Geothermal Heating and Hydroponic Cultivation in a Sustainable Greenhouse Eatery

Project in-detail

Utilizing geothermal heating and hydroponic cultivation, the structure serves as a sustainable greenhouse eatery that offers guests a unique dining experience intertwined with the cultivation of food in the stark beauty of Iceland's landscape.
5 key facts about this project
01
Utilizes geothermal energy for heating without greenhouse gas emissions.
02
Incorporates a closed water circuit system to recycle wastewater from plant growth.
03
Features an atrium ventilation design to maintain indoor air quality discreetly.
04
Integrates hydroponic cultivation to ensure year-round plant growth.
05
Positioned to enhance views of the Hvjerfall volcano and Lake Myvatn.

The Greenhouse Eatery at the Hill integrates restaurant functions within a greenhouse context, situated in the unique lunar landscape of northern Iceland. The design aims to connect with the environment, offering views of the Hvjerfall volcano and Lake Myvatn for its visitors. The concept merges culinary and botanical experiences, enabling guests to witness the growing process of the plants while they dine.

Design Concept

The structure serves as both a restaurant and a conservatory. This dual purpose enhances the dining experience and educates visitors about sustainable practices in food cultivation. The architecture focuses on energy efficiency and the use of local resources, providing a model for responsible design in challenging conditions.

Sustainability Measures

Energy sustainability is achieved through the use of Icelandic geothermal energy for heating, which helps reduce greenhouse gas emissions. The partially underground design takes advantage of thermal mass from the soil, acting as natural insulation that lowers energy consumption. These strategies showcase a dedication to sustainable practices throughout the building's design.

Water Management

Water management is an essential part of the design. Wastewater generated from the cultivation process is recycled, creating a closed water circuit that minimizes environmental impact. Additionally, the building collects melted snow from the heated roof, further enhancing its water efficiency during the harsh Icelandic winters.

Future Expansion Plans

Future plans look to expand the greenhouse areas, using the flat terrain of the hillside. This growth will preserve the views of both the Hvjerfall volcano and Lake Myvatn, ensuring that the new spaces remain connected to the landscape. This careful planning keeps the building in harmony with its surroundings, enhancing the original intent of the design.

Large glass panels allow sunlight to fill the interior, creating a bright and inviting atmosphere. The design reflects a thoughtful interaction between the building and its natural environment, encouraging visitors to enjoy both food and nature together.
