energy saving

Energy independence remains a priority task for most European countries. Along with traditional energy sources, more and more attention is being paid to renewable energy usage. The best solution for city residents is the use of solar energy for the local needs of individual households. However, chaotic installation of solar panels on the roofs has a negative impact on the aesthetic qualities of urban environment. Many problems as well arise during installation of panels itself on the roof structure.

Currently, the problem of energy-saving construction remains extremely relevant. The application of thermorenovation measures for existing public and residential buildings is one of the ways to solve the problem of rational use of fuel and energy resources. In this article, one of the thermorenovation measures is considered, in particular, the installation of additional external insulation to insulate external walls on the example of a general secondary education institution.

The kinetics of the process of drying hot (80°C) and cold (20°C) candied pears were studied. The drying coefficient is found and an analytical dependence is derived for the drying time calculation. Experimental data of the change in the temperature of the thermal agent along with the height of the candied fruit layer was obtained.

 The development of plant-based materials will help to solve the problems associated with the use of agricultural waste, and at the same time to get inexpensive and effective insulation materials based on environmentally friendly local raw materials. The advantages of such materials are availability, fast recovery, low cost, environmental friendliness and low thermal conductivity.

The article presents the results of theoretical research to achieve the maximum effect in determination of the economically feasible level of buildings thermal protection. It must be optimal both thermally and economically, an indicator of which there are the costs. Graphical and analytical dependences are given. The research results substantiate the maximum effect when different thermal insulating materials are used.

An important priority of Ukraine's economic policy is the careful use of energy. The country has a broad-based energy efficiency policy, and energy efficiency is complex, covering both the legislative framework and technical innovations. One of the effective ways to reduce energy costs for the needs of the national economy is to carry out thermal modernization of the heating system. In this article economic indicators of thermal sanitary measures during reconstruction of the heating system of the object are given.

Not only the ecological aspects of the construction projects, but also the energy savings and efficient construction solutions are currently a very discussed topic. In spite of still persisting prejudices against timber-based structures within our region Slovak Republic, wood-based construction systems are gradually beginning to assert themselves in the construction market. Because modern-minded investors and users are beginning to realize especially the ecological dimension of wood-based buildings. Of course, wood-based structures also have many other advantages and disadvantages.

It is shown that solving the problem of energy saving of housing and public objects use is possible due to the growth of production and use of aerated concrete as an effective insulation material, which ensures the implementation of the concept of sustainable development of Ukraine. Analysis of the data of the Ukrainian Autoclaved Aerated Concrete Producers Association has shown that the demand for aerated concrete constantly increases, and the growth of its production is about 40–45 %.

The article describes mathematical model of analyses the energy use costs efficiency (depending on the type and volume of products produced by the machine-building enterprise, the consumption of certain types of energy resources and their use in specific production processes, etc.). Methodology and mathematical model of the plan for modernization of industrial production energy-consuming processes has been developed.

An important priority of the economic policy of Ukraine is the careful use of energy. Therefore, a large-scale energy saving policy is being implemented in the country, and energy efficiency objectives are comprehensive and cover both the legislative framework and technical innovations. A large amount of energy is spent on creating an indoor microclimate in industrial rooms. One of the effective ways to reduce energy consumption for cheling needs is to carry out the thermal modernization of the air conditioning system.
