Technology (NIST) did an extensive study documenting a greater than 40% natural
gas savings and a greater than 25% electricity savings across the nation for
building energy consumption if buildings were uniformly constructed with air
barrier systems installed.&nbsp; They evaluated 116 existing buildings and
computer modeled several different building types.&nbsp; The purpose of their

that Appendix G to ASHRAE 90.1 allows you to change the air leakage rate off

that you could claim LEED points for the corresponding energy savings.&nbsp;
However, an architect at a presentation I did said you could not do that under
the LEED and ASHRAE requirements.&nbsp; (I know the models will do it, because
