The relationship between indoor air quality (IAQ) and the K-12 student experience has been a topic of study for decades. 

The 2019 edition of ANSI/ASHRAE/IES 90.1, “Energy Standard for Buildings Except Low-Rise Residential Buildings (ASHRAE 90.1),” adopts a new fan efficiency metric, Fan Energy Index (FEI). 

An increasing emphasis on variable speed pumping as a means to save energy in commercial buildings has provided engineers with many paths to efficient hydronic system design.

Beginning Jan. 27, 2020, clean water pumps sold in the United States must achieve a minimum energy rating of 1.0 as outlined in the Energy Conservation Standards for Pumps established by the U.S. Department of Energy (DOE) and adopted by Natural Resources Canada.

Ten years in, the size of data centers has increased up to 5 to 10MW, and the wholesale real estate market took hold.

Artificial intelligence (AI) leads the charge in the current wave of digital transformation underway at many global companies.

As the demand for electrical power increases, distribution systems are expanded to accommodate the increased demand. Stiffened transmission systems, increased substation capacity, and added on-site and distributed generation all contribute to increases in available fault currents.
