The design for the US Department of Fish & Wildlife’s new headquarters in an existing building required updating MEP systems to meet GSA standards. This included selective demolition of existing infrastructure components, design of new components, and reconfiguration of existing infrastructure as allowed. In the building lobby, GHT upgraded electrical service to meet GSA power requirements for entry and screening equipment.
The project achieved a certification level of Gold under the LEED for Commercial Interiors™ rating system. Sustainable design features include:
- LED lighting
- Daylight harvesting
- Occupancy/vacancy sensors for 75% of connected lighting load
- Submetering of tenant energy use
- 90% ENERGY STAR equipment
- 35% reduction in water use compared to a baseline building
- Lighting design offers 10-15% improvement over the ASHRAE 90.1-2007 standard of 1.0 w/SF
The space is conditioned by chilled water variable air volume (VAV) air handling units (AHUs) that provide conditioned air to VAV terminal units. Temperature controls were provided for every 1,500 SF of office space and are located in each special occupancy area. Perimeter and interior spaces are zoned separately for temperature control.
