Geothermal Heating Integration With Basalt Façade and Green Roofing For Seasonal Recreation

Project in-detail

Employing a basalt façade and an integrated geothermal heating system, the structure uniquely harmonizes with the Mývatn landscape while providing a multifunctional hub for seasonal recreation.
5 key facts about this project
01
The structure utilizes local basalt stone, ensuring continuity with the surrounding geological features.
02
Cross-laminated timber panels form the roof, enhancing thermal performance and structural integrity.
03
A green roof is integrated to promote biodiversity and minimize visual impact on the landscape.
04
The design enables passive solar heating through strategically positioned large glass elements.
05
Interactive exhibits within the space educate visitors about the region's geology and ecology.
The Sundial architectural project is situated in the Mývatn region of Iceland, designed to engage users with the surrounding natural landscape while facilitating various seasonal activities. The structure draws inspiration from traditional sundials, embodying a relationship with time, light, and environment. Its circular form serves as a focal point for visitors, providing spaces that reflect both functionality and an awareness of the regional climatic conditions. The project integrates seamlessly with the geothermal features of the site, employing sustainable architecture principles to minimize its ecological footprint while maximizing user experience.

Innovative Material Use
The design utilizes local basalt stone for the façade, establishing a visual connection with the geological context of Mývatn. This choice not only enhances the aesthetic appeal but also provides structural durability. A prefabricated wooden roof offers warmth and complements the stone’s ruggedness, while large glass panels facilitate natural light infiltration, promoting an inviting atmosphere. The introduction of a green roof further supports biodiversity and ensures the structure remains unobtrusive within its environment.

Functional Design and Interactivity
The interior space planning prioritizes functionality across seasonal activities. Defined zones accommodate relaxation, changing facilities, and visitor engagement areas, all designed to inform users about the local ecology and geological features. The architecture supports a natural flow between public and private spaces, encouraging user interaction with both the building and the surrounding landscape. Unique to this project are its features aimed at enhancing visitor experience through direct engagement with nature, including visually accessible geothermal elements and views of the Mývatn area.

Structural Responses to Environment
The architectural design prioritizes sustainability, implementing an underfloor geothermal heating system to address Iceland's cold climate efficiently. The streamlined form of the building, combined with careful attention to airflow and light penetration, reflects a comprehensive approach to environmental design. By creating spaces that respond to both the weather and the geology, the Sundial becomes more than a static structure; it is a dynamic element within the landscape that changes with the seasons.

For further insights into this architectural endeavor, readers are encouraged to explore the project presentation. Detailed architectural plans, sections, and design ideas provide a comprehensive understanding of how the Sundial harmonizes with its natural setting and serves its intended functions effectively.
