EUROPE
it ’ s important to give back to the community and make full use of the excess energy we produce .
“ Half of the neighbouring urban city ’ s needs can be fulfilled by our excess heat which is environmentally very impressive , yet this isn ’ t just about sustainability as there ’ s also a very solid business case behind it ,” he adds . “ Therefore , I think it ’ s important to show the industry that this is doable and to encourage others to follow our lead .”
Working alongside local Finnish energy company Nivos OY , the Russian web firm has developed a ground-breaking approach to heat production .
The excess heat from Yandex ’ s data centre is collected and directed through the district heating network to Mäntsälä households .
In doing so , the Finnish city has been able to reduce the price of heating and slash its emissions by 40 %.

The Mäntsälä data centre is built around an inherent need to drive efficiencies and its state-of-the-art district heating solution is a solid reflection of this ethos .
“ At the moment , our energy reuse factor is 0.31 , which means that 31 % of the energy what we take in can be recycled for further use ,” notes Kurvi . “ We are now embarking on the next phase of this energy reuse installation and through that , we hope to increase our energy reuse factor to
