There are 2 energy components to the 2014 Alberta Building Code.
Section 9.36 covers New houses and small buildings (under 300 m2)
NECB ( National Energy Code for Buildings) covers Part 3 buildings as well as Assembly, Care & Detention and Industrial buildings, which may be under 300 m2.
You can only follow one set of code requirements.
However, under each code, there are generally optional compliance pathways.
1. Prescriptive - with and without heat recovery
2. Simple trade off (only within the building envelope)
3. Performance - Energy model required
So which path do you choose
Really depends on what your building.
Most cost effective: Performance
Most flexibility: Performance
- Addition where existing furnace is used
- Addition where new furnace is added, but used to heat existing home and new addition
- Renovation where existing furnace is used
- Main floor strip out without improving the existing basement and/or mechanical, ventilation / windows.
Simple trade off (Prescriptive)
We can upgrade one area to reduce another area. I.E. if they need to use R-24 in the walls, and they are adding windows, we can use triple glaze windows to reduce that to R-22 walls
- Addition which has its own new furnace, DHW and ventilation system
- Complete strip out – new insulation, windows, mechanical
To comply with performance route
- Must be installing new windows
- Must installing new Furnace
- Above Grade Must upgrade insulation in walls & Attic (existing exterior cladding may remain)
- Below grade Must be upgrading insulation in walls
