"Hitze" [heat] as a property of bodies, spaces and regions has shaped and continues to shape our thinking about architecture and cities. The lecture series, part of IKA’s 2019/2020 special programme Hitze Takes Command, examines the spatial culture of temperature, and its broader social and political implications, through the eyes of a number of contemporary thinkers. The historians, artists, scientists and architects assembled in this lecture series will explore the topic of "Hitze" in dimensions ranging from the soup pot to the troposphere.
 
Who can think of the future today without consideration of "Hitze"? Every exceptionally warm day is imagined as portending future disaster, while a sudden cold day provides hope that the ravages of climate change might be mitigated. Our experience of "Hitze" is overburdened with dread and yet, "Hitze" is also a form of pleasure – integral to sensations of taste, comfort and sexuality. We hope to discover and understand more about the realm of "Hitze" in explorations of fields that will shape the future of architecture and urbanism.

Urban planning and architecture were traditionally based on climate, comfort and health, as can be seen in the treaties of Vitruvius or Alberti, where exposure to wind and sun, temperature variations and humidity determined the shapes of cities and buildings. These root causes of urban planning were ignored in the second half of the 20th century due to the enormous use of fossil fuels by pumps, motors, refrigerators, heating and air conditioning systems that are now causing particulate air pollution, the greenhouse effect, urban heat Island effect and global warming. Faced with the climate challenge of the 21st century, we propose to rebuild architecture and the city on their intrinsic climatic qualities, where the convective, conductive, emissive or effusive replace the symbolic, analogical or metaphorical. The conference will present the recent work of Philippe Rahm architects: on an urban scale with the construction of the Taichung Central Park in Taiwan, or the project for the new Farini district in Milan, Italy; and on an architectural scale, with the new public space of the Maison de la Radio in Paris or the Climatorium in Taichung, the global warming museum.
 
Philippe Rahm is a Swiss architect, principal in the office of “Philippe Rahm architectes”, based in Paris, France. His work, which extends the field of architecture from the physiological to the meteorological, has received an international audience in the context of sustainability. His recent work includes the first prize for the Farini competition in Milan in 2019, the 70 hectares Central Park in Taichung, Taiwan, completed in December 2018, the Agora of the French National Radio in Paris, a 2700 m2 Exhibition architecture for the Luma Foundation in Arles, France. He has held professorships at GSD Harvard University, Columbia and Princeton Universities. His work has been exhibited in 2017 at the Chicago and Seoul Architecture Biennales.

The Role of Clouds and Aerosol Particles in the Current and Warmer Climante

Clouds are not only fascinating to observe for their myriad of shapes, but are also scientifically challenging because their formation requires both knowledge about the large-scale meteorological environment as well as knowledge about the details of cloud droplet and ice crystal formation on the micro-scale.

Aerosol particles scatter and absorb radiation and with that cause a cooling, that partly offsets the warming due to anthropogenic greenhouse gases. Aerosol particles also influence the microphysics of clouds by acting as cloud condensation nuclei and ice nucleating particles. The magnitude and geographical distribution of the cooling caused by aerosol particles themselves and by aerosol-cloud interactions is much more uncertain than the greenhouse gas warming because aerosol particles have localized sources and sinks and only have an atmospheric residence time of days to weeks.

An additional uncertainty related to clouds is that it is not yet clear how clouds change in a warmer climate. In this lecture, I will discuss the role of clouds and aerosols in the current climate and in climate projections.

Ulrike Lohmann is Full Professor for Experimental Atmospheric Physics in the Institute for Atmospheric and Climate Science since October 2004. She was born in 1966 in Berlin (Germany) and studied from 1988 to 1993 Meteorology at the Universities of Mainz and Hamburg. In 1996, she obtained her PhD in climate modelling from the Max Planck Institute for Meteorology. She was a post-doctoral fellow at the Canadian Centre for Climate (1996–97) and Assistant and Associate Professor at Dalhousie University in Halifax (Canada) (1997–2004). Ulrike Lohmann was awarded a Canada Research Chair in 2002, received the AMS Henry G. Houghton Award in 2007, was elected as a fellow of the American Geophysical Union in 2008 and of the German National Academy of Sciences, Leopoldina in 2014. She was a lead author for the Fourth and Fifth Assessment Reports of the Intergovernmental Panel for Climate Change (IPCC). She was the coordinator of the EU FP7 project BACCHUS (2013–2018). At ETH, she was the head of the Institute for Atmospheric and Climate Science from 2006–2014, is a delegate of the ETH president for heading search committees and vice president of the Lecturer's conference. Since 2018 she is a member of the Research Council of the Swiss National Research Council and was awarded a honorary doctorate from Stockholm University. Her research focuses on the role of aerosol particles and clouds in the climate system. She combines laboratory work and field measurements on cloud and aerosol microphysics with their representation in different numerical models.
