HEAT4COOL Budapest
Design and realization of a heat pump based Thermowatt system that would use communal wastewater to heat and cool buildings around the St. Stephan Square in Budapest District 4. Humid climate, annual average temperature 11.2 °C. The expected wastewater temperature is 15-20°C and the available wastewater flow is about 250 m3/hour.
+CityxChange Trondheim
Trondheim has seen many successes in the +CityxChange project, due to the effective collaboration between a series of partners in a range of sectors where new working methodologies have been pioneered to collaborate across fields. The municipality has taken on the role of an active coordinator and facilitator, striving to make real physical changes in the city.

+CityxChange Limerick
Through the +CityxChange project Limerick has worked hard to gain significant knowledge and understanding of the conditions to support the creation of PEDs. Working with many stakeholders to overcome obstacles, PED development is being advanced in the city through various initiatives such as the Pilot Retrofitting Grant Scheme aimed at retrofitting historic buildings.
Key outcomes and achievements in Limerick:
CELSIUS Site Cologne
In large cities such as Cologne, heat generation accounts for more than two-thirds of stationary energy consumption. This is why it is necessary to consider ways to make more efficient use of non-fossil energy sources and create more sustainable heating systems in metropolitan areas. One idea is to recover heat from wastewater systems that is currently simply flushed away.
