• The NECB 2011 applies to all buildings covered
by Sentence 1.3.3.2 (1) of the MBC and also
includes additions.
• It does not cover Farm Buildings, temporary
buildings or construction camps.

Building Location Zones
• Based on Heating Degree Days (HDD) of
Building Location
• As presented in Appendix C , Climatic and
Seismic Information NBCC
• Manitoba is split into 3 Zones
– Southern MB is 7A (5000 to 5999 HDD)
– Central MB is 7B (6000 to 6999 HDD)
– Northern MB is 8 (≥ 7000 HDD)
OFFICE OF THE FIRE COMMISSIONER
MECB Definitions (Div A - 1.4.1.2)
• There are new 47 definitions, page 1-3, for

MECB Compliance
• Three main options:
1. Prescriptive path
•
•
Alternative solutions are also acceptable
Within Parts 3 to 7
2. Trade off path
•
Within Parts 3 to 6
–
Simple Trade off or Detailed Trade off
3. Performance Path
•
Part 8

MECB Compliance
The OFCs stance on enforcing the MECB is
that the design professional will take full
responsibility for the design and certification that
the energy efficiency of the building meets the
design.
Our staff will receive compliance forms and
Assurance and Summaries of professional
design forms.
