Opis:
W ostatnich latach rynek fotowoltaiki w Polsce odznacza się dużą dynamiką rozwoju. Nowe instalacje fotowoltaiczne to głównie rozwiązania wolnostojące lub dodane do budynku. Stosunkowo mało jest rozwiązań zintegrowanych z obiektem. Korzyści ekonomiczne i jakościowe (odnoszące się do efektów wizualnych), jakie wynikają z użycia systemów BIPV powinny przewartościować dotychczasowe myślenie i zachęcić inwestorów do ich szerszego zastosowania.
In recent years, the photovoltaic market in Poland has been characterized by high dynamics of development. New photovoltaic installations are mainly free-standing solutions or solutions added to the building. There are relatively few solutions integrated with the facility. The economic and qualitative benefits (related to visual effects) that result from the use of BIPV systems should re-evaluate the existing thinking and encourage investors to use them more widely.

Opis:
Improving the energy efficiency of residential buildings is ensured by improving the thermal protection characteristics and the wider introduction of control tools. In order to take into account the influence of individualisation of operating conditions, the study of the regulation of heating distribution of a single-pipe system with bypassed heating devices of a 5-storey typical for Ukraine mass building of the 80s after thermos-modernisation for conditions in Kyiv and Warsaw (Poland) was carried out. On the basis of the simulation model created in the Mathcad software environment for design/rated and average climatic conditions, the influence of internal heat flows into adjacent rooms on the distribution of energy consumption, changes in internal air temperature under the influence of local changes in the heating device flow coefficients were studied. The developed approaches, and the results obtained on the influence of local regulation of devices of vertical single-pipe heating systems can be used to clarify the distribution of energy consumption for heating between individual zones of apartment buildings.

Opis:
Grinding is commonly responsible for the liberation of valuable minerals from host rocks but can entail high costs in terms of energy and medium consumption, but a tower mill is a unique power-saving grinding machine over traditional mills. In a tower mill, many operating parameters affect the grinding performance, such as the amount of slurry with a known solid concentration, screw mixer speed, medium filling rate, material-ball ratio, and medium properties. Thus, 25 groups of grinding tests were conducted to establish the relationship between the grinding power consumption and operating parameters. The prediction model was established based on the backpropagation “BP” neural network, further optimized by the genetic algorithm GA to ensure the accuracy of the model, and verified. The test results show that the relative error of the predicted and actual values of the backpropagation “BP” neural network prediction model within 3% was reduced to within 2% by conducting the generic algorithm backpropagation “GA-BP” neural network. The optimum grinding power consumption of 41.069 kWh/t was obtained at the predicted operating parameters of 66.49% grinding concentration, 301.86 r/min screw speed, 20.47% medium filling rate, 96.61% medium ratio, and 0.1394 material-ball ratio. The verifying laboratory test at the optimum conditions, produced a grinding power consumption of 41.85 kWh/t with a relative error of 1.87%, showing the feasibility of using the genetic algorithm and BP neural network to optimize the grinding power consumption of the tower mill.

