TDE provided mechanical, plumbing and fire protection design/build services for the 72 Townsend Street residential conversion project located in San Francisco, California. The project consisted of the renovation of an existing one-story historical warehouse and a new seven-story addition for use as a residential loft and retail building spanning 150,000 sq. f.t. The new development includes a total of 73 residential for-sale condominium units and approximately 3,000 square feet of tenant amenity spaces including a swimming pool, spa and fitness room. The existing warehouse envelope will house retail, the residential entrance lobby, utility spaces, residential storage rooms, a wine storage room and 73 parking spaces. The high-rise building also has a common outdoor living space on the roof level.

The building design focused on maximizing passive systems such as natural ventilation, thermal mass and natural daylighting throughout the development.  Heating and cooling is provided to the condo units by the use of water-source heat pumps. Tempered ventilation air is supplied to the units via a 100% outside make-up air unit located on the roof.  The plumbing systems were designed to minimize potable water usage through low flow fixtures. The building is also fully equipped with a hydraulically designed sprinkler system.
