Templifier Heat Pump, Tony Conigliaro

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

The national energy policy rightly addresses having coal assume a major share of the load carried by gas and oil. However, there is a basic strategy which is uniquely capable of solving much of the dilema. That strategy is to shift from our present oil/gas combustion energy economy to a coal - nuclear electric energy economy....

We can see that electric boilers are non competitive from an operating cost standpoint. But there is another way of applying electricity to the creation of useful heat and that is the heat pump. Several years ago, a Westinghouse feasibility study indicated that an …

Managing In An Energy Scarce Environment, John Amos Oct 1980

Managing In An Energy Scarce Environment, John Amos

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

Present engineering management principles, operations research techniques, and economic theories were mainly developed dealing with only one scarce resource -- capital. Today, the engineer manager must consider another scarce resource -- energy. In the past, energy was never considered a major factor; i.e., equipment was considered a good investment if labor was reduced, regardless of energy cost. Many other managerial decisions are similar; therefore, the engineer manager must understand why many decisions based on traditional techniques may be misleading. The engineer manager must now utilize more complex engineering management techniques instead of evaluating only one factor or using rules of …

Limitations Of Underground Building As An Energy Alternative, A. M. Hanna, N. Evans

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

Building underground offers a potential for a reduction in heating and cooling loads, in comparison to a similar above ground structure. The resulting energy savings over the life of the structure will be beneficial, both in terms of dollars, and in conservation of resources. However, this mode of construction is subject to technical and economic limitations. The limitations, as well as the potential energy saving processes of underground construction, are discussed with special emphasis placed on the soil properties, structural design and construction techniques... which may unfavourably affect the potential energy savings.
