Chicago’s Michael A. Bilandic Building has 21 stories, one for each year since the previous retrofit. Recently, an open-minded project team paired modular chillers and hydronic gas boilers with pumps and VFDs to conquer some upgrade challenges, bring the mechanical system into the 21st century, and knock 15% off the tower’s measured energy use.
From temperature differential’s effect on pumps over to an airside
design that covers all the bases for comfort and efficient
ventilation, the authors are combining preparation and innovation to
give Tuscaloosa’s new federal building a suitably exemplary
feel.
Software monitoring saved a San Diego pharmaceutical lab 45% in energy costs.The U.S. pharmaceutical industry consumes nearly $1 billion in energy annually. Lab facilities often have environmental and cleanroom requirements
Maybe

cooling tower that isn’t towering enough. Or it arose in
installation - say, misconnected coils. Even then, a fix may create
a new water mystery. Get in step with some successful detecting
