The Federal Emergency Management Agency (FEMA) recently unveiled new guidance on additional assistance funding for net zero buildings. This funding is available for net zero energy projects related to disaster recovery or mitigation. To qualify, projects must meet or exceed energy performance thresholds and renewable generation requirements specified in the zero energy appendices of the 2021 International Energy Conservation Code (IECC). Read more
Scientists and collaborators from the Technical Institute of Physics and Chemistry of the Chinese Academy of Sciences have developed an innovative heat-driven thermoacoustic refrigerator (HDTR), which uses a novel bypass configuration that significantly improves efficiency. The efficiency of HDTRs can be estimated by the coefficient of performance (COP), i.e., the ratio of output cooling power to input heating power. For existing advanced direct-coupled HDTRs, the researchers found an unexpected decrease in COP with increased heating temperature. Read more
The U.S. Department of Energy (DOE) announced the availability of $63M in funding aimed at ramping up the production of residential heat pumps, heat pump water heaters and other related systems and components. The announcement is the latest in an array of clean energy projects, with the DOE recently announcing sizable funding for geothermal energyRead more

The EPA unveiled stricter limits for PM2.5 particles, commonly referred to as soot, reducing the allowable limit for annual PM2.5 levels from 12 micrograms per cubic meter to 9. The new standard represents the first tightening of the rules since 2012, but states will have several years to reach the new limits. Tighter standards may prevent an estimated 4,500 premature deaths and 800,000 asthma-related emergency visits by 2032 and could reduce health-care costs by about $46 billion. Read more
