The Passive House concept refers to buildings with very little energy demand, meaning buildings with near zero consumption requirements (NZEB).

The constructive requirements of this type of buildings achieve an environmentally high quality interior, therefore, when we refer to Passive House we refer to homes with great comfort and health.

Originated from Germany in the 1980s, the Concept of Passive House certification has since spread universally.

In our Mediterranean climate zone there are already hundreds of houses and passive buildings built under this standard.

With the search of the optimization of the existent resources and with passive building techniques, a reduction of 70% in the air conditioning needs, both cold and heat is achieved when compared with the obligations of the current regulations (CTE).



Our studio is specialized in the design and construction of passive and sustainable buildings with little or no energy demand, achieving very comfortable and healthy spaces.  Our office carries out projects and advice regarding Passive House.

We collaborate with the client to achieve projects with sustainable and passive architecture, with almost zero consumption or with high energy efficiency.



Choice of terrain
With the client we visit and choose the best possible location for construction of the house, taking into consideration several factors such as orientation, sunlight, inclination, views, etc.

Constructive typology
We determine the construction system of the house, giving preference to industrialized elements and dry construction, with the aim of reducing time and costs.

Recommendation and choice of environmentally friendly and sustainable materials.




  1. High  thermal insulation
    By increasing the thickness of the insulation, it limits the energy demand for heating in winter and cooling in summer, to less than 15 kWh / m² per year.
  2. High quality window frames with multiple properties
    It is essential to have high quality window frames and glass that take advantage of the benefits of solar radiation in winter.
  3. Avoid thermal bridges
    The avoidance of thermal bridges results in high energy efficient buildings.
  4.  Controlled mechanical ventilation system with heat recovery
    It achieves a very healthy and high quality interior.
  5. Maximum airtightness
    This achieves energy savings, reduces condensation and contributes to greater acoustic insulation. It is possible to obtain less than 0.6 air changes per hour (sealing value 50 Pa) by applying a blowerdoor or envelope infiltration test on windows and doors.
  6. Demand PER
    The contribution of renewable primary energy (PER) or demand will be between 60 and 30 kWh / m² year:  photovoltaic, aerothermal and / or geothermal energy.



Bio Architecture is the concept of programming, projecting, realizing, using, demolishing and recycling in order to build sustainable buildings for people and the environment.  Sustainable buildings aim to optimize the energy and the materials which bring high advantages to the environment and to the economy. This allows a harmonic relation between humans and nature.

A house has to be adapted to us, as a third skin providng shelter, protection and health.

What is the third skin?

Our skin is the largest organ of our body, which protects us, cover us and also expose us to the outside environment. Our second skin is our clothes. Our third skin is our built environment.

We spend an average of 80-90% of our time indoors. The interior atmosphere may contain more that 900 chemical substances, particles and biologic materials with potential effect to our health. Being indoors, we are sometimes exposed to chemical and toxic substances, coming from different backgrounds, which can be significantly higher than being outdoors, due to poor ventilation.


Bio Architecture has 11 basic principles:

1. Understanding of our needs

2. Adjust the design to the local climate

3. Energy saving

4. Use of renewable energy

5. Water saving

6. Healthy materials: bio-compatible and hygroscopic

7. Use of sustainable local materials

8. Use of recycle materials

9. Avoid health risks

10. Manage construction residues

11. High quality buildings
