036/viewer/2022062322/56649e7a5503460f94b7a38a/html5/thumbnails/15.jpg)
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
![Page 16: ASHRAE’s Building Energy Labeling Program bEQ ACG 6 th Annual Conference on Total Building Commissioning April 15, 2010 Bruce D. Hunn Director of Strategic.](https://reader036.fdocuments.net/reader036/viewer/2022062322/56649e7a5503460f94b7a38a/html5/thumbnails/16.jpg)
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?
![Page 17: ASHRAE’s Building Energy Labeling Program bEQ ACG 6 th Annual Conference on Total Building Commissioning April 15, 2010 Bruce D. Hunn Director of Strategic.](https://reader036.fdocuments.net/reader036/viewer/2022062322/56649e7a5503460f94b7a38a/html5/thumbnails/17.jpg)
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?
![Page 18: ASHRAE’s Building Energy Labeling Program bEQ ACG 6 th Annual Conference on Total Building Commissioning April 15, 2010 Bruce D. Hunn Director of Strategic.](https://reader036.fdocuments.net/reader036/viewer/2022062322/56649e7a5503460f94b7a38a/html5/thumbnails/18.jpg)
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
