Estimating Building Airtightness from Data – A Case Study
Authors: Rasmussen Christoffer , Hviid Christian Anker , Bacher Peder , Calí Davide , Madsen Henrik
Published: March 2021

The focus on energy conservation in buildings is increasing. Despite that, the yearly building renovation rate is only at around 1 %. To increase the renovation rate, new and time-efficient methods used for screening of large building portfolios’ energy saving potential are needed. In this paper, a re-engineered take on the classical energy signature method is applied to two renovated apartments in Denmark. The energy signature model relies on time-series measurements of space heat consumption, outdoor temperature, solar irradiation, and wind speed. The estimates obtained from it consist of—among other things—heat loss coefficient and wind-induced heat loss. This paper focuses on the latter. To validate the model estimate, the airtightness has been quantified by blower door-tests in both apartments: the results showed that one apartment is reasonable airtight, while the other suffers from significant air leakages. The energy signature and two other infiltration models, based on blower door test results, were compared. Good agreement between the results obtained from the data-driven energy signature and the blower door test were found. With use of a simple linear relation between the average infiltration and the blower door test result (q50), from the Danish national building code, the energy signature was found to overestimate the blower door test result (q50) by 33 % for the leaky apartment and underestimate the same air flow by 18 % for the other apartment. Both estimates are within the standard error of the infiltration model in the Danish national building code.

Published: March 2021

The single core Energy Recovery Ventilator (ERV) used in this study is equipped with defrost control that recirculates the exhaust indoor air, while keeps the outdoor air intake damper closed. This defrost strategy has the disadvantage of reducing the outdoor air supplied to the house, which may affect the indoor air quality. First, this paper presents new correlation-based models of supply air temperature T2 after the energy recovery core during normal and defrost operation modes based on laboratory experimental data. A pre-heating coil heats the supply air from T2 to indoor air temperature. Second, a house in Montreal (4356 HDD) is simulated as a reference using TRNSYS program. Since the program cannot simulate the operation under defrost mode, the new models are connected in TRNSYS using equation boxes. The energy use of houses at three locations in northern Canada with HDD of 8798 (Inuvik), 8888 (Kuujjuaq) and 12208 (Resolute), are also simulated, without and with ERV unit. The seasonal energy used for heating the house and pre-heating the supply air is compared with results from Montreal. Compared to the case without heat recovery, the ERV unit leads to energy savings: 24% (Montreal), 26% (Inuvik), 27% (Kuujjuaq), and 27% (Resolute). Compared to the minimum standard requirements, the outdoor airflow rate due to defrost is reduced by 4.7% (223 hours) in Montreal, 19% (1043 hours) in Inuvik, 13% (701 hours) in Kuujjuaq, and 24% (1379 hours) in Resolute.
Continuous automated ventilation heat recovery efficiency performance assessment using building monitoring system
Authors: Kull Tuule Mall , Mikola Alo , Tukia Andres , Köse Ahmet , Petlenkov Eduard , Thalfeldt Martin
Published: March 2021

The performance of ventilation heat recovery has high impact to the total energy consumption of modern buildings and its sub-optimal performance results in a remarkable energy penalty. There are several issues, which can significantly affect the heat recovery efficiency such as the inaccuracy of sensors, errors in control systems, mechanical defects and incorrect setting of the system. In addition, the direct comparison of the designed and measured heat recovery efficiency is not necessarily meaningful due to varying boundary conditions e.g. mass flow rates. The main focus of this paper is to develop and demonstrate a simple automated method for monitoring the heat recovery efficiency of ventilation units using building monitoring system (BMS). As the supply and extract air mass flows and temperatures may differ from the calculated initial design parameters, the proposed solution is to analyse the heat recovery efficiency using the number of transfer unit (NTU) method. With this method the efficiency is always calculated by the limiting mass flow, meaning that the warm exhaust air can not transfer more energy to the cold supply air than it is able to contain. As a result, the NTU method gives us the possibility to continuously compare the result to the temperature efficiency declared by the producer of the unit. The developed method demonstrated that the application of NTU method enables identifying sub-optimal performance of ventilation heat recovery, which would not have been revealed by direct comparison of temperature efficiencies. In some cases, low measured temperature efficiency was associated with problems not connected to the heat recovery heat exchanger. The method also enabled to estimate the additional heating costs due to the decreased heat recovery efficiency.
Modelling of Wax Actuators in Underfloor Heating Manifolds
Authors: Kull Tuule Mall , Thalfeldt Martin , Kurnitski Jarek
Published: March 2021

