Final Result
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.
Energy efficiency Thermal bridge 1 Coating 2 Masonry wall, solid concrete 3 Adhesive smoothing 4 STYROFOAM IB-A 5 Inner coating 6 Concrete pillar
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
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.
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.
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
Green Roof Extensive green roof - Biodiversity - Insulation - Accessible Drain water system from the roof to the tank in the basement.
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)
Rain water system Water management Operation of Equipment to Capture Rainwater
