Evaluation of the computerized utilities energy monitoring and control system installed at the US Military Community at Goeppingen, Germany

Under the provisions of an Interagency Agreement between the US Army and the Department of Energy, Martin Marietta Energy Systems, Inc., through the Oak Ridge National Laboratory, is evaluating the Utilities and Energy Monitoring and Control System (UEMCS) installed at the US Military Community Activity at Goeppingen, Germany. This evaluation relies on examination of existing data and information to determine the effectiveness of the UEMCS. The Goeppingen UEMCS is an integral part of a combined UEMCS/district heating system which includes the UEMCS at Schwaebisch Gmuend, Germany. The system was installed during 1985 and 1986. The UEMCS at Goeppingen and Schwaebisch Gmuend are both well designed, implemented, and maintained. The UEMCS is operated in a supervisory mode with distributed intelligence in local controllers. At present, the UEMCS is operated in a supervisory mode with distributed intelligence in local controllers. At present, the UEMCS at Schwaebisch Gmuend does not have a central computer, but requires only a dedicated phone line to couple with the one at Goeppingen. Though the conversion to district heat has produced the majority of energy savings, the UEMCS day/night setback program also contributes substantially, with additional savings from start/stop programs, such as seasonal switchover, and various temperature control programs. Further opportunities for savings exist in increasing monitoring and control of water usage and connecting the community`s electrical network to the UEMCS, permitting demand limiting and increased power factor control.
