Green Energy Technology

Enacted in June 2007, HB 2620 introduced a unique requirement for installing solar systems for public buildings. In 2012, SB 1533 amended the requirement to allow the use of any Green Energy Technology (GET). As of January 1, 2020, GET has been defined as energy systems that employ:

  • Geothermal electric
  • Geothermal direct use
  • Solar electric
  • Solar thermal
  • Passive solar
  • Battery storage equipment paired with the above

Eligble Alternative technologies include:

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.
