Key contribution

SageGlass® can dynamically manage solar light and heat. It also contributes to creating thermally comfortable environments in the cooling season. SageGlass® can particularly help to regulate the radiant heat in any space. 


To encourage the establishment of optimal conditions for hygrothermal comfort in cooling mode.

Detailed requirement

Defining/achieving an appropriate temperature level in the spaces, ensuring air speed that does not adversely affect comfort, controlling solar gains and in particular localized discomfort due to heat radiation, controlling of thermal environment by users and hygrometry in sensitive spaces.

Our contribution

  • 8.4.1. Define/achieve an appropriate temperature level in the spaces 
  • 8.4.3. Control solar gains and localised discomfort due to heat radiation 
  • 8.4.4. Control of thermal environment by users 

SageGlass® dynamically manages solar light and heat and contributes to achieving appropriate temperature levels in summer. All in all, SageGlass® helpS to regulate the radiant heat in the space and reduce localized discomfort caused due to solar gains near the windows. 
The user can control the use of SageGlass to manage the thermal environment at any time. SageGlass tint control can be done on an entire row of windows, a single window, or even on areas within the same window. This flexibility is a major asset for the creation of thermal zones within a building.
