1. 1 Giovanni Langella PhD at ETH Zurich/ EMPA Presentation Urban Physics spring school 2016

2. 2 Background BSc – MSc Energy Engineering Aerospace and Wind Energy Working Experience o Research in fluid dynamics o Energy saving and energy management March 2016 – today PhD in urban microclimate

3. 3 Research topic “Heat removal potential in urban configurations” Goal:  Enhance the understanding of flows in urban configurations due to main wind, turbulent coherent structures and buoyancy, and their influence on heat removal  Propose urban heat island mitigation measures and quantifying their heat removal potential (e.g. green roofs, reflective paints) Impact:  The understanding of urban flows will lead to an energy-efficient management of new building installations taking into account the UHI effect, and contributing to the reduction of heat waves and peaks in pollutant concentration

4. 4 Methodology Small scales Large Scales  Higher spatial resolution  Resolving turbulent coherent structures  Only point measurement for air temperature and scalar concentrations  Simultaneous measurement of flow and temperature or concentration field  Pollutant dispersion from some buildings into the atmosphere  Measurement of thermal plumes over the urban area
