Description

The Island West Coast Developments Ltd. (IWCD) is a business established to provide sustainable building solutions. Their services include design-build, construction management for commercial, multi-residential, industrial, and other building projects on Vancouver Island. The company has a mission to initiate and construct sustainable buildings including green roofs (Fig. 10.12). Their projects strive to include sustainable stormwater management, low water, and energy use, low volatile materials, and energy-efficient buildings. Green roofs are a multi-benefit investment, and so IWCD wanted to pilot test an extensive green roof with native vegetation on their headquarters building. Based upon plant communities known to the Garry oak ecosystem, the extensive roof on their building has a variable depth substrate that ranges from 7.6 cm to 15 cm deep (3–6 in). The multi-sectioned green roofs are accessible to office workers on an observation deck. Grasses, forbs, and succulents were selected for the design. The LEED Gold-certified building was constructed in 2009, the green roof has green and flowering vegetation during the springtime and early summer. With no regular irrigation, however, the vegetation during the summer often becomes dormant, like the vegetation in the nearby Garry oak ecosystems.
