Kamanchaca House is a residential architectural project situated in Casablanca, Chile. This design reflects a sophisticated approach to addressing local climatic conditions, particularly focusing on the fog phenomena that the region experiences. The architecture emphasizes both functionality and sustainability through innovative design strategies, making it a notable addition to contemporary building practices. The primary purpose of the Kamanchaca House is to provide a comfortable living space while efficiently utilizing natural resources.

The design incorporates an elongated hexagonal polyhedron form, optimizing spatial organization and enhancing natural light penetration. The dwelling is organized into distinct living spaces that foster a harmonious flow, facilitating social interactions among residents. These include a multi-purpose living area, a compact kitchenette, and private sleeping quarters, each strategically positioned to maximize utility and comfort.

Unique Use of Fog as a Resource

One of the defining characteristics of Kamanchaca House is its innovative water collection system that harnesses atmospheric fog. The architecture features a specialized fog-catching mechanism that can capture approximately 4.3 liters of water per square meter daily. This system directly addresses the pressing issue of water scarcity in the area, highlighting an important connection between architecture and environmental resources. The design utilizes passive strategies for thermal regulation and ventilation, further enhancing the sustainability of the dwelling.

The material selection is another aspect that differentiates this project. The structure is primarily built from recycled polyvinyl chloride (PVC), wood, and metal, selected for their durability and performance under local weather conditions. The use of recycled materials minimizes environmental impact, aligning with contemporary sustainable design principles. This attention to materiality not only contributes to resource efficiency but also provides aesthetic value throughout the dwelling.

Integration of Passive Design Techniques

The Kamanchaca House employs passive design techniques that promote energy efficiency, utilizing natural light and cross-ventilation to enhance the internal climate. The arrangement of windows allows for optimal sunlight exposure, reducing reliance on artificial lighting during the day. These architectural elements contribute to the overall energy performance of the house, ensuring a minimal carbon footprint.

In addition, the integration of photovoltaic systems enables the house to generate its own energy, further reducing dependence on external power sources. The thoughtful configuration of rainwater harvesting systems complements the fog collection approach, ensuring water availability throughout the year. This project exemplifies a comprehensive understanding of the relationship between architecture and the environment, utilizing innovative approaches to create a sustainable living space.
