62. Daylight modeling
Exposure to appropriate amounts of natural light provides a connection to nature that reinforces circadian rhythms and reduces dependence on electricity for artificial lighting. Buildings can be designed to ensure that people who spend the majority of their time indoors still have access to daylight.
This feature requires that individuals inside a building receive ample exposure to natural sunlight.
Lighting simulations demonstrate that the following conditions are true:
If sound masking systems are used, sound levels fall within the following range, when measured from the nearest workspace:
