60+ Years of Design + Innovation

Engineering NASA's
First LEED Platinum Project

NASA Johnson Space Center Building 20
Houston, Texas, USA

“We are extremely proud of the record of green building we are establishing at JSC. We plan to continuously reduce the impact of JSC on the environment while providing the highest quality workplace for the special skills and talents of NASA.”

Joel Walker
Operations Director, Johnson Space Center

NASA’s new LEED Platinum office facility is a model for environmentally sound, high-performance buildings across the agency.

The energy-efficient building is modeled to perform 57 percent better than a typical facility complying with ASHRAE’s energy code. The design team’s integrated architectural and engineering solutions include a highly efficient building envelope, an underfloor air distribution system, total energy recovery and a solar hot water harvesting system.

Total energy recovery is especially appropriate for Houston’s hot and humid climate. By using a total energy wheel to pre-condition incoming outdoor air, NASA can achieve considerable energy cost savings.

HVAC systems incorporate variable frequency drives for fans and pumps that are controlled to optimize system capacity in response to varying loads. Unoccupied temperature set-back and ventilation demand control using carbon dioxide sensors and occupancy sensors have interactive direct digital controls that adjust temperatures and reduce outdoor air and exhaust during unoccupied periods.

Lighting systems include energy-efficient lamps, high power factor ballasts and high-efficiency fixtures. A low-voltage lighting control system uses occupancy sensors, daytime harvesting, timer sensor switches, photoelectric sensors and override switches.

Plumbing systems incorporate water-saving strategies, cooling coil condensate collection for irrigation and solar-assisted water heaters to reduce energy.

Solar hot water harvesting system consists of flat-panel solar collectors located on the roof, as well as an indoor solar water storage tank, solar hot water circulating pump and heat exchanger.
