Key contribution
SageGlass can be installed in operable windows to provide fresh air while managing transmitted solar heat and light simultaneously.
Aim
To increase the supply of high quality outdoor air and promote a connection to the outdoor environment by encouraging occupants to open windows when outdoor air quality is acceptable.
Detailed requirement
Part 1: Full Control
Every regularly occupied space has operable windows that provide access to outdoor air and daylight.
Part 2: Outdoor Air Measurement
Outdoor levels of ozone, PM₁₀, temperature and humidity are monitored based on the following requirement, and data collected is made available to the building occupants: a data-gathering station located within 1.6 km of the building.
Part 3: Window Operation Management
If the outdoor air measurement system indicates that outdoor air either exceeds ozone levels of 51 ppb or PM₁₀ levels of 50 μg/m³; has a temperature of 8 °C [15 °F] above or below set indoor temperature; or has a relative humidity above 60%, then one of the following is used to discourage occupants from opening windows:
- Software on occupants' computers or smartphones.
- Indicator lights at all operable windows.

Our contribution
SageGlass can be installed in operable windows to provide fresh air while managing transmitted solar heat and light simultaneously. SageGlass’ ability to modulate the visible light and solar heat may allow for greater design flexibility and increased window to wall ratio.
