Rotating Existing Building Renovations

To meet Appendix G requirements, you still need to rotate the baseline in the model. The rewards projects with good orientation, regardless of the project's ability to influence the outcome. Further, I would argue that even a gut reno should be considering orientation. One might consider different glazing types or shading schemes depending on orientation. Even program elements might be impacted by orientation. Areas with high process loads might not need the winter passive solar afforded by by a south exposure, etc.

We too have this experiance but unfortunately no answer. The intensions in LEED is truly missLEEDing as we can not affect the Baseline Building electricity use, the major factor, I think, to the difference between 47 % and 22 % in your exampel, Michael. In Ashrae handbook it is stated that the calculations can be based on energy cost OR energy performance so maby therefore we can use energy performance in LEED instead of energy cost, Chris??

LEED specifically requires use of energy cost, for better or worse.
