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.
Are we headed for a scenario reminiscent of big-budget disaster films? Maybe not. But when it comes to water usage, it’s time for engineers to put down the popcorn and embrace a new role: designer of more responsible data centers. Optimizing cooling towers, boosting the CoC, and considering your WUE are just three steps for maintaining the flow of information while minimizing the flow of H2O.
Pressure independent control valves proved to be a key in wringing the benefits out of smartly managed chilled water temperature, but that wasn’t all. Airside energy recovery, desiccant dehumidification to eliminate reheat in operating room environments, and upgrading to ECM fan systems have all contributed to this hospital’s fiscal wellness.
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.
