<p class=MsoNormal>Hello, All.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>After perusing Appendix G and the LEED book, I've been
unable to find the answer to this one:<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>If I've got a project that's using a Air-cooled Chiller,
what baseline chiller do I use? Appendix G says to use 2 equally sized
Screw Chillers. But, it doesn't say if these have to be air-cooled or
water cooled. I'd imagine there's quite a benefit to compare with a water
cooled, when you take into account the cooling tower, etc.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Any ideas if this is alright?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
