Normally, the hotel is constructed in winter out of ice cut from a the Torne Riverand then left to melt as the temperatures outside turn to spring.
The new hotel will built from river ice just like its sister, but will use solar-powered refrigeration to keep the frozen walls from melting.
"...we'll be able to produce roughly 75 kilowatts from April to September, which gives us an energy surplus that we can use to run our existing buildings, like our restaurants, offices and warm rooms," said founder Yngve Bergqvist in a press release.

Nine luxury suites, each with a sauna and bathroom, will accommodate guests brave enough to strip naked in freezing temperatures. An ice bar will serve chilled champagne and an ice gallery will present works of art.
Guests will be able to take year-round advantage of local activities, including dogsledding, watching the northern lights or taking a boat trip on the river — all beneath the light of the midnight sun.
