return to Sustainable Window Design
This documents our experience in designing, building and operating the sustainable window design at the Green Garage.
- Goals:
- Provide 80% of the interior lighting with natural daylight.
- Provide adequate natural ventilation to minimize the need for mechanical ventilation whenever possible.
- Provide a sense of security and well-being within the living building, while providing an attractive and inviting addition to the community.
- U Factor (Thermal) < 0.30
- Window -to-Wall Ratio (WWR) < 27%
- Solar Heat Gain Coefficient (SHGC): E = .30; W = .30; N = .30 ; S = .55; Skylight = .55
- Visual Light Transmittance (VLT or VT); E = .50; W = .50; N = .50; S(up) = .70; S (view)= .50; Skylight = .70
