Winter: 70 (+/-2) degrees F. dB when outside temperature does not fall below 11 degrees F. dB. In order to achieve the above stated indoor design conditions, the Landlord shall deliver to the floor through the Building’s supply air shafts at the shaft taps for the Interior Systems conditioned air at 60 degrees F. * and 20,125 CFMs. * when outside air conditions do not exceed 91 degrees F. db and when wattage for lighting and power does not exceed 5.0 Xxxxx/useable square feet and one person per 100 useable square feet.