Finding sources for power grid balancing has become increasingly important with more renewables used for production. In buildings, heat pumps could be utilized among other electrical appliances. The heat pumps would work at full power to balance the overproduction in the grid. However, short-term grid flexibility announces the consumption need up to 5 minutes in advance, which can prove a problem to control. When there is no current energy need in the building, all valves are closed. That means that when a heat pump with overridden control starts working at the maximum frequency, its full power heats up the local circuit very fast, especially when there is no storage tank. Whether the heat pump overheats and cannot be used for balancing the grid or the whole system opens for heating depends on the regulating valves and their opening speed. For underfloor heating systems, the valve opening speed is slower than for other systems as wax actuators are used. This paper focuses on how to model these wax actuators and determine the opening time to provide input for further studies on flexibility. A physical and a linear segment model are parameterized and the results show that the wax actuator fully opens the valve in six minutes.

Additional requirement to the Swedish nearly zero energy requirements
Authors: Wahlström Åsa , Maripuu Mari-Liis
Published: March 2021

This study has analysed which options would be appropriate to use as additional requirements to the main requirement of primary energy number in the new Swedish building regulations. The starting point is to ensure that buildings are built with good qualitative properties in terms of the building envelope so that low energy use can be maintained throughout the life of the building despite changes in installation systems or the building’s occupancy. The additional requirements should aim to minimize energy losses, i.e., to ensure that the building's total energy demand is low. The following possible additional requirements have been examined: net energy demand, net energy demand for heating, heat power demand, heat loss rate and average heat transfer coefficient. In order to ensure that the additional requirements will work as desired and to explore possibilities with, and identify the consequences of, the various proposals, calculations have been made for four different categories of buildings: single-family houses, apartment buildings, schools and offices. The results show that the suggested option net energy demand will not contribute to any additional benefits in relation to primary energy number. The other options analysed have both advantages and disadvantages and it is difficult to find a single additional requirement that fulfils all the pre-set demands.

Published: March 2021

This study investigated the effect of passive strategies (orientation, thermal mass of building structure, window opening, and window properties) and the usage of an active cooling system on energy demand and indoor temperature conditions of a detached house in Finland in the current (TRY 2012) and future climatic conditions (2050). So that nine different cases were defined and simulated. The goal was to improve the indoor temperature conditions in the cooling season and analyze the effects of global warming on energy demand. Regarding the results of passive strategies, in the current climate, using openable windows would be the best solution for decreasing the cooling demand and providing acceptable indoor air temperature of the spaces. In this case, 96% of the time in the cooling season, the indoor temperature is below the maximum recommended indoor temperature (27 °C) of the thermal environment category III of the standard EN 15251 and EN 16798–1. While using an active cooling system in the hall of the upper floor, it is the only studied solution that can provide thermal comfort in all the spaces during the cooling season in both current and future climate based on the standards. In the future 2050 climate, the heating demand decreases much more than the amount of increase in the cooling demand. So that the total electricity demand of electrically heated detached houses in the future climate would be less than in the current climate.

Published: March 2021

In this study, nickel aluminium bronze alloys (NAB) with appreciable densification and improved microhardness was consolidated via spark plasma sintering technique. The NAB alloy was synthesized from starting elemental powders comprised nickel (4 wt.%), aluminium (6, 8 & 10 wt.%) and copper using dry milling technique. Starting powders were homogeneously milled using gentle ball mill for 8 h at a speed of 150 rpm and a BPR of 10:1. Subsequently, the milled powders were consolidated using the spark plasma sintering technique at 750 °C under a compressive pressure of 50 MPa and rate of heating (100 °C/min). Furthermore, the powders and sintered alloys were characterized using SEM and XRD to ascertain the microstructural and phase evolutions during the synthesis of the NAB. The density and microhardness of the alloys were further investigated to ascertain the integrity of the sintered alloys. The results indicated that the increase in aluminium content resulted in the formation of intermetallic and beta phases on the alloy after sintering and the microhardness of the alloys improved with the increase in aluminium content.

