Buildings can produce less greenhouse gas emissions while being more energy efficient, comfortable, healthy, and economical through the proper application of sustainable design, construction and operation principles. In this course, students are introduced to environmental issues associated with buildings as well as concepts of performance indicators. Also, students are exposed to the fundamental knowledge of modeling methods and simulation tools used in performance-based building design, and operation. This sets the ground for an in-depth discussion of performance prediction for energy demand and the use of building simulations in life cycle analysis for the selection of energy-efficient building components and systems.
