If there is not yet a heat infrastructure in the city, the new development could be an opportunity to develop it in the rest of the urban area as well. If there is no obligation for new buildings to connect, the developer has the opportunity to ensure that all build- ings will be connected and thereby create more value for money.

building level solutions, and, therefore, the most sustainable choice taking into account economic, environmental and social sustainability. If there is not yet a supplier of district heating and cooling, the consumer could engage with other consumers and cre- ate a local energy community in which consumers in the local community look for energy solutions of common in- terest. It could be organized in associations or co-operatives and maybe coordinated with or in cooperation with the city council.

Building owner Our recommendations to building owners are:

Join the planned urban infrastructure for energy, which is the most cost-effective for all consumers compared to

For further reading The EU/JRC report on integrating renewable and waste heat and cold sources, pository/handle/JRC123771 from 2021, includes 8 valuable cases, among them 2 from Denmark, that can inspire others. The public utility Taarnby Forsyning established a smart cost-effective district cooling system despite several institutional and legal barriers. The local community in the small town of Jægerspris established a district heating system to utilize surplus heat from CHP and solar heating and is now in the transition to using fluctuating wind energy. The EU/JRC report on efficient district heating and cooling JRC104437 from 2016 also includes 8 cases, among them 2 from Denmark. The first case shows how 20 local communities in Greater Copenhagen established an integrated district heating system to harvest the surplus heat from CHP and waste to the benefit of all consumers. The second case shows how a consumer-owned district heating company in the small town of Gram has established large-scale solar water heating and seasonal heat storage combined with CHP, heat pumps, and electric boilers. The operation responds to electricity prices as if it was an electric battery, “a virtual battery.” The case on sustainable urban development in The Carlsberg City tions/carlsberg-sustainable-urban-development/ , describes how the developer has implemented the most sustainable solution for heating and cooling and ensured its implementation, making it obligatory for all buildings to connect to dis- trict heating and district cooling (for those with active cooling demand). This is to ensure the most sustainable solution and reduce the negative environmental impact of energy-producing appliances in the buildings.
