When it comes to ductwork for VAV systems, could the shortest path to better air handling cost and efficiencies be round (or spiral)? Aided by static regain and streamlined installation, here’s the case for no more corners.
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.
This chiller plant retrofit team encountered challenging existing conditions and an-swered with savvy choices for piping and valves as well as the chillers. Good communication, accurate documentation, and a creative bidding idea you might want to borrow also contributed to bringing the mechanical work in effectively and on budget.
Many engineers tend to avoid or delegate the nitty gritty of a ground source heat pump system, from soil moisture effects to building system (im) balance. It's time for designers to get in the loop.
