COVID-19 Updates: State of public health emergency declared.
Improving energy efficiency standards for building construction codes supports greenhouse gas emissions reduction and reduces the demand on Alberta's energy resources.

Guidance for energy codes
Municipal Affairs has developed a user guide for section 9.36 of the Alberta Building Code (ABC) 2014 in consultation with municipalities, industry and safety codes officers. This information is designed to assist code users for compliance with both prescriptive and performance paths under section 9.36.
It provides code users with key considerations for submitting permit applications to the authority having jurisdiction, samples of a project summary and trade off calculations, clarification of code requirements for airtightness and checklists for energy code compliance under section 9.36 of the ABC.

The energy codes will deal with the following building components:
- building envelope – the separation between the interior and the exterior environments of a building, comprising of its exterior walls, roof, foundation and slab-on-ground
- lighting – includes interior and exterior lighting components and systems connected to the buildings electrical service
- HVAC – heating, ventilating and air conditioning covers items such as ducting and piping, controls, ventilation and related equipment
- service water heating – systems used for the supply of water for purposes other than space heating
Whether considering a large commercial complex or a single-family house, you will have several approaches to select from to suit the needs of the budget, location and the owner.
The expected energy performance characteristics for the building are met using a design prepared by a qualified professional. This approach offers the greatest possible design flexibility while still meeting energy efficiency goals, calculations usually verified by an approved software although not necessary.
Performance using simple trade-off
The expected energy performance characteristics for the various building elements are met. However, within each building element (for example, exterior fenestration), it is possible to 'trade-off' increased performance in one element for reduced performance in another (for example, increase wall insulation to allow more less efficient windows).
The expected energy performance characteristics for the various building elements are met by following the prescribed approach set out in the code. For example, following the prescribed level of thermal insulation and amount of windows for the region where the building is to be constructed.
Examples of increased energy efficiency requirements in Alberta's safety codes.
