Professionals’ knowledge and use of environmental assessment in an architectural competition

ABSTRACT In early design phases, architects, landscape architects and urban planners are key actors whose decisions determine the environmental impact of planning and building projects. Environmental and sustainability assessment tools for buildings and neighbourhoods have been developed to promote sustainable building, but their usage has not been thoroughly evaluated. This study investigated self-reported knowledge and usage of such tools among competitors and jury group from 10 European countries involved in the international architectural competition ‘A New City Centre for Kiruna’ in Sweden. The questionnaire revealed that 13% used environmental assessment tools or management systems in the competition, although 47% had used them previously. Tool users reported greater knowledge of how to handle environmental impacts than non-users. However, the self-rated experience of handling various environmental impacts, in the competition and in general, was low for both groups. Nevertheless, the self-rated importance of environmental impacts was high among all participants. Based on this study, it is concluded that environmental assessment tools, issues and goals can be better integrated into the processes of early design in planning and building projects, and in architectural competitions. Furthermore, to limit environmental impacts in building and planning projects, professionals need to be educated about environmental strategies and solutions.
