12th International Symposium on District Heating and Cooling

The <strong>12th</strong> <strong>International</strong> <strong>Symposium</strong> on District Heating and Cooling,September 5 th to September 7 th , 2010, Tallinn, EstoniaModelling of a system gives one side of the truth, asdoes interviewing the actors involved. When combiningthe methods there is a possibility of getting a better anddeeper understanding of the actual potential forcooperation. The historical and social aspects cannotbe neglected; they can in many cases explain whypotentially beneficial cooperation is or is not done,while modelling can show the actual potential.7. ACKNOWLEDGEMENTSThis article has been carried out in two PhD projects inthe Energy System Program, financed by the SwedishEnergy Agency. The authors would also like to thankJenny Palm (Linköping University) and Louise Trygg(Linköping University) for valuable comments on thepaper.8.
