I am trying to model the effects of thermal mass in the external walls on space conditioning efficiency. Does eQuest take into account solar gain on the building walls? Why I ask is that I've noticed that increasing thermal mass in the walls, (while maintaining the same R-value), has no effect on the heating load and very little on the heating demand. I also noticed that there doesn't seem to be a way to specify external shading from trees, adjacent buildings, etc.<o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>Peter<o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div></div></div></body></html>
