There were only limited opportunities to reuse material on site. One exception was the stair rail caps, made from old floor joists. Other construction debris was hauled to a local recycling center.
The LEED process includes an initial plan review, in-progress inspections, and a final blower door and duct leakage tests. LEED takes a broad view of a building’s environmental impact and gives points for items that range from energy and water efficiency, to the types of materials used, to job site recycling and the availability of public transportation. MC3 took advantage of all of these.
An Energy Star rating is a bare minimum for LEED, and the goal for Bridgeview was to go well above that minimum with a well-insulated, airtight building envelope and high-efficiency HVAC systems. Exterior walls were framed with metal studs, held a few inches away from the brick wall to create a thermal break, and the entire cavity filled with wet blown cellulose insulation. The bottom plates of all walls were caulked and sealed. Window openings were fitted with high-efficiency Pella units. Each condo got its own 95% efficient Carrier gas furnace with a high-SEER cooling coil.
According to Alice Emmons, the project’s LEED consultant, MC3 took great pains to minimize landfill waste. “All the packaging was recycled. They even recycled the wrappers from workers’ lunches,” she says. Some of the old lumber found in the building—mostly floor joists that needed to be replaced—was de-nailed and milled for railings and other finish details on the third-floor unit. Some of the old bricks were also used for interior partitions. The rest of the torn-out materials were brought to a local recycling center.
