ventilation air or makeup air, whichever is greater.</span></font></p>

10.0pt;font-family:Arial;color:navy'>Furthermore, if I leave the “Supply
air flow rate” input for each zones as default in the baseline (instead
of entering the supply CFM as in the proposed), I am getting a total
consumption for the baseline to be less than the proposed! I am certainly not
going to let eQUEST estimate the supply flow rates! Remember that I’m
modeling for LEED and I aim for a 15% percent reduction in energy costs, which
was a number I got when I assumed the baseline and proposed cases to have the
same defined supply flow rates as per the ventilation rate procedure (provided
to me by the design team).</span></font></p>
