The term a "passive house" determines that the building is expected to need almost no energy at all. With Styro Stone it is possible to construct buildings, which even produce energy! In this case, Johannes Out, representative of Styro Stone Netherlands, built such a house in Leusden, in the centre of the Netherlands.
The trend is gathering momentum even in the UK with Styro Stone providing the shells for more Active Houses built there.

On the 15th of March "De Telegraaf", a Dutch national newspaper, described this utopia turned into reality: because it does not need energy,your house is the generator for your car, it produces a surplus enabling you to drive your car for 5,000 km annually. |
|
"Toekomstwoning" means future house; almost every Dutch newspaper had a "feeding frenzy" reporting about this event afterwards. |
|
The ground floor slab is insulated with foam glass. |
|
The walls are constructed with the Super-RR from Styro Stone. The U-Value of 0.14 was sufficient! |
|
To optimize the energy recovery in the ventilation system, coils are laid out for 60 m at a depth of 2m. |
|
The energy-recovery ventilation system is situated at the end of the garage, which is inside the house. Here, a 1,000 l tank serves for storing the energy. |
|
The house is air conditioned and heated using underfloor heating combined with the heat recovery ventilation system. |
|
The house is completely electronically controlled. |
|
In the Netherlands a steady wind helps to generate energy. |
|
A comfortable car to use inside the cities, without petrol/diesel fueled engine - only an envioromently freindly electric motor! |
|
It is charged with the surplus energy from the house. |
|
Johannes Out does not drive to work! |
