900 Main represents Redside’s first official high-performance, green building effort. The company had been in business just two years when it purchased the former Clackamas County Commissioners building in Downtown Oregon City. Built in 1917, it was home to the city’s first auto dealer. Redside converted the nearly 100-year-old structure into two levels of retail and office space. Redside incorporated a closed-loop, water-cooled, energy-efficient HVAC system for Subway that recaptures the restaurant oven’s heat output and redistributes it throughout the building to other tenants. Cool air generated from other space in the building is recycled to cool Subway’s kitchen. The building also includes energy-efficient lighting, operable windows, carpet with recycled fibers and wheat board cabinetry. Redside sold the facility to Oregon City investors in 2006.
