Technical requirements must be respected to guarantee a better insulation, better energy production, smarter use of environmental parameters such as sunshine, ecological use of materials, or even a combination of all these parameters to reach an energy consumption target.
Portugal has set itself the target of carbon neutrality by 2050. The obligation is to drastically reduce energy consumption with a target of 12 kWh/m², per inhabitant/year, with the obligation to use renewable energies such as solar or photovoltaic panels. In other words, it means an energy consumption divided by four compared to that of today.
Besides the reduction in energy consumption, the other fundamental objective is to obtain thermal comfort in a natural way by using architectural means, the renewable energies available and by avoiding as much as possible the mechanized technical means and fossil energies.
The bioclimatic strategy aims to be warm in winter without heating and stay cool in summer without having to use air conditioning, regardless of the geographic location.
Architectural design is therefore the key to making the most of the sun in winter and protecting yourself from it in summer.
Our houses have very high thermal performance, can easily be passive (without energy consumption) or positive (energy producer). The temperature is uniform whatever the season: with 40 degrees outside, the house will maintain 22 degrees inside and with 0 degrees outside, the house will easily be at 19 degrees without any heating.
We do this thanks to several factors:
· Exceptional thermal insulation: with 30 cm of EPS insulation, the coefficient of thermal transmission is the lowest that exists. There is therefore no heat or coolness that passes through the walls, the floor or the roof. With this insulation, the building uses up to 90% less heating or air conditioning than a traditional building;
· There are no thermal bridges thanks to the wooden structure;
· The houses are airtight thanks to the OSB panels fixed inside the structure. All walls and windows are sealed with sealing tape.
