This is true for some of the other plenum spaces.

Because the room and plenum spaces are close or the same temperature there is minimal or no heat loss between them. You need to go to the plenum space for the heat loss through the exterior roof. If you want the heat loss for the full floor to floor space you have to add the room and plenum losses. The plenum will have some wall surfaces as well.<br>Bruce Easterbrook P.Eng.<br>Abode Engineering<br></span><br>On 06/09/2011 01:46 PM, Jonathan Smith wrote: <o:p></o:p></p><p class=MsoNormal>RE: Detailed Report, LS-F Building Monthly Load Components <o:p></o:p></p><p class=MsoNormal> <o:p></o:p></p><p class=MsoNormal>Why would roof heat losses be zero in a model defined with plenum spaces that have roofs components?
