The building sector is the largest contributor to climate change in Connecticut.

Without meaningful legislative action now, we could end up spending millions of dollars on new and renovated buildings that lock in decades of wasted energy, air pollution, and avoidable greenhouse gas emissions.

to reduce emissions and improve health.

Local governments see the impacts of climate and air pollution firsthand, but are unable to require greater levels of energy efficiency than the State Building Code. The ability to adopt a stretch code would allow cities to lock in energy savings and public health benefits for years to come.


Enacting an energy stretch code would put Connecticut in line with Massachusetts, New York, and Vermont, all of whom give municipalities the ability to protect the health and financial wellbeing of their residents through greater building energy efficiency.

Knowing your home's energy efficiency before purchasing or renting is essential consumer protection. Especially in Connecticut, with the second-highest energy burden in the nation, our residents need to be able to make informed decisions about their most significant purchase. 


Many other jurisdictions already mandate some form of energy-consumption reporting. This reporting would encourage energy efficiency retrofits and help homeowners and landlords market their energy-efficiency upgrades in the real estate market.

Combusting fossil fuels inside of buildings causes indoor air pollution. In homes, this can produce air pollution at levels up to 10x beyond the thresholds set by the EPA for healthy outdoor air, and is estimated to be responsible for billions of health impact costs every year in the State of Connecticut.

The combination of efficient heat pumps and our current electrical grid results in fewer greenhouse gas emissions than using the most efficient gas furnace.

The energy from electric heating and cooking appliances can be offset with clean renewable energy with solar panels onsite or an increasingly clean electric grid.
