Global District Energy Climate Awards celebrate world's leading sustainable district energy solutions 

In cooperation with the International Energy Agency (IEA) and their Technology Collaboration Programme on District Heating and Cooling, the UN environment cities initiative and the representative organizations of the district energy sector the winners of the 7th Global District Energy Climate Awards were revealed during the virtual awards ceremony on November 11, 2021.

Southern European hospitals have high cooling and heating needs during the whole year. Combined district heating and cooling networks are, therefore, an interesting application.

Waste water management systems exist in every city and could be exploited to heat buildings. They promise major heat recovery potential. The temperature of waste water ranges from 10 to 15°C on average, and can go even up to 20°C during summertime. This guarantees an adequate heat source for the operation of heat pumps throughout the whole year.

In Høje-Taastrup (Copenhagen) a project is established that will innovate, demonstrate, evaluate and disseminate technological solutions needed to exploit and use sources of very low-grade "waste" heat for heating of energy efficient buildings via Low Temperature District Heating (LTDH) and show how the District Heating (DH) systems can be more resource efficient and more energy efficient.
