Energy efficiency in our modern data center Pieni Paja in Helsinki, Finland, is guaranteed by cooperating with Finnish energy producer Helen.

The cooling and air conditioning systems in the premises are integrated so that condensate heat is recovered as efficiently as possible into Helen’s district cooling network. The basis for Pieni Paja’s design was a PUE value of less than 1.2. The PUE value describes the power usage effectiveness of data centers. All electricity used at the data center is sourced from renewable energy sources.

“IT equipment and their cooling use the most energy in the data centers. Optimizing cooling can significantly improve energy efficiency. Pieni Paja uses a sectional cooling system in which all heat generated from production is recycled. Pieni Paja is designed in an energy efficient and environmentally friendly way,” says Juha Syrjänen, Director, Digita Data Centers.

“The utilization of waste heat from data centers is a key part of Helen’s transformation towards a sustainable energy system where energy is generated from multiple sources. We enable carbon-neutral cooling for data centers and the recycling of waste heat on our energy platform. This way, data centers support our goal of being carbon neutral by 2030,” says Henrietta Lahti, Business Lead for data centers and waste heat recovery systems at Helen.

For Digita, fostering the wellbeing of our shared environment is a priority. We are improving our operations actively and sustainably to minimize our adverse environmental impact and carbon footprint. Digita aims to be carbon neutral by 2030.
