SB 12 Update

• SB12 is the Energy Requirements for Part 9
  housing.
• It came into effect January 1st, 2012.
• SB12 refers to the Supplementary Guidelines, not
  the date of implementation. The date is a
  coincidence.
• SB12 was revised in the spring of 2013.
• The revisions came into effect on March 15th,
  2013, the same date it was signed by the
  Director.

SB 12 Update

• Supplementary Standard SB-12 to the 2006 Building
  Code Energy Efficiency for Housing has been
  amended to
• Clarify that the R-value referenced in the SB-12
  Tables for insulated concrete forms refers to the
  entire assembly
• Clarify that, for factory built modular homes
  manufactured before 2012, the SB-12 requirements
  do not apply
• Enable the use of drain water heat recovery units
  in conjunction with the compliance packages
  available in the prescriptive Tables
• Include other editorial changes, clarifications
  and new appendix notes.

SB 12 Update

• Notes to Table 2.1.1.2.A
• Except for notes (3) and (4), the values listed
  are minimum RSI-Values for the thermal insulation
  component only. RSI-Values are expressed in
  (m²K)/W.
• Same.
• Same.
• Compliance package L applies only to a building
  with ICF basement walls. Alternatively, any other
  compliance package except compliance package K,
  is permitted to be used for a building with ICF
  basement walls. The thermal resistance value of
  an ICF wall is the total thermal resistance of
  the entire wall assembly. (Was The thermal
  insulation value of an ICF wall is the sum of the
  insulation value on both sides of the walls.)
• This is a clarification for ICF insulation values.

  walls, windows or basement walls is reduced by
  applying
• Sentences (6) through (11), only the thermal
  performance of one of those building components
  is permitted to be
• reduced.
• This is a clarification as there were some
  designers / builders who were trying to apply
  multiple reductions. The original intent was to
  permit one reduction.

11
SB 12 Update

• (11) Where an HRV is only required for the
  purpose of meeting the energy efficiency
  requirements of a compliance package included in
  Table 2.1.1.2.A, the HRV may be omitted provided
  that a DWHR unit with a minimum efficiency of not
  less than 62 is installed in conformance with
  Article 2.1.1.11.
• Editorial Comment. As homes are required to be
  built with a greater tightness, Mechanical
  Ventilation will be of ever increasing
  importance. Indoor air quality and warranty
  issues may occur if inadequate ventilation is
  provided.

4/25/13

  connection is at the bottom of the unit,
• downstream of a water softener where a water
  softener is installed, and
• in a conditioned space or on the warm side of the
  dewpoint of the wall assembly.
• Except as required in Clauses 2.1.1.2.(10)(b) and
  2.1.1.3.(8)(a), (b) and (d), and Sentence
  2.1.1.2.(11), the minimum efficiency of the DWHR

14
SB 12 Update

• A-2.1.1.11.(4)(a) Drain Water Heat Recovery Units
  for Showers.
• For the purpose of the prescriptive trade off
  provisions in Subsection 2.1.1., the term all
  showers includes the case where there is only
  one shower in a dwelling unit.
• If there is only one shower it is required to be
  connected to a DWHR unit.
• Where there are two or more showers, drain water
  from at least two showers are required to be
  connected to a single DWHR unit or to two
  individual DWHR units.
• This Appendix Note has been added to clarify how
  many showers shall be connected to DWHR Unit(s).

SB 12 Update

• A-2.1.1.1.(7), (8) and (10) Fenestration to Wall.
• When the fenestration to wall ratio is
  calculated, all fenestration areas and the entire
  peripheral wall above grade is included.
• Peripheral wall areas include floor rim board
  areas and all above grade wall areas.
• It is essentially the sum of the above grade
  walls that separate conditioned spaces from
  unconditioned spaces, and adjacent units.
• For attached garages, the walls that are common
  with the house and the garage are also included
  in the wall area calculations.
• For attached homes, the above grade portions of
  the walls that are common to other conditioned
  units are also included in the wall area.
• This clarifies what wall areas are included in
  the total wall area.

