Geothermal Greenhouse with ETFE and Glulam Structure for Community Engagement

Project in-detail

Combining a geothermal greenhouse with an ETFE and glulam structure, the facility enhances local agricultural practices while serving as a vibrant community center for education and engagement.
5 key facts about this project
01
Utilizes geothermal energy for greenhouse heating Incorporates ETFE for lightweight, recyclable roofing Constructed with FSC-certified glulam for sustainability Features a greywater recycling system for efficient water use Designed to facilitate local agriculture and community education.

The Myvatn Community Centre is located in Iceland and aims to meet the needs of the local community through a focus on sustainability. Serving as a gathering place for residents, the building incorporates features that promote environmental care and community engagement. The design follows the principles of cradle to cradle, emphasizing ways to reduce, reuse, remake, recover, and renew materials. This approach enhances both the building's function and the sense of community.

Site Planning and Layout

The layout of Myvatn Community Centre is organized for ease of access and functionality. It features a main entrance that leads into a welcoming reception area, where visitors can quickly orient themselves. The design includes various spaces tailored to community activities, such as places for meetings, learning, and socializing. This intentional arrangement encourages participation and connection among residents.

Sustainable Features

A key aspect of the centre is the greenhouse that uses geothermal energy for heating. This makes it possible to grow fresh produce, even in Iceland's cold climate. The greenhouse not only supports local agriculture but also serves as a learning tool for community members. A multi-functional room is incorporated into the design, allowing for a range of activities that stimulate social interaction and collaboration.

Material Selection

The choice of materials plays a significant role in ensuring the building's sustainability. Ethylene Tetrafluoroethylene (ETFE) is chosen for its lightweight nature and complete recyclability. Glued Laminated Timber (glulam) comes from FSC-certified sources, reinforcing responsible forestry practices. Concrete with volcanic ash is used for its durability and local relevance, supporting both the structure and environmental goals.

Innovative Systems

The Myvatn Community Centre employs advanced systems to enhance efficiency. A high-performance HVAC system improves energy use throughout the facility, while a greywater recycling system manages water resources effectively. Insulation made from Icelandic sheep wool also contributes to energy efficiency and supports local industry. Together, these elements create a practical and enduring resource for the community.

The entrance features a large glass façade that allows ample natural light to flow in, creating a bright atmosphere that connects the interior spaces with the beautiful landscape outside.
