58 Appendix Note A-3.1.2.1.(1) is amended under the heading “Group A, Division 2” by adding “Daycare facilities for children” below “Dance halls”.

59 The following Appendix Note is added:

A-3.1.2.8. Daycare Facilities for Children. A daycare facility for children is typically occupied for a period of less than 24 hours each day (i.e., is not a residential facility). The term “daycare” is not meant to exclude facilities that provide short term care during the night for a period of less than 24 hours each day. (See also A-3.3.2.16.)

60 The following Appendix Note is added:

A-3.3.2.16. Daycare Facilities with Children under 30 Months. These daycare facilities are subject to additional requirements to address the unique profile of the occupants. (See also A-3.1.2.8.)

61 Appendix Note A-4.1.5.8. is amended by striking out “entitled Tributary Area” and substituting “entitled Live Loads”.

62 Appendix Note A-6.2.2.6.(1) is amended by striking out “NFPA 55, “Storage, Use, and Handling of Compressed Gases and Cryogenic Fluids in Portable and Stationary Containers, Cylinders, and Tanks” ” and substituting “NFPA 55, “Compressed Gases and Cryogenic Fluids Code” ”.

63 Appendix Note A-9.1.1.1.(1) is amended

(a) by adding the following paragraph above the paragraph titled “Thermal Insulation”:

Energy Efficiency

Clause 9.36.1.3.(5)(b) exempts seasonally occupied residential buildings such as summer cottages from the requirements of Section 9.36. Cottages intended for continuous or regular winter use such as ski cabins are required to conform to Section 9.36. ,

(b) by repealing the paragraph titled “Thermal Insulation” and substituting the following:

Thermal Insulation

Article 9.25.2.1. specifies that insulation is to be installed in walls, ceilings and floors that separate heated space from unheated space. Cottages intended for use only in the summer and which, therefore, have no space heating appliances, would not be required to be insulated. Should a heating system be installed at some later date, insulation should also be installed at that time in accordance with Article 9.25.1.1. and the insulation tables in Section 9.36. However, if the building were not intended for continuous or regular winter use, it may still be exempted from the remainder of the energy efficiency requirements in Section 9.36. , and

(c) by repealing the paragraph titled “Air Barrier Systems and Vapour Barriers” and substituting the following:

Air Barrier Systems and Vapour Barriers

Articles 9.25.3.1. and 9.25.4.1. require the installation of air barrier systems and vapour barriers only where insulation is installed. Dwellings with no heating system would thus be exempt from these requirements. In some cases, seasonally occupied buildings that are conditioned may be required to conform to the air and vapour barrier requirements of Section 9.25, but not to the air barrier and other requirements of Section 9.36.

64 Appendix Note A-9.3.2.1.(1) is amended in Table A-9.3.2.1.(1)A. and in the third paragraph by striking out “NLGA 2007,” and substituting “NLGA 2010,”.

(b) by striking out “CSA O112.6-M, “Phenol and Phenol-Resorcinol Resin Adhesives for Wood (High-Temperature Curing).” ” and substituting “CSA O112.9, “Evaluation of Adhesives for Structural Wood Products (Exterior Exposure).” ”.

68 Appendix Note A-9.13.4. is amended by adding “system” after “between the air barrier”.

69 Appendix Note A-9.13.4.3. is amended

(a) by adding “System” after “Between the Air Barrier”, and

(b) by repealing the paragraph titled “Completion of a Subfloor Depressurization System” and substituting the following:

Completion of a Subfloor Depressurization System

The completion of a subfloor depressurization system may be necessary to reduce the radon concentration to a level below the guideline specified by Health Canada. In this case, to complete the system, the radon vent pipe is mechanically assisted to enable effective depressurization of the space between the air barrier system and the ground. An electrically powered fan is typically installed somewhere along the radon vent pipe.

Further information on protection from radon ingress can be found in the following Health Canada publications:

• “Radon: A Guide for Canadian Homeowners” (CMHC/HC), and

• “Guide for Radon Measurements in Residential Dwellings (Homes).”

70 Appendix Note A-9.13.4.3.(2)(b) and (3)(b)(i) is amended

(a) by adding “system” after “between the air barrier” in both places,

(b) by deleting Figure A-9.13.4.3.(2)(b) and (3)(b)(i), and

(c) by renumbering the Appendix Note as Appendix Note A-9.13.4.3.(2)(b)(i) and (3)(b)(i).

