This lecture covers topics such as color perception, superposition of waves, undulatory theory, building physics, colorimetry, light propagation, geometric acoustics, sound propagation, solar energy, and radiation. It also discusses the integration of photovoltaic systems in buildings, including full PV facades, solar roofs, and large-scale solar facades. The instructor presents case studies of innovative solar integration projects, such as the world's largest solar facade at the Copenhagen International School. Additionally, the lecture explores radiometric quantities, reflection, transmission, and the measurement of luminous sensation and radiation using photometric devices.
