The specified terms in the summary report "Energy saving" and "Energy Efficiency". Energy saving is considered as a system of organizational measures, technological and technical solutions that provide a reduction in energy consumption and other resources without compromising the quality needed energy consumer. Energy efficiency is largely determined by economic and other quantitative characteristics obtained as a result of the implementation arrangements, technological and technical solutions that provide a reduction in energy consumption, water and other resources in relation to the volume of products and services. It takes into account that the energy efficiency of any building depends on a combination of factors such as: architecture, insulation, air tightness, ventilation and quality of design and technological solutions and the execution of works. In conclusion, it is stated that by using energy conservation principles, it is possible to significantly improve energy efficiency, and ideally design the building with a zero energy balance.
The article deals with the problem of improving the technology of wood impregnation. Mathematical modeling is used as a research tool. Using the logistic approach, the calculation formulas are obtained in which the properties of wood that affect the laws of impregnation are considered in an integral form. The adequacy of the simulation results is confirmed by their consistency with experimental data for samples of aspen wood. By means of the developed model the analysis of laws of impregnation is executed and quantitative estimations of the simulated process are obtained. It is established that the concentration of impregnating liquid in the wood increases almost linearly at the initial stage of impregnation, and the duration of this stage in the simulated process is about two minutes. However, according to the instructions of the manufacturer of the impregnating liquid, impregnation should be carried out by immersion in the solution for 60 seconds, which is less than the duration of the rapid impregnation stage. This means that to improve the quality of impregnation and economical consumption of impregnating liquid impregnation should be carried out by immersion for at least 120 seconds. The research prospects are connected with the specification of the model parameters depending on the wood species and impregnation technology.
Due to the selection of the building shape, orientation and space filling of light apertures can be optimized exposure to the outside air in the heat balance of the building. An important role is played by the choice of materials and building envelope as well as the location of the sequence of layers in multilayer structures. In addition to building envelopes (walls, floors, windows and doors) for "energy efficiency" in the house and still meet the HVAC system through which the heat is also lost. Therefore, only a comprehensive approach will yield the best possible result to the building heat saving. Knowing the place of maximum heat, you can provide measures to eliminate leakage of heat available for use of the building means as improving energy efficiency at home begins with the elimination of "heat leaks". The same thermal control method makes it possible to identify and maintenance of heat leakage caused by invisible on visual examination of the destruction of the inner layers, shrinkage and deformation of the heaters when the device
The work on artificial regeneration in Karelia, it takes about 30 million seedlings annually. Coniferous seedlings grown in forest nurseries. Of this number, more than 6 million seedlings were grown with closed root system under greenhouse complexes. Four greenhouse complex of Karelia is currently applied the technology of growing seedlings of softwood with closed root system. This technology in Finland developed. The substrate compositions prepared according to standard technology, except for peat, include dolomite powder and complex fertilizers. Annual demand of greenhouses in peat substrate is about 200 tons. In the future, with the increase in the cultivation of planting material with closed root system, the substrate needs to be increased. In this paper, we propose a new technology of using logging residues to prepare substrates. At this, for the six million seedlings with closed root system costs amount to 420 thousand rubles/year when grown using traditional substrate, 257.6 thousand rubles/year using the proposed substrate; prices change over time, but their ratio remains approximately the same.
