The National Codes adopted about technical changes to enhance clarity, introduce new concepts, and expand existing requirements.

Ongoing uncertainty that can be quantified by various improvements to climate change models and their methodologies in codes and standards e. Historically, codes and standards to deal selectively with the growing uncertainty of have sometimes addressed changed uncertainties future climate conditions.

It is important to be or increased risks by adjusting their safety factors. This In spite of the uncertainties of the climate factor s could potentially accelerate the models, some options are available currently or incorporation of regularly updated climatic design under development to selectively consider growing values into codes and standards and optionally risks to infrastructure and to incorporate allow for additional increases in regional climate adaptation into design codes and standards.

Typically, These options for national codes and standards building codes and other infrastructure standards include: are slow to change and long and extensive peer- review processes are required before any changes 1. Increasing the safety or uncertainty factors used for design i. The first term could explicitly of climatic loads given evidence of likely update climatic design values for the most recent increases in risks over the lifespan of the climate observations and trends while the second structure Auld, a; Association of British term could account for projected climatic design Insurers, ; values that increase regionally over the typical 3.

For example, regionally specific Climate Change Adaptation The safety or uncertainty factors used in Factors could be used when comparison against codes and standards offer one means to reflect climate trends indicates that updated and growing uncertainties in climatic conditions over increased design values are needed or when it is roads, pipelines, water structures and mining likely that the risks from changing climate ponds and it is clear that adaptation solutions are conditions will increase over time.

Some of the most rapid climate changes on earth A relatively new option for incorporating climate have been observed in the Canadian and U. Climate is the risks over the lifespan of a structure. In one principal factor controlling the formation and probabilistic approach to limit states design under persistence of permafrost, with ground development by Fenton and Soleymani , a temperatures and permafrost active layer depths new methodology for climate change adaptation directly linked to time averaged mean air involves a re-work of climatic factored design temperatures.

Such an unprecedented in the last years ACIA, , approach has the advantage of capturing the while over the past 15 years, mean annual air underlying uncertainty in the evolution of climatic temperatures have risen more rapidly in the loads over the lifetime of the structure. The eastern Arctic than anywhere else in Canada approach also can be modified to include the Vincent and Mekis, updated in ; CSA, potential of increasingly severe extreme events.

The approach by Fenton and construction, and maintenance in regions where Soleymani has the potential to provide construction and operating costs are already high valuable insight into the impacts of changing due to distances, isolation and extremely cold climatic design loads on structural reliability using environments NRTEE, ; CSA, In the limit-states design approach.

The challenge particular, infrastructure systems in permafrost will lie in providing an appropriate set of climate have depended critically in past on the stability of change projections of extremes i. But, with given the limitations and uncertainties in the climate warming, a variety of infrastructure types climate change models in dealing with extremes at in these latitudes are increasingly vulnerable to finer scale resolutions.

Recognizing the valued information in forensic Current research at Environment Canada is analyses, Environment Canada is in the process considering the climatic implications of a limit- states design approach that could be applied to of developing a climate and infrastructure impacts tornadoes.

Efforts are also underway to update, database to complement existing extremes revise and consolidate tornado incident reports analyses of high impact climate events in Canada. These events span all seasons and 6. All of these While the technical provisions of the current high impact wind events have been collected and edition of the National Building Code of Canada compiled from numerous sources e.

The associated with various high impact thresholds, commentary also highlighted the need for careful identifying regional differences in vulnerability, and consideration of climate variability in estimated understanding safety thresholds needing greater values of climatic design loads.

The impacts information in general The historical climatic design values in the NBCC are being updated and improved through can prove to be invaluable and complementary to more rigorous quality control of the climate data, the statistical extreme value analyses that are improved analysis procedures and incorporation of traditionally used in developing climatic design forensics studies and impacts databases see criteria for building codes and standards.

Climate extremes careful monitoring of climate trends and regular data that have been quality control removed from updates to design values. Similar thresholds have realistically incorporate climate change adaptation been studied for other types of hazards e.

This paper has provided an overview of guidance on the consequences of threshold the different approaches that can be considered exceedance. These threshold studies can be used for development of adaptation solutions: top-down to implement a number of disaster mitigation and scenario based approaches, vulnerability-based management strategies; e.

All of the approaches acknowledge that warning systems ; guidance for long term stationary climate conditions will not apply in the mitigation measures i. However, the path forward in preparedness and response i. What is clear is that the cost of inaction and failure to adapt to climate change realities will lead 6. Change and Vulnerability Studies Projected increases in extreme events from climate change will increase the risks of In support of stakeholders, Environment catastrophic failure in the urban environment as Canada has developed an interface that structures are strained beyond their design limits.

Building Code Interpretations - interpretations on Code items 3. Building Code Bulletins - additional explanatory information on Code items or general Code topics British Columbia The British Columbia Building Code[17] is based on the core concepts of the National Building Code with some variations specific to the province.

The introduction of a provincial Building Code Act and a provincial Building Code addressed this problem by providing for uniform construction standards across Ontario. Whereas the Construction Code applies to plan and estimate designers architects, engineers, technologists and contractors, the Safety Code is intended for owners of buildings, equipment, and facilities.

These two codes are adopted chapter by chapter and are progressively replacing the seven laws and thirty-odd regulations that were previously in effect. The goal of this process is, obviously, to simplify regulations, but also to better define the responsibilities of owners and construction professionals. In force since November 7, The Code de construction du Quebec[27] Consisting of the National Construction Code — , amended and includes Part 10 for existing buildings.

The Quebec Code de Construction is not compulsory in the province. Municipalities have the option of adopting the code of their choice, with or without modifications. In fact, many municipalities do not have any building code officially in effect. Manitoba,[31] New Brunswick,[32] and Saskatchewan[33] have adopted the National Building Code as regulations under provincial acts. Federal jurisdiction For most construction under federal jurisdiction the National Building Code of Canada is the applicable Code.

Property under federal jurisdiction includes military bases, federal government land and airports. Content The intent of the Building Code is to detail the minimum provisions acceptable to maintain the safety of buildings, with specific regard to public health, fire protection, accessibility and structural sufficiency. It is not a textbook for building design. The Building Code concerns construction, renovation, and demolition.

The Code sets out technical requirements for the aforementioned project types and does not pertain to existing buildings. The National Building Code is split into 9 parts. Houses and certain other small buildings less than 3 storeys high and m2 are considered "Part 9 Buildings" and Part 9 drives the majority of the code requirements, with references to other parts where the scope of Part 9 is exceeded.

Larger buildings are considered "Part 3 buildings" and parts 1 through 8 apply. Part 3 is the largest and most complicated part of the building code.
