Deep Energy Reductions
Deep energy reductions are whole-house retrofits that reduce a home's energy consumption by 70% or more and go beyond conventional upgrades, such as replacing HVAC equipment and other household appliances, to address all of the systems in a home that affect energy use.
1000 Home Challenge
The Thousand Home Challenge aims to transform North American housing stock through deep enegy reductions and provides a roadmap for homeowners, building professionals, and communities to develop deep integrated solutions to the problems of housing affordability, durability, and sustainability. These reductions will be achieved through a combination of energy efficiency, renewable resources, community-based solutions, and behavioral choices. Learn more.
