The practice of architecture today is essentially responsible for providing ethical solutions for habitation and settlement issues, while ensuring that the impact of its design decisions will not compromise the welfare of future generations (Collier, 2006). Although much is discussed in the literature about sustainable projects or green-building rating tools, the way architecture is being practice today still has enormous environmental, societal and economic costs.
So, the biggest barrier to achieving a sustainable future through architecture is not a lack of knowledge about sustainable architecture, but the gap between environmental knowledge vs environmental behavior (Kollmuss and Agyeman, 2002).
Therefore, behavior change strategies are an important element that should be included in holistic methodologies to design, evaluate and practice architecture. This can influence architects’ and clients’ design choices towards pro-environmental behavior.
Responding to this challenge, this study introduces the concept of Responsible Architecture (RA). RA is presented as a design paradigm that uses participatory sustainable building practices to promote long-term sustainable behavior as a goal. This will be achieved by developing a framework for planning and building projects that uses design principles and techniques in four main areas: environment, society, economy and behavior change strategies.
