When the City of Tallahassee and Leon County collaborated on a consolidated public safety complex to deal with local emergencies, the stakes were high and the need for robust yet adaptable HVAC was, too. Another collaboration within the design — chilled beams and pump technology — represented a key component of the mechanical system as it stands ready for severe swings in occupancy and weather alike.
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.
Cornell’s Bill and Melinda Gates Hall required a suitably thoughtful design process. After considerable analysis, an unusual strategy emerged, led by chilled beams and DOAS with key dehumidification elements.
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.
