Energy conservation: policy issues and end-use scenarios of savings potential. Part IV. Energy-efficient recreational travel

Introduction. Nowadays, the formation of a policy of the energy-efficient economic activity is a necessary condition for revival of the national production, growth of innovative attractiveness, sustainable development, as well as achieving the European standards for energy security. Development of mechanical engineering based on implementing the energy conservation policy and using the energy-efficient policy will benefit domestic enterprises under a competitive environment. Purpose. The article’s purpose is to analyse the state of domestic mechanical engineering, as well as to reveal opportunities and prospects for enhancing energy efficiency and ensuring energy security. Methodology. The methodological basis of the scientific paper encompasses fundamental provisions of economics, scientific cognition, the general scientific principles, and historical and system approaches to studying a matter of the formation and development of energy conservation and energy efficiency in the industry of mechanical engineering. Results. The article examines the state and indicators of development of the industry of mechanical engineering, as well as prospects of implementing the energy conservation policy. The authors have analysed directions of investment support of enterprises. The authors have determined factors conducing to activation of the government activity for ensuring energy security of enterprises of the industry of mechanical engineering. The authors have proven that the latter is a foundation of the economic potential of the country, since the state of socio-economic development of Ukraine depends on a level of efficiency being inherent to the activity of enterprises operating in this industry.

This article draws on the experience matured while working with low-enthalpy geothermic installations both in the design and executive phase as well as ongoing monitoring, within the scope of energy conservation as it relates to building and construction. The goal is to illustrate the feasibility of adopting the ESBE certification protocol (Certification of Energy Efficient Low-Enthalpy Probes) aimed at optimizing the harnessing of local geothermic resources to satisfy the energy requirements of a building, measured against the initial investment. It is often the case, in fact, that during the course of a construction project for a given low-enthalpy installation, we verify incompa tibilities with the local geologic and geothermic models, which, if inadequate during construction, can compromise the proper functioning of the installation and its subsequent operation. To this end, the ESBE method, which adheres to the governing environmental regulations, and which takes its cue from technical statutes within the sector, permits us to validate via verification, simulations and tests, the geothermic field probes used in construction in an objective and standardized manner, thereby joining and supporting the most recent protocols for energy certification of buildings (LEED 2010, CASACLIMA 2011, UE 20120/31 Directive). ESBE certification operates through a dedicated Certifying Entity represented by the REET unit (Renewable Energies and Environmental Technologies) of FBK (Bruno Kessler Foundation) of Trento. The results obtained by applying the ESBE method to two concrete cases, relative to two complex geothermic systems, demonstrate how this protocol is able to guarantee, beyond the correct execution in the field of geothermic probes, an effective coverage of the energy requirements of the building during construction adopting the best optimization measures for the probes in keeping with the local geological and geothermic model.
