6 Background The Government introduced technical provisions into building codes to increase energy efficiency in the construction of buildings. Section adds requirements for Building Envelope components (windows, doors, Exterior walls and ceilings), HVAC (heating, ventilation and air conditioning) and Service Water Heating (domestic hot water). Section Energy Efficiency has been part of the 2014 Alberta Building code since its implementation May 1, An 18 month transition period was provided to allow window manufacturers, mechanical system suppliers, designers and builders to put into production and adapt to the new requirements. Effective November 1, 2016 permits applications must confirm to the requirements of the ABC 9.36, or National Energy Code for Buildings 2011; subject to the exemptions noted below. Application: Energy Efficiency (Note; can use NECB (National Energy Codes for Buildings) for any building 9.36 applies to) Group C (600 m2 or less, 3 stories or less with common spaces not exceeding 20% of the buildings floor space) Group D, E and F3 (total floor area 300 m2 or less excluding parking garages that serve residential occupancies) NECB must be used for all other occupancies and building areas/heights not noted above and covered by the ABC (Alberta Building Code). Notes: 1. Same Alberta Building Code exemptions for farm buildings, utility towers Only applies to new construction and new additions. 3. Will apply to renovations in the future for buildings built under the energy codes. 4. Only applies to conditioned space; exemptions include seasonally heated buildings, storage and parking garages, small service buildings or service rooms and unconditioned spaces in buildings. However, note that, where a building envelope assembly of an exempted building is adjacent to a conditioned space, this assembly must meet the requirements of Section Requirements for Building Permit Submission: 1. Prescriptive requirements of the Alberta Building Code; a. Completed application as required by Superior Safety Codes and your local Municipality b. Complete set of drawings/plans with details of all wall, floor, ceiling, cantilever building envelope assemblies showing the components added to achieve the required effective thermal resistance requirements. c. U-Values and Energy Efficiency Ratings of all windows, doors and skylights should be noted on the plans. d. Performance Requirements for all HVAC and Service Water Heating equipment to be shown on the plans. 2. Trade-off Options; a. Detailed calculations are required in compliance the Alberta Building Code (see page 9); in addition to the requirements of 1 above. 3. Energy Performance Compliance; a. Completed application as required by Superior Safety Codes and your local Municipality b. Required information as per Article of the Alberta Building code (see pages 16 & 17). 3 P a g e
