The need to reduce energy consumption and improve the comfort of inhabitants is compounded by the need to preserve an environment of heritage value. The selection of rehabilitation strategies at urban scale offers significant benefits, but makes the process long and costly. Therefore, methods or tools are necessary to establish a rapid assessment that facilitates strategic decision making and a deeper analysis of a reduced number of alternatives.This paper describes a method that supports decision making regarding the suitability of Energy Conservation Measures (ECMs) in historic districts at early stages. The method considers the improvement of the energy performance of buildings as a positive impact, balanced with the negative impacts that the implementation of ECMs could produce. A CityGML-based urban model allows the automation of a multi-scale assessment for different ECMs and provides possible global energy demand reductions. This method, combined with an economic evaluation, can be used by decision makers for large-scale energy retrofitting. The applicability of the method is demonstrated through implementation in the historic city of Santiago de Compostela.12960747enginfo:eu-repo/semantics/openAccessjournal article10.1016/j.enbuild.2017.12.061Urban conservationHeritage impact assessmentCityGMLEnergy conservationMultiscalarityUrban conservationHeritage impact assessmentCityGMLEnergy conservationMultiscalarityCivil and Structural EngineeringBuilding and ConstructionMechanical EngineeringElectrical and Electronic EngineeringSDG 11 - Sustainable Cities and CommunitiesSDG 12 - Responsible Consumption and ProductionProject IDinfo:eu-repo/grantAgreement/EC/FP7/314678/EU/ENERGY EFFICIENCY FOR EU HISTORIC DISTRICTS SUSTAINABILITY/EFFESUSinfo:eu-repo/grantAgreement/EC/FP7/314678/EU/ENERGY EFFICIENCY FOR EU HISTORIC DISTRICTS SUSTAINABILITY/EFFESUSFunding InfoThe authors gratefully acknowledge the European Commission for providing financial support during the_x000D_ research under the EFFESUS project (Grant Agreement Number 314678).The authors gratefully acknowledge the European Commission for providing financial support during the_x000D_ research under the EFFESUS project (Grant Agreement Number 314678).http://www.scopus.com/inward/record.url?scp=85041439597&partnerID=8YFLogxK
