A pre-retrofit report card helped this major Chicago health care facility chart a smart course of treatment for its HVAC. After improvements for chillers, cooling towers, refrigerants, pumps, and more, the hospital’s central plant upgrade now looks forward to long-term savings, cleaner operations with streamlined maintenance, and better reliability.
In which CFD modeling lets us compare two possible design configurations for ventilation in a hospital patient room, yielding some similarities and perhaps surprising differences in what each configuration means for pathogen control and occupant comfort.
Simple versus oversimple, Matchmaker versus Master, innovation versus inertia … our veteran data center expert looks back on time spent with an industry leader and looks forward with some lessons in mind.
The Museum of the Bible’s project team was already up against the extremes of Washington weather and the high demands of IAQ for artifact preservation. A system that harnessed adequate cooling, heating, humidification, and ventilation capabilities would still have one more hurdle: a physical footprint of hardly Biblical proportion. Get a first look at this testament to design acumen and true collaboration.
In which the design team realized they could pump irrigation water from the campus’ main distribution line at night to use for cooling during the day if they could figure out how to store thousands of gallons of water on the new building’s first floor -- a vertically small space. Piping strategy, CFD, and chilled beams fill out an innovative closing argument on behalf of this Utah law school.
Leaning on experience and data from various K-12 cities and projects, the author pursues some less conventional design approaches. They may revolve around radiant heating and/or cooling, but depending on school size and other factors, the smart use of heat recovery, DOAS, and improved central plants could also put a project on the HVAC honor roll.
