Spherical Volumes with Vacuum Glazing Enhancing Visitor Experience in a Harsh Climate

Project in-detail

Spherical volumes constructed with vacuum glazing create a warm and inviting space that enhances the visitor experience while offering refuge from harsh Icelandic weather.
5 key facts about this project
01
Spherical design optimizes volume-to-surface area ratio for energy efficiency.
02
Uses vacuum glazing to reduce heat loss while maximizing natural light.
03
Incorporates a layout with distinct zones for coffee, exhibitions, and visitor services.
04
Constructed with sandwich panels featuring stainless steel and mineral wool insulation.
05
Large glass panels enhance views of the surrounding Icelandic landscape.

The Iceland Volcano Coffee Shop is located near Hverfjall in Iceland, designed to provide comfort and warmth for visitors in a challenging climate. It serves as a welcoming space for tourists exploring the natural landscape. The building's design concept centers around the use of spherical shapes that allow for maximum interior space while effectively minimizing heat loss, making it both functional and visually appealing.

Design Concept

The building features spherical forms that enhance energy efficiency and create inviting spaces. By focusing on thermal performance, the design ensures that visitors can experience the beauty of nature while enjoying a comfortable environment. This thoughtful approach reflects an understanding of both the local climate and the needs of those who come to admire it.

Materials and Thermal Performance

Materials chosen for the construction include vacuum glazing and sandwich panels. The vacuum glazing offers a heat loss coefficient of 0.7 W/m.K, which helps maintain a stable indoor temperature while allowing natural light to enter. The sandwich panels provide robust insulation with a heat loss coefficient of 6.0 W/m.K, comprising stainless steel and mineral wool to withstand harsh weather. This careful selection of materials contributes significantly to the building's overall performance.

Spatial Organization

The layout is designed for ease of movement and accessibility, incorporating a coffee shop, exhibition zone, toilets, a visitor center, and office spaces. Each area is strategically placed to enhance the visitor experience. Large glass panels connect the indoor spaces with the surrounding landscape, drawing the outside in and allowing visitors to engage with nature directly.

Stunning Views

Interior spaces are characterized by expansive views of the Icelandic landscape, which enhance the experience of all who visit. This design feature creates a sense of immersion in the natural setting, reminding visitors of the beauty that lies just beyond the walls. Such thoughtful details help establish the coffee shop as a place of respite and reflection in an extraordinary environment.
