The relationship between motivations of architectural designers and environmentally sustainable construction design

Research on sustainability in construction design has tended to focus on technological, institutional and economic drivers, but there has been little change in the industry. Social scientific approaches offer insights on the lack of progress. However, few previous studies have investigated psychological factors despite the pivotal role of the individual professional decision-maker. The aim was to understand what personal motivations drive architectural designers to pursue sustainable design in their work and whether non-environmental motivations can drive sustainable outcomes. Twenty-eight architectural designers in 14 small firms in the London area were interviewed. Thematic analysis was conducted, informed by the self-determination theory of motivation. Although extrinsic motivators were noted, autonomous motivations including a moral imperative and personal commitment predominated. Further, the participants demonstrated other self-determined motivations including realization of self-identity, pursuit of quality in design and awareness of their work’s impact on people. These autonomous motivations align closely with sustainability principles including design for durability, high standards and technical expertise. The findings point to the risks of reliance on extrinisic motivators such as regulation, and the opportunities to engage architectural designers more extensively in sustainable design by linking sustainability to autonomous motivations.
