9.36 Energy Efficiency for Housing and Small Buildings

The new MBC Section 9.36 “Energy Efficiency” will apply to Part 9 buildings starting April 1, 2016. “Part 9 Buildings” under the MBC, applies to smaller buildings, including houses. The MECB may apply to some of the larger Part 9 buildings under Section 9.36.

Manitoba Energy Code for Buildings (MECB)

On December 1, 2014, the 2011 National Energy Code for Buildings becomes effective in Manitoba via provincial Regulation 213/2013.  It is known as the Manitoba Energy Code for Buildings (MECB). These new efficiency standards affect building envelope, lighting, heating, ventilation, air-conditioning, water heating, and electrical systems and, as per MECB Article, will apply to construction of new buildings and additions governed under Part 3 of the Manitoba Building Code.

For more information, read Bulletin – OFC 14-006 – Adoption of the National Energy Code for Buildings.

Please read the OFC’s list of to Frequently Asked Questions about the MECB for information on the intent, application and implications of the MECB for design professionals and the public.

Coordinating Registered Professional (CRP)

The OFC is enforcing the MECB through a Letter of Assurance and a Letter of Certification from a MECB Coordinating Registered Professional.
A MECB Coordinating Registered Professional must be:

  • A registered member of the Engineers and Geoscientists Manitoba (EGM), authorized to practice engineering in the Province of Manitoba and skilled in the appropriate area of work concerned; or
  • A registered member of the Manitoba Association of Architects (MAA), authorized to practice architecture in the Province of Manitoba.

The MECB Coordinating Registered Professional shall:

  • Ascertain which disciplines relating to the MECB are required and which registered professionals , must be retained;
  • Ensure the design requirements are coordinated between the registered professionals and comply with the applicable provisions of the MECB;
  • Complete a Letter of Assurance and a Letter of Certification.  In cases of a base building application, an additional Letter of Certification will be required for each initial tenant improvement.
  • Ensure the Compliance Checklist is completed, retained as a record for 7 years, and be available in the event of an audit. It is also required that a final copy of the Checklist be issued to the building owner.
  • Ensure the field reviews are coordinated between the registered professionals;
  • Certify that the construction substantially complies with the applicable provisions of the MECB;
  • Submit a Letter of Certification under seal at the completion of construction and prior to final occupancy.

Forms for Coordinating Registered Professionals (CRP)

Note: In submitting the Letter of Certification, the coordinating registered professional is not responsible for ensuring the compliance of design or construction with respect to the MECB for those aspects which are the responsibility of other professionals under seal and, as such, is entitled to reasonably rely on Letters of Assurance and Certification required by the OFC to be submitted by registered professionals and/or other statements provided by other professionals pertaining to the design and construction of the project.

Enforcement and Compliance Tools

  1. Compliance Checklist
  2. Part 4 Lighting Trade-off Compliance Tool - allows you to demonstrate compliance with the NECB 2011 using the trade-off path for Lighting (NECB Part 4)
  3. Part 5 HVAC and Part 6 DHW Trade-off Path Compliance Tool - allows you to demonstrate compliance with NECB 2011 using the trade-off path for HVAC and Service Water Heating.


  • These tools contains macros which may be blocked by your computer, after opening the tool, click on “Options” and “Enable All Macros” to allow the tool to function properly.
  • The tool was created by NRC to work with a PC platform using the Microsoft Excel. Those using other computer platforms (i.e., Macintosh or MAC) will require a copy of Microsoft Excel compatible with their computer to use the tool.


CAN-QUEST is a Canadian adaptation of eQUEST, the popular U.S. building energy simulation software. It builds upon eQUEST 3.62x and includes complete Canadian weather data, support for metric and imperial units, and English and French language interfaces.

CAN-QUEST can be used to demonstrate performance path compliance with the National Energy Code of Canada for Buildings 2011 (NECB 2011) and to support the design of high performance commercial and institutional buildings. CAN-QUEST is recognized as the Canadian building energy simulation tool for modelling whole-building energy performance and compliance with the NECB 2011.

CAN-QUEST includes many improvements over earlier building energy modelling software tools, including advanced two- and three-dimensional graphical representation of a building’s geometry and parametric runs to quickly assess different energy efficient designs. In addition, CAN-QUEST supports technologies such as photovoltaics, ground source heat pumps, co-generation, thermal storage and new heating, ventilation and air conditioning system types.
