Exergy Analysis in Buildings [Elektronisk resurs] : A complementary approach to energy analysis

, 2009
Though mandatory to be pursued, improved energy efficiency is not the only target to reach. The quality of energy has to be assessed as well. Most of the overall energy use in residential building is for low temperature heat, i.e. temperatures relatively
