We asked an international panel of our experts to weigh in on several topics focused on the impact of COVID-19 on urban planning and design around the globe. This is the first of a four-part series featuring their answers.

Today¡¯s question: Thinking about non-healthcare interventions like ¡°mitigation,¡± ¡°suppression,¡± and ¡°quarantine,¡± what role do planning and design have in helping to prevent pandemics in the future?

Design has an important social role. It has the role of interpreting societal needs by translating them in an empathetic and innovative way.

Thanks to the ability to grasp the variety of signals and the changing needs that come from society, design has been a key element in the process of modernization of society itself. This way, design has always distinguished itself as a creative approach to complex problem-solving.

The total closure of nonessential activities and the rules of social distancing that are precluding us from using urban and public places that characterize the spirit of the city itself (offices, bars, restaurants, squares, parks, museums), do not represent a solution nor a direction that will define our way of living in cities. Those are temporary tools based on hygienic and sanitary principles responding to a state of emergency, they do not include an interpretation of needs and therefore do not enclose the planning process in themselves.

Creativity¡ªcapable of interpreting changes in society¡ªand adaptability will be the mitigation that design and planning can support.

Possible actions are:

• Maximise digital interfaces in order to make goods and food-distribution services accessible to everyone by structuring an articulated and powerful system, capable of replacing traditional methods of services distribution when needed.
• Create temporary-use scenarios, such as review of the layout of bars and restaurants, as well as public and private offices in order to make them suitable for gradual opening and make them flexible in use and linked by digital infrastructures.
• The use of open space could be a possible scenario for some activities normally developed and settled indoors.

Among many other aspects, planning is also a humanistic discipline. It is important to keep in mind that the problems we face in this pandemic situation require empathy, recognition of others¡¯ difficulties, and a focus on interpreting needs.

In Italy, where many businesses and spaces still have a rather traditional footprint, we had to quickly reconfigure many sectors. For instance, teaching had to redefine the relationship between students and teachers through online learning. Industrial production, in many cases, was converted in order to respond to the request for sanitary supplies. Extemporaneous hospitals have popped up in all of the major cities in the country.

This whole experience was a challenging training ground for conversion, adaptation and flexibility. Design must continue to focus on innovation in order to counteract any potential regression brought by the pandemic.

Planning and design set the tone for how people interact with one another, and environment strongly influences human behaviour. So, we as designers have a significant responsibility to play in a post-pandemic world. Our designs can ¡°force¡± (through physical separation such as walls or mechanical systems) or ¡°suggest¡± (through the use of tools like scale and pattern) that different behaviors take place within specific spaces¡ªwhether that equates to greater separation between people in areas of higher risk, better physical and mental support for our healthcare workers, or anything in between.

Additionally, many practical design measures may be implemented to mitigate the spread of disease in the future. Perhaps we will see:

• Blurred lines between sectors, so that nonmedical settings such as hotels, convention centres, and community spaces are designed up front to be more easily transformed into emergency medical facilities on demand.
• Separated HVAC systems for patients and visitors in hospital settings.
• Increased use of limited to nonabsorbent materials in our buildings (acoustic panel ceilings, carpet, fabrics, etc.).
• Increased flexibility and agility inherent in design and layout of spaces.
• Walls and surfaces that are easily cleaned¡ªwhether that means more streamlined shapes that avoid ledges and hard-to-reach corners, or materials that can withstand being wiped down with disinfecting chemicals.
• More widely available public amenities to support hygiene¡ªpublic handwash stations, community showers, higher standards for restroom design and maintenance.
• New space-allocation standards that allow for social distancing in place¡ªfor example, perhaps office planning will standardise at 6 feet minimum between people, seat spacing on airplanes may expand, waiting areas in hotels, airports, and doctor offices may be larger to allow for greater distance between seats.
• Further developments in touchless technology like elevators and mass transit options.
• Overall renewed emphasis on social justice and design equity for all.
• Companies with large centralised campuses may decentralise to distribute their workforce and mitigate risk. Overall space demands may change if employees now expect to be able to work from home.

