High Performance Roof Daylighting

Roof daylighting elements and architectural roof glass are striking and desirable building features that historically come at a high cost – leaks, energy loss, thermal discomfort, and condensation issues. Next generation roof glazing is addressing these issues and developing roof glass elements designed to be thermal-bridge-free, and suitable for high performance and Passive House envelope needs. Fenestration of all kinds requires special attention, but failures in roof glazing can unravel the thoughtful planning put into the rest of the building. Potential for thermal bridging, overheating, cold air convective currents and air or water leaks can dampen or destroy the gains of free daylight and visual comfort. Lamilux and Fakro skylights are thermally continuous and exceptionally airtight. With continuously insulated and thermally broken frames and triple layer insulated glazing, these skylights are ideally suited for high performance, net zero, and Passive House building enclosures. Their respective assemblies and accessories also allow for simple detailing for connections of the control layers in the surrounding roof assembly. In this presentation we cover design considerations for roof daylighting of all types and sizes – commercial or residential, flat or pitched roof, light tube or wall-to-wall roof glass. Proper integration and design decisions result in roof daylighting that addresses energy, light, health, ventilation, comfort, and overall wellness of both occupants and the longevity of the building envelope.
