Aalborg Municipality is Denmark´s third largest municipality, with approx. 210,000 inhabitants. The City of Aalborg is both the municipality´s largest city with a population of 110,000 and the capital of the North Denmark Region.

Aalborg Municipality has seven administrations, one of them – The Department of Environment and Energy – conducts holistic planning in sustainability, climate, energy, water supply, waste water and refuse.

Through the years, Aalborg has undergone a huge transformation from industrial town to modern knowledge city with a global perspective.

Aalborg has a strong focus on sustainability and has lent its name to two important agreements on sustainability. The Aalborg Charter from 1994 and 10 years later Aalborg Commitments. In 2014, Aalborg has committed to the Covenant of Mayors. Furthermore, Aalborg has launched the SMART Aalborg initiative to make Aalborg a smarter, more digital and sustainable city.

As part of the ongoing development, Aalborg Municipality wishes to participate in disciplinary collaborations and networks within the EU. The Hotmaps project is a good example of this.

The Municipality of Aalborg has been conducting strategic heat planning since the late 1980s and through the years, Aalborg has made several heat plans for the municipality. As a partner of the Hotmaps project Aalborg intend to include and share our knowledge and experience to the process of developing and testing the tool and to the other pilot areas. In addition, Aalborg expect to learn from the experiences of the other pilot areas and partners in the project.

Kerry County


A strategy for County Kerry’s transition to 100% renewable energy supply. The goal of making a complete heat map for the county.

Kerry is a rural county in the southwest of Ireland and the most westerly point of Europe. The majority of the population lives in rural areas (66%). The main towns in the county are Tralee (23,693 pop.), Killarney (14,219 pop.) and Listowel (4,832 pop.). Agriculture, manufacturing (in particular food processing) and tourism are key economic sectors for the county. Kerry County Council, the local authority for the county is a signatory of the Covenant of Mayors and has been at the forefront of promoting the development of district heating in Ireland. The mission statement of Kerry County Council ‘is to enhance the quality of life of our people and visitors by building sustainable communities and delivering quality services.’

The organization is responsible for the delivery of a wide range of services across the county. The Energy Section is a very small element in a very large organization. However commitment to energy efficiency and reduction of energy consumption is embedded across all sector of the organization. An ISO50001 Energy Management System is currently being implemented across the organization.  The role of the Kerry County Council Energy Section is to track the organizations energy consumption in the delivery of services, encouraging and promoting energy efficiency, awareness and sustainability with an aim to the achievement of national and EU energy efficiency targets.

Kerry County Council have completed a number of detailed feasibility studies for the development of large scale district heating projects in the larger town in the county. These studies have shown that such projects are economically and technically viable with the introduction of a suitable renewable heat incentive in Ireland. Given Kerry’s status in the area of District Heating in Ireland, Kerry County Council took a very active role in working with the government department in relation to the development of a suitable Renewable Heat Incentive and is partaking in a consultation process in relation to this which is ongoing.

Kerry County Council is a signature of the Covenant of Mayors and is committed to supporting the development of sustainable communities and sustainable jobs across the county. Kerry County Council along with a number of active local groups (including Transition Kerry) worked together with a local energy consultant, XD Consulting, in the development of Transition Kerry’s Sustainable Energy Community Roadmap which details a strategy for County Kerry’s transition to 100% renewable energy supply. To this end Kerry County Council are working on incorporating the findings of the case studies and heat mapping exercise completed to date into appropriate legal, planning and development policies going forward.

It is hoped that the Hotmaps project will allow Kerry County Council to build on the existing heat mapping developed as part of the SmartReflex project and result in a complete heat map for the county. It is hoped that the resulting tool can be used in decision making from a technical, financial and planning points of view when potential district heating projects are being proposed and evaluated. It is hoped that it will show the benefit of district heating when compared to individual heating systems and lead to local sustainable job creation and a transition from an over-reliance on imported fossil fuel.

Milton Keynes

United Kingdom

Milton Keynes Council is a Unitary local authority which in the UK is a type of local authority that has a single tier and is responsible for all local government functions within its area or performs additional functions which elsewhere in the UK are usually performed a higher level of sub-national government.

Milton Keynes is a new city, created in 1967 to provide housing and employment for the growing population in the UK. It has a population of 265,000 as of 2016, and is growing at approximately 1.5% per annum. The city’s economy depends on light industry, commerce, warehousing and distribution. The city is laid out on a grid pattern, with wide grid roads surrounding areas dedicated to the city centre, industry or housing.

Milton Keynes has experience of working with developers at a large scale and the city has a long history of supporting innovation and exemplar energy efficiency initiatives.

A usable tool to evaluate opportunities for both small and large scale heating/cooling networks will help our development and planning teams advise on the development of the city. The reduction in resources required to carry this out in a conventional manner will improve our services to the public and help the city meet its carbon reduction commitments.
