“…Scenarios 4 and 5 are simulated according to the future assumptions regarding the decreased electricity tax (tax category 2 in Table 5) planned by the Finnish government, escalated EUA prices (Carbon Price Viewer -Ember, 2021;Official Journal of European Union, 2003), a low-temperature DH (LTDH) network, and finally, with reduced heating demand due to renovations of building stock in the studied region. The renovation measures include the installation of building-level exhaust air or groundsource HPs, low-temperature radiators, solar thermal systems, ventilation, and heat recovery systems, as well as improving the thermal insulation level of the walls and roof (Hirvonen et al, 2021). Two different cost-optimal energy retrofit scenarios -the lightly retrofitted (Renovation 1) and the heavily renovated and thus more costly (Renovation 2) -are considered in scenarios 4 and 5, respectively (Hirvonen et al, 2018).…”

“…Energy efficiency improvement of the Finnish building stock has been studied since the energy crisis in the 1970s. The energy efficiency improvement scenarios have been developed in terms of energy consumption and economic effects [1], energy consumption and cost optimality [2], power need, operational energy consumption and CO 2 emissions [3]. In summary of these studies, structural improvements only make limited energy savings possible.…”

All EU member states have established a long-term renovation strategy (LTRS) and have updated it twice to support renovation of their national building stock to be highly energy efficient and decarbonised by 2050. The new revision of the EPBD is already under way to accelerate progress on climate change mitigation. This paper is an assessment of the third and latest Finnish long-term renovation strategy for 2020–2050 from a low-carbon perspective covering the emissions of energy renovation products as well as heating energy consumption. The renovation strategy of Finland directs measures to structural improvements, more efficient use of building service technologies and changes in heating systems. The measures will reduce CO2 emissions by more than 90% compared to 2020. Only 3–4 percent of emission savings in operational energy are required to offset emissions in accordance with the strategy measures. The measures will meet the CO2 emissions reduction targets of EPBD and Fit for 55 by 2030.

“…Numerous international treaties, such as the United Nations Framework Convention on Climate Change, Kyoto Protocol, and Paris Agreement, aim to reduce greenhouse gas emissions worldwide. Accordingly, most advanced countries have set targets to achieve carbon neutrality by 2050 [1][2][3][4][5][6]. The increased focus on carbon neutrality has prompted extensive research on new and renewable energy technologies.…”

The continued use of fossil fuels is contributing to severe environmental pollution and the establishment of an abnormal climate; consequently, alternative renewable energy sources are being actively investigated worldwide. Further, following global trends, numerous countermeasures aimed at improving carbon neutrality, promoting sustainable agriculture, and reducing fossil fuel dependence are being implemented in the Republic of Korea. Therefore, this study was conducted to investigate the application of renewable energies for greenhouse heating in the Republic of Korea. Three hybrid systems, numbered 1–3, were constructed using a pellet boiler, hydrothermal heat pump, and solar heat collection system, respectively. Thereafter, the heating performance, combined heat efficiency, energy consumption per temperature lifting, and energy cost per temperature lifting of the systems were compared. The combined thermal efficiency results showed no significant differences. However, in terms of energy consumption and cost, hybrid system 1 demonstrated 25.7 and 24.1% savings, respectively, compared with the other systems. Moreover, based on economic analysis via the net present value and life cycle cost analysis methods, the system reduced costs by 29.2 and 27.7%, respectively, compared with conventional fossil fuel boilers. Thus, hybrid system 1 was identified as the most economical system.
