Exclude buildings (Heat Stress Overlay)

Icon	Attribute	Unit	Range	Description	Default value
	EXCLUDE_BUILDINGS	boolean		Whether the results of buildings should be excluded from the avg sky-view and PET results.	1

The results from calculations at the locations of buildings may be skewed or lead to incorrect assumptions of how the calculated values should be interpreted. The DPRA Heat Stress Module does not incorporate buildings (walls and roofs) in the calculations, as the model utilizes a terrain elevation of 1.2 meters; the effects of higher (green) walls and roofs on the DPRA model are currently not fully documented.

To prevent these values from affecting further calculations, or inciting questions around interpretation, it is recommended to exclude buildings from the end-result.

If buildings should be included, set this attribute accordingly. Buildings are then added to the elevation model, and heat stress is calculated on them as well.
