Passive House What are they?

The construction of the future is the one that takes care of the resources of the present

Concept

A passive house is an efficient building that seeks to reduce energy consumption to a minimum thanks to its insulating elements and the incorporation of renewable energies, generating zero or almost zero consumption. Generally, this type of construction tends to reduce energy consumption by 90%. They are healthy houses that consume less than 10% of what your home currently consumes.

The "Passive House" in Spain are imposing. Every day more people choose to live in a home with maximum energy efficiency for its savings, comfort and respect for the environment.

It is another construction concept. It does not imply a specific style or quality, but rather the optimization of resources and design, both in the shape and orientation of the building and in closures and ventilation.

The 4 pillars of the Passive House building

Thermal isolation

The first point is the use of correct low-transmittance thermal insulation, which isolates the house from the outside, preventing heat from escaping in winter and from entering in summer. The insulation is placed in walls, enclosures or roofs, making the building envelope improve its thermal performance.

Avoid thermal bridges

The second point is to ensure that thermal bridges are not generated. Thermal bridges are weak points in the structure through which heat is lost, and which can be detected through thermography. Detecting and correcting these points is of vital importance if you want to achieve a Passive House.

Ventilation

It uses mechanical ventilation with high-performance heat recovery, which allows ventilation by recovering between 80 and 90% of the energy consumed. Thanks to these methods, it is not necessary to open the windows to ventilate, and the air that enters the house is heated, avoiding the unwanted entry and exit of heat.

tightness

Another aspect that becomes important in the model of our passive houses is airtightness. Airtightness refers to the fact that all the enclosures of the house ensure the watertightness of the house, achieving an airtightness effect that prevents heat loss.
