The renovation and expansionof this 4,500m2 hotel and conference center on the Danish island of Bornholmsupports a positive, healthy footprint and aspires to eliminate the concept of waste by applying 75 sustainable solutionsacross all aspects of the project, from building materials and systems to energygeneration and monitoring.
GXN and our client designed the Green Solution House to evolve andimprove over time. All products andtechnologies are, in principle, replaceable with their more sustainablecounterparts thought the life of the building.

Circular sustainability:
At Green Solution House we want to inspire our visitors by offering a comfortable stay in a healthy and creative environment.
The building and landscape show a holistic approach to sustainable design, emphasising regenerative solutions including healthy indoor climate, renewable energy sources, active materials and recyclability.
At Green Solution House we try out, demonstrate and continuously revisit our green solutions. We believe that iteration creates understanding and leads to innovation. We seek to exchange knowledge with local and global communities to inspire a sustainable future. Our mission is to explore circular sustainability.
Hereby we redefine revenue
Architectural description
When we approach the building, we encounter a large covered porch between the two existing Buildings A and H. Here we can already sense the bright foyer, which is embraced by daylight due to the large roof made by modules in glass with PVs. When we enter the building, the reception area is located to the right in building A, and to the left we can sense the bright restaurant area in building H. Immediately from the foyer, we can see all the way out to the countryside through the conference hall – and the view invites the visitors to explore the building and the nature surrounding the Green Solution House.
The foyer is unheated, but in large parts of the year, especially in spring and autumn the area will be well-tempered – and during summertime the visitors will have a feeling of Southern Europe evenings. All year around the guests will have the opportunity to experience the weather from all sides, without being outdoor.
The conference hall is an extension of the lobby centered with large double doors as entrances. An interior green facade let our gaze wander up to the gallery where the two existing hotel wings A and H are available.
The conference hall is centered in the two middle range segments of the new building. The western part of the segment encloses three meeting rooms as well as a technician room and storage. The meeting rooms are flexible in the entire segment and can be combined with the conference hall. The eastern range segment invite into a another unheated climate zone as glass house leaves an experience Bornholm's climate and weather in a special
way - close, but in the shelter. This creates room for many activities and opportunities, exhibitions, project work, meetings, training. Towards the landscape all four segments og the building opens up, and gives a feeling of being part of the landscape.
The materials used in the new building is clear and bright, with air cleaning carpets in the conference area and tiles in the foyer in a dark color that can absorb heat from the sun throughout the day in order to keep the room
temperate in the transition periods.
Light treated walls and acoustic ceilings in the conference section lets the wood structure dominate the room.
If you had to do it again?
One big learning from the project - my very first buildingproject - is that the building industry in general is not very innovative, and there is a huge communication gap between the different partners. To say it short: Architects have no respect of engineers, architects and engineers have no respect of the contractor and none of them listens to the investor/owner. In general everybody wants to do it there way, and to make money they turn to "copy and paste" eventhough the owner wants to be innovative - simply because the incentive structure in the building industry is based on "fast in fast out". 90% of my time has been used on communication trying to get people to work together, to create momentum and "translate" the differenct language each partner uses. My buildings are 1. generations. The money I earn on operating the hotel will be reinvested to create 2.nd generation of the building with new materials and solutions. The buildings will never stop changing. Next time - I will work together with smaller companies when I choose advisors - especially the engineers - I rather be a big customer in a small company, than a small one in a big company.
Building users opinion
The delegates at conferences in our new conferencefacilities say: Because the indoor climate is so wonderfull and there are so much daylight we feel fresh even after a long day of plenty slideshows.

Pyrolisis Plant

Servizi esterni / Raccolta e trattamento dei rifiuti
At Green Solution House we produce energy from food leftovers. All food scraps and organic material from the main building is fed into our own stationary pyrolysis plant, that likes all carbon based waste. The material is first dried and ground, then all the oxygen is removed. The pyrolysis process heats the waste, breaks it down, and then produces natural gas and char. A cyclone separates the gas, producing biochar, that sequesters carbon in a stable state. Biochar is valuable as an additive for the gardens as it improves soil health and water retention. The gas is combusted in a Combined Heat and Power (CHP) engine generating heat and electricity to be used in the building. Excess hot water is stored onsite in a swimming pool, repurposed as an energy storage system. The pyrolysis plant is self-supporting, and only requires a small amount of energy to start up.
Green Solution House will release approximately 12.4 tons of dry material to the Pyrolysis Plant yearly. The plant has the capacity to process 1 ton of dry material over 6 hours which produces an output of 180 m3 of gas, 360 kWh of ectricity, and 100 kg of biochar.
