A military hospital in Fort Belvoir, VA is using a heat recover chiller system as part of a strategy to reduce energy costs by 27%. The hospital, which opened in 2011, is the first US hospital built to LEED Silver Status according to ContractorMag. While hospitals are noted for their energy consumption, this one is working toward energy efficiency.
The hospital uses a Multistak heat recovery chiller to help reheat the building. High efficiency variable speed drive chillers and variable speed air fans ensure less energy is wasted. The hospital added these features to its design after a life cycle cost analysis found them to be the best option.
Waste heat from fan coil units help provide energy for cooling while additional energy is captured from cooling coils in the air handling units. The building is also using lighting and thermal controls and occupancy sensors and optimizing available daylight to help trim energy bills.
The hospital is reducing water consumption, saving an estimated 1.6 million gallons a year, through a combination of low-flow plumbing, sensor activated faucets and an innovative integrated rainwater and condensate water collection system. The collection system alone can capture and store up to 160,000 gallons of reusable water.
