This past May I wrote in the Back2Basics column about the design intent of a small city school system that chose to invest in an annual contract for a temporary air-cooled chiller for special events and emergency crisis shelter center.
When the Pina Bausch dance company came to the University of California (UC) Berkeley for a weekend of live performances presented by Cal Performances in December 2011, the theater’s production team faced an unusual challenge. The show incorporated a vintage 1940 slide projector being shipped from Germany for use in the Zellerbach Hall auditorium, and Doug Warrick, general manager of Cal Performances, had to find a way to ensure that noise and heat buildup from the projector would not ruin the performance or, worse yet, create a fire hazard in the theater.
A learning environment adds extra meaning to the risks of “run to fail” mode, which can have the same effect on the budget as it does on the equipment. Covering everything from specification to installation and operation, schools need a permanent plan on hand for the moment when temporary HVAC becomes necessary.
School districts have known for quite some time that temporary equipment can assist in passing the tests of renovations or the pop quizzes of unexpected equipment failure. The lesser-known lesson is that having the plan in place can save significant time and money on top of the equipment’s basic benefits.
Retrieving every last bit of performance from the system while stopping short of the surge line is no small feat. Dig into sizing, tower selection, chilled water loads and stability, and condenser water management to leave no efficiency stone unturned. Read more in April issue
