Exploits solar energy – a force of nature

Aage Nielsen claims that, during their cooperation on this project, the parties effectively adapted the LivingBetter concept and made it ideal for hotel operations. The solution ensures that fresh air is conditioned as it passes through the ventilation windows’ double-glazing panels and thermostatic control system. The partnership installed ventilation windows in every guest room and several other functional rooms at the hotel. The solution exploits natural solar energy to the extent that the ventilation windows add significant energy and are an integral part of the indoor climate solution. Moreover, heat emanating from the hotel guests staying in the room is recovered to heat water and the rooms on demand.

Danish IKM A/S supplies the exhaust air heat pumps. These are installed in the basement along with other plumbing and heating installations. Exhaust air is extracted from the hotel bathrooms. The heat pump fans create air exchange and exploit energy in the exhaust air to provide hot water and heating. This highly effective ventilation solution is achieved using only one exhaust air duct instead of the conventional two.

Space for more double rooms

When it became clear that intake ducts were not required, there was more space available in the building. Construction costs were cheaper. Running costs are now also lower than projected. The extra space has been used to create one extra double room on each floor – and therefore increased hotel income.

The developer then expressed a desire to incorporate lessons learned from the first new hotel at Tårnby to the GO HOTEL CITY project on Lergravsvej in Central Copenhagen. GO HOTEL CITY is under renovation. Here too, ventilation windows supply conditioned fresh air and IKMs exhaust air heat pumps ventilate and produce hot water. Less ventilation ducting simplifies the construction process and cuts both construction and running costs.
