For various planning and policy issues the estimation of future development of heating and cooling demand is of great importance. In this paper we provide exemplary model results for the development of heating and cooling demand for 31 European countries which have been developed in the project Mapping and analyses for the current and future (2020 - 2030) heating/cooling fuel development. (See Fleiter, T.; Steinbach, J.; Ragwitz et.al.). Within this article we focus on the analysis of relevafornt indicators such as the development of total heat demand, specific heat demand per m2, shares of the end use categories space heating, water heating and space cooling as well as renewable shares and CO2 emissions. Additionally to the descriptive part of this study in which we want to provide a snapshot on heating and cooling demand in the European Heating and cooling demand we also discuss potentials for additional CO2 reduction potentials of the residential building stock.
