Expanding the exergy concept to the urban water cycle [PDF]

, 2009
The world is urbanizing fast and this increases the pressure on available resources. In a world of cities, it is therefore crucial to take a new look at the way urban systems function: where do the resources come from and where do the wastes end up?

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
