A zero net energy (ZNE) building is a home or commercial building that on average produces as much energy as it uses, achieved through energy efficiency and renewable technologies. Building energy codes can help us transition to ZNE construction for new residential and commercial buildings by 2030. We will need to expand the scope of codes to capture all building energy uses, address whole building systems instead of focusing on individual components, and shift our focus from building design to actual building energy use by adopting outcome-based codes. We should also ensure ZNE performance post-occupancy by considering the impact of building occupants and operators and by incorporating future-proofing measures. By addressing these areas, we can establish the foundation for ZNE by 2030 while providing energy savings and related benefits in the interim. Complementary policies, targeted research, market transformation, and the coordination of efforts and advocacy will help us achieve these goals.
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…
