Nowhere in Denmark does the sun rise earlier than on Bornholm – and the Baltic Sea island would also like to be the first part of the country that meets its energy needs from completely carbon-neutral renewable sources. The ‘Green Solution House’ in the south of the island's main town, Rønne, is a lighthouse project for this turnaround. The former Hotel Ryttergården from 1973 has been renovated, supplemented with a congress centre and equipped with numerous forward-looking solutions from the fields of architecture and building technology. Three sustainability concepts were at the centre of the building design: DGNB certification, the cradle-to-cradle principle aimed at a circular flow economy, and the Active House Standard, which focusses on a healthy indoor climate and an excellent supply of daylight.
The results of this strategy are apparent to visitors everywhere they go. In many places, recycled materials were used; there are carpets that clean the air and a small bioreactor in which algae are used to clean the hotel's waste water. Above all, however, daylight and the coastal landscape are omnipresent all round the inside of the building. The hotel rooms receive light through the flat roof windows and via the balconies, which have been fitted with new glass balustrades. Above the foyer, there is a folded glass roof composed of modular skylights, some of which are fitted with solar cells and thus contribute to the power supply. And thanks to large glass facades, the sunlight can exert its invigorating effect on listeners and speakers even in the conference rooms.
