o Provide means to transfer heat from the core of a large building to the cool periphery needing heat

Heat generated by people and activities in the central core area of large buildings is often in excess of what is needed to provide heating needs. If this excess heat is ventilated to the outdoors or is absorbed by refrigeration systems at a time heat is supplied to the colder periphery changes could be considered to transfer this heat to where it is needed and when it is needed by modifying existing systems or their

controls.

The energy savings would amount to the equivalent

of that energy that would have been rejected to the outdoors.

o Install automatic door closers

Open doors represent a major heat leak. People tend to

save the energy that would normally be lost. The savings are difficult to quantify but it is estimated that it is worthwhile. Some data are available in the handbooks of the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE), New York, N. Y.
