In an increasingly hotter world, what policies, designs, technologies & behaviours can provide thermal adequacy for coolth?
Buildings and cities have become highly dependent on air-conditioning and mechanical ventilation. Without significant intervention demand for air-conditioning (AC) is projected to rise by 700% by 2050. The implications of an unsustainable increase in cooling demand are being recognised in many countries around the world.
Recent discussions about ‘build back better’ after the Covid-19 pandemic afford an opportunity to reconsider many contemporary practices in the built environment: health and wellbeing, thermal comfort and the agency of building occupants, adaptation to climate change, energy use and environmental impacts, economics and equity, social expectations and demographics, design and innovation, thermal characteristics of buildings and cities. In addition, many countries have stipulated that new buildings must be carbon neutral. Climate change will create an increasingly warmer world – impacting on summer overheating in buildings. This is an urgent concern for both mitigation and adaptation: how can thermal comfort be provided during hotter summers without the GHG emissions? ‘Conventional’ air conditioning will soon be technologically redundant. Can our cities and buildings be designed to have little or no mechanical intervention?

This special issue explores alternative approaches to providing thermal comfort and ventilation in different climatic zones across the world at the scales of building, neighbourhood and city. It considers the implications of these alternatives across a range of issues: health, wellbeing, air quality and heat stress; technical / design solutions; social expectations and practices; climate change; policy and regulation; supply chain and procurement; education and training. It includes a range of disciplines: geography, sociology, anthropology, behavioural sciences, architecture, engineering, public health, economics, energy and environmental assessment.
Collectively the papers in this special issue describe a range of viable approaches to ‘alternatives to air-conditioning’ and contribute to an understanding of the opportunities for better informed practice and policy. These alternatives embrace much more than a technological issue: they require holistic design thinking, and include social aspects (expectations, behaviours, practices).
However, the special issue reveals a number of significant gaps which are discussed in the editorial. New pathways to successfully implement alternatives to air conditioning need to be led by policy and regulation, as well as new business models in creating market demand. In this transition to a low carbon future the questions are not just ‘What?’ and ‘Why?’, but primarily ‘How?’. A critical issue will be redefining professional practices, design decision processes, performance standards and capabilities for designing for performance and optimisation processes.

The Challenges of Evidence-Based Design
While some progress has been made, particularly in areas like healing architecture where the impact of design on human well-being is more directly observable, much work remains to be done to extend evidence-based design to broader fields of architecture, urban planning and design. Meta Berghauser Pont (Chalmers University of Technology) explains the challenges and pathways needed for a shift toward evidence-based design in urban planning and urban design.
Rethinking Construction Product Regulations
Mustafa Selçuk Çıdık (University College London) considers the crucial role that research and higher education need to play in generating evidence and knowledge to shape the complex landscape of construction product regulations, particularly in relation to innovation, safety and performance. Independent, robust research and clear guidance are needed to ensure public safety, technological progress and sustainability. In addition, higher education must prepare future professionals to work within, and critically challenge, these regulatory frameworks.
