High Performance (Green) Building Standards for
State Agency Buildings and School Buildings
2023 Update-Connecticut High Performance Buildings
Connecticut’s green construction standards help achieve the state’s greenhouse gas emission (GHG), energy, and cost reduction goals while driving economic growth. The Connecticut General Assembly passed Public Act 19-35 , titled “The Green Economy and Environmental Protection” bill, which amended the state building construction statute (CGS §16a-38k). Now, DEEP is required to adopt high performance building regulations (HPBS) that incorporate by reference a national sustainable construction code.
DEEP has recently completed its review of the nationally recognized green model codes. The 2021 International Green Construction Code (IgCC) with amendments will serve as the states modernized HPBS. This sustainable building code delivers buildings that have fewer negative impacts on the environment. These buildings produce fewer GHG emissions, use less energy, support better indoor air quality, and improve occupant comfort. DEEP staff are drafting these modernized green construction standards now.
Until the state adopts the new green construction standards, projects are required to comply with the current HPBS. Project compliance with the 2021 International Energy Conservation Code satisfies the energy performance requirement. Please use these resources to support project compliance.

Background
Since 2007, Connecticut law has mandated high performance efficiency buildings (CGS § 16a-38k). As required, DEEP has adopted high performance (Green) building construction regulations that incorporate design, construction, and operation practices that preserve the natural environment (RCSA 16a-38k 1-9). These state construction standards are consistent with, or in some cases, have exceeded the Leadership in Energy and Environment (LEED) silver design building rating system.
