On the roof, there are 300 square metres of solar collectors that provide hot water for the building. Each floor is equipped with two decentralised ventilation systems connected to the hotel's booking system, enabling the system to easily prioritise the occupied areas of the hotel. The windows are designed in a way that minimises the window area while maintaining views and lighting. In addition, the hotel is designed with thermal shafts running through the building that reduce air resistance and help air flow more freely throughout the construction. The hotel has an estimated energy consumption of 50 kWh per square metre per year. In comparison, a hotel with an energy class A rating consumes 135 kWh per square metre per year. Furthermore, the choice of materials is locally sourced, with most of it coming from the Trøndelag region.
