“…Moreover, Japan is developing actively the "new energetics" which includes renewable energy sources (RES), high-efficiency gas-and coal-burning thermal power stations, cogeneration, heat pumps, fuel elements etc. Particularly, more than 10 mln of heat pumps were installed by 2014 all over Japan (Kaneko, Uchida, Shrestha, Ishihara, & Yoshioka, 2018;Shrestha, Uchida, Ishihara, Kaneko, & Kuronuma, 2018;Farabi-Asl, Chapman, Itaoka, & Noorollahi, 2019).…”

Purpose is the analysis of world practice of applying the best available techniques to increase energy saving and energy efficiency of mining enterprises being the important factor of the economic development. Methods. The research methodology is based on the scientific approaches: historical-evolutionary, interdisciplinary, integration, process, and situational. Methods of retrospective, categorical, and system analysis as well as modeling have been applied. The analysis was performed on the basis of both initial information sources (original texts of legislative documents, strategies) and material of the international analytical organizations (International Energy Agency, World Bank) as well as the data of official statistical records. Findings. For the first time, different variants of the best available techniques in Japan, the USA, and the EU have been analyzed as well as the role of a state in applying institutional measures of energy efficiency support, including mining complex, and prospects of its use in the Russian Federation. It has been determined that energy efficiency is the effective and economically feasible tool in reaching sustainable development of the national economy. It has been demonstrated that energy saving and increased energy efficiency may reduce the needs in investment, raise industrial competitiveness and consumer welfare as well as improve environmental protection owing to the reduced greenhouse gas emissions and decreased air pollution. Energy efficiency growth has direct effect upon the industrial competitiveness; it can be achieved by means of innovations. Originality. Emphasis has been put on the key scientific and technical aspects and approaches stimulating increased energy efficiency in the developed countries under the effect of strong, coordinated, and consistent national policy in different sectors of economy. Practical implications. The carried-out analysis is useful in terms of the innovative and technological development of different industries of the Russian Federation in the context of its complicated cooperation with European countries and the USA, dependence on foreign technologies, and limited access to them.

“…Heating ventilating air-conditioning (HVAC) systems such as groundwater and air heat pump systems coupled to borehole heat exchangers (BHE) have been used increasingly because they are among the cleanest and most energy efficient heating/cooling systems for houses, multi-residential buildings, public offices, or farms [1][2][3][4][5][6]. Because of the incentives for these systems by the Italian government, often the design of ground source heat pump (GSHP) systems is not adequate and superficial.…”

Heating ventilating air-conditioning (HVAC) systems have been increasingly widespread in Italy: they can exploit renewable energies, are energy efficient systems, do not directly consume fossil fuels, and in the post-pandemic era, have also been subject to incentive processes by the Italian government. In South Tyrol, subject to harsh climates in both the winter and summer seasons, ground-source heat pump (GSHP) systems can be an excellent solution for the air conditioning of buildings. Unfortunately, too often, the design of HVAC systems with borehole heat exchangers (BHEs) is not adequate, and therefore, an innovative and expeditious numerical solution is proposed. A new numerical element (named Type285), written in Fortran code, was developed for TRNSYS 18 and able to implement the main features of BHEs and the surrounding aquifer. Type285 was compared with numerical models present in the literature (using hydrogeological software such as MODFLOW) and validated with the experimental data. The demonstration of the exchanged energy increase between the BHE and subsoil due to the increase in the groundwater flow velocity was carried out and evaluated. The choice to simulate BHE in TRNSYS using Type285 can be a fast and advantageous solution for HVAC system design.

“…Ground-Source Heat Pumps (GSHP) are highly efficient heating and cooling systems, mainly diffused in Europe [1] and North America, and recently increasing worldwide [2][3][4]. By means of closed-loop Ground Heat Exchangers (GHE) they exploit the low-depth ground as a heat source or sink, namely a "shallow geothermal energy" in principle available everywhere.…”
