Subject: [Equest-users] ASHRAE baseline building rotation<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-GB>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></span></p>
<p class=MsoNormal><span lang=EN-GB> <o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-GB>Therefore my baseline building has
low-performance glass on north facade and higher-performance glass on other
facades.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-GB> <o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-GB>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></span></p>
<p class=MsoNormal><span lang=EN-GB> <o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-GB>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></span></p>
