The National Research Council develops the national building codes in Canada. The codes are put together based on reviews and recommendations from various standing committees. These committees are made up of professionals in various fields who are invited to participate. 5
Model National Codes are revised on a 5 year cycle. On November 1, 2015 the 2015 National building code and National Energy code for buildings ( over 3 stories) is released. These codes are not legislated in each province until the local provincial government adopts them. This can be with or without changes. Typically the provincial codes are adopted 2 years after the release of eth national codes. There are many disciplines including fire, plumbing, electrical, building and others. Once the code is enacted, there is usually a 6 month grace period to adopt the new code requirements. 6
The Building Technical Council is the Alberta provincial committee that takes the national codes and make recommendations for adoption in Alberta. They do a public consultation and ask fro input from stakeholders such as builders, associations, manufacturers and others. They make a final recommendation to Alberta Municipal Affairs who are the provincial department responsible for codes. These changes are then adopted under the Safety Codes Act to become law. The National Research Council then prints and makes copies available for purchase. 7
The 2014 Alberta Building Code became enforceable May 1, 2015 with the grace period ending November 1, 2015. The entire document is enacted, except the new energy efficiency portion of Part 9.36, which is enforceable May 1 2016 and the grace period ends November 1, 2016. 8

The Safety Codes Act is the legislation that makes the actual code law. It list all stakeholders and their responsibilities regarding codes and compliance with these codes. 10
The Safety Codes Act lists the parties responsible for meeting code compliance. These include the builder/designer, manufacturers, vendors, contractors and others who do actual work on the building. They are all tasked with equal responsibility to enure compliance. Therefore the liabilty cannot be transferred to others to comply to code requirements. That means the entire group must work as a team to ensure compliance. 11
The building code is made up of 11 parts. Parts 1&2 cover definitions and clarify compliance options. Part 7 is health and Part 8 is demolition. These 4 parts apply to all buildings. Part 9 is less than 600 m2 in area including mulit family and single family dwellings. It can also apply to Part 3 buildings in some cases. Part 3 refers to large buildings and deals with fire and accessibility. Part 4 is structural, part 5 is environmental seperations and art 6 is HVAC. Some of tehse can also apply to Part 9 in cases where the occupancy and special circumstances relates to these specific aspects beyond Part 9 items. 12

Termite protection is only applicable to the SE corner of Alberta. The map is unclear as to the exact boundaries so contact your AHJ ( Authority Having Jurisdiction) if you are in these areas. ( Medicine Hat & Lethbridge). 15
Termite protection includes wood in contact with the ground, retaining walls, structural lumber etc. These must be treated with a termite resistant treatment. Inspection access is also required to visually inspect the foundation and under crawlspaces to assess potential for termite infestations. We recommend contacting your AHJ ( Authority Having Jurisdiction) to verify compliance options. 16
17
The exiting requirement for smoke alarm and carbon monoxide detectors remains, with one addition. All bedrooms must contain smoke alarms ( detectors). Smoke alarms must have battery backup and nusance button to silence in event of non fire smoke ( burnt toast) 18
19
The appendix of Part 9 provides great graphics explain the location of smoke alarms. 20
21
Split levels would be leveled to look like 2 story buildings. Rather than treating eth structure as a 6 storey building. 22
No change in the current Carbon Monoxide detector other than when a secondary suite is added. The requirement is to alarm the main dwelling and secondary suite together at the same time throughout the building. 23

Spatial Separations is separated in Part 9 buildings and houses Houses meaning single family and side by townhouses 27
Existing fire protection definitions have not changed 28
Added definitions explain what a FIRESTOP and a FIREBLOCK is and where these are required 29
Limiting distances have not changed. The HIRF ( High Intensity Residential Fires) requirements remain. The clarification relates to the sentence discussing limiting distance if the fire department takes longer than 10 minutes to arrive and set up to begin fire fighting more than 10% of the time they are called. This should be discussed with your local AHJ ( Authority Having Jurisdiction) 30
The effect of the 10 minute rule is the reduction in the limiting distance to half. In other words, the fire protection requirements will increase. This should be discussed with your local AHJ ( Authority Having Jurisdiction) 31

New compliance options for fire rated assembly components Walls and floors 36
Commissioning of any portion of the fire protections systems ( alarms, sprinklers, etc) must be done as a system, rather than as individual components. 37
Current exit sign requirements do not change what changes is the type of signage. The new signage is green and in pictogram format. They can be either electrical or self illuminating. This applies to all exit signage both in part 9 and part 3 buildings. 38
Egress notes some just moved location some are updated. 39
Window wells must be a minimum of 760 mm deep from the egress point. If the window open s outward you must add the window width when fully open to the 760 mm window well depth. CITY OF CALGARY Bi Law The current bylaw limiting window wells to 600mm is currently under review. This should be discussed with your local AHJ ( Authority Having Jurisdiction) 40
Resistance to Lateral window loads has been added to part 9.23 ( framing) section of the code. If your area is below the.80 kpa, this will not impact current construction if you continue to apply sheathing ( OSB, Plywood, Exterior Gypsum) to the exterior surface of walls and sheathing ( drywall) to interior surfaces of the walls. This is the most common construction. If you are between.80 and 1.2 Kpa you will have to apply the requirements noted in the next few slides. The main ones being diagonal roof sheathing, increase nailing pattern and Braced Wall Band. This is a direct connection form foundation to roof trusses. There only appears to be 2areas are affected by this PINCHER CREEK & COWLEY Above 1.2 kpa must be Part 4 designed 41

Seconday suites are a new definition. They must meet the bylaw requirements for the municipality i.e. likely falling under R 2 zoning. They apply to a suite that is added to a residence where the suite remains under the same title as the main residence. The new definition will allow smaller and tighter spaces to be used for secondary suites without having to meet the code requirements of the main dwelling 49

Where a fire separation extends above the roof, there is a potential fro drifting of snow, similar to the effect of a snow fence. Hence there is an increased potential for heavier snow loads on either side of these separation walls. This must be taken into consideration when doing snow load calculations. 53

Carbon monoxide detector locations when building Part 3 buildings is in Part 6. Mechanical ventilation definition updated no longer allowed to used unsealed or aspirating ventilation appliances. 67
Verify with your local AHJ ( Authority Having Jurisdiction). Old standard for plumbing was minimum 45C to maximum 60 C No longer require window screens to meet occupancy ( final inspection) requirements. 68
No change fro multi family multiple dwelling single attic access buildings. Single family can be reduce as shown 69
The first portion of part 9.25 contains minimum insulation levels up until May 1, 2016 ( enforceable after November 1, 2016) 70

This garage has a level floor, therefore potential fro gases to move into lower level of dwelling ( living space) at stairs. Under new code, a curb would be required to prevent air from going down these stairs, or the entire floor must be sloped to the front main overhead door 79
