<DIV><FONT face=Arial size=2>As I've stated in a previous message, DOE-2.1E in
its various guises has been used extensively in China. I've recently
completed an ASHRAE paper that compared DOE-2 to measured data for the first
LEED Gold building in China - the US-China Agenda 21 demonstration
energy-efficient office building that was a collaboration between USDOE and
China Ministry of Science and Technology. But validation of DOE-2, or any
simulation program, against measured data is almost entirely a matter of
matching results by adjusting the inputs. Only very detailed measurements would
be able to discern possible discrepancies in heat flows or predicted indoor
temperatures or loads. Leaving aside the issues of inputs and
weather data, I cannot think of any intrinsic thermodynamic reason why
DOE-2 (or any other physically-based thermal simulation program) would be
inappropriate for China.</FONT></DIV>

China<BR><BR></FONT></DIV>
<DIV>Dear all, </DIV>
<DIV> </DIV>
<DIV>My question is about eQuest. I wander if eQuest could be used to to
energy simulation for a highrise residential building with PV system? Are
there any published paper on this?</DIV>
<DIV> </DIV>
<DIV>my second question is about the validation of the program. Has anybody
used eQuest in semin tropical climate in China (or similar area like
hongkong) and validated their result? Jeff suggested that eQuest shares the
same core as DOE-2 which has been extensively used in China and I can get
validation from the DoE. Any suggestion is highly appreciated. </DIV>
<DIV> </DIV>
<DIV>Your help is very much appreciated.</DIV>
<DIV> </DIV>
<DIV>Best Regards,</DIV>
<DIV> </DIV>

Average hourly statistics for wet bulb temperatures<BR><BR><BR>My
mistake! You are correct that the epw-->csv conversion will
only give DB, <BR>RH, and Dew Point. The alternate route is to
run an annual simulation with<BR>EnergyPlus using the weather file of
interest, select "Outdoor Wet Bulb" as an<BR>hourly REPORT VARIABLE, and
then use the csv output file to generate <BR>statistics. One
could even generate the averages with EnergyPlus by applying<BR>schedules
to the report variable and reporting the scheduled value as
monthly<BR>averages.<BR><BR>Mike<BR><BR><BR>On 25 Aug 2006 at 6:20, Gerald
