In an era of expanding climatic concerns, cities are facing pressures to plan and implement ways to alleviate the consequences of heat exposure. Rapidly increasing temperatures and heat waves are becoming more prevalent worldwide, putting strain on city inhabitants and resources. In the US alone, the frequency of heat waves has increased from an average of two heat waves per year during the 1960s to six per year during the 2010s and 2020s. In more vulnerable contexts, rapid urbanization will amplify the projected air temperature change, resulting in increasingly warming conditions in dense urban settings. At the core of this issue is an alteration of microclimate conditions, an increased use of cooling energy in buildings and in its most extreme form, a threat to occupant health and mortality. The climate imperative hence has drawn focus to the built environment, as it is particularly susceptible to those changes and in turn has a strong impact on urban heat flows in both indoor and outdoor environments. The challenge then becomes to conceptualize new approaches to measure the effect of heightening heat levels and formulate integrated solutions that are sensitive to the scales of both indoor and outdoor environments.
This class explores the linkages (under the lens of measurements and solutions) between scales, from the component, to the building and the urban level. Expanding the system boundary is key to arriving at more holistic outcomes that are rooted in finding long-term resilient strategies. The contents presented in this course will provide students the necessary tools to tackle such questions as:
- What data can be made available to help building practitioners and urban planners develop more effective solutions?
- How do we define thermal comfort and how does that inform the strategies we formulate to reach thermally resilient design?
- In light of the expectation of space cooling demand to triple by 2050, how can we design buildings and urban environments that lessen the reliability on active cooling modes?.
- How do we build climate-resilient cities with minimal material impact? What are the compromises between urbanization and low-energy urban cooling strategies?
Course Format:
Introduction to the indoor and outdoor implications of heat in the built environment will be covered. Students develop the first intuition for the multi-faceted aspects of the problem and critically analyze heat assessment methods and strategies for intervention. During morning sessions, a series of lectures and concept-based short discussions strengthen the engagement with each of the four main topics presented in a 4-step framework (Designing across scales, Leveraging data, Measuring impact and Framing action). In the afternoon, a combination of hands-on group exercises and discussions present the technical challenges of assessing the impact of heat at each scale and the formulation of design solutions.
