The U.S. Department of Energy has released a guide on electrifying space heating for large commercial buildings with boilers.
The guide summarizes key considerations for people seeking to retrofit existing large commercial and multifamily buildings, particularly those that currently heat spaces using fossil fuel-fired boilers. It provides an overview for building owners, contractors, and other stakeholders involved with heating, ventilation, and air-conditioning (HVAC) about possible design and purchasing decisions.
It includes discussion of motivations for electrification, electric space heating technologies, boiler retrofit evaluations and processes, and other project considerations. The document provides case studies that demonstrate best practices and lessons learned.
Although the topic of commercial building electrification has seen increased interest in recent years, most projects and case studies focus on new construction rather than retrofitting existing systems, which make up the vast majority of commercial buildings, DOE says.

The perception that the U.S. has not been able to curb development in flood-prone areas is mostly inaccurate, according to new research from climate adaptation experts. A national survey of floodplain development between 2001 and 2019 found that fewer structures were built in floodplains than might be expected if cities were building at random.
