摘要：The concept of sustainable architecture in the developing world needs to be holistically rethought. In the context of constraint based design, a sustainable movement should adhere to contextual and adaptive systems that are characterized by appropriate, available, and climactic specificity. However, these conditions often evade international development projects in the tourism industry, in which there are examples of "greenwashing" and failure to have a sustainable local impact. Such problems require us to rethink the meaning of "sustainability," expose an inherent ambiguity in the overuse of the term, and suggest the need for better metrics. Architectural projects have the potential to address sustainability in the context of development by employing innovative low-tech solutions that can have reverberant and systemic change on economic, social, and environmental levels. As an example, a naturally ventilated hospital in Rwanda shows how an architectural project can impact public health by mitigating the transmission of airborne disease, reduce energy consumption, energize a local economy, and build a local skilled labor force. In order for this design revolution to truly impact development, it needs to embrace an expanded definition of sustainable design practices that includes a more multifaceted approach to the built environment
