Notes to Table 9.23.4.2.-H:
(1) Beam spans apply only where the floors serve residential areas as described in Table 4.1.5.3., or the uniformly distributed live load on the floors does not exceed that
specified for residential areas as described in Table 4.1.5.3.
(2) When the floors have a concrete topping of not more than 51 mm, the spans must be multiplied by 0.8.
(3) Supported length means half the sum of the joist spans on both sides of the beam.
(4) Straight interpolation may be used for other supported lengths.
(5) Spans are clear spans between supports. For total span, add two bearing lengths.
(6) 3-ply beams with supported lengths greater than 4.2 m require 114 mm bearing. All other beams require 76 mm bearing.

Notes to Table 9.23.4.2.-I:
(1) Beam spans apply only where the floors serve residential areas as described in Table 4.1.5.3., or the uniformly distributed live load on the floors does not exceed that
specified for residential areas as described in Table 4.1.5.3.
(2) When the floors have a concrete topping of not more than 51 mm, the spans must be multiplied by 0.8.
(3) Supported length means half the sum of the joist spans on both sides of the beam.
(4) Straight interpolation may be used for other supported lengths.
(5) Spans are clear spans between supports. For total span, add two bearing lengths.
(6) 3-ply beams require 114 mm bearing. 4-ply and 5-ply beams with supported lengths greater than 3 m require 114 mm bearing. All other beams require 76 mm bearing.

Notes to Table 9.23.4.2.-K:
(1) Spans apply only where the floors serve residential areas as described in Table 4.1.5.3., or the uniformly distributed live load on the floors does not exceed that specified
for residential areas as described in Table 4.1.5.3.
(2) Supported length means half the sum of the joist spans on both sides of the beam.
(3) Straight interpolation may be used for other supported lengths.
(4) Spans are valid for glued-laminated timber conforming to CAN/CSA-O122 and CSA O177.
(5) Spans are clear spans between supports. For total span, add two bearing lengths.

10% for supported lengths of not more than 3.7 m, and by 25% for supported lengths of not more than 2.4 m.
(2) For ridge beams, supported length means half the sum of the rafter, joist or truss spans on both sides of the beam. For lintels, supported length means half the sum of
truss, roof joist or rafter spans supported by the lintel plus the length of the overhang beyond the lintel.
(3) Provide minimum 76 mm bearing.

Notes to Table 9.23.12.3.-A:
(1) Where structural sheathing is used, lintel spans may be increased by 15%. Structural sheathing consists of a minimum 9.5 mm thick structural panel conforming to
CSA O121, CSA O151, CSA O325 or CSA O437.0 fastened with at least two rows of fasteners to the exterior face of the lintel, and a single row to the top plates and
studs. Fasteners shall conform to Table 9.23.3.5.-A.
(2) A single piece of 89 mm thick lumber may be used in lieu of 2 pieces of 38 mm thick lumber on edge.
(3) If floor joists span the full width of the building without support, lintel spans shall be reduced by 15% for “roof, ceiling and 1 storey,” by 20% for “roof, ceiling and 2 storeys,”
and by 25% for “roof, ceiling and 3 storeys.”
(4) For ends of lintels fully supported by walls, provide minimum 38 mm bearing for lintel spans up to 3 m, or minimum 76 mm bearing for lintel spans greater than 3 m.
(5) Spans for 0.6 m tributary width are calculated for lintels in end walls that support only a 0.6 m width of roof and ceiling, but do not support roof joists, roof rafters or roof
trusses.
(6) Lintel spans are calculated based on a maximum floor joist, roof joist or rafter span of 4.9 m and a maximum roof truss span of 9.8 m. Lintel spans may be increased by
5% if rafter and joist spans are no greater than 4.3 m and roof truss spans are no greater than 8.6 m. Spans may be increased by 10% if rafter and joist spans are
no greater than 3.7 m and roof truss spans are no greater than 7.4 m.
(7) Spans apply only where the floors serve residential areas as described in Table 4.1.5.3., or the uniformly distributed live load does not exceed that specified for residential
areas as described in Table 4.1.5.3.

to 10.2.3.3.-H
or to Step 3 in Tables 10.2.3.3.-I and 10.2.3.3.-J, and to the Passive House Planning Package, version 9
or newer, are deemed to comply with this Subsection provided the energy model according to which the building or
the major occupancy of the building is designed and constructed is prepared by a Certified Passive House Designer, or
Certified Passive House Consultant, who is approved by the Passive House Institute.
(See also Sentence 10.2.2.1.(2).)
10.2.3.4. Energy Modelling
(See Note A-10.2.3.4.)
1) Except as required by Sentence (2), for buildings and major occupancies conforming to the requirements of any of
Steps 1 to 4, energy modelling shall conform to
a) the applicable requirements of Part 8 of the NECB, and
b) the City of Vancouver Energy Modelling Guidelines.
2) Except as permitted by Sentence (3), energy modelling for buildings and major occupancies conforming to the
requirements of any of Steps 2 to 4 shall account for the air leakage rate derived in accordance with Article 10.2.3.5.
3) Until the air leakage rate determined by Sentence (2) is available, an air leakage rate determined in accordance
with the City of Vancouver Energy Modelling Guidelines shall be used.
4) In case of conflict between the provisions of the NECB and the City of Vancouver Energy Modelling
Guidelines, the provisions of the City of Vancouver Energy Modelling Guidelines shall govern.
10.2.3.5. Building Envelope Airtightness Testing
1) Except as required by Sentence (2), buildings and major occupancies shall be tested for airtightness in accordance
with
a) ASTM E 779, “Standard Test Method for Determining Air Leakage Rate by Fan Pressurization”, or
b) USACE Version 3, “Air Leakage Test Protocol for Building Envelopes”.
(See Note A-10.2.3.5.(1).)
2) Where airtightness is determined in accordance with Sentence (1) with intentional openings for mechanical
equipment left unsealed, the airtightness rate shall be adjusted in the energy model calculations to account for air
leakage through mechanical equipment.
3) Buildings and major occupancies shall be tested for airtightness to an induced test pressure of not less than 75 Pa.
