David Eldridge of Grumman / Butkus Associates present the ASHRAE Building Energy Quotient Labeling Program at the 2012 Chicago Energy Modeling Conference.

1. Presentation to:
Chicago Energy Modeling Conference
February 14, 2012

2. Why Building Energy Labeling?

4. Information for Consumers to Allow
Educated Choices is Not New
Restaurant Sanitation Ratings
Car Fuel
Economy
Estimates
Nutrition Facts Label

5. Building Energy Labels. . .
Promote the value of energy efficiency
in the marketplace
Differentiate buildings with good
performance for potential
tenants/buyers
Enhance building owner’s ability to
identify energy efficiency
measures to help improve
operations

6. Building Energy Labels. . .
Provide clear communication of energy
performance to the public
Contribute to building performance
databases – potential and actual
energy use
Highlight the drive toward
Net Zero Energy Buildings

7. Current “Building Label” Efforts in the US:
– Energy Star
– DOE
– LEED Certifications
– Green Globes
– BOMA 360
All of these Programs are Voluntary

8. Mandatory labeling requirements:
– European Union
– Canada
– California
– Washington, DC

9. Why Should Professionals & Owners Care?
• Professionals
– An additional service for consulting firms and others
– Required certifications demonstrate competency
• Owners
– Benchmarking
– Recognition for participation can enhance a
company’s image and reputation
– Economic benefit of improving design and operation
– Potential for mandatory labeling and related
requirements in future

11. Why ASHRAE?
• Over 100 years of experience in the
building sciences
• 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
• Proven history working with DOE and
other professional organizations

12. What is bEQ?
• A voluntary certification program
• A technical method that draws on
successful features of other US and
European building certifications
• Complements other green building
rating systems and energy certification
programs
• Can be a tool to stimulate adoption of
high performance building techniques

13. Developing bEQ
• bEQ Development Committee
– International team of experts
– Representatives from the Energy Star and EU
labeling programs
– Building energy modeling experts
– Representatives from utilities, government,
and advocacy community
• Technically sound and widely applicable
program
• Validate and enhance the program using
ASHRAE’s broad technical resource network

14. Types of Ratings
In Operation Rating (Operational)
• Actual 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

15. Types of Ratings
In Operation Rating (Operational)
• Building characteristics
• Design goals (if applicable)
• Other certifications
• Conditioned area, floors, age, contact
• Building HVAC and envelope systems
• Energy calculations
• Normalized EUI compared to median value
• Raw utility usage

16. Types of Ratings
In Operation Rating (Operational)
• IEQ certification
• Thermal comfort – temperature and
humidity, air velocity, temperature
asymmetry
• Lighting quality – horizontal / vertical fc,
ballast types, daylight
• Indoor air quality –OA calculations from
design / measured rates
• Surveys – occupant survey from CBE
• Measurements to back up evaluation!

17. Types of Ratings
In Operation Rating (Operational)
Energy Use (kWh/ft2-yr)*
• Energy end-use breakdown
• Metered vs calculated Supply Fans
Exhaust/Return
Fans
16.2% 3.2%
Plug Loads
28.5%
Energy Use
End Use (kWh/ft2-yr)
Supply Fans 3.18 Cooling
Exhaust/Return Fans 0.62 Equipment
Cooling Equipment 1.62 8.2%
Lighting 4.22 Domestic Hot

Domestic Hot Water 0.09 Electric Heat
17.0% Lighting
Plug Loads 5.60
21.5%
Total Energy Entered 19.66
Condenser
Water Pumping
5.1%

18. Types of Ratings
In Operation Rating (Operational)
• Listing of possible energy efficiency
measures (EEMs) for the building
• ASHRAE Level 1 effort for rigor of
evaluation – focus on energy
savings, not necessarily cost savings
• Source energy comparison

19. Types of Ratings
In Operation Rating (Operational)
• Building characteristics
• Energy calculations
• IEQ certification
• Thermal comfort
• Lighting quality
• Indoor air quality
• Surveys
• Measurements
• Energy end-use breakdown

20. 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

21. Features of bEQ Program:
• Potential side-by-side comparison of As
Designed (asset) and In Operation (operational)
Ratings
• Building assessment identifies both
peak demand reduction and energy
management opportunities
• Recognizes energy use from on-site renewables
• Includes measurement-based Indoor
Environmental Quality (IEQ) indicators to assure
levels of service are maintained

22. Relationship to Other Programs
• Europe
– Directive 2002/91/EC on the energy performance of
buildings
– Standard EN 15217 Energy performance of
buildings—methods for expressing energy
performance and for energy certification of buildings
(2007)
– Explicit effort to learn from EU experience
Austria England & Wales Greece Italy

23. bEQ and Existing ―Green‖ Programs
like LEED or GreenGlobes?
• Focuses on a building’s energy use while
also ensuring adequate building IEQ
• Helps identify opportunities for
improving energy performance

24. bEQ and EPA’s Energy Star Program?
• Greater differentiation for high performing
buildings
• Emphasis on top performers and net zero
energy operation.
• Required site visit to validate information
and IEQ
