Dynamical modelling of water related energy

Water use and water related energy use is one of the most important energy consumptions in private households.

The contributions are: shower, bath, cloth washing, taps, dish washer, toilets and others.

In 2010 Steven Kenway from University of Queensland, Brisbane, Australia started a collaboration with Eawag with the focus to develop a stationary model to simulate water use and water related energy use in private households and cities.

Kenway, S. J.; Scheidegger, R.; Larsen, T. A.; Lant, P.; Bader, H.-P. (2013) Water-related energy in households: a model designed to understand the current state and simulate possible measures, Energy and Buildings, 58, 378-389, doi:10.1016/j.enbuild.2012.08.035, Institutional Repository

This model gave insight into the yearly water and water related energy consumptions. However for the suppliers the peak flows are crucial. Therefore a dynamical model to simulate the water and water related energy flows in function of time is being developed.
