Subscribers only
Incorporating geothermal heating and sunlight-responsive paneling, the facility harmonizes with the volcanic landscape while providing a versatile space for visitors to relax and learn.
5 key facts about this project
01
Integrates geothermal energy for heating through radiant floor systems.
02
Facade panels represent monthly sunlight variations, enhancing visual interest.
03
Panelized construction allows for efficient offsite fabrication and assembly.
04
Large operable skylights promote natural ventilation and daylight.
05
Designed as a multifunctional space for relaxation and education for visitors.

The Iceland Volcano Coffee Shop is located in a landscape shaped by volcanic features. Designed to be a gathering place, it serves visitors before and after their adventures to the nearby volcano. The overall design concept focuses on sustainability and energy efficiency, creating a warm and inviting atmosphere that encourages relaxation and social interaction.

Panelization and Layout

The building employs a panelization system, allowing for offsite fabrication of walls and roofs. This strategy improves construction efficiency and enables quick assembly on location. The layout includes exhibition spaces, lecture areas, and a coffee shop, making it a multifunctional environment. Large restrooms and sufficient office spaces contribute to the building’s usability and enhance the visitor experience.

Sustainable Energy Strategies

Sustainability is a key focus of the design. Geothermal energy is used for heating through radiant floor systems, showcasing a commitment to local energy sources while reducing the impact on the environment. This choice aligns well with the building’s ecological context, ensuring efficient operation and comfort for all occupants.

Light and Facade Design

Natural light enhances the indoor environment, as large skylights and extensive glazing allow sunlight to fill the space. This reduces the need for artificial lighting, creating a brighter, more welcoming atmosphere. The facade reflects changes in sunlight throughout the year. Each panel corresponds to the monthly variations in solar exposure, with narrow glass openings providing visual interest and connection to the outside.

Materials and Context

The exterior incorporates high-performance precast concrete, selected for its strength and durability. This choice of material connects the building to the surrounding landscape, as it utilizes resources found locally. The thoughtful use of concrete reinforces the relationship between the structure and its environment, merging the natural characteristics of the site with practical building needs.
