“…At least two publications addressed the issues of wear and tear of high-temperature systems-Čulig-Tokić et al's research describing Croatia [20] and Zhang et al's research describing China [21]. The impact of climate change and construction (excluding network renovation) on the annual heat demand and linear heat density (heat demand per meter of network trench length) was described in [22,23]. The ownership of the various components of the DH system is of great importance when it comes to losses and repairs, because the ownership pays for them.…”

The goal of this paper was to evaluate heat loss and the demand of district heating (DH) in the context of the fourth generation DH concept using a data-driven approach. The heat loss profile was calculated with GIS Zulu© (software (8.0.0.7539, Politerm, LLC, St.Petersburg, Russia) using eight various states of insulation, detailed information on thermal conductivity, internal heat transfer coefficient, and geometry of the concrete trench. There is a strong correlation between the heat sold and the average annual outdoor temperatures. The outstanding episodes are extremely rare, and the difference in the overall pattern is elusive. The results of the annual heat production and annual heat loss analyses were compared using three different estimation methods. The new method was the only one that showed a positive effect after the complete modernization of thermal insulation. The actual proportion of heat loss is much higher at 16%, while the actual heat delivery is less than anticipated at 85–86% only. The trend of the normative approach is correct but cannot determine changes in network heat loss due to aging. The method focuses on the effects of the state of insulation and actual supply temperature levels. The transition to smart energy systems includes strategic and progressive energy planning, as well as new pricing rules and tariffs. Thus, the method presented is the first step in the transition towards the fourth generation DH networks.

“…Yet, only few subareas were volatile to these scenario applications. Recently, Andrić et al [34] evaluated the impacts of global warming and building refurbishments on techno-economic parameters of district heating systems. In their analysis, every decade, the whole building stock was selected for renovation.…”

Background: District heating is widely used for thermal energy supply and offers a broad range of benefits like the possibility to integrate decentral heat supply technologies or to foster the utilisation of renewable energy sources. Thus, district heating has the potential to gradually contribute to a more sustainable thermal energy supply and to consequently facilitate the energy turn. However, due to specific requirements of this technology, strategic planning is required for the successful implementation of district heating networks. Previous research mainly focuses on either economic, environmental, or technological aspects of district heating. This study therefore aims to execute a comprehensive assessment of district heating systems in the following four sections: (1) integrated spatial and energy planning, (2) costs, (3) resources and (4) environment and climate. Methods: To this end, the recently developed Eco.District.Heat kit (EDHk) is used to evaluate and rate eight case studies consisting of 14 different urban typologies, while considering the aforementioned sections of interest. The paper applies the EDHk to assess different spatial structures and grid configurations as well as a broad mix of different thermal energy sources. Results: With regard to integrated spatial and energy planning (section 1), the assessment shows heterogenous ratings whereas the case studies exhibit quite constant positive ratings with regard to costs (2), environment and climate (4). Although a lot of material is used for the construction of networks (i.e. resources, section 3), the question whether or not to dismantle old grids for resource utilisation cannot be answered definitely. According to our results, future development scenarios in the context of climate change and building renovation until 2050 have little influence on the final ratings. Conclusions: Based on the comprehensive assessment of eight case studies, it can be concluded that district heating systems offer a long-term and sustainable solution of heat supply for different spatial archetypes and types of urban fabrics. Furthermore, the proposed methodology allows users to critically examine planned projects and to detect shortcomings at an early planning stage. The EDHk thus provides a suitable methodology to support strategic decisions in integrated spatial and energy planning.

“…In [53], Andric et al evaluate the impact of global warming and building renovation measures on techno-economic parameters of district heating systems. Based on the case of St. Félix in France, results indicate that the decrease of heat demand proved to be most extensive after the first year of renovation (2020), decreasing by 52% compared to the reference value (2010).…”
