Abstract: This paper presents the results of a sensitivity analysis performed on a real office building of 3500 m² coupled with micro-CHP system in addition to a gas boiler and a hot water storage. We compare equipment performances for four envelope characteristics corresponding to four construction periods (based on building thermal regulations) in France (before 1980 to 2012). The results obtained by simulating the building combined with the heating plant model in Dymola/Modelica environment show good correlation between the electrical peak load and production (most of the time, the consumption is higher than production). With the micro-CHP, the production plant satisfies correctly the thermal needs and the temperature is comfortable for all office floors. These results are encouraging and can be used by practitioners and engineers to design, to size and operate efficiently micro-CHP.
