Ground Source Heat Pumps - Bldg 1, Naval Observatory, Washington DC

This project provides ground source heat pumps for Bldg 1, which is eligible for classification as a historical site. Therefore, the HVAC design takes into account the historic surroundings and is virtually hidden. Mechanical work involves the replacement of the HVAC system including all fan coil units, piping, ductwork, air handling units, hot water generators, steam to hot water converters, insulation, diffusers, etc. Plumbing work removes all ceiling-hung supply, return and drain piping. New HVAC system requires interior supply, new return and drain piping and exterior piping for ground heat exchanger. Electrical work replaces electrical equipment associated with the new HVAC system: Starters, disconnects, wiring, conduit, etc.
