Community Added Value Center by CIMBRA: A Sustainable Approach to Vernacular Architecture

Blending Tradition and Innovation in Sustainable Design

Located in Caimancito, Argentina, the Community Added Value Center by CIMBRA exemplifies how vernacular architecture and modern sustainability principles can coexist. Designed with a deep respect for indigenous knowledge and regional construction techniques, this 45 m² structure serves as a hub for community engagement, agroforestry, and social development.

Inspired by the traditional Culata Jovai typology found in the Chaco countryside, the center incorporates a continuous shaded space supported by a column-horcón system, ensuring thermal comfort and a cohesive spatial experience. By integrating bioclimatic strategies, locally sourced materials, and participatory design processes, CIMBRA has crafted a building that fosters resilience and self-sufficiency.

A Climate-Responsive Architectural Solution

At the core of the design lies a deep understanding of the local climate and the integration of passive cooling strategies. The structure leverages:

• Cross-ventilation for natural airflow and temperature regulation.
• Vertical sunshades designed with regional "envarillados," reminiscent of Guarani fences.
• Galleries and shaded spaces that transition seamlessly between indoor and outdoor environments.
• Wattle and daub walls, a traditional earth construction method that enhances insulation and moisture regulation.

These elements work collectively to mitigate the effects of high temperatures while maintaining a comfortable indoor environment without relying on mechanical cooling.

Sustainable Water Management and Ecological Practices

A fundamental aspect of the project is its water harvesting and conservation system, which includes:

• A shade roof that collects and channels rainwater.
• A storage reservoir to ensure sustainable water access.
• Ecological wastewater treatment systems for responsible resource management.

These initiatives align with circular construction principles, minimizing environmental impact while ensuring long-term community benefits.

Participatory Design: Empowering Local Communities

A key feature of the project was the collaborative construction process with the Guarani community Arete Guazú. Through hands-on workshops, local knowledge in both architecture and agriculture was integrated into the design, reinforcing cultural identity and self-reliance.

The center also incorporates spaces dedicated to agroforestry, promoting food security and environmental stewardship. This holistic approach ensures that the architecture not only serves as a shelter but also supports livelihoods and ecological balance.

Earth Construction: Harnessing Natural Materials for Resilience

The use of quincha (wattle and daub) technology reflects a commitment to low-carbon construction. The technique involves:

• A wooden framework supporting a cane lattice.
• The application of earth mortar, forming lightweight but thermally efficient walls.
• Natural stabilizers in plasters and paints, enhancing durability against abrasion and erosion.

This traditional method optimizes hygroscopic capacity, allowing the walls to absorb and release moisture, thus regulating indoor humidity levels naturally.

A Model for Sustainable and Contextual Architecture

By prioritizing local materials, indigenous craftsmanship, and climate-sensitive design, the Community Added Value Center exemplifies an architectural model rooted in place and purpose. This project underscores the importance of integrating social technologies that enhance water security, energy efficiency, and overall well-being.