4/25/13
15
16
SB 12 Update

• A-2.1.1.1.(7), (8) and (10) Fenestration to Wall
  Ratio (Continued).
• The fenestration area is based on the rough
  structural opening provided for windows,
  skylights, sliding glass doors, and for glazed
  portions in doors.
• For AFrame structures with steeply inclined
  roofs that also act as walls, the roof portion
  that serves as the interior wall area can be
  considered as the wall area in calculating the
  fenestration to wall ratio.
• This has been added for clarification of how
  window area is to be calculated.

4/25/13
16
17
SB 12 Update

• A-2.1.1.2.(6)(a), (8)(a), (9)(a) RSI Reduction of
  Above Grade Walls in Conjunction with Upgrading
  U-Value of Glazing - Zone 1.
• Where the above grade wall insulation is
  permitted to be reduced to RSI 3.52, one of the
  required compensating measures is to upgrade the
  window U-Value in accordance with Clauses
  2.1.1.1.(8)(a) to (c).
• This upgrade is independent of the glazing
  upgrade that may be required due to a
  fenestration ratio that is higher than 17.
• In cases where the above grade insulation is
  reduced to RSI 3.52 and compensated for with a
  fenestration upgrade, and the building has more
  than 17 fenestration, the glazing would be
  required to be upgraded a second time.
• This clarification has been added to ensure the
  overall performance of the home is maintained.
  (Similar clause added for Zone 2).

4/25/13
17
18
SB 12 Update

• A-2.1.1.6.(5) and (6) Slab Insulation.
• Except where specifically required in a
  compliance package, the entire surface of the
  slab is only required to be insulated when the
  entire concrete slab is completely within 600 mm
  (24 in) of the exterior ground level.
• A typical example would be a slab on ground
  construction without a basement.
• If a slab is partially at the exterior ground
  level (i.e. a walkout basement) or partially
  within 600 mm of the exterior surface, then only
  those parts are required to be insulated with
  perimeter insulation.
• Where a slab of a house is completely or
  partially within 600 mm of the exterior ground
  level, either the entire surface of the slab or
  the perimeter of the slab is required to be
  insulated but not at both locations.
• This has been added for clarification.

  filed as O.Reg. 332/12
• It can be found at
• www.elaws.gov.on.ca/html/source/regs/english/2012/
  elaws_src_regs_r12332_e.htm
• Requirements begin to take effect on January 1,
  2014
• This timeline allows for a transition period
  providing time for the industry to learn about
  the new changes and prepare prior to
  implementation

27
28
Next Edition of the Building Code

• The 2012 Building Code changes provide a balanced
  package that
• Builds on health and safety and environmental
  protection requirements
• Has general support from stakeholders
• Maintains Ontarios leadership in energy and
  water conservation
• Has a moderate impact on costs of construction
• Has some potential for operating cost savings
  over time (energy and water)
• Is consistent with regulatory modernization
  principles

28
29
Next Edition of the Building Code (Continued)

• The 2012 Building Code changes provide a balanced
  package that
• Helps the competitiveness of Ontarios building
  sector through
• New and updated standards
• Clarifying Building Code requirements
• Allowing for the use of new products
• Recognition of best practices
• More flexible requirements
• Maintaining Ontarios harmonization with model
  National Building Code requirements in areas such
  as structural design

29
30
Concrete Walls

• Concrete walls will now be permitted to be poured
  up to 3.0 m (9-10) of maximum height (Table
  9.15.4.2.A). This change in height is an increase
  from 2.5 m (8-2)
• Old Code (From Ministry website)
• 9.15.4.2.  Foundation Wall Thickness and Required
  Lateral Support
• (1)  Except as required in Sentence (2), the
  thickness of foundation walls made of
  unreinforced concrete block or solid concrete and
  subject to lateral earth pressure shall conform
  to Table 9.15.4.2.A. for walls not exceeding 2.5
  m in unsupported height.
• 2012 Code (From Ministry website)
• 9.15.4.2.  Foundation Wall Thickness and Required
  Lateral Support
• (1)  Except as required in Sentence (2), the
  thickness of foundation walls made of
  unreinforced concrete block or solid concrete and
  subject to lateral earth pressure shall conform
  to Table 9.15.4.2.A. for walls not exceeding 3.0
  m in unsupported height.

