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.

Improved use of individual metering concepts

/
In COOL DH we have studied how to improve individual metering concepts and ways of using gathered data for billing district heating. In the report Improved use of individual metering concepts , we provide an overview of regulations on district heating metering and billing in Sweden and Denmark. It also provides an overview on applications to use on customer’s meter readings for energy efficiency improvements.

New design concepts for optimisation of LTDH distribution systems

/
In this report you will learn about the design process of a low-temperature district heating network, highlighting the design factors that lead to reduction of heat losses in the distribution pipes. To demonstrate the technology, two real-scale demonstration projects are described in Høje-Taastrup, Denmark and in Lund, Sweden. Emanuele Zilio, engineer at COWI A/S, gave a short interview to summarize the report
