A-3.2.3.1.(4) Spatial Separation Design

 A-3.2.3.1.(4) Spatial Separation Design

In the application of Sentences 3.2.3.1.(3) and (4), it is intended that Sentence (3) be used first to establish the basic requirements for the exterior wall in terms of fire-resistance rating, type of construction and type of #cladding. The percentage of unprotected openings determined from the application of Sentence (3) would be unnecessarily restrictive if the actual unprotected openings occur in a plane that is set back from the front of the building face.

Sentence (4) applies to the calculation of the allowable percentage of unprotected openings based upon #projection onto a plane that is in front of all unprotected openings. The application of these two Sentences is shown in Figure A-3.2.3.1.(4). The modifications permitted by Article 3.2.3.12. would be applied, if applicable, to the area of unprotected openings derived from Sentence (4).

Accessible and Universal Washrooms

 A-3.8.2.8.(1) to (4) Accessible and Universal Washrooms. 

A universal washroom is an accessible space providing privacy for one person and their care attendant(s), regardless of their gender. It is intended

that a universal washroom be available in close proximity to each bank of washrooms in a floor area. In the case where only one water closet is provided, a universal washroom would satisfy the requirement of Sentence 3.8.2.8.(1).

Figure A-3.8.2.8.(1) to (4) presents examples of washroom floor plan combinations that include men's, women's, accessible and universal washrooms.
