Professional’s insights into planning and designing for extreme heat

Our urban environments are getting hotter, yet urban design and planning solutions which can mitigate heat are rarely used. There is a need for further education and strategic planning policy positions to support heat mitigation policy and practice in the built environment.

Target audience

Built environment policy makers, planners, urban designers, and resilience professionals

The problem

Climate-responsive design is well understood at the building scale, but less so at the scale of the public realm. Urban design and planning can both assist in reducing heat health risks in the built environment, however such climate-responsive solutions are rarely implemented.

What we did and why

We surveyed and interviewed over 40 built environment professionals working in South East Queensland, asking them about how they consider extreme heat in their practice. In doing so, we explore the resources and policy built environment professionals in South East Queensland require to further the uptake and implementation of evidenced based responses to extreme heat hazards (urban heat and heatwave) in this growing region.

Our study’s contribution

We found that:

• Design-centric professionals (e.g. architects and urban designers), compared to planners, reported greater awareness of heat mitigation practices
• The Queensland Planning Framework presents challenges to heat mitigation, including a lack of strategic policy position on heat and limitations of statutory instruments.
• ‘Vegetation’ was reported as the most used heat mitigation response, while ‘water’ was used the least.

Impacts for city policy and practice

• Lower awareness of extreme heat among planners may result in poor policy and urban development outcomes relating to heat and climate-responsive design.
• Built environment professionals may require more support, via tertiary education and professional development, to embed climate-responsive design for the public realm into policy and practice.
• Extreme heat mitigation needs to be included in strategic planning policy, supporting mitigation responses at all scales of planning and design.

A psychology and power intervention to help decision-makers prioritise health in ­­­urban development

Evidence overwhelmingly suggests that the built environment has an impact on people’s health, particularly in terms of noncommunicable diseases such as asthma, diabetes and poor mental health. However, health is rarely prioritised in urban planning decisions at present, and earlier work by this research group has shown that senior decision-makers feel they lack the power to influence planning and policy decisions in order to improve the situation. This intervention area adds to the wider research programme, which is focused primarily on the delivery of quantifiable socio-environmental and health economics valuations. People make decisions not just based on economic valuation, so an understanding of why people make decisions and how those decisions can change is essential. This paper describes the methodology that will be used to develop this intervention. Findings will be published later.

Health impact assessments for healthier urban planning projects

Health impact assessments are a key tool to bridge the worlds of planning and health, but there’s a risk they become a ‘tick box’ exercise with little real-world benefit. Learning from recent practice in English local authorities can help maximise their effectiveness in producing healthier developments.
