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

About Cool DH

The COOL DH project ended in September 2022. The objective of COOL DH was 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.

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.

Høje Taastrup Municipality  has decided to go fossil free and to transform present natural gas heated areas to district heating (low temperature) and heat pumps. COOL DH is included in theese plans and have contributed to the transformation.…

What does the users think about Low Temperature District Heating?

, , , ,
User acceptance is an important part for low temperature district heating to be installed and used. Especially since it is often sold with arguments such as benefits for the customers, not only the environment. But do the customers really care?…
