Hello,

ASHRAE 90.1-2004 Appendix G has a clause pertaining to self-shading of the
baseline building, but there does not seem to be any explicit direction
regarding shading from other objects beyond the building envelope (trees,
buildings, etc). Should the base case be modeled as being impacted by
adjacent buildings or other objects? Would this be different for a new
building versus an existing building that is being gutted?

Thanks
