Passive homes are energy-saving zero-consumption homes.
Passive houses or what is the same “Passivhaus” is a type of construction that emerged in Germany in the 90s. This type of housing was based on combining high internal comfort with zero energy consumption and a very low expense.
A passive house is a comfortable and above all healthy house,where it ensures a high quality in the air that is breathed and in the temperature it has.
Passive housing is a combination of bioclimatic housing with very high energy efficiency. The passivhaus are designed to make the most of natural light and solar radiation, and they also have an insulation superior to a normal house and use air renewal systems that do not use another type of housing.
What are passive houses based on?
Passive houses have high thermal insulation
A house with poor thermal insulation can lose up to 30% energy, therefore, one of the characteristics on which passive houses are based is in the perfect insulation with the aim of reducing heat loss in winter and gaining it in summer.
Passive houses eliminate thermal bridges
Thermal bridges are the ones that cause the heat to be lost in the buildings. In passive houses we study how to put layers of continuous insulation, to avoid that loss of heat.
They have doors and windows with the best features.
Between 25% and 30% of the cost of heating in a home is due to the loss of heat through the windows and enclosures either because it is an advantage with very low performance or because it is poorly installed, therefore , a window of good quality and with a correct installation is fundamental in a passive house.
Passivhaus ventilate to recover heat.
In passive houses a double flow ventilation system is installed with the aim of achieving high air quality, thermal comfort and energy savings. We advise that with this system and a small and additional heat supply that we give in addition to an installation of underfloor heating of low consumption in some room of the house such as the bathrooms, we will get the systems of the house eliminated Traditional heating of great consumption.
Passive houses control airtightness.
The holes that a building can have and are the cracks and gaps are those that cause condensation in the construction of the house. In passive houses, good air tightness increases comfort and decreases air loss. Passive houses guarantee thermal comfort, with a high constructive quality.
They are planned and designed homes.
Passive houses are homes that have an intelligent and bioclimatic design. A passive house has a pleasant temperature throughout the year and it makes good use of natural light. These are homes that require less energy to heat and cool the home and to light it than a normal house.
What is Passivhaus Certification?
Passivhaus certification is the union of technical tests and certification as the only guarantee that the building meets Passivhaus requirements. It is the only thing that guarantees that the building meets the requirements of Passivhaus Institut of Germany and the level of comfort and internal and energy quality of the house.
