(4) For the purpose of determining the actual percentage of unprotected openings permitted in an exterior wall, the location of the exposing building face is permitted to be taken at a vertical plane located so that there are no unprotected openings between the vertical plane and the line to which the limiting distance is measured.

(5) If a building has any storey that is not sprinklered and fire fighting facilities cannot reach it within 10 min of the alarm being received, the required limiting distance shall be doubled.

(6) If the surface temperature on the unexposed surface of a wall assembly exceeds the temperature limit of a standard fire test as permitted by Article 3.1.7.2., an allowance shall be made for the radiation from the hot unexposed wall surface by adding an equivalent area of unprotected opening to the area of actual openings as follows:

where

Ac	=	corrected area of unprotected openings including actual and equivalent openings,
A	=	actual area of unprotected openings,
AF	=	area of exterior surface of the exposing building face exclusive of openings on which the temperature limit of the standard test is exceeded, and
FEO	=	an equivalent opening factor derived from the following expression:

where

Tu	=	average temperature in degrees Celsius of the unexposed wall surface at the time the required fire-resistance rating is reached under test conditions,
Te	=	892°C for a fire-resistance rating not less than 45 min, 927°C for a fire-resistance rating not less than 1 h, and 1 010°C for a fire-resistance rating not less than 2 h.

(7) Unless a closure used to protect an opening in an exposing building face has a protective performance equivalent to that required for the wall assembly in which it is located, an equivalent area of unprotected opening, determined in accordance with the procedures of Sentence (6) shall be added to the greater of

(a) the actual area of unprotected openings, or

(b) the corrected area of unprotected openings.

(8) The required limiting distance for an exposing building face is permitted to be measured to a point beyond the property line that is not the centre line of a street, lane or public thoroughfare if

(a) the owners of the properties on which the limiting distance is measured and the municipality enter into an agreement in which such owners agree that

(i) each owner covenants that, for the benefit of land owned by the other covenantors, the owner will not construct a building on his or her property unless the limiting distance for exposing building faces in respect of the proposed construction is measured in accordance with the agreement,

(ii) the covenants contained in the agreement are intended to run with the lands, and the agreement shall be binding on the parties and their respective heirs, executors, administrators, successors and assigns,

(iii) the agreement shall not be amended or deleted from title without the consent of the municipality, and

(iv) they will comply with such other conditions as the municipality considers necessary, including indemnification of the municipality by the other parties, and

(b) the agreement referred to in Clause (a) is registered against the title of the properties to which it applies.

(9) Where an agreement referred to in Sentence (8) is registered against the title of a property, the limiting distance for exposing building faces shall be measured to the point referred to in the agreement.

3.2.3.2. Area of Exposing Building Face

(3) The fire-resistance rating of the fire separations referred to in Sentence (2) is permitted to be less than 1 h but not less than 45 min provided the fire-resistance rating required by Subsection 3.2.2. is permitted to be less than 1 h for

(a) the floor assembly above the fire compartment, or

(b) the floor assembly below the fire compartment, if there is no floor assembly above.

(4) Except as required by Sentence (5), if a building containing Group E or Group F, Division 1 or 2 occupancies is divided by fire separations into fire compartments, the area of exposing building face is permitted to be calculated for each fire compartment provided the fire separations have a fire-resistance rating not less than 45 min.

(5) The fire-resistance rating of the fire separations referred to in Sentence (4) shall be not less than that required by Subsection 3.2.2. for

(a) the floor assembly above the fire compartment, or

(b) the floor assembly below the fire compartment, if there is no floor assembly above.

(6) For the purposes of Sentence (1), where a horizontal fire separation is penetrated by openings that are not provided with closures, and the openings are in conformance with Article 3.2.8.2., the fire separation is permitted to be considered as enclosing construction for the purposes of determining fire compartments.

(7) For the purposes of Sentence (1), where an interconnected floor space is in conformance with Articles 3.2.8.3. to 3.2.8.11., each storey in the interconnected floor space is permitted to be considered a fire compartment.

3.2.3.3. Wall Enclosing Attic or Roof Space

(1) An exterior wall enclosing an attic or roof space and located above an exposing building face, shall be constructed in conformance with the requirements for the exposing building face.

3.2.3.4. Party Wall

(1) A party wall shall be constructed as a firewall.

3.2.3.5. Wall with Limiting Distance less than 1.2 m

(1) Openings in a wall that has a limiting distance less than 1.2 m shall be protected by closures whose fire-protection rating is in conformance with the fire-resistance rating required for the wall.

(2) Wired glass or glass block shall not be used for a closure referred to in Sentence (1).

3.2.3.6. Combustible Projections

(1) Except for a building containing one or 2 dwelling units only, combustible projections on the exterior of a wall that could expose an adjacent building to fire spread and are more than 1 000 mm above ground level, including balconies, platforms, canopies, eave projections and stairs, shall not be permitted within

(a) 1 200 mm of a property line or the centreline of a public way, or

(b) 2 400 mm of a combustible projection on another building on the same property.

3.2.3.7. Construction of Exposing Building Face

(1) Except as permitted by Articles 3.2.3.9. and 3.2.3.10., if a limiting distance shown in Table 3.2.3.1.A. or Table 3.2.3.1.C. for a Group A, B, C, D or Group F, Division 3 occupancy classification permits an exposing building face to have unprotected openings not more than 10% of the exposing building face, the exposing building face shall be

(a) of noncombustible construction having a fire-resistance rating not less than 1 h, and

(b) clad with noncombustible cladding.

(2) Except as permitted by Sentence (9) and Articles 3.2.3.9. and 3.2.3.10., if a limiting distance shown in Table 3.2.3.1.A. or Table 3.2.3.1.C. for a Group A, B, C, D or Group F, Division 3 occupancy classification permits an exposing building face to have unprotected openings more than 10% but not more than 25% of the exposing building face, the exposing building face shall
