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
  • 1.1.1. Energy Efficiency Compliance
  • 1.1.1.1. Energy Efficiency
  • Same.
  • (2) The energy efficiency of existing buildings
    shall comply with
  • Part 10 of Division B of the Building Code with
    respect to change of use, or
  • Part 11 of Division B of the Building Code for
    renovation. (This is a clarification for
    renovators. Except as noted later, SB12 has
    little impact on Renovations).

SB 12 Update
1.1.1.2. Compliance Options (1) Same. (2)
Factory built modular homes manufactured before
January 1, 2012 in accordance with the Building
Code as it read on December 31, 2011 shall be
deemed to be in compliance with Sentence (1).
(This is a clarification for previously
constructed modular homes).

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.

SB 12 Update
  • Notes to Table 2.1.1.2.A
  • Same.
  • Same.
  • Same.
  • Only the hot water heating equipment shall meet
    the minimum AFUE or EF specified in the Table or
    shall be of the condensing type. (Was Combined
    space heating and domestic hot water heating
    equipment shall have minimum energy efficiency
    ratings specified or shall be of the condensing
    type.)
  • Clarifies thermal requirements of water heater
    when used as the household heating source.
  • Applies to Package M.

SB 12 Update
2.1.1.2. Energy Efficiency for Zone 1 Buildings
(Continued)
  • (5) Where the thermal performance of above grade
    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.

4/25/13

SB 12 Update
  • Drain Water Heat Recovery (DWHR) has been added
    as a compliance option.
  • (10) Where a DWHR unit conforming to Article
    2.1.1.11. is provided in addition to the
    requirements of a compliance package selected
    from Tables 2.1.1.2.A to 2.1.1.2.C.
  • the thermal insulation value in exposed above
    grade walls is permitted to be not less than RSI
    3.52 (R20) where it is required to be RSI 3.87
    (R22),
  • the thermal insulation value in exposed above
    grade walls is permitted to be not less than RSI
    3.52 (R20) where it is required to be RSI 4.23
    (R24), provided that the drain water heat
    recovery unit has a minimum efficiency of not
    less than 46,

4/25/13

10
SB 12 Update
  • (10) Continued
  • the thermal insulation value in basement walls is
    permitted to be not less than RSI 2.11 where it
    is required to be RSI 3.52,
  • the overall coefficient of heat transfer of
    glazing is permitted to be not greater than 1.8
    W/m2AK where it is required to be 1.6 W/m2AK, or
    not greater than 1.6 W/m2AK where it is required
    to be 1.4 W/m2AK,
  • the minimum efficiency of an HRV is permitted to
    be not less than 55 where it is required to be
    75 or less, or
  • the minimum efficiency of a furnace is permitted
    to be not less than 90 where it is required to
    be 94.

4/25/13
10
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
11
12
SB 12 Update
  • Requirements for the use of DWHR Unit as a
    compliance alternative.
  • 2.1.1.11. Drain Water Heat Recovery
  • Where a DWHR unit is installed to meet the
    requirements of this Subsection, the unit and its
    installation shall conform to Sentences (2) to
    (5).
  • DWHR units shall conform to CSA B55.2,Drain
    Water Heat Recovery Units.
  • The minimum efficiency of a DWHR unit shall be
    determined in conformance with CSA B55.1, Test
    Method for Measuring Efficiency and Pressure Loss
    of Drain Water Heat Recovery Units.

4/25/13

SB 12 Update
  • 2.1.1.11. Drain Water Heat Recovery (Continued)
  • A DWHR unit shall be installed
  • to receive drain water from all showers or at
    least two showers where there are two or more
    showers in a dwelling unit, (See Appendix A.)
  • in an upright position that does not diverge more
    than 5 degrees from the vertical,
  • in a position such that the cold water inlet
    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
    unit shall be not less than 36 when it is tested
    in accordance with Sentence (3).

4/25/13
13
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).

4/25/13

15
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

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.

Next Edition of the Building Code(Status)
  • On November 2, 2012, the 2012 Building Code was
    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.

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.

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

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.

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

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.

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
  • 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
  • Require municipal inspectors to complete a
    written inspection report at each stage of
    inspection

65
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

66
67
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

  • Potential development of an electronic version of
    the next edition
  • MMAH has released a survey to seek input of
    business needs for an eversion, and will be
    arranging meetings with stakeholders

71
72
Updated Guidelines and Best Practices
  • MMAH is reviewing current guidelines and best
    practices to determine which ones should be
    updated to reflect the content of the next
    edition of the Code
  • Interest has been expressed by stakeholders in
    developing electronic versions of certain
    products (Example Code and Construction Guide of
    Housing)

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

74
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.

79
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
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.
