Project:
Federal Courthouse aged mechanical system have become inefficient and costly to operate. Comprehensive replacement of AHU's; lighting fixtures will need to be more efficient. Both systems to be controlled with energy management program. Additionally the facade deterioration will need substantial restoration.

Details:
Heating, Ventilating, Air Conditioning, and Controls Upgrades:

  • Replace the existing multi-zone air handling units on all floors (except recently replaced air handlers) with new VAV air handlers, to improve the efficiency of air distribution and heating and cooling coils.

  • In historic areas, provide new by-pass type multi-zone units (compartment design for ease of installation).

  • Provide new direct digital controlled (DDC) HVAC building automation system capable of adjusting hot water boiler loads, chiller loads, multi-zone air handling loads, and VAV loads to meet requirements based on current temperatures and zones.

  • Supplement existing gas fired steam boilers with (2) high efficiency gas hot water boilers to provide base heating capacity.


Water Reduction:
In Public Restrooms, replace existing water closets, urinals, and lavatory faucets with low flow fixtures and low flow faucets. Capture existing roof drain water into new water tank cistern; replace water supply to existing exterior site irrigation system, replace existing irrigation control manifold and pumping system.

Lighting:
Replace lighting fixtures in office areas with high efficiency fluorescent “T -8” lights (existing fixtures have T-12 lamps). Provide daylight harvesting lighting controls (in all areas with windows) and occupancy sensors in all office areas.

ARRA Facade Restoration:
Proposed work included stone repair, stone replacement, flashing repair, tuckpointing, and cleaning. The building was occupied throughout the construction.

Obtain a LEED “Silver” Certification upon completion of work.
