Sustainable dwelling in Brazil Ubatuba by PITTA Arquitetura

Ubatuba is located on the Brazilian coast, between Rio de Janeiro and Sao Paulo. It is one of the best-preserved biospheres in the country. This is a location chosen jointly by real estate development company BIO Empreendimentos and PITTA Arquitetura to create sustainable model homes. The project aims to encourage neighbourhood residents to adopt a “greener” lifestyle and incorporate sustainable development technologies into their homes to reduce environmental damage and pollution. It will also serve as an experiment to validate new building technologies.

In order to reduce the disturbance of the house to the environment, the designer decided to insert the house into the plot. Ensuring that the house is in contact with the thriving natural environment is at the core of the design. Among these options, the bioclimatic strategy is also a priority because the local climate is humid, hot summers and abundant rainfall. The design process must be guided by comfort.

Raising the floor of the house helps keep the house dry, improves air circulation, and lightly steps on the site. High ceilings and large openings promote natural ventilation and effectively reduce indoor temperatures.The simple palette of concrete, wood and steel blends the house with its surroundings.

The house is designed to maintain a comfortable indoor temperature and protect it from the strong afternoon sun throughout the summer. The bedroom has morning light, while the overhangs and foliage protect the living room from the hot summer sun. In winter, as the sun’s height angle becomes smaller, sunlight from high north-facing windows falls on concrete walls and floors, absorbing heat during the day and releasing heat at night.
