Passive Cooling and Natural Ventilation in a Sustainable Adobe Residence

Project in-detail

Utilizing adobe's thermal mass and a passive cooling ventilation tower, the design achieves energy efficiency and environmental sensitivity while serving as a self-sufficient desert residence.
5 key facts about this project
01
Utilizes local adobe to enhance thermal mass and energy efficiency.
02
Incorporates a passive cooling ventilation tower for improved air quality.
03
Features a greenhouse integrated into the living space for indoor cultivation.
04
Employs a greywater recycling system for sustainable water management.
05
Designed with flexible spaces to adapt to changing family needs.
The (H)OFF-GRID house is an architectural project focused on sustainability and self-sufficiency. Located in a desert environment, it aims to create a residence that functions independently by optimizing energy and water management systems. The design reflects an intentional integration of modern techniques with traditional methods, contributing to a reduced environmental impact while providing a comfortable living space for its occupants.

The architectural concept prioritizes functionality while maintaining an aesthetic connection to the surrounding landscape. The building employs a series of passive and active systems aimed at enhancing energy efficiency. Key features include solar panels, rainwater collection systems, and greywater recycling, enabling the house to operate off-grid and reducing reliance on conventional utilities.

Design Characteristics and Innovations

The primary design approach involves the use of robust materials such as adobe and concrete, offering durability and thermal regulation. These materials serve not only structural purposes but also contribute to the building's overall energy efficiency. Large, strategically placed windows promote natural ventilation and daylighting, essential in desert climates. The design incorporates shading elements to minimize heat gain while maximizing the views of the natural landscape.

The spatial organization of the (H)OFF-GRID house features distinct public and private areas spread across three levels. The ground floor includes communal zones, a greenhouse for indoor horticulture, and areas designed for social interaction. The upper levels are dedicated to private quarters, allowing residents to retreat from communal activity. A flexible third level can adapt to changing family needs, showcasing the project's commitment to longevity and adaptability.

Furthermore, the inclusion of a passive cooling system utilizing a tower ventilation approach enhances indoor air quality while reducing energy consumption. Subterranean air tubes bring in fresh air pre-cooled through contact with the earth, aiding in temperature moderation.

Sustainability Strategies and Functional Integration

The integration of sustainable practices extends to water management, with systems in place for capturing and reusing greywater from household activities. This minimizes water waste and promotes responsible usage of resources. The reliance on local vegetation for landscaping not only beautifies the project but also bolsters the ecosystem and enhances biodiversity.

In summary, the (H)OFF-GRID house sets itself apart through its focus on long-term sustainability, innovative design solutions, and a seamless interaction with the environment. This project exemplifies how architecture can address contemporary issues related to climate and resource management.

Design a new small-scale home concept in the 10th edition of MICROHOME — 100,000 € prize + construction

Competition organisers

The 10th edition of the MICROHOME architecture competition invites architects and designers from around the world to explore the possibilities of compact, sustainable living. Hosted by Buildner in collaboration with Kingspan and Hapi Homes, this special edition challenges participants to design an off-grid, modular microhome for a young professional couple, with a maximum floor area of 25 m². Designs should prioritize innovation, efficiency, and real-world feasibility. 

A total prize fund of 100,000 € will be awarded, including three main prizes, the Kingspan Award, and the Hapi Homes Award, which will grant 15,000 € and lead to the construction of the selected design. The final registration deadline is September 25, 2025, and winners will be announced on Decebmer 9, 2025. For full competition details and submission guidelines, visit microhome.info.