Opis:
The impact of harmonic distortions on power grids is a major issue in contemporary power networks as a result of the extensive application of non-linear loads. The purpose of this article is to explore the problem of harmonic distortion in power grids and its impact on the elements of the power grid, such as cable lines and transformers. The Schaffner PQS software product was used in this study to model power grids. New techniques for modeling power grids and finding technical solutions that meet the IEEE 519-2014 standard were introduced. The study finds that harmonic distortion can lead to an additional heat load being placed on cable lines and reduces the power available to transformers, which can decrease their rated power. The application of modern software reduces the time and complexity of calculations, and the availability of software solutions for limiting harmonic distortion simplifies the creation of solutions that meet this standard. Using the methods presented in the study, engineering solutions can be improved, the reliability of electrical systems can be increased, and the loss of electrical energy can be reduced. This can enhance efficiency for design engineers and technical specialists involved in the operation of power grids.
Wpływ zniekształceń harmonicznych na sieci elektroenergetyczne jest ważnym zagadnieniem we współczesnych sieciach elektroenergetycznych w wyniku szerokiego zastosowania obciążeń nieliniowych. Celem niniejszego artykułu jest jest zbadanie problemu zniekształceń harmonicznych w sieciach elektroenergetycznych i ich wpływu na elementy sieci, takie jak linie kablowe i transformatory. Do modelowania sieci elektroenergetycznych wykorzystano oprogramowanie Schaffner PQS. Przedstawiono nowe techniki modelowania sieci elektroenergetycznych i znajdowania rozwiązań technicznych zgodnych ze standardem IEEE 519-2014. Badanie wykazało, że zniekształcenia harmoniczne mogą prowadzić do dodatkowego obciążenia cieplnego linii kablowych i zmniejszać moc dostępną dla transformatorów, co może zmniejszać ich wydajność. Zastosowanie nowoczesnego oprogramowania zmniejsza czas i złożoność obliczeń, a dostępność rozwiązań programowych do ograniczania zniekształceń harmonicznych upraszcza tworzenie rozwiązań spełniających tę normę. Korzystając z metod przedstawionych w badaniu, można ulepszyć rozwiązania inżynieryjne, zwiększyć niezawodność systemów elektrycznych i zmniejszyć straty energii elektrycznej. Może to poprawić efektywność pracy inżynierów-projektantów i specjalistów technicznych zaangażowanych w eksploatację sieci elektroenergetycznych.

Opis:
The presence of water, food and energy crises, both at the global and regional levels, as well as their deterioration under conditions of climate change, with an insufficient level of technical condition of existing irrigation systems, increase the strategic importance of irrigation as the guarantor of the agricultural sector sustainable development. This makes it necessary to increase, foremost, energy and overall (technical, technological, economic, and environmental) efficiency of the closed irrigation network of irrigation systems. In this regard, the complex that includes organisational-technological, technical, and resource-saving groups of measures was developed. Estimation of energy and overall efficiency of the closed irrigation network of irrigation systems at the implementation of developed complex were executed on the example of the agricultural enterprise located in the Petropavlovsk district of the Dnipropetrovsk region of Ukraine. For this purpose, machine experiment based on a use of the set of optimisation, forecasting and simulation models was implemented, including the model of climatic conditions, the model of water regime and water regulation technologies, as well as the model of crop yields on reclaimed lands. According to the obtained results, established that implementation of the complex reduces the consumption of irrigation water by 2.2-30.7% and electricity consumption by 12.9-38.2%. The rate of specific costs decreases from 1.6 to 1.32-1.47, and the coefficient of environmental reliability increases by 5.6-16.7%. At the same time, the profitability index increases from 1.07 to 1.75-2.57, and the discounted payback period decreases from 18 to 8-5 years.

Opis:
Greenhouses are artificial growing environments that can provide the growth factors required for the production of crop plants out of season. In these structures, the low temperature values that occur during the year cause losses in yield and quality because they are not suitable for plant cultivation. In order to be able to grow out of season in these periods, the amount of heat required by the plants should be provided with additional heating. In the study carried out to determine the amount of heat needed in greenhouses throughout the year for the provinces of Kırşehir and Kahramanmaraş, which are located in two different regions of Turkey, the heat requirements that will arise in the presence or absence of a thermal screen in greenhouses with the same characteristics were calculated. In the calculations, the most common tomato plant grown in both provinces has been considered. Accordingly, if the greenhouse temperature is kept at a constant temperature of 18°C throughout the year, the heat energy requirements that emerge during the year are 469.90 kWh m.-2 for Kırşehir and 254.71 kWh m.-2 for Kahramanmaraş. In the case of using a thermal screen, these values were calculated as 401.53 kWh m.-2 for Kırşehir province and 218.91 kWh m.-2 for Kahramanmaraş province. As a result of the study, the amount of heat energy needed in greenhouses in provinces decreased with the use of thermal screens. It has been determined that this situation is extremely important in terms of reducing the share of heating in production costs and the amount of carbon dioxide released into the atmosphere by fossil energy sources used for heating purposes.

