Green Solution House

A bright idea based on sustainability

Green Solution House is a conference centre and hotel based on sustainable ideas and Cradle to Cradle principles. Situated on the island of Bornholm, Denmark, the centre opened to the public in 2015, following a comprehensive renovation project that included the construction of four large expansions with innovative meeting facilities and auditoriums.

To ensure plenty of daylight and ventilation, a selection of VELUX ridgelight solutions were installed in the expansion, atrium and reception area. To underpin the sustainability principles some of the VELUX Modular Skylight modules are with built-in photovoltaic cells. Photovoltaic modules are designed to generate free electricity to the building and its users, creating a valuable supplement to the consumption of conventional power. Also, a large number of single VELUX roof windows and domes were introduced to ensure a pleasant indoor environment, mainly in hotel rooms, hallways and conference rooms.
