Smart Heating and Cooling in the EU
January 2017

European Commission Representative:
“An excellent and unique project”

Meet Szilvia Bozsoki, the Commission’s project officer responsible for CELSIUS. She has high hopes for the project and firmly believes that they will be fulfilled.

Ms Bozsoki, how do you find that CELSIUS is developing, related to EU expectations on projects like this?

CELSIUS is an excellent project but also quite unique among the Smart cities projects. The combination of the extended number of demonstrators with the strong commitment for replication and the special focus on DHC makes the project very special and difficult to compare.

Expectations are high as CELSIUS represents a major project for the heating and cooling sector with an ambitious replication commitment. Five EU cities are involved in the demonstrators with strong support from the municipalities and good balance between municipal, industrial and research partners."
What do you wish that CELSIUS should achieve before project completion, in order to meet your expectations?

"I'm convinced that the bar was set high immediately at the beginning of the project and the completion of the project deliverables and milestones without major deviations is not achieved without effort.
The project is on good track and I'm confident that it will achieve the goals set. CELSIUS collaboration with other EU funded projects is excellent and it is in the EU's interest that projects build on each other's results and avoid overlaps and duplications."
What qualities or achievements are needed for projects like this to create true impact?

"We need more than demonstrated innovative solutions in order to create impact. We need to bring innovations to the market, to the end users. The replicability of solutions and the tools to guide other cities or districts in their endeavour to create sustainable and efficient DHC is key, including a good communication and dissemination strategy."
What kind of legacy do you expect from CELSIUS, in terms of results that live on?

"CELSIUS already created a name in the DHC sector. From the innovation side, the first-in-the-world demonstrations in the project will certainly live on.

I expect that the best practices and the toolbox will be used by the extended network of interested cities even after the project lifetime if available.
The project also contributed to the EU heating and cooling policy work and this will still be in place after the project ends."


Experts on future of district heating

- Don’t miss tomorrow's webinar
CELSIUS offers you insight into 4th Generation District Heating. In a webinar, experts will present the latest news in cutting-edge technology, trends and challenges which influence the district energy of the future. 

Tomorrow, on January 18 at 10:30 CET, the webinar is opened by Anna Boss, Energy research engineer at RISE, Research Institutes of Sweden.
”I will give an introduction to the idea of 4th generation district heating: a developed DH concept aimed at sustainable energy systems. It uses more decentralised, renewable and recovered energy, distributed at lower temperatures. It includes smart control and higher integration with other energy systems like electricity. I will highlight benefits and point at new possibilities to fulfil end-user demands”, Anna Boss says.
Jonas Norrman, managing partner at IMCG, Innovation Management and Communication Group, will present the development of 2nd generation Internet of Things and how it affects the district energy market.
”The 4th generation district heating and cooling systems will be a part of the connected society, where Internet of Things plays a crucial role. It will reduce the investment cost for smart and sustainable energy systems in cities. It also enables the development of secure horizontal communication between different sectors, e.g. between your building and your electric car”, Jonas Norrman says.
Next comes Roberto Fedrizzi, coordinator of the sustainable heating & cooling research group at EURAC, partner in the FlexiNet project. He will present innovative solutions for future networks.
... And last but not least, Kristian Honoré, energy planner at Danish energy utility HOFOR, will give an illustration of how Copenhagen, a city with one of the most advanced district energy systems in the world, is adapting to future trends and challenges.
Join the webinar by following the instructions in the invitation previously sent by email.

Upcoming webinars

18 January:
CELSIUS Talk: 4th generation DH systems

25 January: 
CELSIUS Talk: Heating and cooling strategy development

14 February:
CELSIUS Talk: Social marketing

1 March:
CELSIUS City Talk: Dublin

Webinars are by invitation only and priority will be given to CELSIUS member cities.

These words were spoken by the Executive Director of Energy Cities, the European association of local authorities in energy transition. 

Claire Roumet took part in a panel debate on 'Efficient energy and smart cities' at the SET Plan – Central European Energy Conference in Bratislava in December.
The panel discussed the need for new innovations while also making sure that we use what we have. Roumet said there were many local treasures such as waste heat and energy, and she wished for a treasure map for cities to find them. 

An innovative workshop on future DHC

Join our two day workshop in Lyon on how cities can continue to innovate state-of-the-art district energy systems, adapt to future trends and challenges, and choose the right technologies to leap forward with smart and sustainable long-term strategies.

”The most exciting feature of this event is the collaboration between various actors at very different levels: public and private on a global, European, national and city level”, says Emilia Pisani, CELSIUS responsible for planning the DHC Days 2017. The theme is 'Local to Global Approaches for 
Innovative District Energy Solutions'.
February 21-22, utility companies, district energy operators, software & hardware providers, public institutions, academia and European projects will discuss innovative solutions that could potentially allow district energy systems to carry us to a sustainable future of energy security and smart growth.
Interactive round table sessions will focus on urban waste heat recovery, district cooling and bringing district energy to the digital era.
“We are really trying to create a space for various actors to meet and exchange, not only through interesting presentations, but also through matchmaking sessions. They will be organised through a specific software that allows participants to create a profile and select exactly who they would like to meet”, says Emilia Pisani.
Organisers are CELSIUS, Métropole de Lyon, the United Nations Environment Programme’s (UNEP) District Energy in Cities Initiative, and DHC news, in collaboration with AMORCE and SweHeat & Cooling.

Dublin puts DH to the test in the public eye 

Being the capital of a country without large or even medium-sized district heating networks in place, Dublin has great ambitions. The hopes are now high that a central DH project will pave the way for solving national key issues of sustainability and security.

The closest that Dublin gets to district heating today is a few small-scale communal heating systems in new, private developments. They involve a block of apartments or small group of houses fed by a centralised boiler. There are no schemes operated by the public sector, or plans to expand these networks past their small developments.
But the city does not lack in visions for district energy. Dublin’s energy agency, Codema, has carried out several studies of potential DH systems for the Dublin Local Authorities and held workshops to raise awareness among key stakeholders.
”We want to ensure that district heating is considered for all new developments, and also retrofit into other areas where the socio-economic benefits of using DH over fossil fuels are higher than the costs”, says Donna Gartland, Strategic Sustainable Energy Planner at Codema.

Imminent success crucial
The time has come to put district heating to the test in the public eye.
In the Dublin Docklands, a network is being planned that will use waste heat from electricity production.
”It is crucial that this project is successful and leads to expansion throughout Dublin City centre”, says Donna Gartland, pointing out big challenges that need to be overcome. “The biggest challenges for Dublin are the unknowns; DH is new to Ireland and the technical, economic and regulatory aspects are therefore not well understood. Dublin needs to learn from other cities who have grown DH systems from this ‘ground zero’ level and create the easiest pathway to success.”

Solving key concern
For the city and for Ireland, DH networks could make a big difference regarding a concern that grows in several European countries: energy security.  Ireland has very small amounts of indigenous fossil fuel sources, with an 85% import dependency.
“Due to a large number of individual fossil fuel boilers, it is difficult to integrate renewable energy into the heat sector today. There is huge potential in using waste heat from electricity production to offset fossil fuel use in heating. DH will allow integration of many renewable and waste heat sources to lower Dublin’s emissions, energy costs, and decrease reliance on imported fossil fuels”, says Donna Gartland.
