The “Home with a Skin” project involves combining conservation of a traditional habitat, an integral part of local culture and family memories, with the need to convert these houses to make them energy efficient.

    Live from Solar Decathlon:

    To avoid demolition and reconstruction with their enormous environmental and financial costs, the “Home with a Skin” prototype proposes applying a second skin to these houses including, in particular, a passive solar greenhouse on one of their facades. The aim is to design a comfortable, ecological and sustainable habitat, while ensuring that its characteristics meet the needs of different generations, especially those of the elderly.
    This rehabilitation project applies to a road with strip houses built in 1963 in the village of Honselersdijk, 11 km south of The Hague. “Home with a Skin” anticipates producing as much energy and food as available areas allow by introducing fruit trees, berry bushes and vegetable planters.
    The detached house presented at Solar Decathlon 2014 is a small-scale replica of one of the houses to be rehabilitated. Built from wood panels, it features a double skin.
    A home automation system controls the house’s ventilation, solar protection, lighting and heating.

    Indoor solar protection Soltis 99 LowE
    Lightweight, durable and 100% recyclable, the 40 m² of Soltis 99 LowE composite screen is installed in the roof’s glazed extension.
    Soltis 99 LowE is also installed on the roof underside to control the house’s indoor thermal environment. The system is retractable and motorized to ensure its optimum efficiency.
    Combined with Type C double glazing, the Soltis 99 LowE screen guarantees unmatched thermal protection: its indoor solar factor is 34% compared with the 40% often exhibited by conventional references.
    Low emissivity Soltis 99 LowE screen represents a passive cooling source and contributes to improving the energy performance of the house: it curtails the “warm wall” feeling and re-emits less heat.
    The metal finish of Soltis 99 LowE screen, which reduces discomfort and dazzle, and its cleverly balanced openings ensure effective obstruction of the light flux. Luminosity is totally controlled and resident visual comfort is enhanced.

    The French manufacturing group Serge Ferrari is a leader in the flexible composite material sector.

    As the inventor of Précontraint Serge Ferrari technology, we design and manufacture flexible high performence composite materials for architecture, yachting protection, industry, furniture, equipment protection, health, environment and visual communication sectors.

    Précontraint Serge Ferrari patented technology


    This technological leap forward enabled the fledgling company to very quickly make a name for itself in the field of composite materials.

    Swiss made expertise


    Serge Ferrari’s Swiss production unit expertise is long-time recognised in the field of speciality products requiring “Swiss Made” top-of-the range quality, innovation and technology.

    Materials that meet major challenges

    Serge Ferrari composite materials are specified by major international architects because their lightness, low physical density and performance characteristics all contribute to a sustainable approach to construction. These materials combine insulation, translucence, lightness, strength and stability. In particular, Précontraint technology provides them with the best weight/performance ratio and long-term stability, enabling them to be fully in phase with mankind’s natural resources challenge: to do better with less and for longer.
