Subject: [Equest-users] ASHRAE baseline building rotation<o:p></o:p></span></p>

<p class=MsoNormal>ASHRAE Appendix G states that the baseline building glazing
should conform with the 90.1 minimum standards. This is differentiated between
north and other orientations.<o:p></o:p></p>

<p class=MsoNormal> <o:p></o:p></p>

<p class=MsoNormal>Therefore my baseline building has low-performance glass on
north facade and higher-performance glass on other facades.<o:p></o:p></p>

<p class=MsoNormal> <o:p></o:p></p>

<p class=MsoNormal>My question is when rotating the baseline building during
performance rating method, should the glazing be re-assigned? Ie) should each
rotation meet 90.1 standards or only when the building is in its original
orientation.<o:p></o:p></p>

<p class=MsoNormal> <o:p></o:p></p>

<p class=MsoNormal>I’m sorry this isn’t a strictly an equest question
(equestion?) but I’m sure lots of you have encountered the same problem.<o:p></o:p></p>

<p class=MsoNormal> <o:p></o:p></p>

<p class=MsoNormal>Cheers<o:p></o:p></p>
