Sustainability

The construction sector is one of the main causes of climate change, so it is necessary to design buildings with new criteria.

Energy consumption, together with the comfort and health of its users, are essential values in the spaces we design.

The following standards certify ROA’s commitment to sustainability: NZEB, BREEAM, WELL, LEED and VERDE.

WEAVING LA BORDETA IS SUSTAINABILITY

A nearly zero-energy building (nZEB) is envisioned, offering clear environmental, social, economic, and programmatic benefits. Designed with recycled materials, it can be built in just six months. This approach not only speeds up construction but also reduces CO₂ emissions by 32%.

Flexibility is key. On the ground floor and basement, commercial spaces can be adapted according to demand, allowing for anywhere from 1 to 8 units in the same area.

Inclusion is a priority: 60% of the residences are adapted for people with reduced mobility, ensuring accessibility from common areas. The design fosters community living with outdoor spaces at different levels and a green roof with urban gardens, promoting social integration and connection with nature.

Additionally, the building incorporates passive climate control systems, solar panels, and rainwater collection tanks for irrigating green areas, achieving minimal environmental impact.

An innovative, efficient, and sustainable project. Because the future of construction is fast, eco-friendly, and designed for everyone.

WOODEN HOUSE WITH A VIEW

The project is located on a mountainous slope in Sant Fost de Campsentelles, offering stunning mountain views.

The house sits on the terrain with minimal impact. A wooden structural system on stilts anchors the home while preserving the existing vegetation. This approach fully conserves the environment, avoiding major earthworks that would alter the landscape.

Wood and stone are the chosen materials. Stone helps integrate the project into its surroundings, while wood adds warmth and beauty to the spaces, along with numerous benefits. As a renewable resource, wood contributes to sustainability by reducing the carbon footprint. It is also an excellent insulator, leading to lower energy consumption—especially in mountainous areas—and allows for faster assembly, speeding up construction.

Functionally, the house is designed to enhance the connection with its surroundings. Next to the north-facing main entrance are the service areas and the vertical circulation core with the staircase. This layout allows for a large window on the ground floor, seamlessly connecting the open-plan living-dining-kitchen area with the outdoors, offering breathtaking mountain views. On the upper floor, all rooms are oriented south to maximize natural light.

SUSTAINABILITY

MUNICIPAL CENTER OF CUNIT

The new double-height main entrance monumentalizes the building and creates a porch space with triple access, open to Plaza de Cataluña. The exterior of the building is covered with a ceramic and vegetal skin that provides thermal insulation and visual comfort.

The theater of the center, which requires darkness, is relocated from the upper floor to the basement. This repositioning enhances the architectural qualities of the space and its acoustics. Retractable bleachers give the space great versatility.

All floors gain natural lighting, and the multipurpose hall acquires views of the Church of San Cristóbal.

From an energy perspective, efficient climate control is achieved through a mixed system of passive contributions and renewable sources. Through Canadian wells, air is recirculated inside, increasing or decreasing the temperature by up to 5ºC. Construction waste is repurposed as raw material in the new design, reducing CO₂ emissions by 32% in the life cycle analysis (LCA). The highest energy efficiency rating is achieved, with almost zero consumption.

These strategies will improve the building’s conditions, strengthening the social and cultural life of the citizens of Cunit.
