Connecticut

Connecticut established the nation’s first green bank in 2011 and has since leveraged more than $2.43 billion of clean energy investments into the state’s economy. From 2001-2021, the state reduced greenhouse gas emissions by 17%. Connecticut has no fossil fuel reserves but more than half of the state’s generated electricity is sourced from natural gas. Connecticut uses less energy per-capita than 46 other states.

Glossary of Terms

Status	Policy	Policy Area	Policy Category	YR Enacted
Enacted	Commercial Energy Codes Empty column The statewide energy code for commercial building construction is 2021 IECC and ASHRAE 90.1-2019. Establishing Policies Connecticut State Energy Code (2022)	Buildings and Efficiency	Building Codes	2022
Enacted	Residential Energy Codes Empty column The statewide energy code for residential construction is 2021 IECC with amendments. Establishing Policies Connecticut State Energy Code (2022)	Buildings and Efficiency	Building Codes	2022
Not Enacted	Stretch Building Energy Codes Empty column Stretch building energy codes are an optional, more stringent building code established by the state that local jurisdictions can adopt to require that newly constructed buildings are more efficient than the baseline state codes.	Buildings and Efficiency	Building Codes
Enacted	Appliance Standards Empty column The Small Product and Appliance Energy Efficiency Standards apply to 21 products. Establishing Policies C.G.S. Section 16a-48, Chapter 298 (2011) Executive Order 21-3 (2021) Product Efficiency Standards	Buildings and Efficiency	Building Standards	2011
Not Enacted	Building Performance Standards Empty column Building performance standards establish energy and/or greenhouse gas performance targets for existing buildings in a state. These targets increase in stringency over time, leading to efficiency improvements in buildings to conserve energy and reduce emissions.	Buildings and Efficiency	Building Standards
Not Enacted	Clean Heat Standards Empty column Clean heat standards establish a performance standard requiring heat providers to deliver a gradually-increasing percentage of low-emission heating services to customers.	Buildings and Efficiency	Building Standards
Enacted	Energy Efficiency Resource Standards (EERS) Empty column Electric utilities are required to achieve energy savings of 524 gigawatt hours (GWh) for 2022-2024. Gas utilities are required to achieve energy savings of 1,424 million cubic feet (MMcf) for 2022-2024. Establishing Policies Connecticut General Statutes § 16-245(m) (2014) Connecticut General Statutes § 16-32(f) (2015) 2022-2024 Conservation & Load Management Plan (2022)	Buildings and Efficiency	Building Efficiency	2022
Enacted	Property Assessed Clean Energy (PACE) Empty column Connecticut has enacted commercial PACE-enabling legislation and has active programs. Establishing Policies SB 501 (2012)	Buildings and Efficiency	Building Efficiency	2012
Partially Enacted	Weatherization Funding Empty column The State Policy Opportunity Tracker (SPOT) breaks clean energy policies down into “components”, which are binary questions to evaluate policy quality. Higher quality policies have more of their SPOT components fulfilled. Establishing Policies SPOT - Weatherization Funding in Connecticut Policy Components not-enacted enacted enacted enacted 3/4	Buildings and Efficiency	Building Efficiency
Not Enacted	All-Electric Buildings Empty column All-electric buildings policies require new buildings to be constructed with all-electric heating, cooling, and cooking systems to transition away from fossil-fuel use in buildings.	Buildings and Efficiency	Building Electrification