Published: March 2021

Global climate change is posing threats for sustainable crop production. Supra-optimal temperature and water stress are among few causes of global climate change which can cause significant damage to yield in various crop species including sunflower. Therefore, a study was initiated to develop new sunflower hybrids which may have higher seed yield and water use efficiency in current scenario of global climate change. Parental inbred lines were selected on the basis of cell membrane injury and cuticular waxes; these parental lines were used to develop various cross combinations. These cross combinations were evaluated at two locations and seasons. Some newly developed hybrids (H7, H8, H9) showed lesser days to flowering, high water use efficiency, high or comparable yield, kernel to seed% and oil contents% than high yielding commercial check Hysun.33. Water use efficiency (WUE) showed significant and high correlation with seed yield in both seasons. WUE decreased in spring season when compared with the autumn season due to high evapo-transpirational losses. General combining ability analyses showed that parental lines i.e. C.249 and RH.344 were the best combiners for water use efficiency and seed yield and may be exploited for the commercial development of drought resistant hybrids.
Contexte économique et stratégie de déploiement : les SMR sur la brèche
Authors: Crampon Cécile
Published: March 2021

Partout dans le monde, on assiste à un engouement pour les SMR (Small Modular Reactors), mais il leur reste de nombreux défis à relever. À commencer par celui d’ordre économique. Le SMR a une conception modulaire qui permet de maximiser les fabrications en usine avec un acheminement des pièces sur le site d’implantation et ainsi de réduire les durées de chantiers. C’est sur cette base, associée à un effet de nombre, que les SMR espèrent compenser l’effet de taille qui les désavantage par rapport aux réacteurs de forte puissance. Cela suppose de réaliser des SMR en grande série, un même produit pouvant être installé dans différents pays, avec la mise en place de supply chains efficaces et de fournisseurs de niveau internatio¬nal. Les SMR permettent surtout d’aborder de nombreux marchés non accessibles aux réacteurs de grosse puissance, tout en se substituant aux énergies fossiles.

Smart Specialization of Innovative Development of Functional Territories: Strategic Experience and Potential of Ukraine
Authors: Kucherova Hanna , Khvostina Inessa , Ocheretin Dmytro , Bilska Olha
Published: March 2021

The article examines the strategic experience of introducing smart specialization in Ukraine using the methods of strategic analysis, financial analysis, generalization, statistics, critical thinking. It has been proved that the state priorities of Ukraine's strategic development have changed. The concept of providing state aid to industries that cannot withstand competition has been changed to the concept of identifying specialized functional areas based on the principles of reasonableness, sustainability and inclusiveness of development, the ability to integrate into value chains of world markets. The above more locally meets the requirements of the competitive environment, minimizes the risks of scattered financing, increases the level of effectiveness of strategic planning, innovative and technological development of the state as a whole. The inconsistency of the state and regional strategic support for the introduction of reasonable specialization was established against the background of determining the effectiveness of the use of such forms of cooperation as the cluster model and cross-functional interaction. The need for standardization and greater regulation of the smart specialization procedure at both the conceptual, methodological and practical levels is determined. Ukrainian smart specialization is constrained by the insufficient potential for the implementation of regional development strategies, the urgent need to adapt the method of assessing smart specialization in the format of entrepreneurial discovery to the Ukrainian realities of types of economic activity, insufficient funding of potential functional territories, low initiative, diversification and self-organization. The delay in the implementation of reasonable specialization of activities in Ukraine is explained by the need for additional time to reconfigure the socio-economic system at all levels and to understand the territorial needs, the prospects of choosing from existing opportunities and its consequences.

