The demand we put on the ventilation is that it shall function regardless of weather and wind, it shall not use more energy than necessary, meaning, it should be energy effi cient and economical to run. Our indoor air Recent years research shows that we are less productive when we breathe poor quality indoor air. In general we spend up to 70% of our time indoors and in colder climates such as some parts of...

3 buildings with electrical heating. Thereafter, the Building Regulations, BBR, Section 9:2 Energy Management will introduce more stringent demands on the specifi c energy consumption (kWh per m2 per year) of the building, and also limit the installed electric power in single houses with direct electrical heating as the main source of heating. The new regulations on energy management put great requirements on the design and workmanship. Ventilation, insulation and so on must be adapted to the lower energy use. A ventilation system that does not meet these demands or is poorly designed will...