30
31
Property Protection and Health

• Remove window screens as an acceptable fall
  protection device as they are not deemed adequate
  as a mechanism to prevent falling of vulnerable
  occupants, especially children
• Window guards or controlled sashes would still be
  required under the Code
• Clarify that sewage back-water valves are
  required in residential buildings connected to a
  public sewage system, if deemed necessary at a
  local level
• Protecting public water supplies from
  contamination from medium hazard uses (e.g.
  multi-unit residential buildings, commercial
  buildings, hotels, manufacturing plants) by
  requiring backflow preventers

31
32
Property Protection and Health(Continued)

• Changes to the sentence (9.8.8.6.) describing
  Guards Designed Not to Facilitate Climbing
  shall be designed so that no member, attachment
  or opening located between 140 mm and 900 mm
  above the floor or walking surface protected by
  the guard will facilitate climbing. There was
  previously no dimensions.
• Revise the average annual concentration of radon
  in the Building Code to reflect the new national
  threshold (from 250 Bq/m3 to 200 Bq/m3)
• i.e., less radon is needed to trigger radon
  protection requirements
• Change affects only three areas currently
  identified in the Code

32
33
Radon / Soil Gas Control

• Proposed Rough In For Radon Venting did not move
  forward. (No national mapping program for Radon).
• Proper Radon testing
• Should be up to 3 months for more accurate
  reading.
• 48 hour test is not accurate enough.
• If excessive Radon is found,
• Simple, affordable repair detail is available.
  (Install a pipe under the basement slab
  mechanically ventilate out of the homes
  conditioned space).
• Radon is not the only soil gas that is a concern.
  
• Continuous Air Barrier is now a requirement
  including basements to manage soil gases.

Sewage Back Water Valves

• Municipal liability is the driver here.
• Many municipalities now requiring backwater
  valves to limit their liability in case of a
  storm event, even if there is limited evidence
  that this is an issue. 
• Municipality decision to determine the need for
  backwater valves in any area or the entire
  municipality.  
• Most municipalities that are requiring backwater
  valves are requiring them throughout.
• For example St. Thomas is updating their bi-laws
  to require backwater valves for new construction.
  The most recent incident occurred as a result of
  municipal sub-contractor cleaning the sewer line.

Fire Safety

• The 2012 Building Code contains specific
  requirements in order to enhance fire protection
  of large and small buildings, including
• Requiring hard-wired smoke alarms with battery
  back-up in each sleeping room for houses and
  large buildings (Part 3 and Part 9)
• Requiring integrated sprinkler and fire alarm
  systems in multi-unit residential buildings

41
42
Fire Safety

• Smoke detectors vs. sprinkler systems
• Smoke detectors and sprinkler systems save
  relatively same number of occupants.
• Smoke detectors are far more cost effective.
• Best recommended practice is for a dedicated
  CO/smoke detector in every bedroom.
• This was a recommendation by OHBA for the new
  code.

Fire Safety

• Smoke Detectors
• Ionization detectors are the most common type,
  but do not quickly detect smouldering fires
• Photo electric detectors appear to be much more
  responsive to detecting smouldering fires.
• Best is having both types or a dual detector.
• Children are susceptible to sleeping through a
  fire alarm (they sleep differently than adults)
  // Children appear to respond better to alarm
  with recorded parent voice but these are not
  mainstream.
• Excellent episode on Dateline. (Rossen Some
  smoke detectors may not go off in time)

4/25/13
44
45
Fire Safety

• The 2012 Building Code does not include
• Reference to the National Fire Protection
  Association Standard 1710 (Limiting Distance),
  related to calculation of fire department
  response times
• New provisions for fire protection of soffits to
  protect buildings built close to the property line

