Daylight in Green Star focuses on delivering well-lit spaces that provide high levels of visual comfort to building occupants. Points are awarded when project teams can demonstrate that a specified proportion of a nominated area receives high daylight levels.
Daylight Factor can be used as follows:
"High Levels of daylight are deemed to have daylight factors above 2.0% for all spaces, except living rooms and dining rooms in residential primary spaces, where the threshold is a 1.5% daylight factor."
When calculating the Daylight Factor, Green Star recommends using either a CIE overcast sky or a CIE uniform sky, and the grid is either at the finished floor level or 720mm above FFL.
Daylight Autonomy can be used as follows:
"High Levels of daylight are deemed to have at least 160 lux due to daylight during 80% of the nominated hours."
Green Star recommends that simulations must be completed for at least every hour during the Nominated Hours.
To meet the requirements of Daylight for Green Star, the Purpose of the must be defined within the model for that Space to be selected for assessment. In this case, the 'Living Spaces' must be defined with a . Once defined, the is used to nominate the , , and before running a simulation. For the Metric, inputs must be configured per Green Star's requirements. See your Greenb Star documentation for up-to-date information.
