As an internationally recognized mark of excellence, LEED provides building owners and operators the tools they need to have an immediate and measurable impact on their buildings’ performance. The Canadian rating systems are an adaptation of the US Green Building Council's (USGBC) LEED Green Building Rating System, tailored specifically for Canadian climates, construction practices and regulations. The rating systems are adapted to the Canadian market through an inclusive process that engages CaGBC members, stakeholders and experts representing the various sectors of the Canadian industry.
LEED promotes a holistic approach to sustainability by recognizing performance in five key areas of human and environmental health, which include sustainable site development, water efficiency, energy efficiency, materials selection, indoor environmental quality. Credits and Prerequisites are organized into these five categories. LEED Certification is based on the total point score achieved in these five areas, following an independent review. 145 King Street West was certified with a Gold level of the award, on June 23, 2012.
