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.
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.
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.
Although it’s only 25% complete, the Central Ohio Transit Authority’s (COTA) ongoing $75 million conversion to compressed natural gas (CNG) fueled buses is already saving more than 2.5 million gallons of diesel fuel and emitting 100 tons less bus emission contaminants annually in the greater Columbus, Ohio, area.
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.
