Energy Monitoring - Objectives vs Results
MetadataShow full item record
Universities, hospitals and similar institutions as well as manufacturers and plants have implemented programs of utility submetering. Submetering of utilities is defined as the measurement of energy at or near the point of use as opposed to gross measurement of energy coming into a building or facility. Without exception, the results achieved have met or exceeded expectations. Most of the programs are continuing in an expanding mode. Results of improvements to the utility distribution system can be measured in reduced usage and improved efficiency after submetering is in place. Networking of this monitoring system further enhances information collection and analysis. When other factors such as outside temperature and time of day are included in the data base, an emerging picture of energy usage for an entire facility is developed. A summary of highlights from several of these programs will be discussed in terms of what has been and is being accomplished. The importance of the commitment of both management and technologists/operators becomes evident as the initial objectives are achieved and expanded to match the innovation and skills of these professionals. The programs highlighted represent a group of progressive companies and institutions which have joined a "savings club." We are familiar with the savings clubs based on the investment of capital, depending strictly on interest to generate funds for us. The kind of savings clubs to be discussed in this paper joins capital with the more important human element to generate significant savings in deferred energy expenses. Steps necessary to "join the club" are listed and the ingredients of commitment and planning are discussed.
