LEED Canada for New Construction and Major Renovation (NC) 2009 is a green building measurement system designed for rating new and existing commercial, institutional, and high-rise residential buildings. It is based on accepted energy and environmental principles and strikes a balance between knowledge from established practices and emerging concepts.
It is a performance-oriented system where credits are earned for satisfying each criterion. It is separated into prerequisites that are mandatory to attain certification and optional credits that count towards the level of certification. The categories of the rating system are as follow:
• Sustainable Sites
• Water Efficiency
• Energy and Atmosphere
• Materials and Resources
• Indoor Environmental Quality
• Innovation in Design
• Regional Priority
In general these requirements include maintaining practices which ensure healthy indoor air quality as well as maximizing the use of durable, non-toxic, low-embodied energy, low-emitting, high recycled content, and local materials.
Materials and systems shall be selected to maximize energy efficiency for operation of the SUB throughout its service life.
Materials shall be selected that efficiently use resources such as energy, water, and component materials, that use less embodied energy to manufacture and that consider energy use over the life-cycle of a material including harvesting, mining, manufacturing, transport, installation, use, operation, recycling and disposal.
