Technical FAQs 4

Does skylight slope affect solar heat gain?

The slope of the skylight as it sits on your roof also affects solar heat gain. Lower slopes, for example, admit more solar heat in the summer and less in the winter — something you usually don't want. To figure out the optimal skylight slope for your climate, add 5-15° to your geographical latitude.

Does a south-facing skylight increase solar heat gain?

South-facing skylights provide the greatest potential for passive solar heat gain in the winter, but often allow unwanted heat gain in the summer. The slope of the skylight as it sits on your roof also affects solar heat gain. Lower slopes, for example, admit more solar heat in the summer and less in the winter — something you usually don't want.

Are skylights a good option for solar heat gain?

Those on east-facing roofs provide maximum light and solar heat gain in the morning, while west-facing skylights provide afternoon sun and heat gain. South-facing skylights provide the greatest potential for passive solar heat gain in the winter, but often allow unwanted heat gain in the summer.

Do skylights gain heat during winter?

During winter, the additional heat from skylights is desirable. However, skylights can gain heat during winter as they have less regulations around thermal properties compared to ceilings, floors, and walls. This can lead to solar heat gain issues when summer arrives.
