We imported bricks from a company called LIAPAN, because these bricks can be produced in Brazil and they are not burnt as the ones we have on the market, which will help reducing the CO2 emission from brick companies.
The main focus is to improve Brazilian building standards construction to make people pay more attention to air quality, thermal comfort, energy spending, amongst others.
The house is located at SENAI, which is a school focused on developing construction labor (from Brick layers to Construction coordinators). This pilot project will be used to spread Passive House technologies: it will serve as a seminar room for hand labor, engineers, architects and anyone who is curious about it.
We also want to use this building to convince local manufacturers to produce the required high performance components. This will have a social impact, with the creation of new jobs and knowledge sharing.
In this project we also have an irrigation system (EcoRain – Germany) which can save up to 70% of water for grass irrigation, the whole system is automated. This system is way better than what we have available on our market because it avoids the over use of water because of evaporation, and also guarantees that every part is irrigated with the same amount of water (differently than the spliclers we have available).

It's made out of clay and it's not burnt during its fabrication process.
We decided to use a material which can be produced in our regions (bricks made out of clay). For this house we imported all the bricks from Germany, but at the moment we are looking for manufacturers to start producing the bricks in Brazil.
