<div class=Section1>
<p class=MsoNormal>I have noticed that eQUEST does not accurately determine the
cooling and heating loads when rotating the building 180 degrees using the Azimuth
feature under the building properties in the detailed edit mode. I created and
attached a file where there are two classrooms. One classroom faces north and
one faces south. <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>When I run the simulation I get the following results: <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>North Facing: Space Cooling: 4.1 MBTU, Space Heating: 21.9
MBTU<o:p></o:p></p>
<p class=MsoNormal>South Facing: Space Cooling: 4.3 MBTU, Space Heating: 18.9
MBTU<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>When I change the orientation 180 degrees, the results are:<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>North Facing: Space Cooling: 3.9 MBTU, Space Heating: 23.0
MBTU<o:p></o:p></p>
<p class=MsoNormal>South Facing: Space Cooling: 3.6 MBTU, Space Heating: 18.1
MBTU<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>When I rotate the site 180 degrees the north and south
facing energy consumption is different (they should be exactly the same). Also,
the space cooling does not make sense because the building’s weather file
is Dayton Ohio and the south facing classroom should use more cooling than the north
facing classroom.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>This makes me assume that eQUEST has a problem with building
rotation in the detailed edit mode. <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Please check to see if I am assuming this correctly because
this will affect every LEED project.<o:p></o:p></p>
