The NIU project was conceived with the ambition of democratizing architecture by making it both sustainable and affordable. The systematization of the construction process reduces both execution time and costs while maintaining a high level of precision and quality.
The house is organized over two levels according to a clear and functional layout. The ground floor accommodates the day areas, while the upper floor contains the more private spaces. Between them, a compact core of circulation and services organizes the program and articulates the spatial sequence, optimizing both the spatial arrangement and construction efficiency.
The house is built using a lightweight steel structure. We understand open systematization as a lightweight construction system that clearly distinguishes between the structural function and thermal insulation. Rather than relying on mass as the traditional strategy for environmental performance, the project employs high-performance, lightweight insulating materials, recalling Buckminster Fuller's famous question: "How much does your building weigh, Mr. Foster?" Perhaps reducing the weight of architecture is one of the most effective ways to make it truly sustainable. The building envelope is conceived as a ventilated façade, while the interior is entirely finished in timber.
The house is designed to be oriented along a north-south axis, promoting efficient cross ventilation and optimal bioclimatic performance. This orientation passively enhances indoor comfort while reducing energy demand throughout the year.
A bioclimatic pergola allows solar radiation to penetrate during winter while providing shade in summer. These intermediate spaces blur the boundaries between indoors and outdoors, extending the usable living area and enabling new forms of occupation within the transitional zones.
The difference in level between the natural terrain and the building platform is resolved through a ventilated crawl space. By recirculating ventilation air through this cavity, the system transforms it into a contemporary reinterpretation of the Roman hypocaust, turning the floor into a radiant surface that can contribute to both heating and cooling, depending on the season. At the same time, it acts as a passive thermal recovery system, improving the building's overall energy efficiency and reducing its heating and cooling demand.
The environmental strategy is completed by a water recovery system that collects condensation produced by the air-conditioning equipment. This water is reused to supply the house's wet areas and irrigate the garden, reducing potable water consumption while integrating the building's different systems into a more efficient resource management cycle.
