THE POTENTIAL FOR ENERGY CONSERVATION IN THE CONSTRUCTION OF CIVIL WORKS PROJECTS
Abstract
Energy use, by nature of its economic and political impact is becoming a vital consideration. Energy cost now represents a sizeable portion of the total project cost for civil works projects. This study presents an evaluation of civil works projects to determine if a potential for energy reduction or control exists and the nature of possible opportunities for more efficient utilization of energy resources. Using an earth dam project, a method for estimating the energy requirements is demonstrated and the major energy use activities are identified. A scheme for classification of energy use is presented and a method for establishing the energy content for a construction end product or "an in-process component" of the construction end product is explained and illustrated by example. Based on the estimate of energy requirements for the earth dam project, the activities representing the most intensive use of energy, earthwork operations, are examined in greater detail to determine the primary factors affecting energy use and productivity. The possibility of a correlation between energy use and productivity is evaluated. Methods for coordination and control of the factors affecting energy use and productivity are discussed. Various opportunities for energy reduction and control applicable to civil works projects are identified and evaluated. Further research efforts necessary to develop the potential for energy conservation in the construction of civil works projects are presented and briefly explained.
