NC-2009 EAp2: Minimum Energy Performance
Hello everyone, happy Friday!
Should a Clerestory Side-light be considered a window? Not sure why am thinking it could be considered as a Skylight but thought to confirm anyway. Thank you in advance.

See the definition of "skylight" and "vertical fenestration" in Chapter 3 of the standard. It is likely a vertical fenestration (i.e. window).
skylight: a fenestration surface having a slope of less than 60 degrees from the horizontal plane. Other fenestration, even if mounted on the roof of a building, is considered vertical fenestration.
vertical fenestration: all fenestration other than skylights. Trombe wall assemblies, where glazing is installed within 12 in. of a mass wall, are considered walls, not fenestration.
