“…In order to prioritise possible energy efficiency measures, one can evaluate the technical and economical results, the social and environmental impact and different other aspects [1]. Even more, the implemented energy efficiency measures in different energy system elements can have a complex nature, for example, the renovation of buildings and reduction of energy consumption causes a necessity to also change the operation conditions of district heating system [2].…”

The main aim of this study is to evaluate the results achieved by implementation of different support policies in form of subsidies for energy efficiency improvements and transition to renewable energy sources. The article compares the energy efficiency measures in district heating systems with other support program. In order to assess the effectiveness of implementation of different renewable energy technologies and energy efficiency projects, the levelized costs of saved energy for different support programs were determined. Authors compared different co-financed projects related to replacement of fossil fuel energy sources in district heating (mainly to biomass) and the installation of new biomass boilers, heat pumps, solar collectors and other local technologies in municipal buildings. Results show that financial support for energy efficiency measures in industrial enterprises and district heating systems has been most cost-effective, mainly due to the low co-financing rate (30%) and the high potential for energy savings in different production processes. Authors have identified the blind-spots within the funding allocation for different municipalities, which is not always dedicated to achieved energy savings.

“…In a more detailed approach, some success factors for the adoption by stakeholders can be related to innovation theory (Mlecnik, 2013;Rogers, 2003). For example, the more compatible proposed solutions are with the local context of the stakeholders, the more likely they are to be accepted by these stakeholders.…”

“…On the one hand, different tools that allow to analyse the potential of rehabilitation at different levels and scales, from an assessment of previous energy consumption and energy modelling, are being explored. In this research line, there are different studies in different European countries (Lidberg, Gustafsson, Myhren, Olofsson, & Ödlund (former Trygg), 2018;Monge-Barrio & Sánchez-Ostiz Gutiérrez, 2018;Romanchenko, Nyholm, Odenberger, & Johnsson, 2020), that show the diagnosis of the real state of the housing stock and energy saving potential based on different energy simulation scenarios. In those, different rehabilitation proposals applied to the entire district heating are assessed, with the aim of reaching a net zero energy consumption neighbourhood.…”

Renovation at district scale is a key strategy to reduce CO 2 emissions by optimising the implementation of renewable energy sources and taking advantage of economy of scale. This paper focuses on analysing good practice examples on energy renovations at district scale. The paper adapts a qualitative research methodology in four phases, including the multi-perspective analysis of nine exemplary renovation projects in six European countries, including identification of drivers and barriers of different stakeholders.It is found that the drivers for a district renovation are not restricted to energy savings, but typically also include improving the overall quality of life as well as the image and economic value of a district. Moreover, the need for financial models that can alleviate split-incentive problems between investors and resident organizations is identified.Barriers for carrying out a district renovation include that there is a need to comply with energy standards, that the renovation scope had to be limited to avoid a noticeable rent increase and that resettling of tenants during the renovation is often not possible.Lessons learned include that good communication amongst the different stakeholders, especially with residents, plays a key role for the success of the project. Furthermore, a strong leadership is needed to coordinate activities due to the great number of stakeholders.

“…The primary energy saving can be highly dependent on the existence of co-generation units in the DH system [7]. Investments into increased energy efficiency can be economical mainly through installations of ventilation heat recovery systems [8]. However, studies of how new buildings, apart from apartment buildings, interact with heating systems in the long-term are scarce despite the importance of such interactions for smart energy systems [9].…”
