How can we create a comfortable and healthy indoor climate? The desired result is achieved when the various factors that influence the indoor climate – air, temperature, humidity, and the electroclimate – work together properly. This course provides an introduction to this complex topic. Many of these factors will be explored in greater depth in later courses, including “Building Materials and Building Science,” “Heating and Ventilation,” “Energy-efficient Building Design,” “Electromagnetic Radiation,” “Air and Pollutants,” “Light and Lighting,” or “Natural Colors and Finishes.”
