Energy efficiency

Warming the building by using natural sunlight is called Passive Solar heating.

In this case we use advanced windows, such windows have triple blades with E-low system.

• Passive sun Heating

Energy efficiency• Thermal bridge

The other types of Natural Insulation Materials are:

• Wood Fibre

• Expanded Clay Aggregate

• Sheep's Wool

• Flax and Hemp

Energy efficiency• Sustainable and alternative insolations

• Sustainable and alternative insolations

Energy efficiency

Insulation is a key component of sustainable building design.

Cellulose InsulationA recycled product made from newsprint and other cellulose fibre.

19

Building services• Double flux ventilation

- Solution long-term economic.- Use of unnecessary heat stored at the ceiling.- Homogenizes the temperature.- Air is cleaned and prevents health problems.

20

Building services• Equipment housing with a double flow ventilation

Heat exchanger - recovers heat (60%)

Solar panels system - save electricity for the VMC - new heating source

21

Green Roof

Extensive green roof - Biodiversity - Insulation - Accessible

Drain water system from the roof to the tank in the basement.

22

Rain water systemWater management

Sanitaryware saving water - Valves with flow limiter - Dual control flush toilet - Hot water halfway kitchen bathroom - Decrease volume flush

Rain water system - Storage in the basement (inertia): - Contribution garden, cars - Evacuation in a pond (Biodiversity)
