MECB Part 1 - Application

• 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.

• Generally , it does not cover small Part 9 buildings or single family dwellings.

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)

MECB Definitions (Div A - 1.4.1.2)

• There are new 47 definitions, page 1-3, for example:

Addition means any conditioned space that is added to an existing building that increased the buildings floor surface are by more than 10m².

As well as 3 new Manitoba specific definitions.

OFFICE OF THE FIRE COMMISSIONER Building Safety Section

MECB Definitions (Div A - 1.4.1.2)

Back-up System means a system installed for the sole purpose of operating if the primary system is out of service.

Temporary building means a building placed at a particular location for the period authorized by the authority having jurisdiction. If the building is not removed on or before the end of the authorized period, it is considered to be a new building for the purposes of this Code.

Fenestration means all building envelope assemblies, including their frames, that transfer visible light, such as windows, clerestories, skylights, translucent wall panels, glass block, transoms, sidelights, spandrels, overhead or swinging glass doors and glazed inserts in doors etc.

OFFICE OF THE FIRE COMMISSIONER Building Safety Section

MECB Part 3 – Building Envelope

3.2.2.3 – Thermal Characteristics of Fenestration– Requirements for Windows to be 2.0 in Zones 7A & B

and 1.6 in Zone 8.

OFFICE OF THE FIRE COMMISSIONER Building Safety Section

MECB Part 5 – HVAC

• 5.2.4.1(3) – Required Dampers– Air intakes and outlets serving HVAC systems

required to operate continuously under an enactment need not comply with Sentence 1.

Sentence 1 requires - Every duct or opening required to discharge air from a conditioned space and every air intake duct must have motorized damper.

OFFICE OF THE FIRE COMMISSIONER Building Safety Section

MECB Part 5 – HVAC

• 5.2.10.3 – Heat Recovery in Ice Arenas and Curling Rinks – Slight modification of the requirement for heat

recovery in these areas to state when an area of an ice rink or curling arena “is heated”, rather than “has a heating requirement”.

OFFICE OF THE FIRE COMMISSIONER Building Safety Unit

MECB Part 5 – HVAC

• 5.2.12 – Equipment Efficiency– This section consists of a table that covers the

efficiencies for packaged HVAC equipment.– For example it requires a AFUE of 84% for oil fired

boilers.

OFFICE OF THE FIRE COMMISSIONER Building Safety Section

MECB Part 6 – SWH

• 6.2.2 – Equipment Efficiency– This section consists of a table that covers the

efficiencies for SWH equipment.– Equipment not listed in the table shall be insulated to

a max U value of 0.45W/(m²·K)– MB Amendments have included a table to clarify the

standards which fixed the inputs, capacities and correct the standards listed for Gas Fired appliances.

OFFICE OF THE FIRE COMMISSIONER Building Safety Unit

MECB Part 6 – SWH

• 6.2.6 – Hot Service Water– Primary showerheads 6.6 L/min– Lavatories 5.7 L/min

OFFICE OF THE FIRE COMMISSIONER Building Safety Section

MECB Part 7 – Electrical Power Systems and Part 8 Performance Path

• No amendments

OFFICE OF THE FIRE COMMISSIONER Building Safety Section

MECB Compliance

Regardless of the compliance path chosen, compliance forms will have to be filled out by the design professional and then submitted to the AHJ.

OFFICE OF THE FIRE COMMISSIONER Building Safety Section

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

OFFICE OF THE FIRE COMMISSIONER Building Safety Section

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.

OFFICE OF THE FIRE COMMISSIONER Building Safety Unit

Section 9.36 – Energy Efficiency in Housing and Small Buildings

• This Section was released in December 2012 as a Revisions and Errata package to the 2010 NBC.

• It includes all of the energy efficiency requirements for Part 9 Houses and Small buildings.

OFFICE OF THE FIRE COMMISSIONER Building Safety Unit

Section 9.36 – Compliance

1. Prescriptive Path/Alternative Solutions

2. Simple Trade Off• Make slight modifications using the Simple Trade-Off

Method (e.g. trading reduced wall insulation for

increased attic insulation)

3. Performance

• Model the building and verify that its predicted energy

use is equal to or less than that of the same house

designed to the prescriptive requirements
