The building’s double skin closes itself during summer, while at night it opens to naturally ventilate the house
With a roof tilted towards the east, iranian based office BMDesign creates effective zones of negative pressure at the climax of the roof helping to ventilate the building naturally throughout most of the year. controllable vents, at the climax of the roof have a sucking effect, together with the large openings to the south of the building. air filters by flowing through a broken line of evergreen trees, over a pool in the outdoors and then by passing over an indoor garden of snake plants, which is known to be a great air purifier, and finally over a pond.

The home is finished in concrete except for the double skin on the sloped roof which is finished in new invisible tesla solar cells. the sloped roof will provide a large continuous surface for installing solar panels 30 cm above the roof, creating a double skin which can be opened or closed. during the cold winter days, the double skin roof opens itself to let the afternoon sun shine on the concrete roof and warm it up, while during the hot summer days, it closes itself to provide shade over the concrete roof as well as to produce clean energy by its solar cells.