Fire Safety Changes in NBC!
Proposed Changes affecting Building Design and
Cost

• OHBA actively met with the Ministry including
  with Minister Wynne about our concerns with Part
  9.10.
• Two main areas of Concern
• Overhangs to be protected within the 4 ft side
  yard.
• 10 minute fire emergency response time.
• Proposed changes could have added from 10K to
  100K in additional lot costs due to the need for
  wider side yards.
• Alternative would be more fire stations.
  Municipalities were also against this proposal as
  the cost of staffing new fire stations would fall
  upon taxpayers.
• Minister Wynne Ontario will not harmonize with
  the National Code unless it makes sense for
  Ontario. Neither proposal was included in the
  OBC.

4/25/13
46
47
Fire Safety Changes in NBC!

• Fire Code Alert From CHBA, May 19, 2011
• The CHBA alert recommended that provincial HBAs
  contact their respective provincial governments
  to try to defer implementation of the new fire
  code requirements pending a national review.
• The National Code Working Group is now meeting to
  correct what was added with 9.10 to the 2010
  National Building Code as the implementation in
  Alberta is causing chaos.
• NOTE OHBA has been active on this file since
  Fall of 2010.

4/25/13
47
48
Code Objectives

• The 2012 Building Code expands the list of
  Building Code sub-objectives and related
  functional statements to reference
• Limiting the extent to which construction strains
  infrastructure capacity (e.g. electrical grid
  capacity)
• Protecting atmospheric quality
• Limiting green house gas emissions
• Limiting the release of pollutants
• Protecting water and soil quality

48
49
Energy Conservation Requirements

• Houses
• The 2012 Building Code promotes energy
  conservation through building design and
  construction by
• Requiring that houses for which building permits
  are applied on or after January 1, 2017 meet an
  energy efficiency level that is 15 higher than
  that required in 2012
• Providing compliance alternatives on how to
  achieve that goal and
• Over the 5 year Code cycle, require a number of
  other energy conserving incremental changes (e.g.
  January 1, 2015 - ECM motors, programmable
  thermostats)
• As with the approach taken with large buildings,
  MMAH intends to work with the building sector to
  achieve these future requirements

49
50
Improvements to HVAC Systems

• OHBA advocated for furnaces to have DC (ECM)
  Motors.
• Tighter homes combined with furnace oversizing
  will result in short cycling (warm main floor and
  cold extremities).
• This will become an increasing area of warranty
  complaints.
• A DC motor will allow the furnace fan to run on a
  more continuous basis, reducing the effect of
  short cycling.

4/25/13
50
51
Energy Efficiency for Small Buildings

• Small Buildings
• The 2012 Building Code does not include
  requirements for solar conduits
• This issue can be revisited when structural
  requirements are clarified
• Tables outlining these requirements are under
  development at the national code centre

51
52
52
53
Water Conservation

• The 2012 Building Code promotes the conservation
  of Ontarios water through building design by
• Requiring newly installed urinals to be high
  efficiency (1.9 litres/flush),
• Requiring newly installed toilets in residential
  buildings with a connection to a public sewer to
  be high efficiency (4.8 litres/flush or 3/6
  litres dual-flush), and
• Requiring high efficiency showerheads (7.6
  litres/minute) in residential occupancies

53
54
Water Conservation

• Opportunities for innovation are provided by
• Allowing for drainless composting toilets in
  areas with municipal services
• Expanding the end uses of rainwater and other
  non-potable water,
• Clarifying the design requirements of non-potable
  water systems,

54
55
Water Conservation

• Municipal Governments are dealing with increased
  costs for water treatment, both for potable water
  supply and sewage treatment.

57
Water Conservation

• Water treatment in many municipalities has become
  their largest electricity expense.
• The need to reduce usage is becoming a critical
  budgetary issue even for communities with
  abundant access to water.
• The additional demand for water treatment will
  also add to the long term need for more
  electrical generation capacity.

