We, at the Copernicus institute of sustainable development, are looking for a postdoc to model positive energy districts in the framework of an international project (case studies in Sweden, Norway and the Netherlands) for the next three years. In very general terms the plan is to put together an open source model for such districts and help the case studies to develop plans to become positive energy districts. If you are interested please have a look of the job opening. If you have questions please do not hesitate to asking me ( l.e.ramirezcamargo@uu.nl). If you can think of someone interested, please feel free to redistribute.
