The fresh-air inletsabout the horseshoe and under the first balcony were doing their dutywell. The fan in the basement is able to deliver actually the requiredtheoretical quantity of 1,000,000 to 1,250,000 cubic feet an hour, or about1,500 cubic feet to each person in the auditorium. The upper fan canwithdraw this amount at 100 revolutions, while it could easily run to 200when speedy change of air might be desired. In conclusion, I would say that I think much better results could beobtained if the exhaust fans were run at a higher rate of speed than onthe evening in question. A considerable amount of energy is waste
