Daylighting is the transmittance of natural light into a space through openings to reduce or eliminate electric lighting. The art and science of proper daylighting design is more than just adding windows or skylights to a space. It is the careful balancing of heat gain and loss, glare control, and variations in daylight availability.




Purpose
To create a visually stimulating and productive environment for building occupants, while reducing as much as one-third of total building energy costs.

Green Building compliance requirement

LEED India:
Achieve a minimum Daylight Factor of 2% (excluding all direct sunlight penetration) in 75% of all space occupied for critical visual tasks.

IGBC Green Homes:
Achieve a minimum glazing factor of 2% in each of the living spaces for atleast 50% of the total floor area of all regularly occupied spaces which include kitchens, living rooms, bed rooms, dining rooms and study rooms. Additional points can be achieved if 75%, 85% or 95% of the total floor area achieves a minimum of 2% glazing factor.

IGBC Green Factory:
Achieve a minimum average daylight factor of 2% for at least 50% of the total floor area of all regularly occupied spaces. Additional points can be achieved if 75% or 95% of the total floor area achieves a minimum of 2% average daylight factor.

BREEAM (U.K)
At least 80% of net lettable office floor area is adequately daylit with an average daylight factor of 2% or more.
