Input data values are those recommended by the appropriate IEA task experts, except where specific to the Swedish Case Study.
The weather data used is Boston, Madison and Copenhagen which does not fit very well with the local climate in Uppsala. Therefore the reference case in the simulations has a collector area of 20,000 m^.
A problem with the modelling is that the inlet and outlet pipes in the model are fixed to the top and the bottom respectively. This means that the distribution system will work with an unnecessarily high temperature and that the stratification will be partially spoiled due to different return temperatures from the houses.
