Question

How should a skylight shaft wall be modelled in HOT2000When it is located in a roof assembly whose depth is filled with insulation?

A) Wall regardless of its slope
B) Glass block configuration
C) Window regardless of its slope
D) Can be ignored

Answer 1

In HOT2000, a skylight shaft wall is best modeled as a window regardless of its slope, reflecting its glazing properties and impact on energy performance similar to that of a window.

Step-by-step explanation:

When modeling a skylight shaft wall in HOT2000, especially one located in a roof assembly filled with insulation, it would be most accurately represented as a window regardless of its slope (Option C). Skylights are typically described in energy modeling software like HOT2000 in terms of their glazing properties and geometric configuration, which are similar to windows rather than walls. The skylight shaft allows light to pass through, like a window, and has thermal properties due to the glazing that affect the energy performance of the building. The orientation and slope of the skylight may also affect solar gains, much like windows do.
