The sun sends the earth 174,000 terawatts of free energy – every day.
It makes sense to use this gift of nature to heat and cool our homes.
The Willis building was realized by Belcotec as an innovation center for its own use. “We named it in honor of the inventor of air-conditioning, Willis Carrier”, explained Jan Vangeel, CEO at Belcotec, and added: “We wanted to make a statement with our own building. The energy level is 28, which is very low for office buildings.
After carefully examining all available options, the homeowner decided on Thermia. The system proposed by Atlas Trading was based on the Thermia Diplomat Optimum G3 8kW ground-source heat pump with passive cooling module and met all the project requirements.
The Aletschspa is heated by two inverter-driven Thermia Mega ground-source heat pumps with a heating capacity of 14-59 kW. Ground water with a temperature of around 10°C is the energy source for the heat pump. The heating system covers floor heating as well as pool and floatation pool heating. Cooling (air-conditioning) is provided by passive cooling, which means that energy to cool the facilities comes from the ground water.
The hotel and spa are heated by Thermia ground-source heat pumps. 18 Robust heat pumps with a total capacity of 715 kW provide heating, cooling and hot water to 24,000 m2 of hotel rooms, the spa, offices, shops and apartments.
When the Carlsson family moved in to their new home, they were using an oil-fired boiler and a pellet stove to heat the house. The boiler was approaching the end of its working life and the pellet stove required a lot of attention.
Energy consumption for heating purposes dropped to 2847 kWh and the heat delivered to the house was 9373 kWh, so 70 % comes from thin air and is renewable energy. CO2 emissions, originally 4 240 kg dropped to 2 070 kg, this is a massive 51 % reduction (2,170 kg CO2).
“The Willis building is more than just an office: it is an open area with different types of workspaces, creating an atmosphere that inspires innovation. Multi-functional, comfortable, bright and adaptable are the key words to describe its design.” - Charlotte Ooms, Architect, Archiles Architecten
“…we ultimately succeeded in satisfying the homeowner and providing all the requested functions. Moreover, when we measured the SPF again three years later, it was 4.17 – the perfect result.” – Yasin Jodeh, Technical Manager, Atlas Trading d.o.o.
“Thanks to Thermia’s modern and efficient geothermal energy system, the new Aletschspa can entertain its guests in the knowledge that they are caring for the environment and saving money.” Milos Bill, Managing Director, eta Group
24,000 m2 of hotel rooms, spa, offices, shops and apartments heated by Thermia heat pumps.
"…we wanted to simplify our daily life. That is why we wanted to have a heating system that would take care of itself as much as possible. And we don’t need to do anything with our heat pump…" Mattias Carlsson
True performance, measured day by day speaks for itself