Water Conservation

• The last election proved that NIMBYISM is alive
  and well. Nobody wants one of these in their
  back yard.

4/25/13
58
59
Water Conservation

• Changes reflect the need to manage these costs.
  Two examples
• Low Flow Showerheads (From 9.5 to 7.6L/min.)
• Toilets (From 6 to 4.8L/ flush).

On-Site Sewage Systems

• The 2012 Building Code
• Adopts the new CAN-BNQ 3680-600 national standard
  for wastewater residential treatment
  technologies, as proposed in public consultation
• Testing would be conducted at uncontrolled
  temperatures or at temperatures not exceeding 11
  Celsius, to reflect Ontario climatic conditions
• Adopts a number of changes, including several
  suggested by Ontario Code users, updating
  technical, maintenance, and monitoring
  requirements

60
61
On-Site Sewage Systems (cont.)

• Establishes standards for dispersal beds in the
  Building Code, including
• Two types of dispersal beds
• Prescriptive as well as performance requirements
• This would require additional training on
  designing and installing systems to a
  performance-based standard for the on-site sewage
  industry
• The 2012 Building Code also
• Signals future intent to address nutrient
  reduction in at-risk areas
• No Building Code changes were introduced at this
  time
• MMAH will continue to work with Ministry of the
  Environment on potential approaches to nutrient
  reduction

61
62
Harmonization and Consistency

• The 2012 Building Code enhances harmonization
  with the model National Building and Plumbing
  Codes, including
• Editorial changes and updated standard
  references, stemming from changes to the model
  national codes
• Clarifying technical requirements to ensure
  consistency and clarity in enforcement
• Allowing more flexible, performance-oriented
  methods, design and installation of some building
  elements
• Amends the Building Code to enhance consistency
  with the
• Electrical Safety Code (no changes to Electrical
  Safety Code required)

62
63
Harmonization and Consistency (cont.)

• The 2012 Building Code does not include
• Changes related to care occupancies that were
  included in recent model National Building Code
• Ontarios Code has contained similar
  requirements since the 1990s but the drafting
  differs from the national approach

63
64
Administrative Changes

• The 2012 Building Code
• Requires copies of Ministers Rulings authorizing
  the use of innovative building materials to be
  kept at the construction site where a Ruling
  applies
• Currently applies to BMEC authorizations
• Requires thermal protection for foam plastic
  insulation as a condition for residential
  occupancy
• Currently, the Code allows for occupancy while
  foam plastic insulation is exposed (e.g., in a
  basement). This presents a health and fire safety
  concern.
• Code change requires the foam plastic insulation
  to be covered (e.g., by drywall) in advance of
  occupancy
• Removes requirement for final site grading as a
  condition of occupancy permit issuance

64
65
Administrative Changes (cont.)

• The 2012 Building Code does not
• Require a permit for the demolition of farm
  houses

66
Knowledge Maintenance

• The 2012 Building Code simplifies the
  re-qualification requirements for practitioners
  currently qualified under the Building Code
• Successful completion of a knowledge maintenance
  re-assessment replaces the need to fully
  re-qualify by taking new entrant examinations.
  Key aspects
• Director of the Building and Development Branch
  to determine qualification categories where
  knowledge maintenance is to be required
• Fee will apply to complete the on-line
  re-qualification exam
• Re-qualification exam questions will be
  randomized
• A non-mandatory online course will be offered for
  each area of re-qualification
• Applicants have 18 months to complete
  qualification courses following notification by
  the Director
• Ministry is exploring options for design,
  maintenance and delivery of the online course
• New entrants would still have to pass standard
  Ministry qualification exams

Mid-Rise Wood Construction

• The 2012 Building Code does not include changes
  to permit wood framed buildings 4 storeys or more
• MMAH is participating in research being
  undertaken by the National Research Council (NRC)
  through staff resources and financial
  contribution
• The NRC has proposed research on mid-rise and
  other wood based construction to support proposed
  changes to the 2015 edition of the model National
  Building Code
• Decisions on potential future Building Code
  changes will be made on the basis of this
  information

