This statement from RMI argues that Massachusetts Governor Charlie Baker's veto of bill S.2995, which included a net-zero stretch code, contradicts state research and economic realities. The document asserts that electrification of new buildings is essential to meet the state's 2050 net-zero carbon emissions target and is already economically viable for single-family homes and affordable housing developers.

The Community Energy Resource Guide, published by the Rocky Mountain Institute (RMI) in December 2015, provides a comprehensive roadmap for U.S. communities to develop energy action plans. It outlines a collaborative planning process, methods for analyzing energy landscapes, and specific tactics across the buildings, electricity, transportation, and industry sectors to accelerate the adoption of renewable energy and energy efficiency.

This 2011 fact sheet explains district energy systems, which use central plants and underground pipes to provide efficient heating and cooling to clusters of buildings. It highlights the role of combined heat and power (CHP) and renewable energy in these systems, noting that while over 700 such systems exist in the U.S., high upfront costs and policy gaps remain barriers to further expansion.

This guide by the World Resources Institute (WRI) provides local governments with a framework for sourcing and collecting the data necessary to conduct a 24/7 carbon-free energy (CFE) analysis. It outlines the three primary datasets required—hourly load data, grid mix and emissions data, and additional energy procurement or generation data—and offers various methodologies for estimating these values when actual data is unavailable.
