Waste heat is recovered at DNA's Rauma office and used in the Minerva Medical Centre next door. Servers that are located in DNA's equipment facilities require significant cooling, and with the help of new cooperation, waste heat is used in the medical centre nearby. Significant savings are achieved through cooperation in the heating costs of the hospital, and electricity is also saved in DNA's office.
Critical servers are located at the equipment facilities in Rauma that produce DNA's entertainment, corporate and consumer services.
Servers require significant cooling, and waste heat is now used as this heating and use water for radiators at the Minerva Medical Centre.
How did this idea come about, DNA's Vesa Raikisto from Rauma?
”Our landlord in Rauma changed, and the new owner of the property decided to carry out a complete renovation. In this connection, heat recovery was discussed and the possibility of using waste heat from DNA's equipment facilities.”
The technical solution was easy to implement but the challenge was to find suitable routes in an old property that is filled with cables.
The arrangement benefits both parties. With the help of the procedure, there is an annual reduction of 19.4 per cent in emissions and operating costs in Minerva's heating. The recovery of heating in DNA's property reduces the temperature of the coolant at the equipment facilities and thus directly reduces the energy required for cooling. Similarly, the carbon dioxide emissions of the property were reduced by several tens of tons per year due to the renovation.
“The pigeons were probably the only ones who were disappointed in the matter as they had been able to enjoy the heat from ventilated air during cold weather,” says Raikisto with amusement.
Early this year, the Carbon Neutral Municipalities project (HINKU) of the Finnish Environment Institute awarded the innovative carbon neutral solution of Minerva Medical Centre and DNA’s Rauma office as the best emission reduction method of the month.
