Area =  area of the unprotected opening in m2, and

LD =  limiting distance in m.

(c)  consists of two or more stacked spaces that are on the same storey.

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

(9) 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:

AC = A + (AF × FEO)

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:

FEO =

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.

(10) 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 (9) shall be added to the greater of,

(a)  the actual area of unprotected openings, or

(b)  the corrected area of unprotected openings.

(11) 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.

(12) Where an agreement referred to in Sentence (11) 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.
