The National Building Code of Canada is the model building code of Canada. It is issued by National Research Council Canada.〔(NRC Website )〕 As a model code, it has no legal status until it is adopted by a jurisdiction that regulates construction. ==History== The Constitution of Canada includes the regulation of building construction as a provincial responsibility. In a few cases, municipalities have been given the historic right of writing their own building code. In the early years of regulating building construction, this caused a patchwork of building codes across Canada. In 1941, the federal government of Canada published the first National Building Code. This was adopted by the various provinces and municipalities in Canada during the next 20 years. On 1 August 1947, the Division of Building Research, later named the Institute for Research in Construction (NRC-IRC), was established to provide a research service to the construction industry and to help ensure affordable and safe housing for a growing population of Canadians. Its founding head was Robert Legget. The new organization was also given the mandate to lead the development of the National Building Code of Canada. Since then, NRC-IRC has grown to encompass emergent areas of research in support of the Canadian construction sector.〔(archive.nrc-cnrc.gc.ca: "NRC Institute for Research in Construction" )〕 Early photographs of activities are available in the archives.〔(dr-dn.cisti-icist.nrc-cnrc.gc.ca: "Pictures: Division of Building Research" )〕 The Northern Research Program was housed at the Division of Building Research over the period from 1950 to 1986,〔(cgs.ca: "Information and Location for Archival Records" )〕 and information gleaned from the Building Materials Section in York Redoubt made its way into the Code.〔(collections.mun.ca: "National Research Council of Canada, Division of Building Research, Building Materials Section" )〕 Since 1960, there has been a revised document about every five years up to 1995. The 2000 edition of the building code was supposed to be an objective or performance-based building. However, this took considerably longer to write than foreseen and the next edition of the National Building Code of Canada was not published until 2005. The 2010 National Model Construction Codes was published on 29 November 2010.〔(nrc-cnrc.gc.ca: )〕 and the National Building Code of Canada 2010 incorporates energy efficiency requirements.〔(nrc-cnrc.gc.ca: "National Building Code of Canada 2010" )〕 The first National Farm Building Code of Canada (NFBC) was first published in 1960. The Model National Energy Codes for Buildings and Houses were first published in 1997.〔 The Historical National Construction Codes on-line in PDF format is a single collection provided by the NRC of the English and French editions of all Code documents published between 1941 and 1998.〔(nrc-cnrc.gc.ca: "Historical Editions of the National Construction Codes (1941-1998)" )〕 On behalf of the Canadian Commission on Building and Fire Codes (CCBFC) the National Research Council (NRC) Canadian Codes Center publishes national model codes documents that set out minimum requirements relating to their scope and objectives.〔(nrc-cnrc.gc.ca: "Canadian Codes Centre" )〕 These include the National Building Code, the National Fire Code, the National Plumbing Code, the National Energy Code of Canada for Buildings (NECB) and other documents. The Canadian Standards Association (CSA) publishes other model codes that address electrical, gas and elevator systems. Requirements on the specification of structural wood products and wood building systems is set forth in the National Building Code which is concerned with health, safety, accessibility and the protection of buildings from fire or structural damage. The Code applies mainly to new construction, but also aspects of demolition, relocation, renovation and change of building use. The current NBCC was published in 2010, and is usually updated on a five-year cycle. The next update is expected in 2015.〔(cwc.ca: "Building Code - Canada’s National Code System" )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「National Building Code of Canada」の詳細全文を読む スポンサード リンク
