LEED: Toolkit for a Healthy and Resilient Post-COVID Built Environment
At SWA, we have used LEED across a wide range of projects and contexts. We have seen firsthand its strength as an adaptable toolkit for guiding high performance building design, construction, and operation. The intent of each LEED credit category takes on a particular meaning, both locally and globally, in response to the emergence of such factors as global climate change and its associated consequences—including pandemics. In the post-COVID context, these intents will take on new meaning and new urgency.
The overall goal of the LEED rating system is to reduce the negative impacts of the built environment on environmental and human health. Ideally, this focus contributes to our general, overall resilience to public health crises such as the COVID-19 pandemic by reducing and mitigating various factors that make us more vulnerable to diseases. For example, we know that long-term exposure to air pollution and poor air quality dramatically increases the chances of dying from COVID-19 and that most of the same pre-existing conditions that increase the risk of death for COVID-19 are the same diseases exacerbated by exposure to air pollution. Anything we can do to improve air quality will also improve our resilience to disease. Most significantly, we need to move away from fossil fuel-based energy and toward clean, renewable energy—and a large portion of LEED is focused on doing just that.
As researchers have noted, many of the root causes behind climate change also contribute to a greater risk of pandemics. An example is deforestation and associated habitat loss, which forces wildlife to migrate, bringing novel viruses into closer contact with livestock and humans, and increasing the odds of disease transmission. On top of that, by altering temperature and rainfall patterns, climate change has created conditions that are more conducive to the spread of disease in general. So, the strategies we need to enact now to address the climate crisis—many of which are addressed in LEED credits—can also mitigate the occurrence, scale, and impacts of future disease outbreaks.
