AHR Expo, ASHRAE Journal 2024, Chicago
By Andy Pearson, Ph.D., C.Eng., Fellow ASHRAE
It's that time of year again. Later this month ASHRAE will gather in Chicago, and we will hurry from hotel to conference hall or convention center trying to keep out of the cold as best we can. If you have to "winterize" your plant, I hope you have already done so; otherwise, it's probably too late. Read more
By David Claridge, Ph.D., P.E., Fellow/Life Member ASHRAE; Jiajun Liao, Ph.D., P.E., Member ASHRAE; and Linyan Wang, P.E.
A building cooling and heating system coefficient of performance is introduced as part of a more general measure called the building systems load/energy ratio. This article includes information on comprehensive HVAC system efficiency measures, including the impact of reheat and multiple energy sources. Read more
Strainers and Their Uses in Hydronic Systems
Join ASHRAE Journal Editor Drew Champlin and Mike Gallagher as they discuss how strainers are used in hydronic systems along with the differences between wye, basket and inlet strainers and address common mistakes when applying strainers.
Mike Gallagher, P.E., Fellow/Life Member ASHRAE
By Joseph W. Lstiburek, Ph.D., P.Eng., Fellow ASHRAE
Columnist Joseph Lstiburek discusses why the environmental separator you use in a building matters, how we are currently fumbling energy codes and how to construct buildings that meet the modern day needs of the built environment. Read more

Building Performance Analysis Simulations From Your iPad
Join this webinar to learn how cloud-native engineering simulation is used to evaluate thermal comfort and HVAC design.
The use of computational fluid dynamics (CFD) at the early design stage is becoming more common as cloud computing delivers an order of magnitude faster simulation times, automated meshing, team collaboration, and powerful integrations with CAD/Visualization tools.
