Guidelines on industrial energy management considered necessary to insure energy availability during the next 10 years were delineated at a symposium on industrial exhaust air held October 6-7, 1977 in Cincinnati, Ohio. The energy problem is placed in historical perspective with conservation as the proposed solution. Practicality in energy conservation, and the many alternatives facing energy designers trying to develop rational energy strategies are focused on. The current demand for energy in the U.S. stands at 74 quadrillion Btu per year. The energy savings from recirculation of exhaust air can come only from the energy spent for space heating in the industrial and commercial sectors. An estimated 50% of such space heating requirements is considered recoverable through recirculation. However, expenditure to remove contaminants from recirculated air may negate the savings in some industries. In space heating, energy loss occurs via conduction losses through walls and windows, infiltration losses resulting from the opening of doors, and ventilation losses resulting from fresh air makeup requirements for buildings. It is concluded that the major target for recirculation technology is in the commercial sector. Based upon a 50% recovery efficiency, the total energy recovery by this technique is slightly in excess of 1 quad or slightly more than 1.5% of the energy consumed in the United States.
