Scandinavia's first zero-energy hotel, Nationalarenan 3 in Arenastaden, is now in the final stages of completion. The building produces as much energy as it consumes, and has now achieved FEBY `Gold Plushus' certification. FEBY's purpose as an organisation is to increase and develop energy-efficient construction. Nationalarenan 3 is a unique project that aims to meet ambitious sustainability targets, while calling on the industry as a whole to build more sustainably. Some 25 geothermal energy boreholes along with a total of almost 2,500 sqm of solar panels on the facade and roof produce more energy than the property will consume. The south-facing facade and roof are both covered in solar panels, which generate enough energy in one year to power an electric car for more than 40 trips around the globe. This means the hotel has the most solar panels per square metre of any hotel in the world. The building has now been certified according to FEBY `Gold Plushus', and in order to achieve this certification the building was designed to keep heat loss at extremely low levels, as stipulated in the criteria for FEBY `Gold Plushus' environmental certification. The building is supplied with cooling and heating from heat pumps that efficiently load and collect energy from borehole stores. The 11-storey high building is made up of three sections: a hotel with 336 rooms, 88 long-stay apartments and an office, which will be the location of Nordic Choice Hotels' Swedish headquarters as of spring 2021. The hotel will also house restaurant and conference space and a lobby area. In addition to FEBY `Gold Plushus' status, the aim is for the project to also be certified to BREEAM Excellent standard.
