While these problems are present at building level, they are multiplied at district level, where there are complex interactions to analyse, simulate and improve. OptEEmAL proposes a solution as a decision-support tool for the design of energy retrofitting projects at district level. Based on specific input data (IFC(s), CityGML, etc.), the platform will automatically simulate the baseline scenario and launch an optimisation process where a series of Energy Conservation Measures (ECMs) will be applied to this scenario. Its performance will be evaluated through a holistic set of indicators to obtain the best combination of ECMs that complies with user's objectives. A great reduction in time and higher accuracy in the models are experienced, since they are automatically created and checked. A subjective problem is transformed into a mathematical problem; it simplifies it and ensures a more robust decision-making. This paper will present a case where the platform has been tested.http://creativecommons.org/licenses/by/4.0/Central Europe towards Sustainable Building 2019García-Fuentes_et_al_CESB_2019.pdfChania [Greece]Library of TUC2020-05-29application/pdf543.6 kBfree García Fuentes, Miguel Hernández Gema Serna Víctor Martín Susana Álvarez Sonia Lilis Georgios-Nektarios Λιλης Γεωργιος-Νεκταριος Giannakis Georgios Γιαννακης Γεωργιος Katsigarakis Kyriakos Κατσιγαρακης Κυριακος Mabe Lara Oregi Xabat Manjarrés Diana Ridouane Hassan El De Tommasi Luciano IOP Publishing OptEEmAL Decision making Decision-support tool Energy Conservation Measures
