<p><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>Hi All,</span>
<br>
<span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>I am trying to
do an energy modeling using ASHRAE 90.1 performance rating method for a
building in Mexico City, Mexico. I am trying to figure out where Mexico City
would fall under for the climate zone. Table B-3 tells me the Zone number but
it does not tell me the Climate Type (A, B or C). So, I followed the Table B-4.
This does not classify between A or B for zone 3 based on the degree days. I
also went through Appendix B2 (Major climate type definitions) page 109. I was
able to climate that it is not Climate Zone type C. But in order to verify
whether I am in B, I need to know the annual precipitation. Where do I get this
value from? Will it be in ASHRAE or any other standards? I searched in the
website and I am getting different values for Mexico city precipitation.
Depending on this I would either fall in A or B. Would like to follow some
standards rather than searching in the website. </span><o:p></o:p></p>
<p><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>I am writing
this story because I need to figure out whether my baseline would require an
economizer or not. Zone-3A does not require an economizer where as Zone-3B
does. </span><o:p></o:p></p>
<p><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>Any guidance
will be appreciated.</span> <br>
