In this paper we present a new method for simulating and mapping energy demands for European museums for recent past (RP), near future 2020-2050 (NF) and far future 2070-2100 (FF). It is new combination of three recent developments: Firstly, the simulation and mapping of building performance indicators based on European weather stations. Secondly, a multi zone energy model, representing a wide range of museums. The latter consists of 16 different museum zone types equal to all combinations of 4 levels of building construction and 4 levels of climate control. Thirdly, the availability of hourly based, EU wide, external future A1B climate files from the EU FP7 Climate for Culture project. We used 7 performance indicators: (1) mean indoor temperature; (2) mean indoor relative humidity; (3) mean heating demand; (4) mean cooling demand; (5) mean humidification demand; (6) mean dehumidification dem nd; (7) total energy demand, to produce EU maps for 16 museum types and five 30 year time periods: RP, NF, FF, NF-RP and FF-RP. This gives in total 560 maps. The most important mapping results are included and discussed in this paper.
