To ensure that sufficient capacity is always available for cooling this around-the-clock operation, the chiller has twice the capacity needed to satisfy the design load. The BMS is programmed to equalize the runtimes of the building’s four chiller barrels. Interior lighting is controlled with occupancy sensors and continuously dimmable ballasts. To ensure air quality inside and outside the building, the indoor
firing range is exhausted through HEPA filters and supplied with 100% outside air. The range is served by two air-handling units, each outfitted with a heat-pipe recovery coil.

exhaust airstream is recovered and used to temper the makeup air. Sufficient cooling is provided by the high velocity laminar flow of the range’s airstream so that mechanical cooling was deemed unnecessary.
