<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>I am curious as to how to break up the thermal blocks in
eQUEST. eQUEST allows each zone to be broken down into different space types by
percentage. According to Appendix G, Table G3.1, Section 7, three conditions
have to be met in order to clump thermal blocks together: the space use classification
has to be the same, they have to have exposure to one façade (or a façade with
a <45 deg bend), and they have to be served by the same type of HVAC equipment.
When a large zone is created based on the area being conditioned by a HVAC
system, breaking down the spaces by the percentage doesn’t meet the three
conditions required. If spaces are broken down according to the ASHRAE
requirements, it often leads to a large amount of zones. If all zones have at
least 1 hr. of unmet heating or cooling, and there are greater then 300 zones,
the model will exceed the amount of hours allowed. Any suggestions on an
approach on zoning to simplify the model that meets ASHRAE requirements?<o:p></o:p></span></font></p>
