The passive house is a building standard, which focuses the building to virtually zero energy expenditure, while generating an optimal level of well-being inside the house, at any time of the year.
The concept began to be studied in Germany in the 1980s and spread around the world in many buildings, whether residential and commercial.
This type of building consumes up to 7 times less energy than a traditional construction, and its construction is focused and designed to make the most of sunlight in the winter and keep warm inside.
Passive houses thus become an economical option, since in the long term economic savings are achieved thanks to the low artificial consumption they require. If we also use healthy and natural materials, it will be the ecological house par excellence.
To achieve this energy efficiency and comfort inside, Passive-house-certified constructions are based on 5 basic principles.
Thermal insulation, the greatest ally to conserve the temperature inside the house,.
The prevention of thermal bridges, which are those points at which the insulation is weakened, which if we avoid will eliminate energy losses.
Air tightness, since controlling air infiltrations, we will get a much more efficient building.
Ventilation with heat recovery, requiring controlled mechanical ventilation to renew the air.
Windows of great performance, optimizing the placement and materials so as not to lose energy unwanted.
