Building Energy Codes Update NGA Energy Working Group April 26, 2011 \ The Internet David Conover Senior Technical Advisor Building Energy Codes Program david.conover@pnl.gov
Purpose and Expected Outcome Purpose: To provide states with an update on information related to DOE Building Energy Code Program activities that support the adoption of and compliance with building energy codes. Expected Outcome: States are more aware of free resources available from BECP to assist them in their building energy code activities. 2
Legislative Requirements to DOE Support the upgrading of the IECC and Standard 90.1 model building energy codes (ECPA 307) Determine whether the upgraded model codes will improve energy efficiency in buildings (ECPA 304) Provide financial and technical assistance to States to upgrade, implement, and enforce State energy codes (ECPA 304) \ 3

Support Voluntary Building Energy Codes Commercial and multi-family high rise Standard 90.1 Residential low-rise International Energy Conservation Code (IECC) Periodic review of IECC and Standard 90.1, based on ongoing research Recommend amendments Seek adoption of all technologically feasible and economically justified energy efficiency measures Participate in industry process for review and modification of model codes Participation in other codes and standards (IgCC, IRC, ASHRAE 189.1, 189.2, etc.) 6
ASHRAE 90.1 Update SSPC 90.1 Accomplishments Toward ASHRAE s 30% Goal Addenda processed for and contained in the 2010 Standard result in savings on the order of 30% SSPC 90.1 has adopted a goal of achieving 50% savings over 90.1-04 in 90.1-13 BECP currently working on a 50% package that if adopted would achieve the desired 50% goal 7
Model Energy Code Update Residential low-rise model code goal 2012 IECC: 30% more energy efficient than 2006 IECC. BECP currently working on a 50% package for residential (Chapter 4) and would adapt the 50% package for 90.1 for submission to the IECC. Proposed changes to the IECC due January 3, 2013. 8
Stretch/Green Codes ASHRAE 189.1-09 published and working on revisions to that document for 2013 edition. ASHRAE 189.2P out now for advisory public review and comment and assisting with development of this standard. Participation in the development of the ICC IgCC hearings May 2011 and final vote on 2012 edition October 2011. Participation in the updating of ICC/NAHB 700. 9
Post Development Adopt what is developed. Implement what is adopted. Enforce what is adopted. Verify compliance is achieved. Enhance as needed to increase compliance. 10

Challenges Code Development Reaching consensus on the details. Code Adoption Avoiding attempts to weaken or rollback code. Encouraging automatic update provisions for states. Code Compliance Learning to design using new standards and techniques. Implementing new requirements at the jobsite. Providing staff and resources to plan, review, and inspect.

Annual Energy Codes Conference Energy Codes 2011 - July 25-29 in Salt Lake City Training sessions provide opportunity to learn and network face-to-face. Featured exciting building tours, offered participants hands-on opportunity. The cracker barrel facilitated small, focused discussions covering a variety of topics (2009) Keynote speaker Mark LaLiberte shared his passion for uniting the industry to build durable, energy-efficient, healthy, and sustainable homes. Building tour participants visited the Daybreak Cohousing community, which offers numerous green features and a unique approach to urban living. The First & Main building, part of the Energy Codes 2009 building tours, is expected to receive a LEED Platinum rating, even with all of those windows!
Compliance Assistance BECP guidelines and tools to use in compliance with codes, which: foster uniformity and objectivity in measuring compliance rates eliminate need for each state to develop their own procedures and tools measuring building energy provide tools that states can adapt for their own preferred use on-line store and score collect additional data and support related activities over 10 states using these materials 26
Checklists
Score and Store Online web application that stores building evaluation data collected as part of a formal state compliance evaluation effort. The application scores the data (both individual building and state scores), and allows analysis of data collected across states.
Score and Store
EnergyCodeCheck Online software platform used to simulate the energy and cost savings impacts of code changes based on the same methodology currently used by the BECP R&D team for generating code change proposals. The tool will use EnergyPlus simulations to allow states to compare code impacts, such as the expected energy savings if they adopt a new code, and to evaluate impacts of state amendments. Available: August 2011
EnergyCodeCheck
State Leadership Provide a strong energy code as a foundation for the state s building sector. Set an example through statefunded buildings. Provide guidance on enforcement strategies. Provide support to building professionals and code officials. 33
Use Our Resources DOE s Building Energy Codes Program is an information resource on national model energy codes. We work with other government agencies, state and local jurisdictions, national code organizations, and industry to promote stronger building energy codes and help states adopt, implement, and enforce those codes.
