The use of air conditioning systems powered by seawater is becoming very popular in Copenhagen especially by the hotels in the city making best use of it.
This environment friendly technology is being adopted very fast by the hotels. An increasing number of hotels in Danish capital Copenhagen are using innovative air conditioning systems powered by seawater to reduce CO2 emissions and trim energy consumption.
There has been high enthusiasm for such technology showing 112.5% jump as compared to 2018. One-third of Copenhagen’s Hotel Rooms are now cooled with Seawater. As of 2023, approximately 8500 hotel rooms in Copenhagen out of nearly 24000 have been equipped with this technology.
Seawater drawn from Copenhagen’s harbour is distributed to cool commercial and industrial buildings in the Danish capital through two district cooling facilities. After a property connects to the district cooling, it reduces CO2 emissions by up to 70% compared to using local end-of-life cooling systems.
In addition to Copenhagen’s hotels, several banks, museums, and department stores also use the attractive remote cooling solution.
“When a property connects to our district cooling, it reduces CO2 emissions by up to 70% compared to using local end-of-life cooling systems. Seawater requires less electricity, and the individual property can thus save up to 40% compared to local electricity-powered systems,” says Jakob Thanning, District Manager of Customer Solutions & District Cooling at HOFOR which is responsible for the water supply and wastewater disposal in eight municipalities in the Copenhagen metropolitan area.
Further district cooling allows better utilization of property’s space. Thanning elaborates on this by mentioning that the district cooling solution allows for more room on building facades and rooftops, as the system is contained underground. This is essential in a city like Copenhagen, as space is becoming increasingly scarce. Also in terms of accomodating the many tourists flocking to the Danish capital.
“The sustainable transformation of the capital’s tourism industry is a huge task. Most recently, we launched the sustainability manifesto for the tourism industry, Planet Copenhagen, which will create actions and provide solutions that contribute to more sustainable tourism in the capital. With focus on reducing CO2 emissions, district cooling of hotel rooms is a great example of the initiative pushing us in the right direction,” says Runa Sabroe, Development Director at Wonderful Copenhagen, the capital region’s official tourism organization.
Seawater is widely used for cooling in many areas of the world, particularly in the Mediterranean, Middle East, Latin America and Pacific regions.
