Sascha Roesler is an architect and theorist, working at the intersection of architecture, ethnography and science and technology studies. Since 2016, he is the Swiss National Science Foundation Professor of Architecture and Theory at the Academy of Architecture in Mendrisio, Switzerland (Università della Svizzera Italiana). Roesler was mandated by SNSF to set up a new special research field on “passive climate control and the city;” within that framework, he leads a group of doctoral and postdoctoral researchers. With the underlying rationale of the city as political ecology, the project combines microscale investigations of local thermal practices, the use of energy commons and the political regulations of climate control. From 2013 to 2015 he has been a senior researcher and academic coordinator at the Future Cities Laboratory of ETH in Singapore. Roesler, who holds a doctorate from the ETH Zurich, has published widely on issues of global architecture, sustainability and relocation. His publications comprise the first comprehensive global history of ethnographic research conducted by modern architects: “Weltkonstruktion” (Berlin 2013), and “Habitat Marocain Documents” (Zurich 2015), a volume on the transformation of a colonial settlement in Casablanca. The latter was awarded the DAM architectural book award in 2016 as one of the year’s ten outstanding architectural publications. Most recently, Roesler co-edited the anthology “The Urban Microclimate as Artifact” (Basel 2018). This publication expands existing approaches from applied climatology and building science by emphasizing the man-made character of urban microclimates. As artifacts, microclimates are part of local material cultures with various ecological, social, and political implications for contemporary cities. Roesler is one of the laureates of the Swiss Art Award for Architecture.
