Energy-intensive building

Detached house situated in Muros del Nalon that integrates both the concepts of the Passivhaus standard energy efficiency and bioclimatic architecture. This way the building guarantees an almost zero energy consumption. The housing is formed by two different volumes, which are arranged according to different orientations, the prevailing winds and views, and are adapted to the shape of the plot and alignments marked by urban planning. The north facade is almost blind, avoiding energy losses. South façade has large windows in the living room, kitchen and master bedroom, promoting solar gains in winter. In summer the house is protected by shadings and temporary protections. As for the materials used, the architecture of the fishing villages of the Asturian western coast, are formed by volumes of different colors and wooden galleries. These two materials are reinterpreted and are used to coat the housing: the volumes where the rooms are located are coated externally with continuous Siberian Larch wood  both façade and roof. These wooden pieces are based on a white pedestal in which day and access areas are located.

Owner approach of sustainability

Detached house situated in Muros del Nalon that integrates both the concepts of the Passivhaus standard energy efficiency and bioclimatic architecture. This way the building guarantees an almost zero energy consumption. The house is projected according to the criteria of the standard Passivhaus, in a way that energy consumption is adapted to the unique operation of housing. This way, the two volumes, can operate independently and have an energy consumption depending on the different degrees of occupancy of the house.

Architectural description

The housing is formed by two different volumes, which are arranged according to different orientations, the prevailing winds and views, and are adapted to the shape of the plot and alignments marked by urban planning. The north facade is almost blind, avoiding energy losses. South façade has large windows in the living room, kitchen and master bedroom, promoting solar gains in winter. In summer the house is protected by shadings and temporary protections.

Indoor Air quality

    The house is equipped with a mechanical ventilation system controlled double-flow ventilation (balanced passive house). The heat exchanger installed is the Siber DF4 Excellent model, certified by the Passivhaus Institute with a yield of 84% and a maximum ventilation capacity of 400 m3 / h. The nominal performance of this system, taking into account losses in the ducts between the heat recovery device and the thermal envelope is 83%. Outside air ducts (input and output) are isolated and out to facade. The heat exchanger, is placed in the utility room on the ground floor, outside the thermal envelope. The supply and exhaust pipes run both ground floor and first floor by the wrought facilities coffin is insulated with rock wool 12 cm thick. of thickness. Air supply grilles are placed directly on the floor and are located in the living room and bedrooms, and extraction grilles are placed on the walls to 30cm from the ceiling in the bathrooms and kitchen.

Comfort

    Thanks to proper insulation, airtightness and mechanical ventilation double flow own homes certified Passivhaus great interior comfort and low CO2 concentration is achieved inside.