The Discursive Opposition and the “Power of Discourse” in the Ukrainian Mass Media
Authors: Synytsia Iryna
Published: March 2021

The subject of this publication is related to such directions of modern linguistics as critical discourse analysis, media linguistics, and text semantics. The article examines the features of the media discourse of Ukraine on the example of antonymic semantic relations that are the result of modern discursive practice. The media discourse of modern Ukraine demonstrates the facts of the emergence and functioning of the pseudo-antonymic opposition. The research is based on economic topics articles published in Ukrainian online publications during 2019-2020. The texts of the publications are written in Ukrainian or Russian. All articles are devoted to the problem of “betrayal or victory”. The author of the article asserts that the active functioning of the Ukrainian lexemes “betrayal” and “victory” in the media discourse influenced not only the emergence of unusual oppositional relations between these lexemes. The active use of pseudo-antonyms in speech contributes to the destruction of traditional axiological values of Ukrainians and involves them in pseudo-discussions. Thus, first of all, the “power of discourse” is manifested. The author speaks about the formation of an independent discourse “betrayal or victory” in the Ukrainian media discourse. Pseudo-antonyms explode the pragmatic intentions of the sender of the message and are a means of manipulative influence on the linguistic consciousness of the recipient.

Legal Assessment and Speculation on the Topic of Collaborationism in Ukraine. Digital Dimension
Authors: Shaikan Andrii , Shaikan Valentina
Published: March 2021

The majority of modern researchers of the history of WWII and Great Patriotic War (1939-1945), analyzing the events that took place seventy years ago speak about the extreme danger of Nazism, since its aggression, in the case of the Nazis’ victory, would cause a civilizational decline for considerable part of mankind, and would lead to humanitarian catastrophe. A significant number of innocent people got into the post-war repression and their fates were crippled by war and totalitarianism. The author of this paper does not in any way desire to justify activities of collaborators or enemy aiders and deserters, as certain historian critics sometimes mistakenly imagine. Our research aims to show – but not to justify – motives of deeds of a person in critical social settings and incentive factors, which may under certain conditions align one’s behavior with a specific course of action. We believe that any statements concerning the inadmissibility of the Nuremberg International Trial rulings review are incompetent and illegitimate.

Just as there is no ideal society, there is no society without corruption. Fighting corruption is one way to achieve the UN-approved goals of sustainable development. The article summarizes the process of formation and implementation of international anti-corruption standards and their features in different national legal systems. It is determined that the adoption and recognition of standards does not in itself solve the problem, which is why the world is constantly looking for ways to combat corruption, testing new tools and mechanisms to influence corruption risks. This is confirmed by numerous projects funded by international donor organizations. Information technologies create endless opportunities not only for economics development (robotics, blockchain technology, neural networks, artificial intelligence, quantum virtual and augmented reality), but also for the fight against corruption: from e-government and courts, digital public services and tools that report about the facts of corruption, to the means of influencing society through social networks. The article analyzes scientific and professional research in the field of digitalization of anti-corruption activities and substantiates the relationship of these concepts from the standpoint of the impact of IT technologies on combating and preventing corruption. The article summarizes modern technological advances and their implementation in various national legal systems, defines the role of information technology in the fight against corruption and forms an understanding of information technology as a tool to control and combat corruption.

The introduction of new technologies, as well as digital is a new logical stage in the development of society, affecting all areas of humanity, including legal. The digitalization of society is becoming the most important factor in economic growth and is a modern trend in the development of any country in the world. Ukraine is no exception to this list, as it has chosen to bring its national legal system closer to the European Union's legal system and international legal standards, which is a complex and lengthy process. Unfortunately, so far there are no generally accepted and harmonized definitions and legal definitions for the legal regulation of introducing digital technologies in the Ukrainian legal system. This necessitates a more thorough study of implementing digital technologies in the legal field. This article is devoted to the problems concerning legal regulation of remote court proceedings by videoconference, which is designed to simplify access to justice and lead to savings in material and procedural means in court proceedings. The purpose of this article is to identify problematic issues regarding legal regulation of distance litigation in Ukraine and to propose mechanisms for its improvement as well as to harmonize it with international legal standards.

