This 2004 guide by the Rocky Mountain Institute (RMI) provides homeowners with strategies to reduce space cooling costs and energy use. It advocates for a hierarchical approach: first minimizing heat gain through passive measures, then utilizing low-energy ventilation, and finally selecting the most efficient mechanical cooling systems based on climate and budget.

This 2004 guide by RMI provides homeowners with strategies to reduce water heating costs and energy consumption through the use of efficient fixtures, maintenance of existing heaters, and the adoption of advanced heating technologies such as solar thermal, heat pumps, and drain-water heat recovery.

This briefing from Energy Innovation provides a blueprint for U.S. state policymakers to maintain energy efficiency and electrification progress in buildings and industry following the passage of the One Big Beautiful Bill Act (OBBBA), which the author projects will negatively impact the U.S. economy.

This fact sheet details the technical and financial assumptions used in an analysis of heat pump adoption in California, specifying system efficiencies, energy load sources, and utility rates for electricity, natural gas, and propane.

This document outlines the analytical methodology and specific utility-level assumptions used by RMI to estimate changes in residential utility bills under various tariff structures during electrification. The analysis utilizes NREL's ResStock dataset for building load profiles and integrates tariff data from Genability and RateAcuity, with specific adjustments made for utilities in Minnesota, Maryland, Maine, and Massachusetts to ensure consistency and accuracy in bill calculations.
