Remember that the wider the corridors are, the less footprints you will be able to put in place. So less ROI as far as space is concerned.
Lock the cold corridor down as much as you can (place doors and roofs), more than 100cm rack depth is -in my opinion- a waste of space and air pressure. Keep the pressure under (the floor) as high as you can and put blinds in every unused unit.
Furthermore, let customers pay for used power instead of default power use (lets them buy low voltage units).
