The U.S. Department of Energy and the North Carolina Clean Energy Technology Center are excited to announce that a new, modernized DSIRE is under construction. The new version of DSIRE will offer significant improvements over the current version, including expanded data accessibility and an array of new tools for site users. The new DSIRE site will be available in December 2014. Staff are currently working hard on the new version of DSIRE but are also maintaining the content of the current version of DSIRE. Thank you for your continued support and patience during this transition. We hope you are as excited for December as we are!

NOTE: Much of the information presented in this summary is drawn from the U.S. Department of Energy’s (DOE) Building Energy Codes Program and the Building Codes Assistance Project (BCAP). For more detailed information about building energy codes, visit the DOE and BCAP websites.

The Connecticut Office of the State Building Inspector establishes and enforces building, electrical, mechanical, plumbing and energy code requirements by reviewing, developing, adopting and administering the state building code. Compliance is determined through construction documents submitted to the relevant local building official showing detailed building data and features, and equipment systems governed under the code. Variances and interpretations of the code are granted through the Connecticut Department of Public Safety.

HB 7432, enacted in June 2007, added provisions to strengthen the state's building code, and required the state building inspector and the Codes and Standards Committee to revise the state building code by January 1, 2008. The new code applies to all buildings (including residential buildings) and is designed to provide optimum cost-effective energy efficiency over the useful life of the building. HB 6284 of 2009 further required the state building inspector and the Codes and Standards Committee to adopt the 2012 version of the IECC within 18 months of its publication.

HB 7432 also created a requirement for certain building projects (not including residential buildings with less than four units) to follow approved green building guidelines. The provision applies to buildings constructed after January 1, 2009, that are projected to cost at least $5 million, and building renovation projects started after January 1, 2010, that are projected to cost at least $2 million. The bill required building projects which meet this criteria to achieve a silver rating from LEED, a two-globe rating in the Green Globes USA design program, or an equivalent standard. After enforcement difficulties for this provision were identified, HB 6284 of 2009 revised the requirement so that the affected buildings do not have to be certified under these green building programs, but must simply be designed to adhere to their specifications. The state building inspector and the Codes and Standards Committee will adopt provisions within the state building code specific to these building types that reference these green building certification programs, but allow building owners to demonstrate compliance through means other than certification under those specific certification programs.
