[Bldg-sim] ASHRAE 90.1 building rotation reasoning

[Cramer Silkworth]

Christopher,
 
One of the addenda to 90.1 removes this requirement and the use of
addenda is accepted by USGBC, so you don't need to waste your time.

Subject: [Bldg-sim] ASHRAE 90.1 building rotation reasoning



What is the original reasoning behind the ASHRAE 90.1 Appendix G
building rotations through 0, 90, 180 and 270 degrees?

 

If the building is only going to have one orientation, why go through
the trouble of rotating and averaging the building values when there
should be only one base case?

 

Are steps being taken by ASHRAE or the energy modeling community to
change this?

 

Thanks kindly,
