Barriers to and facilitators of climate change action in architecture practice

There is urgent need for the transformation of built environments to tackle climate change. The reduction of greenhouse gas emissions to achieve the Paris Agreement goal of limiting warming to well below 2 °C is of paramount importance, as is planning for future climate change risks. Architects, as designers of the built environment hold an important role in advocating and enabling the necessary mitigation and adaptation actions required in the design and construction of new buildings, and the reuse of existing built fabric – to reduced embodied carbon and achieve operational energy efficiency. Despite the importance, most built environments do not yet adequately address climate change. Limited research has examined the barriers that architectural professionals encounter when integrating climate change action in their projects during their role designing built environments. This is the gap that this research addresses. Interviews with twenty-two Australian architectural practitioners were undertaken, to investigate their experience of barriers to and facilitators of climate change action in their professional practice. Four key themes were found: 1) actors, 2) processes and structures, 3) information and knowledge, and 4) the role of government. Barriers and facilitators were found to be embedded in architects' perception of their role, the processes and practices they undertake, and their relationship with other stakeholders. The facilitators identified can assist drive better outcomes for future design and construction of buildings. Recommendations identified include: 1) build architects' confidence and capability to be advocates; 2) develop of architects' climate change knowledge and competence; 3) transform design processes to be more circular, interdisciplinary and long term focused, and 4) reform current built environment policy to adequately consider climate change.
