Skylights

Skylights can provide buildings with daylighting and ventilation. 

Because skylights are located on the roof, they can result in unwanted additional heat in summer and loss of heat from the inside of the building in the winter.

To make skylights more energy efficient, manufacturers use various glazing technologies including heat-absorbing tints, insulated glazing, low-emissivity (low-e) coatings, or translucent insulation material between several glazing layers.
