The Cold Climate Heat Pump Technology Challenge (CCHPTC) is a program designed to help manufacturers speed the development of the next generation of heat pumps and ensure that they will perform reliably during chilly winters in North America.
ASHRAE Standard 241, Control of Infectious Aerosols, establishes minimum requirements for reducing the risk of the transmission of airborne pathogens, such as the SARS-COV-2 virus, which causes COVID-19.
The standard applies to new and existing buildings and major renovations and provides requirements for many aspects of air-system design, installation, operation, and maintenance.
