Solar project description: South Bridge Towers No. 6 multi-family cooperative, New York City, New York
South Bridge Towers, Inc. solar energy system is a high-rise cooperative apartments subdivision located in New York City, New York. The solar energy collector subsystem is located on the roof of the 27-story tower and consists of 150 flat plate collectors arranged in six arrays. The collectors have a total gross area of 3790 square feet and a net aperture area of 3150 square feet. The collectors are inclined at an angle of 40/sup 0/ to horizontal, and oriented to face 14 degrees west of south. Solar energy is stored in a 4000 gallon (nominal capacity) carbon steel tank located on the tower roof. The storage tank has a cement interior lining and the exterior of the tank is insulated with 4 inches of fiberglass insulation which is covered with an aluminum sheet moisture barrier. The solar storage tank, and feed piping located on the tower roof, are protected from freezing by insulation and electrical heat tracing cables. The tank and piping can be drained in event of an electrical power failure during the winter. The system uses a solar energy transport medium of one-half water and one-half propylene glycol in the collector loop. Solar energy, gathered in the collector loop, is transferred to the domestic water storage subsystem by circulating the water through the collector loop heat exchanger and the storage tank. Upon demand for hot water in the apartments, make-up water from the cold water supply flows into the storage tank forcing solar heated water out of the upper part of the storage tank. The water from the storage tank flows into the low-pressure condensate cooler then into the domestic hot water heater tanks where the water is heated to demand temperature by low-pressure steam purchased from the local utility company. The system has two modes of operation: solar heat to storage and storage to load. Original cost estimates for provisioning and installation of the solar system are given.
