61. Right to light
Psychological health is benefitted greatly through exposure to adequate levels of sunlight. Proximity to large windows, outdoor views and daylight in indoor spaces are some of the most sought-after elements of design. As such, buildings should utilize daylight as a primary source of lighting to the greatest extent possible.
To ensure that daylight is maximized within buildings, this feature sets minimum dimensions for window openings, and minimum distances from windows to regularly occupied spaces.
Part 1: Lease Depth
The lease depth (distance between the building core and the exterior façade) maintains the following dimensions:
a) Does not exceed 7.5 m [25 ft] for 75% of the area for all regularly occupied spaces.
Part 2: Windows and Workspaces
The following conditions are met:
a) 75% of all desks are within 7.5 m [25 ft] of an atrium or a window with views to the exterior.
b) 95% of all desks are within 12.5 m [41 ft] of an atrium or a window with views to the exterior.
