COOL DH Workshop - The pioneer of Low-Temperature District Heating

COOLDH - Cool ways of using low grade Heat Sources from
Cooling and Surplus Heat for heating of Energy Efficient Buildings with new Low Temperature
District Heating (LTDH) Solutions.

COOL DH Workshop - The pioneer of Low-Temperature District Heating

The objective of COOL DH action is to support cities in their endeavor to plan and deploy new, efficient district heating and cooling (DHC) systems and extend, refurbish existing ones to higher standards. Thus allowing greater uptake of renewables, recovering of excess heat or cold while improving the overall efficiency of the systems.

One year has past, it's time for the first European Technical Workshop to discuss about the COOL DH innovations and results. The workshop will gather researchers, policy makers, public authorities and utilities. All together to debate about the future of District Heating, the use of surplus heat and local resources for low-temperature networks. 

The workshop will focus both on technical and non-technical topics concerning the COOL DH innovations and frontrunner demo sites (i.e. Europe's largest LTDH network in Lund)  making comparisons with other sister initiatives (such as the TEMPO Project)  and sharing experiences and best practices.
