The COOL DH-project is now closing its innovation process phase, which focused on different installation solutions for consumers, the distribution side and the production side. Some of the main findings were presented on the webinar in December that you can find on the following link: www.cooldh.eu/events/cool-dh-webinar/. All reports either are or will be published on the website: (http://www.cooldh.eu/reports/).

We have now entered a new phase in the project. The focus is shifting from innovation to demonstration of integrated smart city LTDH system solutions in Lund and in Høje-Taastrup. We invite you to keep following the project and hope to inspire new district heating solutions for sustainable and smart cities.

Status of the demo sites

Brunnshög

The construction of Xplorion, a multi-family house with focus on sustainability, has begun. Xplorion is LKF’s, the municipal housing company of Lund, greatest investment in sustainable living so far. It will use LTDH, live up to the requirements in the passive house standard, be car free, have an electrical car and bike pool, use locally produced electricity with solar panels etc.

Visualisation of Xplorion

LKF’s Xplorion is a multi-family house with rental apartments that focuses on sustainable living.

Looking closer at the LTDH-network, the main pipe to MAX IV will be built the second quarter of 2019. The first costumer will connect in the third quarter of 2019 with plastic pipes. The greater expansion of the plastic grid will start at the end of 2019 or beginning of 2020.

Østerby

Logstor have developed new high-pressure polymer flex-pipes and installation in Østerby will start in April/May. In the first part of 2019 successful meetings with the tenants were held.

Management from the City2 Mall have positively evaluated a combined offer from Høje Taastrup Fjernvarme to implement a new combined district heating/cooling heat pump and new heat centrals owned/maintained by Høje Taastrup Fjernvarme. The contracts are yet to be signed. The legal framework has been clarified – but there is still some work left on how the heat pump-installation can optimally use the surplus electricity from the large PV-installation owned by the Mall.

The design of the new Town Hall in Høje-Taastrup has started and will be supplied with district cooling and low temperature district heating that is developed in COOL DH. The design of the energy system is now at work.

A kindergarten in the Østerby area, owned by the municipality, considers the possibility to connect to the new LTDH-system, as well as a special legionella treatment of the domestic hot water. The internal heat distribution system is investigated in order to suggest required improvements.
