Exergy analysis complements energy analysis by allowing the comparison of different energy sources and flows in buildings, and also by quantifying the effects of working temperatures. This seminar will focus on the applications of exergy analysis to different aspects in buildings, such as domestic hot water, building envelope, and heating and cooling systems together with the effects of auxiliary components. The seminar will identify the benefits of using exergy analysis to achieve a global optimum with respect to energy, performance and resource use.
