Providing Valuable Information to Building
Owners and Operations Staff
March 2010
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
Informing Consumers to Allow Educated Choices is Not New

Is a Building Energy Disclosure Program a Cost Effective Means for
Reducing Energy Use?
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
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
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
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.
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
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
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
These Buildings are “GreenGreen”How Efficiently Do They Use Energy?
This Building has a GoodGood Energy Quotient
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
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
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?
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?
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
Supporting the Program
• Instruction Manuals• Technical Guidance• Educational Programs• Advocacy Materials• User-friendly Internet-based Interface• Energy Modeling Certification Program• Energy Assessor Certification Program
Availability and Cost
• Pilot for In OperationIn Operation rating begins now• Pilot for As DesignedAs 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
About the Pilot
Participants:
Participation of Prominent Building Owners/Developers
