Demonstrating the Benefits of Life Cycle Assessment

The goal of green design is to achieve sustainability by designing and building structures that use less energy, water and materials, and minimize impacts on human health and the environment. Life cycle assessment (LCA) supports this by providing an assessment of the resource consumption — including energy, emissions and waste — throughout the building’s life. It means adding up the inputs and outputs for every framing member, panel, fastener, finish material,coating and other materials used in the building.

LEED V4 Shifts Emphasis of Environmentally-Friendly Construction Material to Wood

A report published this month by Dovetail Partners analyzes how LEED V4 emphasizes wood as the most environmentally-friendly construction material and will bring increased incorporation of green building concepts into buildings of all kinds. Buildings constructed in the future will be significantly more energy efficient than today and more attention will be given to minimizing environmental impacts wherever possible using science-based tools to identify lowest impact alternatives. In this environment, wood products can become the building materials of choice.

City of Vancouver Advances Toward Zero-Emission Green Buildings

An 85-unit six-storey wood apartment is being built on the corner of Skeena and East Hastings streets in Vancouver. When complete it will be the largest Passive House building in Canada.

Across B.C., buildings account for 11 percent of greenhouse-gas emissions, according to a report by the provincial climate leadership team. The report cited Brusselswhich went from amongst the worst in Europe to amongst the best over an eight-year periodto suggest that B.C. could reduce emissions in this sector by 50 percent by 2030.
