<p class=MsoNormal><span style='color:#1F497D'>In my experience you do
not increase the baseline energy model as you are being awarded (gaining that
point) when you achieve the ventilation credit. There are a few similar
situations in LEED where by achieving one credit will prevent you from achieving
another but this happens to everyone so it works out to be somewhat fair. <o:p></o:p></span></p>

<p class=MsoNormal>There is a credit in LEED (EQc2.0) that involves increasing
the required ventilation rate by 30%. In trying to achieve this credit,
the amount of energy would have to increase to condition that additional 30%
OSA. Does anyone know if you are supposed to increase the baseline energy
model’s ventilation rate so it has the same ventilation rate as the proposed
building? Thank you in advance for your help.<o:p></o:p></p>
