This report explores energy efficiency programs that target deep energy savings through substantial improvements to existing residential buildings. As states and regions set targets for reducing building-sector energy consumption, it is increasingly critical to scale up deep energy retrofit work. Only one utility-scale deep energy retrofit program exists at present in addition to several research and development projects.
Deep energy retrofits aim to save 50% or more of the energy used on site in a home as compared to actual pre-retrofit usage or an estimate of energy use based on housing and climate characteristics. These savings are realized through improvements to the building shell including insulation and air sealing, and often through upgrades to high-efficiency heating, cooling, and hot water systems suited to the smaller energy load of the house.
This report presents findings in four areas: workforce, retrofit measures, costs, and energy savings. We conclude by identifying barriers to scaling up deep retrofit work and strategies for overcoming them.
The commonwealth spends almost $11 billion a year buying energy from out of state. Mass Save lowers bills and keeps money at home.
Utility energy efficiency programs have increased investment in low-income households, but significant gaps remain. This report examines spending and savings trends across 48 major U.S. utilities, identifies barriers to expanding low-income programs and highlights policies and program strategies that can improve energy affordability and equitable access to efficiency upgrades.
The United States faces interlocking energy challenges: rising home energy bills and gasoline prices; new demand for electricity from data centers and other loads; high greenhouse gas emissions from burning fossil fuels.
Now, a new era of energy efficiency progress in our buildings, transportation, and industry is needed to meet this moment. This wide-ranging study finds a massive opportunity.
Home energy report programs, in which utilities provide households with personalized insights into their energy use and tips to lower their bills, are a…
