Quantification of Building Thermal Resilience Against Heatwaves
Defining and quantifying building thermal resilience is important given that this helps determine the capability of a building system to tolerate disturbances from exposure to extreme heat events, and from which to compare different retrofit strategies to enhance the robustness of a building system to such events, and as well, to estimate the rapidity of recovery from heat events that increase the likelihood of having a comfortable indoor environment. In this study, building thermal resilience to summertime heatwaves is defined based on the concept of a resilience trapezoid. The Thermal Resilience Index (TRI) and its labelling class (Class F to Class A+) are proposed as a means to quantify the resilience level in respect to the relative improvement from original and adequate indoor comfort conditions. The distribution of resilience at the Zone level is analysed and is a focus of the research on building thermal resilience. This framework is demonstrated with an 5-storey long-term care building before and after retrofits, the retrofits used to render the building more resilient to heat events. Using four different passive strategies to mitigate the effects of extreme heat events, the highest resilience level that can be reached is Class B, which provides an improvement of 50%-70% in the degree of resilience. From the work completed in this study it is shown that the TRI index is useful in assigning the overall and spatial resilience of a building.
