As HVAC system manufacturers and users explore multiple avenues for improving overall equipment effectiveness (OEE) and minimizing GHG emissions from their systems, hydrogen presents a bold new opportunity — potentially providing the clean energy source the world needs for the future.

Sustainability and decarbonization are top priorities for companies.

This article explores how to refine and enhance the efficiency of pumping to match precisely to load, balancing the interests of pump experts — favoring primary-secondary piping — with those on the “boiler side” who prefer a variable speed/variable flow approach.  

Research suggests the concentration of toxins, allergens, and other pollutants can be up to five times higher indoors than outside, and cooking emissions are considered one of the largest sources of air pollution at home.

Comments, along with a copy of the proposed Normative Sections can be obtained by contacting David Bixby, ACCA manager of codes and standards.

Redelman discusses the advantages of mixed reality headset adoption in the construction, multitrade and engineering industries.

ASHRAE announced new members for its Hall of Fame, YEA Inspirational Leader Award, John F. James International Award, E.K. Campbell Award of Merit, F. Paul Anderson Award, the Setty Family Foundation Applied Engineering Challenge, Student Design Competition, ASHRAE Technology Awards and more.

Master planning today will help you avoid future failure.

Making specific design decisions at the project's outset can have long-lasting consequences. It's crucial to grasp these implications and effectively communicate them to the decision-makers.

Electrode boilers have existed in various forms for many decades. However, recent design improvements have closed the output gap while surpassing conventional units — not only in terms of efficiency and simplicity but also responsiveness and safety.
