Opis:
Scientists from all over the world recognize that saving energy in households is currently a very relevant topic. Energy resources are a very important factor for each country's economic vitality. Not only the country's replenishment in energy resources is important, but also the reduction of energy consumption volume. The Objective of the study: to assess the energy savings in households potential, applying the measures aimed at the behavior change of the population through energy-saving direction. Methodology: yhe impact of behavior change of the population measures is assessed according to the criteria of efficiency and effectiveness. In order to assess the potential for energy savings in households, the following methods, such as an experiment, the control group formation scenario, household questionnaire, were used. The questionnaire was designed to supplement the experiment, in order to gain deeper knowledge of the household, to obtain more detailed information about the nature of the behavior, to identify barriers to behavior change, and to select a control group of households to carry out the experiment. Data, results and main contribution of the paper: research shows that people's behavior related to energy saving is influenced by a number of macro-level and micro-level factors. In the article, the assumptions of the changing behavior of population are analyzed and the specific measures aimed at the behavior changes of the population selection and implementation impact assessment.

Opis:
In this paper, concept of energy saving by the use the special recuperation system for hydraulic excavator is studied. This solution is alternative to commercial projects of hybrid systems, which store energy in the hydro pneumatic accumulators or the super capacitors. Suggested solution includes designed system of active counterweight, which cooperates with working mechanism of machine. The hydraulic circuit of active counterweight is connected with the boom standard hydraulic system. The counterweight mechanism is homothetic to working mechanism of the excavator. The homothetic transformation applies to kinematical structure and positions of the centres of gravity. The homothetic transformation provides to static unloading of boom cylinder by the connected counterweight cylinder. The possibility of energy saving by using movable counterweight was estimated during tests. The key parameters of hydraulic system, such as: cylinders velocity, working pressure, oil flow and another were measured on prepared research stand. The comparison of power consumption for standard and modification system during the same work cycles allowed confirms the correctness of the suggested concept for energy saving system. Energy saving ratios for modified hydraulic circuit was calculated for different velocity of boom cylinder and payloads. The active counterweight system for low velocity cylinder of excavator mechanism is ready to application. The hydraulic circuit for higher value of boom cylinder velocity requires resize a few elements for example supply lines.
