Data centres are known for the high volumes of energy they use to cool the ICT equipment stored in them. Reducing the amount of energy that cooling installations consume is a major focus. All of our Data Hotels feature innovative cooling solutions, such as free cooling. Because our installations are primarily put together by our own engineers, we know the optimal settings. Our track record shows that TCN Data Hotels achieve energy savings of up to 80% compared to conventional data centres.
Cooling the building itself - light outer surface
TCN places great emphasis on reducing the total energy consumption of its Data Hotels -- not only indoors, but also in the design, development and construction of the buildings themselves.
Data Hotel Groningen's roof, with its surface area of over 5,500 square metres, was transformed from black to white in 2011. The new, bright white, reflective outer surface serves to deflect outdoor heat. As a result, the interior doesn't require as much cooling because less heat enters the building.
According to a study by the Technical Inspections Organisation (TÜV), this change represents a temperature difference of 35 degrees compared with traditional roof covers, meaning that the Data Hotel is much more sustainable.
In 2007, Data Hotel Eemshaven was also fitted with a light roof cover. When this Data Hotel, with a roof surface area of 18,000 square metres, was developed in 2007, its light grey roof cover was state of the art. Partly because of the roof covers, the energy efficiency inside the TCN Data Hotels is among the best in Europe.
