Energy Savings in Buildings

This lecture covers the topic of energy savings in buildings, focusing on passive measures. It explains the Swiss energy transition, the building as an energy system, energy consumption for various purposes, passive measures versus active systems, the concept of grey energy, building insulation, thermal imaging for heat loss detection, energy balance in buildings, the Energy Expenditure Index (IDE), and the importance of building renovation. It also discusses the use of passive solar energy and concludes by emphasizing the potential of passive measures, the decreasing thermal losses in modern buildings, the need for building renovation, the benefits of solar-oriented architecture, and the importance of addressing thermal bridges.
