A Sedum roof, on the garage, provides natural insulation, and drainage, whilst also providing environmental and ecological advantages for flora and fauna. In many countries "Sedum" is obligatory for fkat roofs
A "Maison Passive", Les Yvelines, near Paris, France. Home of Eric and Ikuko Lente and their children Anakin and Yulis. Only need ten small sacks of wood to help heat the house over a whole winter period, otherwise the house is heated by the sun's rays through the windows, and is virtually self-sufficient. Windows are triple glazed and doors triple stepped for optimum insulation. Hot water is made by natural convection roof panels through solar water heating. The house uses so little energy that the family sells electricity from solar panels€2000 to the grid. The house is entirely insulated and covered in wood inside and out. Flat roof is covered in Sedum plants for ecological, insulative and drainage. All solar, heat exchange and water controls are easily accessed inside the house.
The term passive house (Passivhaus in German) refers to a rigorous, voluntary standard for energy efficiency in a building, reducing its ecological footprint. It results in ultra-low energy buildings that require little energy for space heating or cooling. Passive design is not an attachment or supplement to architectural design, but a design process that is integrated with architectural design.
Une maison passive est un bâtiment économe en énergie. Les pertes de chaleur sont tellement limitées qu’un faible apport de chauffage est suffisant. La puissance d’un fer à repasser (+- 2000 W), permet de chauffer confortablement une maison pendant l’hiver ! Pendant l’été, les pare-soleils évitent la surchauffe de l’habitation. Une maison passive consomme en moyenne 4 fois moins d’énergie.
Pour réaliser cela il faut d’abord isoler. Il y a généralement entre 25 et 35 cm d’isolant sur les murs, 20 cm pour les sols et 40 à 45 pour les toits, selon le type de
