Concrete Shelters Surrounded By Natural Light With Geothermal Heating

Project in-detail

Designed to leverage geothermal energy, the Visitors Center is primarily situated underground, integrating concrete protection and light wells to create a welcoming educational space that reveals panoramic views of the surrounding volcano and lava fields.
5 key facts about this project
01
Utilizes geothermal energy systems for heating and electricity.
02
Designed primarily underground to minimize visual impact on the landscape.
03
Features light wells that enhance natural lighting in interior spaces.
04
Pathways reveal dramatic views of the surrounding volcano and lava fields.
05
Incorporates concrete protection for durability against extreme conditions.

The Visitors Center is located in a dramatic landscape marked by volcanic formations. Its design aims to provide a space for education and engagement with the surrounding natural environment. With much of the center placed underground, it minimizes visual impact and allows for deeper immersion into the unique geological features of the area. The architecture emphasizes interaction with nature through thoughtful pathways and viewpoints, creating an experience for visitors that is both informative and engaging.

Accessibility and Layout

The design prioritizes easy access to important areas, such as the new car park and drop-off points, guiding visitors to the reception and information desk. Underground pathways connect these spaces, allowing for smooth movement throughout the center. As individuals navigate these routes, they are introduced to expansive views of the volcano and lava fields. This gradual reveal draws visitors into the landscape, enhancing their experience as they make their way through the facility.

Natural Light and Atmosphere

Light wells and ETFE-covered pathways play a crucial role in the design, establishing a connection between the interior and the outside world. These features allow natural light to enter the building, brightening the spaces and creating a welcoming atmosphere. The changing quality of light throughout the day contributes to the interior ambiance, emphasizing the relationship between the space and its geological context. Visitors can appreciate the subtle play of light and shadow as they move through the center.

Material Selection and Sustainability

Materials have been chosen to support the overall function and sustainability of the center. The exterior incorporates concrete protection boards, rigid insulation, and waterproofing, which provide necessary protection from the elements and contribute to energy efficiency. A reinforced concrete roof is vital for structural stability. These selections not only fulfill practical requirements but also align with the center's commitment to environmental responsibility.

The approach to energy systems further illustrates the focus on sustainability. Geothermal solutions and independent electric power options reduce environmental impact and enhance the center's efficiency. The careful arrangement of space and attention to design detail culminate in a rich experience that invites visitors to connect with the natural landscape surrounding the Visitors Center.
