1 Improving Building Energy Efficiency: Adoption, Enforcement, and Compliance with Energy Standards and Codes Minjoo Lee ASHRAE Summer Fellow Bucknell University 12 August 4, 2011

2 Commercial Building Facts 68% of nations electricity 39% of total energy consumption 12% of water usage 38% of CO2 emission /

3 Why the focus on building energy efficiency? Lower energy bills for consumers Creates jobs Better working environment Raises the value of property Less GHG Limited supply of natural gas and coal When it comes to saving money and growing our economy, energy efficiency isn't just low hanging fruit; it's fruit laying on the ground. - Secretary of Energy, Steven Chu

4 Most Cost-Effective Method of Achieving Energy Efficiency: Standards & Codes Adopting, enforcing, and complying with existing standards and codes is the cheapest and the most effective way to make buildings energy efficient Adoption Enforcement Compliance

5 Standards & Codes Standard: Voluntary until adopted into a code More general and has more purposes in terms of use ASHRAE develops standards, not codes Code: Only one purpose – to be adopted into law ICC develops codes

6 Who is involved?

7 History of Energy Policies American Recovery and Reinvestment Act (ARRA), 2009 Energy Policy Act of 2005 Energy Policy Act of 1992 National Energy Conservation Policy Act (NECPA), 1978

8 Energy Code Status Within the U.S.

9 Main Concerns in Achieving Energy Efficiency Out-of-Date Data Commercial Building Energy Consumption Survey (CBECS) Conducted by the Energy Information Administration (EIA) of DOE since 1979 Currently using 2003 data because 2007 CBECS was invalid; not enough funds for 2011 CBECS Building Rating Systems Cause confusion in the market US Green Building Council: Leadership in Energy and Environment Development (LEED) Green Building Initiative: Green Globes certification lt.aspx

10 Main Concerns… Training for Code Officials Different between jurisdictions Inconsistent structure of training Upfront Cost Misconception of high cost; not thinking about payback Vancouver example: moderately high-performance building was 9% less expensive and consumed less energy No Statewide Energy Policy Up to state and local jurisdictions to adopt codes No urgency in energy savings

11 Recommendations

12 1. Target Commercial Buildings 2. Up-to-Date Data Collection Best to first look at short term goals rather than tackling both residential and commercial Easier because it is more leveraged and businesses can afford to be involved More professionals involved in the projects, more willing to follow codes Commercial Building Energy Consumption Survey (CBECS): o Need new data to use as reference for current technology o Energy Star, ASHRAE, and other organizations use CBECS to set benchmarks o Need to continue CBECS; more funding needed o Relatively inexpensive: $4 million

13 3. Focus on Standards of Certain Building Subsystems Important to have standards that address all components BUT overwhelming to fix every element of building at once => focus on certain standards, take smaller steps Standards focused on lighting, heating and cooling systems Lighting: 25%-50% Heating: 33%-50% Increase daylight o Daylighting can help energy savings by 30%-80% annually Better insulation in walls, ceilings, basement, and windows minimize heat loss

14 4. Support a National Building Code Hard to establish building policies at federal level because regulated locally Should be flexible enough to match different climates; advancement in technology should make it easier today Should not mandate methods but set minimum benchmark, outcome is more important Waxman-Markey Bill, 2009 o Included national building energy code o Perceived as overly ambitious: 50% reduction in energy consumption by 2014 Building should compare its performance to its own past performance

15 5. More Energy Disclosure Laws Common in Europe and Australia Similar method to labeling appliances with Energy Star Adopted in Washington, D.C., Austin, Texas, New York City, San Francisco, and the state of Washington – quickly gaining popularity Has created jobs in sustainability services firms Stimulate states to adopt energy codes Benefits: 1.More occupants, higher lease, higher sales 2.Competition in the marketplace 3.Influence building owners to retrofit their building to have higher ratings compared to competitors

16 6. Revise Current Programs PACE: Property Assessed Clean Energy Special type of property loan for retrofitting – financing energy efficiency and renewable energy projects; stays with property, not the owner Popular idea in the beginning Federal government provided over $150 million in grant money to help originally Was intended for residential and commercial Lack of support from Fannie Mae and Freddie Mac discouraged many states Currently 4 active PACE programs and 9 programs in the design process Need to be revised to only address commercial buildings

17 7. Training for Code Officials Training needs to be more consistent and similar between jurisdictions Overall structure of the training should be similar Becomes easier for jurisdictions to figure out what training methods work or what methods do not work when structure of training is similar Communication between jurisdictions can become more widespread in search of better ways to make changes in the training In-class education by experienced code official, engineer, and architect On-site mentorship Written exams Annual retraining with workshops provided by organizations like ASHRAE and ICC

18 In Summary… Following energy standards and codes is the most cost-effective way to achieve high energy efficiency of buildings Better for economy, create jobs To continue having comfortable lifestyle, changes need to be made to reduce energy consumption Quicker depletion of fossil fuel – limited supply Preemptive
