In the Passive House session at the Winter Summit, I spoke about a Massachusetts DOER report that found that meeting the new energy code in MA (passive house or better in most cases) is cheaper for some building types than traditional construction.

BITuser has the advantage of more closely resembling LEEDuser, but it has the disadvantage of looking a little weird in all-caps, as in... Read more
