Design Studio 3 focuses on the integration of environmental systems and architecture, where the design of a building is also the design of how it provides its occupants levels of comfort. The program for the semester-long investigation is Housing; this studio will use housing typologies as the lens for understanding issues of sustainable living systems. How can architecture itself be used to provide positive living environments while reducing energy consumption? This question will be investigated in the studio while engaging sustainable design strategies for Housing. As such, the studio will investigate housing design issues of standardized units, variation, and aggregation and their relationship to sustainable design issues. The studio is taught in conjunction with PUAD 3000 Environmental Technology: Architecture and Energy, where students will learn quantitative approaches for analyzing their design projects.
