The Passivhaus standard has 5 essential principles.
These 5 principles work together to guarantee the final performance of the building. In order for the performance to be as estimated, the Passivhaus principles must be verified both during the design and, fundamentally, during the construction process.
Excellent thermal insulation
In Passivhaus, a key factor is to achieve an enclosing with a very low thermal transmittance. To achieve this, it is necessary to place abundant thermal insulation on the walls, floor and ceiling of the building.
Absence of thermal bridges.
Thermal bridges are points of the building where the thermal transmittance is greater, producing considerable energy loss in them. They are generally produced by a discontinuity in the insulation. Passivhaus requires minimizing thermal bridges throughout the construction, allowing the ontinuity of the insulation. Thermal bridges also generate cold spots inside that can cause humidity, damage to materials and loss of interior comfort.
High performance carpentry
Passivhaus buildings require the use of high-performance, insulated and airtight windows and doors. In the case of windows, two and up to three panels are used, the exterior ones being low emissive with a chamber filled with inert gas. This guarantees a very low thermal transmittance, great acoustic insulation and a reflection or maintenance of energy in the different seasons.
Air tightness
Contrary to the belief of professionals in the construction sector, most of the energy in a building is lost by convection (fluid movement, in this case air) and not by conduction (heat transfer through a material or several). For this reason, in Passivhaus it is essential to guarantee tightness to outside air, that is, to minimize the so common infiltrations. To achieve this hermetic envelope, it must be studied during the project and verified during the works that there is a continuous air barrier on the façades, roof and floor that guarantees watertightness.
Mechanical ventilation with heat recovery
Although, if we create a sealed enclosure, for health reasons it will be necessary to guarantee the renewal of the interior air. For this, in Passivhaus projects, we need to incorporate a double-circuit mechanical ventilation system which, in this case, will incorporate a heat recovery system that allows us to minimize energy losses. In certain climates, thanks to the heat recovery, it is even possible to air condition the buildings only using the ventilation and without the specific air conditioning systems. One of the advantages of mechanical ventilation, in a context of extreme alert for contamination, is that it allows us to control its quality much more precisely, treating it when necessary.
We manufacture and build in a way that is respectful of the environment, healthy, sustainable and with maximum energy efficiency. We use wood as the main structural element. The European Directive 2010/31 requires the member states of the Union that all their public buildings as of December 31, 2018 be Nearly Zero Consumption Buildings (ECCN), and that all buildings without exception be as of December 31 December 2020.
When manufacturing housed we are aware of the environment and we comply with the European Directive.
Minimizing energy consumption
The industrialization of our construction process reduces the number of transports of materials to work with the consequent saving of resources that this entails. We optimize the use of materials without producing hardly any waste. Minimizing the production of debris or waste thanks to our dry construction system. Using reusable and recyclable materials.
Saving on energy consumption. We achieve a significant reduction in thermal transmission in our homes both in summer and winte




Our company manufactures to measure following the Passivhaus standard, we do not have a specific design, we make each house with the measurements and distribution that the client needs and to their liking, it is the client who defines all the aesthetic aspects. On the other hand, the house has to be adapted to the climate of each area, we take into consideration fundamental issues for thermal behavior, its orientation and its geometric and topographic conditions, issues such as wind, rain, snow, humidity, the plot, municipal regulations, etc.
About Project
Passive House Spain
“The cheapest and cleanest energy is the one that is not
Consumed”
The Passivhaus standard is the most demanding energy efficiency standard in the world. It is focused on minimizing the energy consumption of buildings while maintaining high levels of comfort inside.
