This course aims to introduce students of architecture with the basics of passive solar design, an approach that support the minimization of energy consumption in buildings  by eliminating the need for active mechanical systems (and associated fossil fuel-based energy consumption) where optimum occupant comfort is targeted at all times. Additionaly, the course intends to raise an awareness towards environmental and sustainability issues where the importance of building shape and orientation, use of appropriate  materials and structural systems, various passive solar building concepts and design principles in vernacular and contemporary examples  are discussed in detail.
