6 important headlights for a passive house 1. Good insulation 2. Completely air tightened 3. Rational use of the sun 4. Energy friendly household equipment 5. Renewable energy sources (like sun panels) 6. Heat recovery

Good insulation § In Belgium the houses aren’t good insulated and that’s the reason why most of the heat escapes through the walls. § A passive house has insulation in the ground (20 cm), the walls (35 cm) and in the roof (45 cm).

Air tightened �The house must be completely air tightened, otherwise the cold air from outside can go inside and vice-versa. Strips that are placed to make the whole house air tightened

On this pictures they were testing if the house was realy air tightened.

Maximum use of the sun �For a maximum use of the sun it’s better that the windows are orientated to the south. �Use for example strong isolated and three double windows that’s give the sun the opportunity to come into the house. �Organize your house also that the house-hold devices give there warmth to the house.

Air quality �There is a gangway with tubes 2 meters under the ground that holds the temperature at a constant level of 12°C, in winter and summer times. �With a mechanical (low energy) ventilator the house is refreshed in only a couple of hours.
