As Europe swelters in a heatwave, residents probably don’t want to hear about ways to make their homes even hotter, but that’s what Polish property developer Citylink is talking about, with plans to dump waste heat from a new data center in Wrocław into the municipal district heating network. Citylink is designing the data centre so that heat from servers can be recovered instead of being dissipated via cooling systems — and as the data centre grows, any increase in computing power will mean more energy available for recovery. The collaboration with local power company Kogeneracja will provide “valuable experience in designing and operating modern data centres, with a particular focus on infrastructure dedicated to AI nodes,” said Michał Starybrat, development director at Citylink.
