This workshop emphasizes the man-made character of microclimates, and as such, expands existing approaches from applied climatology and building science. As artifacts, microclimates are part of local material cultures with various ecological, social and cultural implications. The workshop highlights the critical role of architects in the design and construction of microclimates, and it provides various insights into how to investigate microclimates by means of architectural-ethnographic approaches. After an overall introduction into the history and theory of microclimate ethnography, the students will conduct an on-site exercise (a microclimatic walk), followed by a quick design project (highlighting the diversity of microclimates).
