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 www.mah.gov.on.ca Ontario Building Code\Hot Topics\ Potential Changes to Ontario’s Building Code 9

Applications Online Permits: • Applications should be one attachment containing all the required information. • All drawing attachment(s) shall be original pdf and not scanned copied of the drawings. • Ensure any of the drawings being provided to you are not locked by your design professional. • When entering in the description of the permit for a new dwelling it is helpful to enter the model name the builder uses. 14
Applications continued… Online Permits continued: • Take advantage of the copy feature available. http://www.kitchener.ca/en/livinginkitchener/Build ingDivision_AnnualWorkshops.asp • Stacked Townhouses require one permit application per “bay” and include the list of unit number(s) in the description. 15
Applications continued… 16
Applications continued… 17
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: • Square footage is measured to the outside of exterior walls for all floors above grade. The areas for the stairs, open to below spaces are not to be omitted from this calculation. 19
Plans Examination • Engineered beams bearing on another beam, the bearing beam also requires to be designed by the engineer. • All beam sizes outside of the building code tables require Engineer review. 20
Plans Examination • Side entry doors requiring a landing that exceed 24” above grade will require the setback per our Zoning By-law (eg 1.2m). 21
Plans Examination • Any column, beam, or wall supporting a floor that has a fire resistance rating shall have the same rating as that floor above. Details need to be provided on the drawings showing how this is going to be achieved. • Indicate the number of risers required from the garage into the house on either the site grading plan or floor plans. 22
Code Requirements • Include a site plan and grading plan for all townhouse/stacked townhouse type developments. Setbacks to property lines and other buildings on the site are to be shown. • New grab bar details, effective January 1, 2017. 23
Code Requirements 24
Code Requirements • Provide Engineering when the width of the foundation between windows is less than the size of the window that portion of the wall is now considered laterally unsupported as per 9.15.4.3.(4). 25
SB-12 Justin Massecar Municipal Building Official 26
Overview • Applicable for permits applied for AFTER December 31, 2016. • Reminder: Provide calculations to determine the % of 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 options 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
