44、2 1Z783-12Deconstruction of buildings and their related parts0Introduction0.1 DeconstructionThis Standard deals with the deconstruction of buildings. Construction of buildings has a wide spectrum of direct and indirect effects on human health, communities, and the environment. According to CCA 81, i
45、n Canada approximately 40% of annual national resource expenditures can be attributed to the construction industry. While the reuse of the building should be considered as the first option, it is recognized that recovery of materials can be accomplished through demolition. Deconstruction during the
46、demolition phase facilitates the reuse of materials without further processing through recovery of materials, components, products, and systems at the end of a buildings life or when it is undergoing renovations or alterations.0.2 Reasons for deconstructionConstruction, renovation, and demolition wa
47、ste accounts for up to 25% of municipal solid waste measured by weight.* Resource planning and management of waste contribute significantly to the nature and extent of the environmental impacts.Great potential exists in the deconstruction of building components to contribute to sound stewardship and
48、 conservation of the environment. Direct and indirect environmental benefits can include(a) reduced stress on waste disposal sites, e.g., landfills;(b) reduced raw material use;(c) energy conservation in the raw material acquisition, manufacturing, and transportation phases; and(d) reduced greenhous
49、e gas emissions (see Annex A).A detailed description of potential benefits is provided in Annex D.*Taken from Statistics Canada (2002).0.3 Sustainable use of building stockThe following options should be considered for future use of building stock:(a) reuse of the building or space;(b) reuse of materials, components, products, or systems on site;(c) reuse of materials, components, products, or systems off site;(d) recycling of materials, components, products, or systems on site (e.g., chip wood for landscaping);(e) recycling of materials, components, pr
