Under the WBA path, Simplified Trade-off forms should be included to demonstrate the differences between the design building and a compliant building.
Forms may be submitted electronically (verify with your jurisdiction).
The Secretary shall provide technical assistance to States to implement the requirements of this section, and to improve and implement State residential and commercial building energy efficiency codes or to otherwise promote the design and construction of energy efficient buildings.
(1) The Secretary shall provide incentive funding to States to implement the requirements of this section, and to improve and implement State residential and commercial building energy efficiency codes, including increasing and verifying compliance with such codes.
(2)(A) Whenever the provisions of ASHRAE Standard 90.1–1989 (or any successor standard) regarding energy efficiency in commercial buildings are revised, the Secretary shall, not later than 12 months after the date of such revision, determine whether such revision will improve energy efficiency in commercial buildings.
(C) Paragraphs (2), (3), and (4) shall apply to any determination made under subparagraph (B).Their analysis* used the newly developed residential database in NIST's Building Industry Reporting and Design for Sustainability (BIRDS) software to measure the energy, environmental and cost performance of newly constructed homes located in 228 different cities and climates zones in the United States.Freely available from NIST, BIRDS is a combination of software tools and building databases for evaluating the costs and benefits associated with alternative building designs, technologies and codes and standards ((B)(i) If the Secretary makes an affirmative determination under subparagraph (A), each State shall, not later than 2 years after the date of the publication of such determination, certify that it has reviewed and updated the provisions of its commercial building code regarding energy efficiency in accordance with the revised standard for which such determination was made.Such certification shall include a demonstration that the provisions of such State's commercial building code regarding energy efficiency meet or exceed such revised standard. That's enough to power all the homes in Tucson, Ariz., for a year.Those sizable estimated savings were calculated by a pair of economists at the National Institute of Standards and Technology (NIST).(ii) If the Secretary makes a determination under subparagraph (A) that such revised standard will not improve energy efficiency in commercial buildings, State commercial building code provisions regarding energy efficiency shall meet or exceed ASHRAE Standard 90.1–1989, or if such standard has been revised, the last revised standard for which the Secretary has made an affirmative determination under subparagraph (A). The Secretary shall permit extensions of the deadlines for the certification requirements under subsections (a) and (b) of this section if a State can demonstrate that it has made a good faith effort to comply with such requirements and that it has made significant progress in doing so. Updated about every three years, the IECC is a model efficiency standard often incorporated into state regulations.National adoption of the 2012 IECC by states with energy codes based on older editions of the IECC would trim annual energy consumption by an average of nearly 20 percent for newly constructed houses.