Published: March 2021

The presented article gives the analysis of the modern demographic indicators such as life expectancy, age structure and fertility rate of the population in Ukraine and their geographical differences. The aim of the research is a spatial analysis of the demographic situation to determine the development trends of the population of the regions of Ukraine. In the conditions of depopulation and gradual aging of labor force in Ukraine requirements to its qualitative characteristics, first of all a state of health and average life expectancy grow. Ukraine belongs to the countries with high intensity of depopulation processes that is caused by a number of various factors of economic, socio-cultural, institutional character. Large-scale and protracted depopulation is now a component and one of the most pronounced manifestations of the general crisis demographic situation in Ukraine. The tendencies of influence of average life expectancy on indicators of population aging are investigated in the work. The regional analysis is carried out and territorial differences in indicators of average life expectancy and indicators of population aging are defined. The reasons for such a tense situation have been identified. The paper emphasizes that the development of really effective measures aimed at bringing the oblasts out of the deep demographic crisis and slowing down the progressive depopulation should focus not only on reducing mortality, but mainly on improving the health of the population, which can correct high mortality. These demographic trends increase global demographic asymmetry, give a special sharpness and new "sound" to the demographic problem in the global context, and, in addition, have long-term socio-economic consequences for countries with depopulation and deepening aging. In view of this, there is now a need for a comprehensive scientific understanding of the phenomenon of depopulation and assessment of its possible prospects, the development of a strategy to influence depopulation processes by means of sociodemographic policy. In our country, the study of depopulation factors, its nature and origins, analysis of the peculiarities of the deployment of depopulation and assessment of its consequences have become particularly relevant.

Published: March 2021

Despite the significant success of the human population in the development of the planet's resources, man will most likely never be able to completely get rid of dependence on the material and energy mechanisms of the biosphere. The clearest proof of this is the existence of urban ecosystems, within which human living space is formed. However, there is no consensus among researchers on the participation of social and natural components in the formation of urban ecosystems. Moreover, there is no clear answer to the question of how and through what mechanisms the space of human life is formed in modern cities. The article analyzes the ontological affiliation of the category "living space". Numerous aspects of the formation of modern living space have been studied on the specific examples of urban ecosystems of Kryvyi Rih and Uman. In particular, sample surveys of residents of these cities were conducted, based on the results of which conclusions are made about the quality of living space. Tourist activity and tourist resources are considered by the authors as a field of harmonization of human-environment relations in modern conditions of formation of living space.

The choice of research topic is due to the fact that currently obtaining high yields of winter wheat is closely connected to the widespread use of chemicals, in particular, herbicides, which by their nature are physiologically active substances that can affect both plants and soil microbiota. This, in turn, leads to the search for environmentally safe elements of technologies for growing winter wheat. One such element may be the use of herbicides together with plant growth regulators. The obtained experimental data testify to the protective ability of the growth regulator Regoplant against the winter wheat plants, as evidenced by a decrease in the activity of malonic dialdehyde accumulation, changes in the activity of the enzymatic defense system, decrease the number of epidermis cells and an increase in total rhizosphere bacteria in case of Regoplant use together with Granstar Gold 75, w.g. compared with the experiment variants, where the herbicide was applied without a growth regulator. That is, the use of growth regulator in a mixture with herbicide to some extent eliminates the toxic effect of xenobiotics, which has a positive effect on the state of ecobiosis of winter wheat sowing.

Soil erosion by water is the most important global environmental problem. A modern system for assessing and monitoring soil erosional degradation should be based on the use of remote sensing data. This raises the issue of correct data decoding. The article proposes a method for visual interpretation of eroded soils according to the Sentinel image obtained in the visible range. The authors give some combinations of decoding signs to determine the manifestations of linear and surface water erosion from images. The article shows possible errors in decoding the manifestations of water erosion and gives an example of assessing the erosion of the soil cover based on the results of decoding the Sentinel-2 satellite image. Moderately and heavily eroded soils are reliably distinguished, the area of which, according to the interpretation data, was 2.4% of the area of arable land in the studied territory. In the future, the obtained sample of spectral images of eroded soils can be used to develop an automated method of interpretation based on the principle of "computer vision".

