allowed me (and the previous CIR recipient) to move the TSTAT set-points in the

simulating ventilation-only energy. Seems like a sneaky work-around, but by
doing this in <u>both</u> models it’s treated as an allowable measure.<o:p></o:p></span></p>

<p class=MsoNormal><span style='font-family:"Calibri","sans-serif"'>The
warehouse I am looking at is a rectangular building, just under 1.5 million sf
and with a ceiling height of 41 ft. Maximum occupancy is 50 people mostly in
12,000 sf of administrative offices with 10 ft ceiling. Why maintain the entire
mass of air occupying the space volume in the warehouse at 75 deg F in summer
and 70 deg F in winter? Can the proposed warehouse model use just ventilation
and save energy. The percent energy savings for LEED certification is enormous.
Mechanical floors are heated (to prevent pipe freezing) and ventilated.
Underground parking is ventilated. Does ASHRAE Std90 for commercial buildings
include industrial buildings (steel plants)? The definition only mentions area
and number floors. I might have got it wrong. I have only worked on
commercial that house people.</span><o:p></o:p></p>
