Energy and comfort in buildings

Summary

The course presents the fundamentals of energy demand in buildings while emphasizing the need for the comfort and well-being of occupants. In addition, prioritizations and trade-offs between energy and comfort are discussed.

Content

Keywords

Energy demand; human comfort; indoor environmental quality; building envelope.