Opis:
The purpose of the article is to investigate the state of carbon dioxide emissions generated as a result of wall materials production and the construction industry as a whole. The paper provides a comparative analysis of housing construction in Ukraine and in some CIS countries. Against the background of the indicators of low housing availability and low relative volumes of housing construction, the issue of high energy consumption remains valid. The absolute and relative volumes of greenhouse gas emissions from economic activity of the population of Ukraine are given. The projected consequences for Ukraine from continued CO2 emissions on the same level and temperature rise are estimated. It is deemed that the most suitable wall material for countries with emerging economies is autoclaved aerated concrete (AAC); since it is a structural and thermal insulating material, it can solve the problem of housing construction. The paper shows the key priority of low energy consumption and makes emphasis on lowering the density of the produced aerated concrete, reducing mineral additives and cement production expenses.

Opis:
One of the priorities of the EU economy is to create the best possible conditions for the design and implementation of innovative solutions within the scope of energy efficiency. In recent years, there has been quick technological progress in the field of devices having controlled motor drive used for air purification, and from heating plates, which are applied in the eating places, including restaurants and zones for preparing meals in various means of transport. The research conducted by the EU on EcoDesign requirements showed that range hoods at the stage of their use have a considerable potential of saving energy. The introduction of energy efficiency labels to the market has improved the energy efficiency of these devices and accelerated the transformation of the market to implement energy-saving technologies, which according to the experts, may lead to an annual primary energy saving of 27 PJ/year in 2021, which may increase in 2030 to 60 PJ/year. The authors of this publication researched the fluid dynamic efficiency of a selected range hood, showing the necessity of investments in new technologies. Patented original solutions of the range hoods that can be applied, among others, in such means of transport as passenger ships, cargo ships, and submarines having a zone for preparing meals were presented in this article. An environmental aspect in the context of energy consumption was shown during the phase of using the device for air purification, providing many premises and arguments for future constructional solutions for energy management in various branches of transport and more.

Opis:
Rapid economic, environmental changes and finite energy resources dictate the need for rational use of energy. Civil engineering is the sector responsible for the highest energy consumption. Therefore, efforts should be made to reduce the energy consumption of construction works in progress. An indispensable factor of development is the introduction of modern technologies. Contemporary architectural thought aiming at increasing the share of transparent facades may be helpful in achieving these goals. This is an important aesthetic aspect. Large panes of glass give the building a modern character, but also visually increase the space and passively allow you to acquire large amounts of heat. Despite the difficulties and costs associated with the construction and operation of high-rise buildings, they are erected more and more often, also in Poland. Modern technology and advanced calculation theory make it possible to build these structures much more economically than previous conventional systems. In this paper, I present a variant static analysis of a tall building structure with large glazing.

Opis:
Ways of energy saving in buildings, namely compliance with the regulatory framework of European standards, possibilities to reduce heat losses during energy transportation through pipelines on the example of heating systems and reducing heat losses during the operation of buildings and structures are studied in the article. It was found that, despite the regular updates of the State Construction Norms of Ukraine, the coefficient of thermal conductivity of insulation materials is not brought into line with generally accepted European standards. The second part of the article presents the results of analytical studies of various thermal insulation materials that are widely used in the territory of Ukraine. After comparing the results, we concluded that the most common at this stage of development of insulation materials will not fully satisfy all the requirements, which must meet all the materials for insulation of structures. The use of some materials is impossible of thermal insulation of structures and pipelines with complex configuration. The solution of energy efficiency along with increasing soundproofing properties, reducing the fire hazard, reducing the load on the bearing structures of buildings and structures is possible through the use of aerogel as a thermal insulation material. The material is characterized by low dependence of the thermal conductivity coefficient on changes in ambient temperature, which makes it the best option for use in harsh operating conditions. After analytical studies of various insulating materials, it was found that aerogel in roll in addition to low coefficient of heat transfer is characterized by better operating properties, namely, non-combustibility of the material, environmental safety, light weight, which reduces the burden on the structure, ease of installation, the possibility of using the structures with high rate of sound insulation.