71 The following Appendix Note is added:

A-9.13.4.3.(3)(b) Vent Terminals. To prevent soil gases from entering a building through air intakes, windows, and other openings in the building envelope, radon vent pipe terminations should be installed in a similar manner to plumbing vent terminals. (See A-2.5.6.5.(4) in Appendix A of Division B to Book II of the Code.)

72 The following Appendix Note is added:

A-9.16.2.1.(1) Drainage Layer Beneath Floors-on-Ground. A drainage layer required by Sentence 9.16.2.1.(1) shall also be gas-permeable and conform to Article 9.13.4.3. in buildings to which that Article applies.

73 Appendix Note A-Table 9.23.4.3. is amended

(a) by striking out “live load = 1.9 kPa” and substituting “live load: first floor = 1.9 kPa; second floor = 1.4 kPa”, and

(b) by striking out “dead load = 1.5 kPa” and substituting “dead load = 1.5 kPa (0.5 kPa floor + 1.0 kPa partition)”.

74 Appendix Note A-9.23.10.4.(1) is amended by striking out “NLGA 2007,” and substituting “NLGA 2010,”.

75 Appendix Note A-9.27.3.1. is amended by striking out “10 mm” wherever it appears and substituting “9.5 mm”.

76 Appendix Note A-9.32.3. is repealed and the following substituted:

A-9.32.3. Heating-Season (Mechanical) Ventilation. While ventilation strategies can have a significant impact on energy performance, ventilation is primarily a health and safety issue. Inadequate ventilation can lead to mold, high concentrations of CO₂, and other indoor air pollutants, which can lead to adverse health outcomes. Previous editions of the British Columbia Building Code relied on ventilation through the building envelope in combination with a principal exhaust fan. However, with the increased attention on the continuity of the air barrier system in buildings, builders can no longer rely on uncontrolled ventilation through the building envelope. In most buildings, mechanical systems will be required to provide adequate ventilation for occupants.

As described in Article 9.32.3.3., every dwelling unit must include a principal ventilation system. A principal ventilation system is the combination of an exhaust fan and a supply fan (or passive supply in some instances: see Sentence 9.32.3.4.(6)).

The principal ventilation system exhaust fan is separate from the requirements for a fan in every bathroom and kitchen. While a bathroom fan may be used to satisfy both the requirements for the principal ventilation exhaust fan and the requirements for a bathroom fan, the requirements for each must be met. If the fan provides this combined function of the principal ventilation exhaust fan and the bathroom fan, it will also need to have controls that conform to Sentences 9.32.3.5.(3) and (4). Unlike other bathroom fans, the principal ventilation exhaust fan is required to run continuously and should not have a control switch in a location where it may be turned off inadvertently.

77 The following Appendix Note is added:

A-9.32.3.4. Principal Ventilation System Supply Air.

Figure A-9.32.3.4.(2) Forced-Air Heating System Supply Air Distribution

78 The following Appendix Note is added:

A-9.32.3.4.(6)(a)(ii) Floor Area Calculation for Passive Supply Air Distribution. The floor area to be calculated for Subclause 9.32.3.4.(6)(a)(ii) does not include sun porches, enclosed verandas, vestibules, attached garages, or other spaces that are outside the building envelope and do not require ventilation supply air.

79 Appendix Note A-9.32.3.8.(1)(a) is repealed and the following substituted:

A-9.32.4.1.(1)(a) Naturally Aspirating Fuel-Fired Vented Appliance (NAFFVA). NAFFVA, typically appliances with draft hoods, are subject to back drafting when a negative pressure condition occurs in the dwelling. The following tables describe the conditions under which Clause 9.32.4.1.(1)(a) applies:

80 Appendix Note A-9.36.1.3.(5) is repealed and the following substituted:

A-9.36.1.3.(5) Exemptions. Examples of buildings and spaces that are exempted from the requirements of Section 9.36. include

• seasonally occupied buildings,

• storage and parking garages,

• service buildings and service rooms,

• unconditioned buildings such as storage warehouses, and

• unconditioned spaces in buildings.

However, note that, where a building envelope assembly of an exempted building is adjacent to a conditioned space, this assembly must meet the requirements of Section 9.36.
