In Copenhagen around 4 000 hotels out of 21 000 receive a special type of district cooling that offers the hotels a more sustainable and cheaper alternative to regular air conditioning. The largest hotel chain in Copenhagen, Arp-Hansen, as well as Denmark's biggest hotel chain Scandic both receive the sustainable air condition alternative at several of their hotels.

Nina Maria Klok, communication advisor for water supplier HOFOR informs Standby.dk that they have a total of 18 hotels as customers. "Most of our customers are from  Arp-Hansen and Scandic, but also Copenhagen's newest 5-star hotel, Herman K, gets environmentally friendly remote cooling from us - as does one of the  newest boutique hotels in Copenhagen, Hotel Sanders," says Nina Maria Klok.

Remote cooling technology is similar to district heating and it is environmentally friendly as it does not emit very much CO2, mostly only power is needed to pump water, HOFOR informs.
