The Technological University Dublin has become one of the first building of a new district heating system linked to an Amazon warehouse. Indeed, the excess heat produced by the data centre has been recovered for reuse and has become an unusual form of green energy.

It is estimated that this type of heat recovery and reuse saves 1,400 tons of CO2 emissions every year. This equals to a reduction of about 60 percent compared to the previous system of individual on-site boilers. Once fully operational, the district heating system will heat 47,000 square meters of local public buildings, 3,000 square meters of commercial buildings, and 135 apartments.
