Construction process: The contractor’s Waste Management plan minimised waste from con- struction materials. The disposal of all waste material generated has been tracked throughout the construction process — approximately 85% of waste has been diverted from landfill. Strict erosion and sedimentation control measures were followed throughout the construction process. Prevention of damage to the ex- isting shoreline and marine habitat was an absolute priority for Parks Canada. During construction, storm water was prevented from running offsite into the ocean. Silt-laden water resulting from construction ac- tivity was contained against the shore by a marine silt fence, a floating boom with a weighted curtain below to catch the silt. A minor amount of contaminated material was discovered on the site and removed in accordance with federal standards and procedures. During construction, an Indoor Air Quality Management Plan was de- veloped to give guidelines to the contractor on acceptable construction procedures such as ensuring that ventilation system components were kept clean and materials were protected from the weather. After construction was completed, the building was flushed out to help remove contaminants in the air. Materials and Resources: There has been an emphatic use of local and regional materials, including concrete floors and walls, glulam columns and beams, wood framing for all walls and partitions, Western Red Cedar siding and Douglas fir decking. Another criterion in the selection of products to be used was their re- cycled content: the percentage of recycled material exceeds 30% of total material costs. Materials used with recycled content include fly ash, which replaces some of the cement in the concrete, steel (varies from 25-95%), thermal insulation (9-40%), millwork panel products (80%), carpet tile (35%), aluminum frames (60%) and gypsum wall board (17%). Interior finishes and materials, including furniture, were chosen based on low VOC emission levels, durability and cost. The facility manager has developed a policy which allows only the use of green housekeeping products and procedures. Emissions: The energy consumption for the new building is expected to be 75% less than a Model National Energy Code Reference building. A com- puter simulation of the building systems’ energy use was used in the design process. This level of performance will result in a reduction of greenhouse gas emissions by 32.3 tonnes annually.
