COOL DH - a pioneering project for district heating solutions #cool_dh

About Cool DH

Cool DH explained in 4 minutes

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.

Demo sites

Brunnshög, Lund

The Brunnshög district is an ambitious project, with the goal to offer the best research and innovation environment in the world and to showcase sustainable urban development. Fully developed the district will have 40,000 inhabitants and employees before 2050. Low-grade surplus heat recovered from the research facilities of ESS and MAX IV will heat the entire district.

Østerby, Høje Taastrup

In 2015, the district heating supply consisted of 51 % fossil free energy from biomasses, the renewable part of waste, solar, geothermal energy etcetera. Using a larger share of low-grade surplus heat and increasing system efficiency is an important step of reducing emissions even more.

Solutions for local integration of renewable energy sources (RES)

/
This deliverable summarizes and gives an overview of existing and newly developed technical solutions used for the domestic hot water production that can be implemented in low temperature or ultra-low temperature district heating networks, and that can increase the share of renewable energy in the building sector.
