Small-scale Co-generation for Building Applications - Energy Demand Analysis At Demonstration Site and Optimal Sizing of the Chp Plant

Aspects of using the small‐scale combined heat and power modules in buildings is presented in this paper. At first the problems of energy demand analysis, which is the key point of a co‐generation plant sizing procedure, are discused. Then the demonstration project of a small‐scale co‐generation plant is presented. The plant is fuelled with natural gas, and it supplies energy to a group of three different buildings. Basing on this case, the problems of optimal sizing of a small‐scale CHP plant for a building energy supply system are presented and discussed. Calculation procedures are shown together with the results of sample analysis. The factors influencing the final configuration of the system are indicated.
