Retrofitting Concrete Utopias: Climate Change Adaptation for Mid-Century Housing Stock

Toronto is the site of nearly two thousand 1960s concrete residential tower blocks in various states of maintenance, in various locations, more or less peripheral to the major public transit corridors, housing in many cases vulnerable populations on the peripheries of the economic core of the city. Overcrowding of apartments, lack of affordability, inadequate maintenance of basic amenities has been identified as significant problems in academic and social agency reports. This paper is concerned with extreme heat events related to climate change and mortality especially for vulnerable population in these legacy towers. My contribution to this discussion takes as its framework of analysis an understanding that social processes are sociopolitical negotiations in uneven relative power relationships. They are political and environmental. This project is driven by concerns for the experiences of human well-being in the face of the global climate emergency, efforts at reducing operational carbon emissions, and energy consumption, for cooling especially. Comparable towers in France and Switzerland, as well as low rises there and in Germany, are examined, buildings that have undergone significant retrofitting to address these issues. The towers and site analyses are approached within their specific locations, the natural environment and the social infrastructure within which they stand. Practical learnings from European cases and current practices in Toronto lead to practical policy recommendations that aim to bolster institutional and financial capacity in the Toronto situation to address the dual crises of affordable housing and climate change mitigation.
