06 Feb Brazilian home uses solar energy for 100% self-sufficiency
Brazilian firm 24 7 Arquitetura has set a stunning modern home into a challenging mountainous landscape in Brazil’s Nova Lima region. In addition to the home’s contemporary aesthetic, which is comprised of several exposed concrete blocks, the residence is completely self-sustaining thanks to its massive rooftop solar array that generates all the power the home needs.
Located north of Rio de Janeiro, Nova Lima is a mountainous region known for its mining sector. The area is marked by rugged low and high-rising topography covered in lush vegetation. Although the undulating landscape presented several challenges for the 24 7 Arquitetura team, the architects managed to use the natural layout to the benefit of the contemporary home.
According to the architects, the solution to the building lot’s slope was to set the home’s main social areas at the highest elevation possible, jutting out of the sloped hill, but above the tree canopy. This allowed the main living area to open up to a large outdoor space with a swimming pool and outdoor lounge area.
Building the home into the landscape also led the design to be slightly tilted to the east, which enables the home’s interior to be shaded from the harsh sun rays during the summertime. Additionally, the designers planted two trees in the middle of the home’s outdoor deck to provide additional shade and let natural light subtly filter into the living spaces.
The first floor of the home was built out to house the garage, laundry facilities and extra storage while the second floor is at the heart of the home. The large open-plan living area opens up to a large deck via massive sliding glass doors, leading to the infinity swimming pool. The top floor houses the master bedroom with an ensuite bath and open-air balcony space to take in the stunning views.
At over 4,000 square feet, the home is a massive structure that requires a lot of energy. Thankfully, this energy is produced by a large rooftop solar array that produces about 1400kW per month. This not only generates enough energy for the home, but also for heating the pool water.
