3.1.1 Impacts on sunlighting
- Borough by-laws must mandate that a structure that
exceeds the street height in an identified area on the attached map entitled
“Areas
of Tall Buildings ” (see Appendix
A) should, at the equinox, provide sunlight for at least:
- 150 consecutive minutes between 12 pm and 3 pm on
east-west vibrant streets identified on Map 2.3.3, entitled “Key Roadways of
the Centre”;
- 150 consecutive minutes or a minimal duration of
sunlighting resulting from maximum street heights (as measured in metres) on
north-south vibrant streets identified on Map 2.3.3, entitled “Key Roadways
of the Centre”;
- 90 consecutive minutes between 12 pm and 3 pm on
east-west streets other than the vibrant streets identified on Map 2.3.3,
entitled “Key Roadways of the Centre”;
- 90 consecutive minutes or a minimal duration of
sunlighting resulting from maximum street heights (as measured in metres) on
north-south streets other than the vibrant streets identified on Map 2.3.3,
entitled “Key Roadways of the Centre”;
- 8 consecutive hours between 8 am and 6 pm on at least 50%
of the surface area of parks and public spaces – a duration established
in view of the maximum permitted heights in metres and the development
potential of adjacent land, as evaluated including and excluding the project
in question.
- The study of the impacts on sunlighting of a building
located in an area identified on the attached map entitled “Areas
of Tall Buildings
” must
be conducted in view of the following parameters:
- The evaluation of sunlighting must be conducted
including and excluding the project;
- The evaluation of sunlighting must consider the
development potential of adjacent land, determined by the maximum heights of
buildings on the street;
- The period of sunlighting to be considered in evaluating
the impact on a street must correspond to the duration of the trajectory
of the sun from one side to the other of the surface area covered by the
street, such that at least one sidewalk receives sunlighting.
