The field of architectural environment refers to the technical area that deals with the physical performance of buildings, which must be considered throughout the process of producing architectural structures. The physical performance of a building depends on the spatial elements, thermal/light/sound environment factors, indoor air quality factors, and the architect's knowledge and experience related to the integration of these elements. This course will introduce the basic theories, design, and evaluation techniques required in future architectural practice, focusing on thermal environmental factors. It prepares students to create comfortable indoor environments, as well as to design environmentally friendly and energy-efficient buildings.
