Building energy quotient ashrae s building energy labeling program l.jpg

Building Energy Quotient™ASHRAE’s Building Energy Labeling Program

Providing Valuable Information to Building Owners and Operations Staff

March 2010


Building energy labels provide l.jpg
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

Why ashrae l.jpg
Why ASHRAE? Means for Reducing Energy Use?

  • 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 l.jpg
Why Now? Means for Reducing Energy Use?

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.


Developing the program l.jpg
Developing the Program Means for Reducing Energy Use?

  • 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 l.jpg
What types of Ratings? Means for Reducing Energy Use?

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.


What types of ratings10 l.jpg
What types of Ratings? Means for Reducing Energy Use?

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


How is beq program different from green programs like leed or greenglobes l.jpg
How is Means for Reducing Energy Use?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 l.jpg
How is Means for Reducing Energy Use?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 green how efficiently do they use energy l.jpg
These Buildings are “ Means for Reducing Energy Use?Green”How Efficiently Do They Use Energy?

This Building has a Good Energy Quotient


Providing relevant information l.jpg
Providing Relevant Information Means for Reducing Energy Use?

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 information15 l.jpg
Providing Relevant Information Means for Reducing Energy Use?

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 l.jpg
Why Should Owners be Interested? Means for Reducing Energy Use?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 l.jpg
Why Should Owners be Interested? Means for Reducing Energy Use?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 l.jpg
Benefits for Building Owners Means for Reducing Energy Use?

  • 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 l.jpg
Supporting the Program Means for Reducing Energy Use?

  • Instruction Manuals

  • Technical Guidance

  • Educational Programs

  • Advocacy Materials

  • User-friendly Internet-based Interface
