The purpose of this study is to investigate the elements of satisfaction-dissatisfaction possessed by total energy systems purchasers with particular reference to those problems which can arise following proof of specific feasibility for a particular building complex. Specifically, this study is concerned with the following elements of the problem: (1) What factors were of influence in arriving at the decision to purchase a total energy system? (2) What elements of satisfaction-dissatisfaction are possessed by total energy systems purchasers toward the economics of the system? (3) What elements of satisfaction-dissatisfaction are possessed by total energy systems purchasers toward the performance of the system? (4) What general attitudes are held by the purchasers indicating satisfaction-dissatisfaction with the system? The universe consists of those buildings possessing an on-site energy system in northern Illinois which are not directly concerned with either the sale of natural gas or natural gas equipment. The personal interview procedure was employed with telephone interviews being submitted only in those cases where the former was impossible. Since the pamphlet used for formulating the sample was published by Northern Illinois Gas Company, only those buildings being serviced by this firm were included in the universe. There are actually two sets of factors of consequence during any total energy consideration. The first set of factors, dealing with the development of interest in the system, consists primarily of grievances against the electrical utility previously serving the total energy customer. While the second set, concerned with the actual purchasing decision, is based on an expectation of greater savings. In response to questions dealing with investment advisability, savings vs. effort, and the reliability of the economic forecast procedure, total energy system purchasers have shown that they are quite pleased with the economics of the system. Similarly, engine noise discomfort, sufficiency of generating capacity, reliability of prime and reserve generating equipment, and other possible performance problems were shown to be of no great significance. The willingness of the majority of the respondents to again substitute on-site energy production for purchased power indicates the degree of satisfaction possessed by total energy system purchasers.
