The aim of this project is to evaluate the possibility to integrate, in terms of energy, the future Nya Studenternas IP and Uppsala University Hospital. The focus is on integration of thermal energy solutions. To cover the cooling demand a seasonal snow storage and the use of cooling machines is studied. For the heat demand a joint heat storage is investigated which is heated partly with the excess heat from cooling machines. The environmental impact in terms of CO2 emissions is investigated. A conclusion drawn from the project is that the use of district heating and cooling of Nya Studenternas IP and the Uppsala University Hospital could be reduced in several ways by integrating the energy systems of the two facilities. For instance, with the support of a seasonal snow storage and cooling machines for cooling, and heat obtained from the cooling machines for heating, the emissions of CO2 could be reduced with 36% based on a Nordic electricity mixture. Out of the suggested integrated energy solutions the most efficient when it comes to reducing CO2 emissions is cooling and heating through cooling machines with a capacity of reducing the CO2 emissions of 20.6 %.
