Final Result

14

Energy efficiency • Passive sun Heating 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.

15

• Thermal bridge Energy efficiency 1 Coating 2 Masonry wall, solid concrete 3 Adhesive smoothing 4 STYROFOAM IB-A 5 Inner coating 6 Concrete pillar 16

Energy efficiency • Sustainable and alternative insolations The other types of Natural Insulation Materials are: • Wood Fibre • Expanded Clay Aggregate • Sheep's Wool • Flax and Hemp 17

Energy efficiency • Sustainable and alternative insolations Insulation is a key component of sustainable building design.

Cellulose Insulation A recycled product made from newsprint and other cellulose fibre.

18

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.

19

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 20

Green Roof  Extensive green roof - Biodiversity - Insulation - Accessible  Drain water system from the roof to the tank in the basement.

21

Rain water system Water 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) 22

Rain water system Water management Operation of Equipment to Capture Rainwater 23
