Tesla appears to be taking aim at revolutionizing homeownership and architects are taking note. Hot on the heels of Tesla’s eagerly awaited solar roof, Tehran-based BMDesign Studios created Alavi House, a home in Isfahan, Iran that’s to be finished with Tesla’s new and seemingly invisible solar cells. Optimized for solar, the Alavi House will produce more energy than it needs and feature a smart and operable double-skin to promote natural heating and cooling of the home. Named after its clients, the 550-square-meter Alavi House is proposed for a site at the foothills of the Zagros Mountain range at the edge of a desert . Due to the arid climate, the architects used the prevailing winds from the south and southwest to inform the roof’s sloped shape and direction. “With a roof tilted toward East, we can create effective zones of negative pressure at the climax of the roof helping to ventilate the building naturally through most of the year,” wrote the architects. “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 (Cedrus deodara) and over a pool in the outdoors and then by passing over an indoor garden of Snake Plants (Sansevieria trifasciata) which is known to be a great air purifier (NASA Clean Air Study) and over a pond.” Related: Tesla’s new Solar Roof is actually cheaper than a normal roof The home is finished in concrete save for the double skin on the sloped roof that would be clad in the nearly imperceptible Tesla solar cells installed 30 centimeters above the roof. The operable double skin roof can rotate open to allow the sun to heat the concrete roof and warm the interior. Alternatively on colder days, the roof rotates close to provide shade from the sun, while simultaneously optimizing conditions for generating solar energy. The 194-square-meter solar roof would feature 104 solar modules capable of meeting a minimum of 29,000 kWh a year, far exceeding the average electricity consumption of an Iranian household. Insulated glazing wraps the building on the south side to let in natural light and frame views of the cherry orchard and mountains. Communal areas are placed on the ground floor and include a tv room, kitchen, dining room, and bathroom that are connected to an indoor landscaped area and pool next to the outdoor pool. The upper level contains two master bedrooms and library. + BMDesign Studios Via highsnobiety Images via BMDesign Studios

Bowl-shaped roofs harvest rainwater and promote natural cooling in arid environments

Water scarcity is felt unequally throughout the world with some regions worse off than others. Iran-based BMDesign Studios addressed their home country’s arid climates with an architectural solution to water shortages called Concave Roof, a double-roof system designed to collect and store rainwater, and promote natural cooling. The Concave Roof was engineered for arid environments, where rainwater collection can be tricky due to higher than average evaporation rates and low annual precipitation. The double-roof system, which includes a domed roof beneath a bowl-shaped catchment area, is designed to “help [make] even the smallest quantities of rain [flow down] the roof and eventually coalesce into bigger drops, just right for harvesting before they evaporate,” said the architects to ArchDaily . Stacking a concave roof atop a convex roof promotes natural cooling through shade and wind movement between the two roofs. Related: Rammed earth house blends traditional materials with modern techniques in Vietnam’s last frontier The bowl-shaped catchment area is steeply sloped to move raindrops towards a central collection point, where the rain is funneled into reservoirs . The reservoirs are placed between building walls to help regulate indoor temperatures. With this system, the architects estimate that 28 cubic meters of water could be harvested with just 923 square meters of a concave roof surface. BMDesign Studios’ vision also goes beyond the double-roof system and includes a massing design where the buildings and courtyards are sunken to promote natural cooling. The buildings would be organized around atriums to promote circulation and community. + BMDesign Studios Via ArchDaily Images via BMDesign Studios
