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?

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