Opis:
The research was aimed at reducing the power consumption for grain cleaning by using energy-saving modes in the electromechanical systems of grain cleaning units. Specific consumption of active energy per production unit was adopted as a criterion for assessing energy-saving operation modes. The applied method of mathematical experiment planning (MEP) reduced the number of experiments to a minimum to obtain a reliable mathematical model of the research object. To determine the optimal specific power consumption, a theoretical method was developed to rebuild the mathematical model. Thus, the minimum specific power consumption of grain cleaning production lines was obtained, which allowed developing science-based rates of power usage that allow energy savings up to 8-10%.
Badania miały na celu zmniejszenie zużycia energii elektrycznej w układach elektromechanicznych linii produkcyjnych czyszczenia ziarna poprzez zastosowanie energooszczędnych trybów pracy. Wpływ czynników energetycznych na jednostkowe zużycie energii elektrycznej badano metodą matematycznego planowania eksperymentu (MEP). Zastosowano jednostkowe zużycie energii czynnej na jednostkę produkcji jako kryterium oceny energooszczędnych trybów pracy. Badania przeprowadzono metodą MEP. Umożliwiło to przeprowadzenie minimalnej liczby badań i uzyskanie wiarygodnego modelu matematycznego obiektu badań. Opracowano teoretyczną metodę restrukturyzacji modelu matematycznego w celu wyznaczenia optymalnej wartości jednostkowego poboru mocy. Zaproponowana technika pozwoliła na uzyskanie minimalnego jednostkowego poboru mocy linii do czyszczenia ziarna oraz opracowanie naukowo uzasadnionych wskaźników zużycia energii elektrycznej. Daje to oszczędności energii sięgające 8-10%.

Opis:
Thermal insulation materials and technologies for thermal insulation of houses were investigated. The widespread use of such materials is due to the saving of fuel and energy resources, in particular, during the operation of buildings and structures. The subject of the analyzed stage of the research is the use of modern thermal insulation materials in construction, comparative characteristics of materials and processes associated with thermal insulation technologies. A list in the form of a table of the most used on the Ukrainian thermal insulation materials with comparative characteristics was considered. The most optimal from the point of view of ecology are ecowool, foam glass and mineral wool. The disadvantages of materials are the high cost of work and installation. Polyurethane foam, relative to other heat-insulating materials, has a minimum thermal conductivity. Also, along with glass wool, it is an excellent sound insulating material. The main requirements for thermal insulation materials are fire resistance. All listed materials correspond to this characteristic, except for expanded polystyrene. The construction industry in Ukraine is dependent on the country's economic factors. Back in 2015, there was a sharp decline in the market volume associated with an unstable political and economic situation. However, a year later, the pace of construction work has noticeably accelerated by 13,1%. This is due to the growth of the real estate market, the level of purchasing power, the popularization of energy-efficient construction in the country, and, therefore, the latest technologies and innovations in the direction of energy-saving materials.

Climate is changing very fast today and this is not natural. We are experiencing the impact of the climate change in many aspects. It is also expected to impact the performance of buildings badly in due course of time. In the recent years, many countries started investing to evaluate energy performances of the buildings and opting for the best suited energy-saving measures. However, this concept may be new in the context of Bhutan. But the expectation of author is that this new concept may revolutionize the building construction sectors in Bhutan. Many studies shows that Buildings are one of the world’s largest consumer of energy and on the other hand strategies are available to reduce the energy consumption. The strategies can be applied right from the design phases for the new buildings and retrofits for the old buildings. In-order to apply the best strategies of energy consumption reduction and to understand building energy consumption pattern, needs to carry out energy performance of the buildings. Therefore, one of the single-story residential building located in Dewathang is chosen as model building for study purpose. The simulation is carried out using OpenStudio and support by sketchup and the results are discussed under result discussion.
