Large multifamily buildings with central heating systems that burn fossil fuels are among the hardest to decarbonize, but new systems such as window-mounted heat pumps, central air-to-water heat pumps and “mono-block” mini heat pumps provide new options for decarbonizing these buildings. We find that of the decarbonization options, window heat pumps generally have the lowest life-cycle capital and energy costs.
This report discusses these and other decarbonization options for centrally heated multifamily buildings, analyzing the life-cycle cost of the different options and providing examples of installations using each of these options. Program and policy approaches to improve decarbonization economics and other near-term steps to further use of heat pumps in these buildings are discussed.
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…
