Key contribution

Thanks to its unique innovative technology while contributing to green building, SageGlass improves occupants’ well-being by enabling solar passive heating in winter, while limiting summer thermal discomfort caused by direct sunlight exposure.


To ensure that appropriate thermal comfort levels are achieved through design, and controls are selected to maintain a thermally comfortable environment for occupants within the building.

Requirement summary

A thermal modelling of the building has to be carried out, setting local comfort criteria in line with ISO7730:2005. It needs to include both winter and summer comfort. This modelling is analyzed to define the temperature control strategy of the building (heating, cooling systems): zoning, level of occupant control, interaction within the different systems, and information of users

Our contribution

Through its efficient insulation and dynamic solar control properties, SageGlass products deliver thermal comfort both in winter and summer. SageGlass can particularly help to reduce thermal discomfort due to direct sunlight exposure. Note that it should be mounted in a high airtight framing system with adequate insulation properties.

Entire sections of SageGlass windows, specific windows or individual zones within a single pane can all be tinted according to occupants’ desires and space requirements, either through automated or occupant control.
