ASHRAE/IES Standard 90.1-2022 introduces a new system performance approach (the Mechanical System Performance Rating Method) as a new pathway for HVAC compliance. This method and the metric developed to express the efficiency of the HVAC system—the total system performance ratio (TSPR)—are discussed. Read more
Join David Schurk, Life Member ASHRAE, and ASHRAE Journal’s Technical Editor Rebecca Matyasovski as they discuss ways to avoid wet AHUs and how to move toward more sustainable HVAC systems.
Water Is Weird and Ice Wine Is Delicious With Joe Lstiburek
By Richard Bruns, Ph.D.
The risk assessment committee for ASHRAE Standard 241, Control of Infectious Aerosols, produced a model to predict the reduction in infections as airflow increased. But what are the estimated costs and benefits of operating in Standard 241’s infection risk management mode (IRMM)? In this column, the estimated costs and benefits of operating the IRMM in ASHRAE Standard 241 are explored. Read more

Leveraging Radiant and Hydronics to Achieve Decarbonization Goals
With energy efficiency being one of the four decarbonization pillars in the U.S. Department of Energy’s Industrial Decarbonization Roadmap, the goal of achieving a low-carbon economy and attaining carbon neutrality is possible with the use of radiant heating and cooling, hydronic hot-water heating, and chilled-water systems. Discover how thoughtful design with these durable, sustainable, polymer-piping based applications can provide a compelling solution for comfort, efficiency, air quality, and other IEQ benefits while also helping projects meet construction schedules and budgets.
