Reduction of Internal Heat Sources

In "Passive Houses", the energy use and the behaviour of the tenants is much more important. To avoid overheating during summer all energy losses of electrical equipments should be minimized. In offices, in particular, low energy PCís, monitors and electrical lighting should be used. The reduction of stand-by-losses, reduced temperature in the warm-water-system, use of energy efficient electric equipment and natural lighting (using the daylight) obviously support CO2-reduction and therefore mitigation as well.
