RT Conference Proceedings T1 HOW ARE HEAT WAVES PUTTING AT RISK HISTORIC URBAN AREAS? FIRST STEPS FOR DEVELOPING RISK ASSESSMENT METHODOLOGIES A1 Quesada-Ganuza, Laura A1 Garmendia, Leire A1 Rojí, Eduardo A1 Álvarez, Irantzu A1 Briz, Estibaliz A1 Gandini, Alessandra A2 Blanco, Haydee A2 Boffill, Yosbel A2 Lombillo, Ignacio AB It is worldwide accepted that climate change is affecting cities and that the conservation of the cultural heritage contributes to sustainable development. However, despite the high level of interest and research in climate-change risks, a holistic understanding of the risk that heat waves and heat urban island phenomena present to urban cultural heritage is noticeably absent from literature. Aside from understanding the impacts that heritage faces with climate change, the consideration of loss of heritage and cultural values and assets due to extreme heat waves will promote the resilience and sustainability of both social and built environmental systems. The aim of this paper is double, first to identify key performance indicators for risk assessment  methodologies that address both the elements of historic urban areas as a system and the potential impact of prolonged heat waves. Second, this study aims at developing a categorization for both buildings and urban spaces within historic urban areas regarding their vulnerability to heat waves, which will be the basis for further risk assessment. For this twofold purpose, the interaction between urban spaces, heat waves, and the urban heat island is addressed as well as the vulnerability and behaviour of traditional materials and building typologies. To define the elements that conform historic urban areas, the system is addressed from two perspectives, as an urban system, and as a historic area. At the same time, for a holistic approach, every element of the system is assessed, distinguishing between socio-economic, cultural, governance (services and resources) and physical (gathering tangible characteristics of all infrastructures, elements and buildings) aspects. The indicators and categorization are, therefor, essential for the evaluation of the impacts of heat waves and the urban heat island on the elements that conform the system of the historic urban area.