As urban planners and designers, we cannot grasp the full parameters of the next epidemics. However, based on historical experience,?the evolution of public health and its impact is?influenced by the existing economic structure of the city and the strategies and responses utilised by regional institutions. This current crisis may be an important opportunity to promote the transformation of traditional planning approaches.

During this current pandemic, epidemiologists, biomathematicians, transport departments, public health departments, and private organisations have used ¡°space maps¡± to publish the status and predictions of the epidemic situation and distribution. If we look at this from a different perspective, urban planners also can join to fight against disease if we can enhance the interpretation of the spatial information flow model behind the big data driving the space maps. It might be possible to propose a kernel algorithm¡ªlike the weather forecast model predicting the trajectory of a typhoon.

In every major epidemic, the site selection for large-scale, response-focused health facilities always attracts people¡¯s attention. For example, the Beijing Xiaotangshan Hospital during the SARS period and the Wuhan Vulcan Mountain Hospital during this COVID-19 pandemic, have been able to help manage and reverse the situation in these times of crisis. However, the fate of these temporary hospitals after the pandemic have become a problem. Xiaotangshan was abandoned immediately after the SARS epidemic because it was no longer needed, and because of its location outside the city proper. Until recently, it was called ¡°Silent Hill.¡± However, it was put back into service to treat COVID-19 patients in March 2020.

Urban planners may be able to help with location selection for temporary epidemic treatment facilities in support of long-term viability, strengthen transport and urban infrastructure access, as well as prescribe action plans (concentration, evacuation, rehabilitation) to avoid being forced to reactivate and prepare a facility and site only after an epidemic occurs.

Arguably, public health can no longer afford being a cookie-cutter factor in infrastructure planning and construction. It is necessary to examine the current needs and balance these against future population dynamic needs, resource allocation, and actively promote collaboration between public health and urban spatial planning through a resilience perspective.

Tom Young¡ªMontreal, Quebec, Canada

Pandemic is still an acute and exceptional circumstance, and to design everything around pandemic considerations would be counterproductive to well-functioning and enjoyable cities the rest of the time. As scary and all-encompassing as this crisis has been, I think we must assume that there will be public health solutions to manage or eliminate the virus, that will make this a shorter-term situation.

Planning and design response should continue to focus on building urban places and systems that do a really good job of facilitating our everyday economic and social needs, layering in pandemic considerations where they align. I think pandemic considerations should become a lens we look at planning and design through but not the primary driver.

Keith Mitchell,?Scott Witchalls¡ªReading, United Kingdom

Living standards are becoming increasingly important in design considerations. We have seen a reemergence of standards such as the Design for Life Standard, Lifetime Homes, and the WELL Standard, which are now being reapplied to development.

None of these address issues relating to the pandemic directly but do offer opportunities to consider better living and home working, such as air-quality standards, better lighting, and access to communication infrastructure.

It would be more pertinent now to take the learning related to implementing an emergency response and apply it to climate change response, a global emergency that currently does not have the same radical interventions applied to it.

We know for certain that this virus (and similar pandemics) are spread primarily through close physical contact or surface contamination in public-use spaces (e.g., public transport, elevators, door handles). Since it is proven that reducing such contact reduces the spread of the disease, we need to design places that can be set up to operate and function in a different way when required. This means we need to design in resilience plans that enable communities to be self-sustaining when necessary, and able to self-isolate without significantly affecting economic and social well-being.

Examples could include:

• Flexible building use zones with ¡°plug-and-play¡± building design (office to lab space, car park to food production, warehouse to field hospital, etc.)
• Clean food production areas and automated home food-delivery systems
• Digital systems and communication networks that can process community scale requirements into physical delivery and provide social interaction platforms for all to use
• Economies that can be successful by minimizing the need to travel (Walkable Cities Concept)
