For 3 years, the rewriting of the new Building Code of Canada has been in the hands of specialists, and new very strict rules will come into force gradually from this year (2019).<\/p>\r\n\r\n\r\n\r\n
\r\nThe code will mainly target new construction, but it will also deal with the various aspects of demolition, relocation, renovation and changing the use of buildings.<\/p>\r\n
The current CNB was released in 2015 and is usually updated every five years. The next update is therefore scheduled for 2020.<\/p>\r\n<\/blockquote>\r\n\r\n\r\n\r\n
\u00a0<\/div>\r\n\r\n\r\n\r\nCNR is leading an initiative on climate resilient buildings and basic public infrastructure aimed at updating climate data, related climate loads and load combinations, as well as new climate resilience provisions that will be implemented. work in future versions of codes, standards and guides. including the National Building Code, the National Energy Code for Buildings – Canada and the Canadian Highway Bridge Design Code.<\/p>\r\n\r\n\r\n\r\n

\u00a0<\/div>\r\n\r\n\r\n\r\nThe National Research Council of Canada (NRC) says homes and highways across the country have been built according to weather models which are now obsolete due to climate change.<\/p>\r\n\r\n\r\n\r\n
New data on the collected climate changes will be used for the 2020 update of the the national building code and that of the construction of highways, which does not are not laws but serve as models for the provinces and municipalities.<\/p>\r\n\r\n\r\n\r\n
The aim is to adapt the national building code so that infrastructure can better withstand pressures from fires, floods and windstorms that will become more and more more frequent. Indeed, according to a report by the Canadian ministry of Environment released last week, Canada is warming twice faster than the rest of the planet.<\/p>\r\n\r\n\r\n\r\n

\u00a0<\/div>\r\n\r\n\r\n\r\nNew provisions for the certification of resistance of roofs to extreme weathering is planned for 2020.<\/p>\r\n\r\n\r\n\r\n

\u00a0<\/div>\r\n\r\n\r\n\r\nUpdates to improve mixtures of concrete for the pavement to alleviate pothole problems are also planned. For example, the City of Montreal should put them in place in 2021 following field trials.<\/p>\r\n\r\n\r\n\r\n

In addition, in order to take into account the strong winds associated climate change, new structural design rules for the buildings should be ready for adoption only in 2025. Changes are also expected on the calculation of road bridges in the same period.<\/p>\r\n\r\n\r\n\r\n

\u00a0<\/div>\r\n\r\n\r\n\r\nThe National Building Code and National Fire Code offer new home care facilities.

To increase the safety of openable windows, design changes less restrictive are proposed.<\/p>\r\n\r\n\r\n\r\n
