Decor : Passivhaus homes, an increasingly demanded standard

For some years now, the concept of passivhaus houses has entered the world of architecture with force. More and more studios are betting on this way of designing their projects, with the ultimate goal of caring for the environment and making use of sustainable energy. Such is the benefit of this method, that it is estimated that up to 75% of household heating and cooling consumption can be saved.

What is the Passivhaus standard?

passivhaus homes

When we talk about the Passivhaus standard, we are referring to the construction of houses and buildings designed to reduce energy consumption, in addition to making use of renewable energies. For the standard to be valid, it is necessary to comply with 5 basic principles:

Great thermal insulation

In this aspect, the envelope plays an important role, in which the exterior walls, the roof and the floor that make up the building or house must have a low level of thermal transmittance.

Windows and doors

For a house or building to meet passivhaus standards, the windows and doors to be installed must be of high performance. In general, the joinery used must have a very low thermal transmittance and the windows must be made of double or triple glass. The glass to choose will vary depending on the climatic conditions produced by the building’s sun exposure.

Dispense with thermal bridges

To carry out a correct passivhaus standard, a correct approach must be previously carried out to eliminate thermal bridges, in this way energy losses will also be avoided.

Air tightness

In conventional constructions, the air currents that can circulate through windows, holes or cracks cause some discomfort or cold to the tenants of the property.

In Passivhaus standards, the enclosure is designed to be as hermetic as possible, with the aim of achieving greater efficiency in the mechanical ventilation system and greater comfort.

Mechanical ventilation with heat recovery

In homes the tenants themselves and household appliances already generate heat, through the Passivhaus standard this same heat is used by the ventilation system. So just a small stove would be enough to condition the spaces, dispensing with other conventional systems such as radiators or underfloor heating.

Faced with the constant rise in the prices of the electricity bill and an imminent climate change, there are many who are already considering rehabilitating their home and moving to the passivhaus standard. But, it is essential that the company in charge of carrying out the construction has a certificate that certifies that it complies with the regulations of the passivhaus standard. Therefore, any company cannot carry out this type of building.

Precisely, the company Reformas Pamplona »Construcciones Ezkaurre is a benchmark implementing this construction standard that is so committed to the environment.
