Mafra- Lisboa

In mainland Portugal, the Lisbon region enjoys the highest insolation values, exceeding 3,000 hours of sunshine per year. This abundance of sunlight was a key factor in shaping the programmatic concept of the project.

The unique geometry of the terrain, characterized by its larger side and natural south-facing slope, provided an ideal foundation for adopting a bioclimatic strategy. This facilitated the optimization of a high-performance passive design standard, an objective integral to both the property owner's vision and the project strategy from the outset.

The functional organization of the house reflects the local climatic conditions. All living areas are oriented toward the south, while circulation and auxiliary spaces are positioned to the north. This configuration maximizes solar gains through expansive glazing, complemented by shading solutions such as generous porches and solar pergolas to provide outside living spaces and effective protection during the summer months.

This design approach also minimizes the need for artificial lighting in winter, ensuring excellent natural light levels year-round.

The house was constructed using MAGU's ICF (Insulated Concrete Form) system, which enabled the creation of an interior space free from structural pillars, enhancing both functionality and aesthetics.

The mechanical systems of the house include a ZEHNDER ComfoAir Q600 HRV ventilation system, a domestic hot water (DHW) heat pump system by ENERGIE, supported by a Thermo Dynamic panel, and a Mitsubishi split unit providing supplementary centralized air conditioning in the living room, the central area of the house.

The house's design prioritizes passive principles, optimizing natural light, thermal performance, and energy efficiency. With 12 photovoltaic panels on the roof, it reduces reliance on active systems and promotes sustainability.
