This paper presents the key findings of a master's dissertation developed as part of the Environment and Energy Studies Programme of the Architectural Association Graduate School - AA, London, in 2003/2004. The study investigates the applicability of double-skin façades on high-rise office buildings in the city of São Paulo, Brazil. As part of the investigation, the origins and characteristics of the systems are studied, identifying suggested reasons for the use of such façades in high-rise offices. Conceptual models were created to qualitatively compare and evaluate the performance of different double-skin typologies. A comparative analysis was undertaken taking the climatic conditions of São Paulo into account. The application of double-skin façades was investigated with dynamic thermal simulation, using TAS (EDSL 2003) to assess thermal performance, and using ECOTECT (Square One 2004) and RADIANCE for daylighting studies. The results provide an overview of environmental considerations underlying the design and possible application of double-skin façades in São Paulo.Downloads
