At Local Practice we recognize that an important aspect of sustainability is achieving recognition for benchmarked goals. Environmental rating systems have become an industry-wide architectural design standard for establishing social and ecological benchmarks, and are proving to be reliable tools for the assessment of a built project’s on- going performance. Of all the various options, four have emerged as having the most relevance in the Cascadia Region and Western Canada: LEED, the Living Building Challenge, Envision and the Passive House rating system. Our team has completed over 25 projects utilizing these rating systems and many more currently on the boards. We are also aware of and are familiar with other systems, such as product life cycle analysis, Cradle2Cradle product certification, and the Sustainable Sites certification.
