See below how Glass façade & windows by Saint-Gobain can contribute to LEED V4.0 criteria: Optimize Energy Performance.
Saint-Gobain offers a wide range of high performance products that can be configured thanks to the Calumen Live tool, so that the optimized glazing for all climates can be designed and green architecture delivered.
To achieve increasing levels of energy performance beyond the prerequisite standard to reduce environmental and economic harms associated with excessive energy use.
The project’s energy performance is assessed and compared to the baseline. Points are awarded according to the percentage of improvement between the two (see table below).
Read the detailed requirement for Optimize Energy Performance
As part of the building envelop, the glazing firstly minimizes energy needs and mainly influences three types: heating, air
conditioning and lighting. Glazing properties directly impact these areas as follows:
- For heating, a low emissivity glass (also called “low-e”) allows for the retention of heat inside the building and a better glazing thermal insulation (also called the “Ug value”) can limit heat loss;
- For air conditioning, the solar factor (also called the “g value”) has to be considered; and
- For lighting, thanks to an important light transmission (in %), natural light can enter into the building.
Glazing offers the full potential to create performant solutions that are directly linked to the context of use, such as the geometry and geographical localization of the building, its window sizes and orientations. Thanks to coasted and insulated glass with their respective properties and our performance simulation tools, we can create the optimized glazing for your project.
Below you will find some examples of glazing configurations according to the context of use (an extract of the wide range of solutions that we can provide):
COOL-LITE XTREME 70/33
An extremely high selectivity solar control coating featuring advanced thermal properties to ensure both daylight and thermal comfort.
New generation of Saint-Gobain low-E (low emissivity) glass which combines aesthetic, thermal insulation, solar gains and natural light.
A Low-Emissivity glass combining the highest level of light transmission with a very low Ug-value, to reduce heat losses to a minimum.
COOL-LITE XTREME 60/28
High selectivity solar control glass with advanced thermal insulation properties.
