Hi Joe,<div><br></div><div>1a I understand. But we are looking at a 1b location (Hot/ Dry).

<div><br></div><div>Am I missing something fundamental about the physics of non-extant economisers?</div><div><br></div><div>Chris<br><br><div class="gmail_quote">On Thu, Jun 13, 2013 at 11:54 AM, Joe Huang <span dir="ltr"><<a href="mailto:yjhuang@whiteboxtechnologies.com" target="_blank">yjhuang@whiteboxtechnologies.com</a>></span> wrote:<br>

I'm more agnostic about this. ASHRAE Climate Zone 1 (Miami) is very
hot as well as humid. Hopefully, there was some analysis done
showing that economizers are not cost-effective under such climate
regimes. <br>

Is it just me, or is does it seem terrifically wasteful that a
climate 1 building doesn't require an economiser? Or am I missing
something?
