Building Design and Energy Efficiency

The video discusses the significant energy consumption of buildings and the role of energy-efficient windows in reducing this usage. It highlights the benefits of low-emissivity coatings in windows but also addresses potential health concerns due to reduced exposure to certain light wavelengths. The video explores the impact of these windows on circadian rhythms and related health issues like myopia. It also discusses the health benefits of infrared light, including its role in reducing inflammation and aiding in the treatment of conditions like COVID. The video concludes with potential solutions for window design and the importance of outdoor exposure.
