SEPTEMBER - OCTOBER 2013 The 2013 Standards Will Go Into Effect January 1, 2014 The Blueprint is your guide to information, training and resources for the 2013 Building Energy Efficiency Standards. The California Energy Commission has partnered with the Statewide Codes & Standards Program to provide training and resources for building officials. California s building energy code can help save energy, keep our air cleaner and offset the need to build new power plants. We understand it can be quite technical and difficult to navigate new standards, especially when time and resources are limited. The Statewide Codes & Standards Program offers free energy code training, tools and resources for building department personnel, as well as others who need to understand and meet the requirements of Title 24, Part 6. Designed to improve compliance with the state s building energy code, the program aims to Fall 2013 Classroom Trainings Offered advance the adoption and effective implementation of energy efficiency measures and building practices to lock in long- term energy savings. The program recognizes that codes and standards are one of the most effective pathways to ensuring sustained market transformation. The key to making them work well is found in the enforcement efforts of building department professionals. Program offerings are designed for counter staff, plans examiners, field inspectors and building officials. The California Statewide Codes & Standards Program is funded by California utility customers under the auspices of the California Public Utilities Commission and implemented by Pacific Gas and Electric Company, San Diego Gas and Electric, Southern California Edison and Southern California Gas, in support of the California Energy Commission.

What's New for 2013 Non- Residential CALIFORNIA ENERGY COMMISSION PAGE 3 The process to develop the 2013 Standards began with a call for ideas in winter of 2010, moved through a series of IOU sponsored stakeholder meetings throughout the state, Energy Commission staff workshops and Energy Commission hearings in 2011 through 2012 and concluded at the adoption hearing on May 23, 2012. Energy Commission staff, contractors, utilities and many others participated in the process. The following paragraphs summarize the principle changes that resulted. All Buildings Revisions to the administrative 10-103 sets the format and informational order for electronic compliance document registration and submittal and for electronic retention of compliance documentation, including the nonresidential forms, for future use and clarifies the roles and responsibilities of the documentation author and the responsible person. 1. 10-109 describes the rules for approving compliance software, alternative component packages, exceptional methods, data registries and related data input software, or electronic document repositories. 2. 10-111 describes the rules for reporting fenestration U- factor, SHGC, and VT. 3. 110.3(c)5 explains the requirements for the water heating recirculation loops serving multiple dwelling units, high- rise residential, hotel/motel, and nonresidential occupancies. 4. Revisions to 110.9 now covers ballasts and luminaires and residential vacancy sensors. Non- Residential Buildings Envelope 1. Increased low- slope cool roof requirements (increase reflectance from 0.55 to 0.63 for new construction and alterations). ( 140.3(a)1Aia1) 2. Established a maximum air leakage rate (0.04 cfm/sf) except in mild climate zones. ( 140.3(a)9B) 3.

CALIFORNIA ENERGY COMMISSION PAGE 7 Performance Compliance The modeling procedures and requirements for compliance software have been significantly modified for the 2013 Standards. All compliance software vendors must use a single modeling approach and a single interpretation of the performance compliance rules. This Compliance Manager software will be integrated into vendor- supplied compliance software that is certified by the Energy Commission. More information is available in the 2013 Residential ACM Approval Manual and the 2013 Residential ACM Reference Manual. Additions and Alterations 1. Simplified Compliance documentation requirements for small additions and alteration projects that do not involve a HERS measure. (Section 10-103(a)1C and Section 10-103(a)3C) 2. Simplified rules for both the prescriptive and performance paths for additions, alterations, and existing plus additions plus alterations.
