This is a topic that I have explored. Although DOE-2 (the core
engine for eQUEST) does not explicitly solve for the inside surface
temperatures, researchers at EMPA in Switzerland back in the late
90's added a routine to DOE-2.1E to back-calculate the inside
surface temperatures (think of it as doing a heat balance
calculation in reverse). This featured is documented in DOE-2.1E
update package 2 (version 107), but I only have a hard copy of the
report. In 2003, I used this feature to do exactly what Jason is
asking, i.e., calculate<br>
the PMV for naturally ventilated buildings in Egypt. Recently, I've
also used the same feature to estimate the amount of radiant heat<br>
transfer from attics to the conditioned space, something that is
ignored in the weighting factor model in DOE-2. <br>
<br>
The bad news, though, is that this feature has not been carried over
from DOE-2.1E to DOE-2.2, although I've had some discussions<br>
with members of the development team about resurrecting it. <br>
