Volcanic Ash Concrete and Thermal Mass Design in a Community Greenhouse and Multipurpose Hall

Project in-detail

Constructed with volcanic ash concrete and emphasizing passive design principles, the community greenhouse and multipurpose hall seamlessly integrate sustainable practices while fostering social interaction and engagement.
5 key facts about this project
01
Constructed primarily with volcanic ash concrete for durability and environmental relevance.
02
Incorporates passive solar design strategies to optimize energy efficiency and comfort.
03
Features an indoor greenhouse that supports local flora and enhances user engagement with nature.
04
Utilizes regional craftsmanship in the detailing of charred wooden shingles for weather resistance.
05
Designed with flexible multipurpose spaces to accommodate various community activities easily.
The architectural design project is a well-conceived facility that incorporates a multipurpose hall, restaurant, and greenhouse, strategically positioned within a landscape characterized by volcanic terrain. This project represents a fusion of modern architectural techniques with traditional materials, leveraging the unique environmental context to create functional and engaging spaces. The design emphasizes sustainability and adaptability, catering to various communal activities while enriching the local environment.

The multipurpose hall serves as a versatile venue suitable for events ranging from workshops to social gatherings. Its layout allows for flexible configurations, enabling different usages without substantial modifications. The adjoining restaurant not only provides dining options but also enhances visitor experiences with its expansive views of the surrounding landscape. The greenhouse plays a crucial role, linking the interior spaces with nature and facilitating the growth of local flora, thereby fostering a strong connection between the inhabitants and the environment.

Unique Material Applications
This project differentiates itself through its innovative use of volcanic materials such as ancient concrete, which is noted for its durability, sustainability, and compatibility with the surrounding landscape. The incorporation of locally sourced materials demonstrates a commitment to minimizing ecological impact while also honoring local heritage. The design utilizes wood extensively, providing warmth and contrast to the concrete, while aluminum roofing enhances the structure’s resilience against harsh weather conditions.

A distinctive feature of the project is its emphasis on open space and natural light. Generous glazing along the façades directs sunlight into the interior, promoting energy efficiency and reducing dependency on artificial lighting. The strategic orientation of these spaces not only optimizes natural lighting but also frames stunning views of the volcanic landscape, allowing occupants to engage with their surroundings.

Sustainable Design Techniques
Sustainability is at the core of the project’s architectural approach. By incorporating geothermal heating and efficient water collection systems, the design aims to minimize resource consumption. Automated lighting control systems further contribute to energy efficiency, adjusting illumination based on real-time environmental conditions. These thoughtful design strategies ensure that the building operates in harmony with its natural setting while providing a comfortable environment for users.
