Momentum Q1 | 2026
From the ever-expanding energy demand of data centers and AI-driven campaigns to weaken appliance standards, to the growing list of repealed regulations intended to protect public health and the environment, 2026 looks different from the future many of us envisioned when we began working on building decarbonization.
Beyond the Building: Strengthening Neighborhood Resilience Through Energy Efficiency Programs
ACEEE researchers find that energy efficiency upgrades and heat pumps installed in multiple buildings in an area provide benefits beyond each individual building by reducing local peak demand and the likelihood of outages. An analysis of commercial and residential buildings in Westchester County, New York finds that building envelope sealing and heat pumps in multiple buildings reduce summer peak demand by 8 percent and outage time by 63 percent.
Momentum Q2 | 2025
The Buildings Decarbonization Coalition details developments in the second quarter of 2025, including the latest HVAC sales figures, updates on utility rate cases, prominent state policies, and a preview of the next quarter.
Lower Bills, Cleaner Air: Heat Pump Benefits for Homes Relying on Delivered Fuels
RMI's analysis finds that households in the United States using delivered fuels for space and water heating could save an average of $970 per year by upgrading to heat pumps.
Multistate Action Plan: Accelerating the Transition to Zero-Emission Residential Buildings
The signatory states are working through NESCAUM's Building Electrification Task Force to develop a Multistate Action Plan with policy and program recommendations to advance affordable, zero-emission heating and clean residential buildings.
A Blueprint for HOA Electrification
This case study from TECH Clean California lays out how the Heather Village homeowner's association leveraged grants and utility financing to switch from gas boilers to heat pumps to heat its residents' water.
The Energy Code Safe Harbor Toolkit
To help cities and states successfully advance zero-emission new construction for commercial and residential properties with confidence, RMI and the Public Health Law Center have collaborated to release the Energy Code Safe Harbor Toolkit.
