See below how Design glass solutions by Saint-Gobain can contribute to LEED V4 criteria: Daylight.
Glass is the most contributory material to daylight thanks to its transparency. Spearheading sustainable design, our wide range of interior solutions can be used as walls, partitions, doors, floors or even as decoration with mirrors by reflecting the light.
To connect building occupants with the outdoors, reinforce circadian rhythms, and reduce the use of electrical lighting by introducing daylight into the space.
The first requirement consists in providing manual or automatic (with manual override) glare-control devices for all regularly-occupied spaces.
Three options are proposed to measure the daylight in the building which has to meet specific thresholds:
- By simulating, evaluate the spatial daylight autonomy and annual sunlight exposure (2 or 3 points);
- By simulating, evaluate the illuminance levels (1 or 2 points);
- Measure the illuminance level when the building is finished (2 or 3 points)
Read the detailed requirement for Daylight
Thanks to its transparency, glass used in doors and partitions increases light input and maximizes autonomy without artificial light.
When selecting interior glass, in regard to daylight criteria, it is important to consider light transmission that corresponds to the percentage of light passing through the glass.
- With higher light transmission (up to 91%) than traditional glass, our clear float glass PLANICLEAR and DIAMANT help create bright interiors;
- For unimpaired vision through the glass, VISION-LITE II anti-reflective glass can be a good solution. It combines very high transparency levels (more than 90% visible light transmittance) with very low residual reflectance (approximately 10 times less reflection than conventional glass) to provide perfect vision of objects. It is ideal for applications in internal partitions, television studios, sound booths, protective screens, etc.;
- Glass can even be used as flooring (LITE-FLOOR) and enables light to enter the building from the top and permeate through all floors; and
- As a decoration, mirrors contribute to daylight by reflecting sunlight. With its ability to capture and reflect light, MIRALITE PURE is ideal for use in all rooms in the home, but particularly where there is a need to compensate for a lack of light or space.
