In 1979 legislation was passed requiring that the State Building and Fire Safety Codes (SBC) promote and ensure design and construction of energy-conserving buildings and the use of renewable resources. In 1988 provisions were included in the enabling legislation requiring revision of the state building code no later than July 1989, in order to incorporate necessary 1988 BOCA International revisions into the state building code. Furthermore, future revisions were limited to occur not more than every four years thereafter.
On June 4, 2007, the governor signed Public Act 07-242 into law that will require all buildings except residential buildings with less than five units that are projected to cost $5 million or more to qualify for a LEED-Silver rating or an equivalent standard, such as a two-globe rating under the Green Globes USA design program.
The 2009 Amendment to the 2005 State Building Code updated the energy code for residential and commercial buildings to the 2006 IECC. The final proposed draft of the State Building Code 2009 Amendment proceeded through the regulatory adoption process and became effective on August 1, 2009.
A second 2009 Amendment to the 2005 State Building Code revising Chapter 541, Sec. 29-256a of the General Statutes of Connecticut (to comply with Public Act 07-242) requires all buildings except residential buildings with less than five units that are projected to cost $5 million or more to qualify for a LEED-Silver rating or an equivalent standard, such as a two-globe rating under the Green Globes USA design program. The same is required of renovation projects that are expected to cost $2 million or more. Due to the problems of enforcement, efforts are underway to propose overriding legislation to remove the requirement but keep the state on a path to strong energy codes.
A state bill (HB 6284) to update the state energy code and to create green building standards was passed by the legislature and signed by Gov. M. Jodi Rell on July 8, 2009. The bill requires the State Building Inspector and the Codes and Standards Committee to revise the State Building Code to incorporate the 2012 IECC within 18 months of its publication for commercial and residential buildings. It also would require a LEED-Silver rating for new construction greater than $5 million AND renovations greater than $2 million.
On September 27, the Department of Public Safety adopted the 2011 Amendments to the 2005 State Building Code to adopt the 2009 IECC. After submitting the rule to the Secretary of State, the new code will be effective October 7. The state had previously updated its energy code through the 2009 Amendments which adopted the 2006 IECC on August 1, 2009.
