Low temperature district heating and cooling networks (5GDHC) in combination with very shallow geothermal energy potentials enable the complete renewable heating and cooling supply of settlements up to entire city districts. With the help of 5GDHC, heating and cooling can be distributed at a low temperature level with almost no distribution losses and made useable to consumers via decentralized heat pumps (HP). Numerous renewable heat sources, from wastewater heat exchangers and low-temperature industrial waste heat to borehole heat exchangers and large-scale geothermal collector systems (LSC), can be used for these networks. The use of large-scale geothermal collector systems also offers the opportunity to shift heating and cooling loads seasonally, contributing to flexibility in the heating network. In addition, the soil can be cooled below freezing point due to the strong regeneration caused by the solar irradiation. Multilayer geothermal collector systems can be used to deliberately generate excessive cooling of individual areas in order to provide cooling energy for residential buildings, office complexes or industrial applications. Planning these systems requires expertise and understanding regarding the interaction of these technologies in the overall system. This paper provides a summary of experience in planning 5GDHC with large-scale geothermal collector systems as well as other renewable heat sources.

“…District heating plays a key role in achieving ambitious global climate change mitigation goals [17], [18], therefore it is necessary for the authorities to design instruments and introduce benchmarks that would monitor and stimulate DH providers to reduce their greenhouse gas emissions. Decarbonization of DH providers can be achieved by utilizing more efficient technologies or using less polluting energy sources, therefore moving closer towards fully implementing a renewable, sustainable, carbon-free DH system [19].…”

AbstractDistrict heating (DH) has been highlighted as an important part in future carbon neutral energy supply. However, the performance of different DH systems varies a lot and the existing regulations do not always motivate DH companies to move toward more sustainable heat production. Therefore, this article presents novel methodology for Climate index determination which can be further used for the comparison of DH systems. The Climate index includes seven different indicators which show DH system performance according to energy efficiency, sustainability and environmental impact dimensions. The methodology is applied for 20 different DH systems operating in Latvia. The results show that the performance of 5 natural gas-based DH systems is below the determined climate benchmark.

“…In this paper we present the steps and method of our integrated strategic heating and cooling planning process performed for the case of Brasov. The discussion and implementation of different scenarios and policies in line with the presented planning process and the assessment of different policies and their impact on different renewable heating options are presented in [14] and [15] respectively. In the here presented planning process "Integrated" means on the one hand, that the connection of the heating and cooling sector with at least the power sector is included and on the other hand integrated means that the demand and supply are not seen as independent dimensions but that heat savings and the future development of heating and cooling demand influence the economic efficiency of different supply options and that they are interlinked and also linked to other sectors.…”

In this work a method for integrated strategic heating and cooling planning on regional level is presented and applied for the case study city of Brasov. The overall methodology comprises the calculation of the costoptimal combination of heat savings with either district heating or individual supply technologies for different building groups located in different areas according to the availability of a current district heating network. This optimal combination is calculated for different scenarios and framework conditions, and different indicators like total system costs, total CO 2 emissions, share of renewables etc. are calculated and compared to analyse the economic efficiency as well as the CO 2 reduction potentials of various options to save heat and supply heat in the buildings. The results of the assessment show that at least a certain amount of heat savings is cheaper than all assessed heat supply options for all building groups but that renewable supply options are not the most economical alternatives per se in the assessed case study under stated conditions. The presented integrated planning process reveals that a long term planning is essential to reach decarbonisation goals and that current framework conditions should be adapted to generate more favourable conditions for renewable heating systems.
