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.
