font-family:Arial'>We’ve received a nice boost in some models in <st1:place
w:st="on"><st1:country-region w:st="on">Canada</st1:country-region></st1:place>
lately as the Proposed and Baseline designs only need to have the same amount
of outdoor air in the <u>breathing zone</u> under CaGBC Rules. Meaning
that if your baseline design is VAV Reheat and your proposed design is chilled
beam and baseboard heating then your proposed design will have to condition somewhere
in the range of 40% less outdoor air due to higher zone effectiveness and
system efficiency. It makes a lot of sense to me and becomes a significant
energy savings measure. <o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>Is this allowed by the USGBC or by ASHRAE? I just read
in 90.1 in G.3.1.2.5 that “Minimum outdoor air ventilation rates shall be
the same for the proposed and baseline designs.” That doesn’t
specify whether they mean in the breathing zone or outdoor air intake but I
think most assume it to be the outdoor air intake.<o:p></o:p></span></font></p>
