Owner approach of sustainability

The aim is to provide sustainable accommodation that promotes the health and well-being of users and that is environmentally friendly, not only during the construction process of the work, but throughout the life of the building

Architectural description

The architecture has been based on an eminently energetic rehabilitation but also deals with general aspects of sustainability: water management, responsible materials, innovation, good practices in construction, local promotion, respect for the environment and human health. The main thrust of this promotion has been the adaptability of housing and the participation of final users in the design and construction process of housing. The result: adapted, healthy and sustainable accommodation.

Energy consumption

  • 37,30 kWhpe/m2.year
  • 60,00 kWhpe/m2.year
  • RD: 47/2007

    During the first year the consumption is verified through monitoring of the building in order to verify actual consumption.

  • 80,00 kWhpe/m2.year

Envelope performance

  • 0,28 W.m-2.K-1
  • The building is formed by different types of enclosure, adapting to the existing initial composition: 0.28

    • Condensing gas boiler
    • Condensing gas boiler
    • No cooling system
    • Natural ventilation
    • Single flow
    • Solar Thermal
  • 30,00 %
  • The building does not have an air conditioning system, the natural ventilation system is enough to lower the temperature during the night in the warm season.

    The building has a cross-ventilation system that facilitates the natural thermal regulation, in addition to a thermal inertia thanks to the stone walls that act as natural regulators.

GHG emissions

  • 2,60 KgCO2/m2/year
  • Spanish Royal Decree: 47/2007

Indoor Air quality

    It is guaranteed by controlled forced ventilation.


    A photocatalytic painting is used for the interior painting of the whole building, an air purification system through a process called PHOTOCATALYSIS. It eliminates odors, fumes, viruses, bacteria, microorganisms, spores and other organic elements dangerous to health, and resolves the so-called "sick building syndrome".

    La qualitat del aire interior se controla a traves de una sonda que mide la concentració de CO2 en el aire






    Acabados / Suelo

    Parquet made of FSC certified, low carbon CO2 wood.

    On-site confirmation of sustainable production certificates.

Construction and exploitation costs

  • 240 840
