Sustainability in Office Architecture: Evolution of Strategies, Policies, and Design Approaches from 1970 to the Present

This paper examines the development of sustainable architectural design strategies in office buildings from 1970 to the present. Drawing on literature, policies, and historical examples, it traces the transformation of sustainability from a loosely defined environmental concern to a structured set of strategies embedded in architectural practice. The research explores how international policy frameworks and environmental crises influenced the architectural profession and shaped design responses. It discusses the emergence of passive and active design methods, the introduction of certification systems, and the shift toward low-carbon, net-zero, and plus-energy approaches. The paper also considers how digital technologies and modern construction methods have supported this evolution. By focusing on office buildings, which are among the most resource-intensive building types, the study highlights how sustainability has been applied across changing economic, social, and technical conditions. It reflects on the effectiveness and limitations of past strategies and argues that a more integrated and collaborative design approach is needed to meet future carbon targets and address wider sustainability challenges in the built environment.
