Zero-emission design: NZEB chalets .

In the picturesque setting of Val Chisone, in Roure, Orbyta Engineering has transformed an abandoned chalet into an NZEB (Nearly Zero Energy Building) chalet.

The project stands out for the harmonious integration of design, sustainability and energy efficiency, in full respect of the surrounding mountain context.

The renovation by means of demolition and reconstruction, maintained the original volumetry, but introduced cutting-edge materials and technologies.

The chalet, consisting of two units, combines tradition and modernity thanks to the use of local materials such as stone and lose, combined with high-performance plant engineering solutions

To ensure seamless integration with the alpine landscape and the village of Roure, the project involved the use of traditional materials and innovative techniques:

• local stone cladding: salvaged from the demolition of the existing building, they recall the traditional style of mountain buildings.
• supporting structure: reinforced concrete for the ground floor and solid wood for the upper level, ensure solidity and visual lightness.
• lose roofing: typical of alpine architecture, with strategic integration of the photovoltaic system.

This combination of materials and solutions resulted in a chalet that not only respects the environmental context but also enhances it, thanks to the large openings that offer spectacular views of the mountain landscape.

The project achieved high standards of energy efficiency through a high-performance passive envelope:

• brick blocks with basalt granules: provide excellent thermal and acoustic insulation, protecting the interior from harsh winter temperatures.
• Controlled Mechanical Ventilation (VMC): the Mitsubishi Lossnay system with enthalpy exchanger enables heat recovery from the extracted air, minimizing energy loss.
• heat pump: the air treatment system uses a small outdoor unit with a maximum consumption of 800 watts, almost entirely covered by the photovoltaic system.
• 15 kWp photovoltaic system: located on the roof, it provides renewable energy to power indoor systems and reduce CO2 emissions