Glass Panels in Balcony Guards

• In the summer of 2011, concerns were raised about
  spontaneous failures of glass balcony guards,
  generally in multi-residential buildings
• MMAH established an Expert Advisory Panel on
  Glass Panels in Balcony Guards to provide
  recommendations on whether and how to amend the
  Building Code to address the issue of breakage of
  glass panels in balcony guards
• The Panel put forward seven recommendations to
  the Ministry and the government has since adopted
  all recommendations

73
74
Glass Panels in Balcony Guards (cont.)

• Ontario Regulation 159/12 was filed on June 20,
  2012 and came into force on July 1, 2012
• The amendment incorporates, by reference, new
  MMAH Supplementary Standard SB-13, Glass in
  Guards
• The amendments include
• Requiring the use of heat-strengthened laminated
  glass when glass is close to or beyond the edge
  of a balcony
• Permit the use of heat-soaked tempered glass
  where glass balcony guards are inset a certain
  distance from the edge of the balcony
• These requirements apply to new construction only

75
Accessibility

• The Accessibility for Ontarians with Disabilities
  Act, 2005 (AODA) called for the creation of
  accessibility standards to make Ontario
  accessible for persons with disabilities by 2025
• Ontarios Building Code has included requirements
  for barrier-free design since 1975
• In July 2010, a Final Proposed Accessible Built
  Environment Standard was submitted for
  governments consideration
• These recommendations were not included in
  2010-2011 consultations on the Next Edition of
  the Building Code

75
76
Accessibility (cont.)

• MMAH is currently developing proposed policy
  direction for including new accessibility
  standards in the Building Code
• Public consultation on potential Building Code
  changes, as well as Technical Advisory Committee
  reviews, will be conducted prior to amending the
  Building Code
• Public consultation has commenced
• MMAH has engaged LMCBO, OBOA, AMO and Toronto to
  provide input/advice on the proposed Code changes
  for consultation. OHBA is also participating.

76
77
Accessibility is on the Horizon

• OHBA was contacted by the Branch Director Brenda
  Lewis regarding participation on the Barrier-Free
  Design Technical Advisory Committee to be held
  this spring.
• For the moment Accessibility requirement changes
  to OBC are on hold.
• Changes to be consulted on will likely focus
  primarily on Buildings rather than Houses (Part
  9).
• They may be implemented during the 2012 Code
  cycle or at the beginning of the Next Code Cycle.
• May or may not happen universally.

Accessibility / Universal Design vs. Visitability

• Universal Design
• has wider doors and halls,
• adequate turning space,
• controls at appropriate height
• Anticipates that certain features may be added
  easily later.
• Visitability
• Someone with accessibility needs can visit the
  home at any time.
• Features include a fully accessible entry,
• a visiting room,
• wider main hallway and doors
• and toilet facility all on the main entry floor
  of the home.

Key Accessibility Ideas

• Visitability Requirement Challenges Include
• Universal grade-level access in all areas of the
  province.
• Certain Home Designs dont work (Split Level /
  Raised Ranch / 3 Storey Walk-Up).
• Example back to front grade with ramp, ramp
  finally hits the ground... On the other side of
  the street.

Accessibility and Usability

• Not Sure about Accessible Design? Dont Fake It!

Here is a beautiful accessible curved ramp under
Construction.
So whats wrong with this design?

Accessibility and Usability
For Starters this 3 bag of concrete slope at the
porch Door does not meet code.
Its about a 13 slope, rather than a 110 slope
or higher.

Accessibility and Usability
Which should enable the occupant of
the wheelchair to hit WARP 9 on one wheel coming
down the ramp.
There is no railing or curb on the ramp to keep
from sliding off.
This homeowner could not enter their home. They
ultimately built a ramp in the garage. They lost
the use of the garage.
While initially cheaper, this builder ultimately
cost the homeowner the proper use of their home.
