MMA Update

Potential Changes to Ontario’s Building Code Ontario’s Building Code is typically reviewed every five to seven years. In addition, interim amendments to the Building Code are sometimes made between editions to reflect technological advancements, support government priorities and address emerging issues. This year, the Ministry of Municipal Affairs is seeking input from the public and industry stakeholders on changes being considered to the Building Code. This consultation will occur in two phases.

6

MMA Update continued...

The first phase, October 21 to December 20, will include proposed interim amendments that support the Long-Term Affordable Housing Strategy update as well as changes that would form the next edition of the Building Code. In addition, they are seeking advice on preliminary changes the government should consider to improve energy efficiency and water conservation that could be implemented quickly and over time.

7

MMA Update continued...

The second phase, The consultation will seek input on proposed requirements to support the implementation of the government’s Climate Change Action Plan.

8

MMA Update continued...

How to participate The Ministry of Municipal Affairs want to hear your comments and feedback on the proposed Building Code changes. Closing date: December 20, 2016 For more info please visit

Applications continued…

Online Permits continued:

• All revisions shall be uploaded to “My Permits” for

the affected permit . We receive notification of the new attachments automatically, no separate email is required.

• Decks or new finished areas (not previously

included in the issued permit) are not revisions. These type of items are new and separate applications.

18

Applications continued…

Online Permits continued:

SB-12

Justin Massecar Municipal Building Official

26

Overview

• Applicable for permits applied for AFTER

December 31, 2016.

• Reminder: Provide calculations to determine the %
• f the basement which is above grade on walkout
• lots. [3.1.1.1.(10)]
• Reminder: When calculating Gross Wall Area for

any townhouse type building the “party walls” are to used in the calculation [3.1.1.1.(7) to (9)]

• Reminder: Hot supply pipe to be insulated for first

8’ of pipe after water tank. [Div. B, 12.3.1.4.]

27

Overview

• Reminder: Correct window labeling, as required

currently, is important.

28

Heat Recovery Ventilators

• Heat Recovery Ventilators required for all

ventilation systems serving dwelling units. [3.1.1.1.(16)]

• Review HRV efficiency. The minimum Sensible

Recovery Efficiency (SRE) measured at 0°C and 30L/s flow rate. Varies from 65%-81% (75% likely most common). [3.1.1.1.(19)]

• HRV information to be shown on the mechanical

summary form submitted with the heat loss calculations.

29

Drain Water Heat Recovery

• Drain Water Heat Recovery units required

in all dwelling units. [3.1.1.12.(1)]

• Must be connected to at least two

showers, if more than two showers. [3.1.1.12.(1)]

• Cold in the bottom, hot out the top.

[3.1.1.12.(6)(b)]

• Installed in a conditioned space

[3.1.1.12.(6)(d)], downstream of any water softener. [3.1.1.12.(6)(c)]

• Efficiency shall be not less than 42%

[3.1.1.12.(5)]

30

Trade-offs Within Packages

• Incentives are provided for increasing air tightness

in dwellings. Tables for one or two substitutions per

• dwelling. [3.1.1.4]

31

Trade-offs Continued…

• Must be verified by blower door test. [3.1.1.4.(2)]
• Report is required to be completed by the energy

consultant.

• Provide to inspector prior to occupancy inspection.
• Report to include the Air Changes per Hour

(ACH)(most common) or the Normalised Leakage Rate (NLA). [3.1.1.4.A]

32

Insulation

• In addition to increased R values, packages include
• ptions for effective R-values, and max. total U-

value.

33

Insulation continued…

• Reducing thermal bridging by

adding continuous insulation (ci) to most packages.

• Take advantage of advanced

framing techniques, right sized lintels, etc. to reduce amount of lumber within wall assembly.

34

Insulation continued…

• Insulation values must be either all nominal or all

effective, can’t switch between the two.

• If your design includes a tall wall, likely won’t

achieve effective R value.

• When right sizing lintels, show correct lintel size at

each openings, not with a generic note or chart.

35

Insulation continued…

• We require calculations for effective R value, if

selecting this option, to be shown on drawings for plans review.

• National Research Council of Canada “Tables for

Calculating Effective Thermal Resistances of Opaque Assemblies” [Appendix A 1.3.2.1.(2)] www.nrcan.gc.ca/energy/efficiency/housing/new- homes/energy-star/14176

36

Windows

• Specific windows or sliding glass doors permitted

to not meet the required U-value under a specific

• circumstance. [3.1.1.9.(5)]
• When a lower solar heat gain coefficient is

used due to it’s orientation (i.e.. South/West facing).

• Permitted, provided average thermal

performance of all windows/SGD is

• maintained. [3.1.1.9.(5)]
• Need to show on drawing U-values of windows, if

different

37

Basements

• R20 continuous insulation is typical (R20 wrap)
• Effective R value is an option to explore.
• Packages with both batt insulation and continuous

insulation are available.

• Stair opening dimensions will change when located

adjacent to foundation walls (R12 stud or R12 blanket wrap walls no longer an option)

• Watch out for protection of foamed plastics (i.e..

R5 rigid insulation can’t be protected with only 3.5” mineral wool batt, may have to substitute products)

38

Performance Compliance

• Similar methodology to existing.
• Updated list of software (See SB-12 Appendix).
• SB-12 changes are promoting the use energy

modelling.

• Opportunity to use performance, reduce attic

insulation, change efficiencies of mechanicals, provide for strategically placed windows, etc. could lead to better built houses, while controlling costs.

39

Performance Compliance

• Would need to model each house separately.
• NRCan, “Energy Star for New Homes Standard

Version 12.6, or,

• NRCan, “2012 R2000 Standard.”