The analysis of the state of ecological sphere development in the medium-size cities of Ukraine certifies the presence of negative tendencies there, exactly, the decrease of population quantity, the growth of numbers of movable sources and the level of population morbidity. There has been suggested a scale to make qualitative and quantitative evaluation of the changes of ecological sphere state according to which indices ascertain the correspondence with their states: 1,0 – 0,75 as high, 0,749 – 0,50 as medium, 0,499 – 0,25 as less than medium, 0,249 –0, as low. It is revealed that high level of ecological development refers to Ivano-Frankivsk (0,777), which is the leader according to the level of planting greenery, the lowest accumulation of waste materials of the 1st – 3d level of danger, the lowest emission of pollutants into atmosphere from stationary and movable sources. Melitopol has medium level (0,57) and is the leader as to the indices of drinking water consumption and is characterized by good indices concerning the waste treatment, considerable expenses spent on nature-protecting activity and low amount of pollutant emission into atmosphere. The cities of Lutsk and Rivne are characterized by lower than medium level of the development of ecological sphere vital activity (0,482; 0,384 in the year 2017 correspondingly), because of a great amount of pollutants emission into atmosphere, low level of planting greenery. The city of Rivne, besides, has the highest indices as to the assumption of waste materials and the least expenses on nature-protecting measures. It is ascertained that the influence of destimulators and stimulators on the level of development of medium-size cities ecological sphere is described by dependencies which look like straight lines at the coefficients of determination R2 from 0,381 to 0,721.

Several surgical methods exist for the treatment of osteochondral lesions of the femoral head. They include osteochondral allograft transfer, femoral osteotomy, microfracture, autologous chondrocyte implantation, and hip arthroplasty. Mosaicplasty is a surgical method in which cylindrical plugs of bone and cartilage are transferred from a donor site to tunnels drilled into the bone and cartilage defects. This paper discusses the use of mosaicplasty by a direct anterior approach without dislocation in the treatment of an acute femoral head osteochondral impaction in a young patient.

Gesundheitsförderung für Lehrkräfte –
Inanspruchnahme von gesundheitsförderlichen Maßnahmen im Setting
Schule
Authors: Burkhardt Birgit , Hoppe-Herfurth Anne-Cathrin , John Nancy , Bilz Ludwig
Published: March 2021

Ziel der Studie Die Studie untersucht die Inanspruchnahme von
gesundheitsförderlichen Maßnahmen durch Lehrkräfte und
die empfundene Passung zwischen Angebot und subjektivem Bedarf.

Methodik Im Schuljahr 2017/18 wurden mittels Fragebogen Daten von
830 Lehrkräfte an allen allgemeinbildenden Schulformen des Landes
Brandenburg zu ihrer Inanspruchnahme, dem Angebot und dem Bedarf erhoben.

Ergebnisse 81,3% der Lehrkräfte haben in den letzten 24
Monaten eine oder mehrere gesundheitsförderliche Maßnahme(n) in
Anspruch genommen. Es fanden sich keine signifikanten Unterschiede
bezüglich des Alters, des Geschlechts, der Schulform und der
Trägerschaft. Für die meisten Bereiche der
Gesundheitsförderung gaben die Lehrkräfte einen deutlich
höheren subjektiven Bedarf im Vergleich zum wahrgenommenen Angebot an,
wobei ein besonders hoher Bedarf für Maßnahmen der individuellen
Verhaltensprävention und der Schulraumgestaltung besteht.

Schlussfolgerungen Bei der Implementierung von
Präventionsmaßnahmen sollte die Passung zwischen Angebot und
subjektivem Bedarf aus Sicht der Lehrkräfte stärker als bisher
berücksichtigt werden.
Diagnostic Analyses of Retinal Dystrophy Genes: Current Status and Perspective
Authors: Bolz Hanno Jörn
Published: March 2021

Over the past decade, novel high-throughput DNA sequencing technologies have revolutionised both research and diagnostic testing for monogenic disorders. This applies particularly to genetically very heterogeneous disorders like retinal dystrophies (RDs). Next-generation sequencing (NGS) today is considered as reliable as Sanger sequencing, which had been the gold standard for decades. Today, comprehensive NGS-based diagnostic testing reveals the causative mutations in the majority of RD patients, with important implications for genetic counselling for recurrence risks and personalised medical management (from interdisciplinary surveillance to prophylactic measures and, albeit yet rare, [gene] therapy). While DNA sequencing is – in most cases – no longer the diagnostic bottleneck, one needs to be aware of interpretation pitfalls and dead ends. The advent of new (NGS) technologies will solve some of these issues. However, specialised medical geneticists who are familiar
with the peculiarities of certain RD genes and closely interact with ophthalmologists will remain key to successful RD research and diagnostic testing for the benefit of the patients. This review sheds light on the current state of the field, its challenges and potential solutions.
