Paul,<br><br>Be aware that your request and my response (which ASHRAE's <br>Hammerling forwarded to you) was considered an "unofficial <br>interpretation".<br><br>Here is a note that I have included on unofficial <br>interpretations in the past:<br><br>"NOTE: An unofficial or personal interpretation is a written <br>explanation of the meaning of a specific provision of a <br>standard or guideline in response to a written request. <br>While every effort has been made to ensure its accuracy and <br>reliability, it is advisory and provided for informational <br>purposes only, and in many cases represents only one <br>person’s view. It is not intended and should not be relied <br>on as an official statement of ASHRAE."<br><br>A formal interpretation request to ASHRAE 90.1 takes much <br>longer and is voted on by the committee.<br><br>So please don't consider my quick note as "ASHRAE's Answer".<br><br>Jason<br><br>On 12/1/2010 11:22 AM, Paul Diglio
