Savoy Commerical Properties

Savoy Commercial Properties, owner and manager of more than US$50 million commercial real estate properties in northern California, wanted a building-integrated photovoltaic solar roofing system based on silicon cells and single-ply membrane never before installed on a large scale commercial project. When it was first completed, this was the most technologically advanced solar installation in the U.S.

The 40.5kW system was completed in San Francisco, California and now generates 50,000kWh of renewable electricity annually. The system is made up of silicon solar cells built into single ply membrane roofing “sheets.” Sheets of 60 mil PVC roofing membrane are rolled onto the roofing surface and sealed with hot air welding create a waterproof surface. Solar cell modules measuring 4’ by 8’ are then heat-weld bonded to the surface, creating a unified roofing system with built-in solar cells.

“We were looking to replace our roof, wanted to lower energy costs for our tenants, and were interested in becoming an early adopter of a renewable energy source for future cost savings. So we not only got a new roof, but we also simultaneously got a new solar power system," said Savoy Commercial Properties Vice President of Operations Jeffrey Brueckner
