Languages: English

Claims procedures for design of ventilation and air flow systems are energy wasteful. Cause lies in their methods and technical bases and influence of other factors entering into final systems choice (particularly economics). Discusses outside air requirements. Concludes ventilation rate can be lowered 45% to 50% if higher humidities are used. Proposes new standards based on fact that ventilation rate is independent of air space per person. Analyses air distribution systems and sub-systems in terms of minimum energy requirements. Treats energy saving by velocity reduction and savings expected with introduction of new ASHRAE definition of effective temperature.
