Energy skills as a driver to sustainable construction: current status, needs and proposed actions

During the last two decades, intensified actions toward energy efficiency in construction have provoked the implementation of a significant number of EU-funded and national projects that have developed knowledge in the field of energy-efficient (EE) design and construction of new and refurbished buildings. The current study contributes to state-of-the-art research of the best practices in the field of energy skills at the EU level. The methodology used comprised of desk research on the status of the development of energy skills in construction and business, the status of demand, the level of awareness, and the current training schemes and certifications which are offered. The research is based on published reports, publications, and surveys, resulting in the identification of over 500 sources of information relevant to EE skills. Key findings address the challenges related to the transition of EE skills from the national to the inter-regional level, due to methodological differences, language barriers, and organizational issues. Special attention is given to identifying existing practices for the recognition of previous learning (RPL), and to mitigate barriers to further implementation of this method for upskilling and certification of professionals and workers. In addition, we provide a base that shall allow us to evaluate the impact of existing initiatives on EE and digital skills management in the construction sectors through the survey conducted on an inter-regional level, including five different European countries. The survey results show regional divergence in the adoption of energy skills, but also concentrate on more general conclusions that will pave the way for the creation of upcoming training schemes for upskilling of the construction workforce involving both blue collars and white collars, and noting digital skills, cross-craft competences, and skills in renewable sources as the most in-demand to ensure sustainable construction

Seismic upgrading of RC structures through an optimization procedure based on Genetic Algorithm

Nowadays governments are encouraging the upgrading and the reuse (rather than the demolition) of older structures in order to reduce land use and environmental impact due to the construction of new buildings. The choice of the most suitable intervention for the seismic upgrading of existing structures could also be addressed combining member-level (e.g., FRP-confinement of single columns) and structural-level (e.g., insertion of steel bracing systems) techniques, although it may result in a complex technical challenge for engineers, since a huge number of combinations of technically feasible upgrading interventions are theoretically possible to accomplish the desired structural performance. In order to support the intervention choice, an “objective” approach could be implemented making use of recently-invented Artificial Intelligence (AI) procedures. Specifically, the application of Genetic Algorithms (GAs) is usually thought as a suitable optimization procedure in several civil engineering problems. By means of a Genetic Algorithm (GA), the design of upgrading interventions results to be based on one objective criterion related to the cost-effectiveness of the intervention, rather than on the highly subjective “engineering-judgement”. The present paper aims to highlight the capability of a Soft-Computing (SC) procedure in selecting the most cost-effective combination of the aforementioned member-level and structural-level interventions, among the technically consistent ones. To this aim a parametric study on a RC structure based on a similar GA procedure is reported, varying some “engineering parameters” related to the target seismic risk class of the upgraded structure. Relevant differences in the results are observed due to the variation of target of the analyses.

Some reflections on the seismic upgrading and regeneration of existing buildings in the Italian regulatory framework

In recent years, rehabilitation of the built heritage has increased, while construction of new buildings has decreased. A powerful impulse toward the combined structural upgrading and energy demand reduction has been given to the construction sector by means public investments associated with a fiscal incentives. Design exercises and real execution of interventions highlighted the role of the building envelope not only in the case of energy demand reduction, but also in the case of increase of structural and seismic performance of the buildings. This paper moves from an interdisciplinary research on the role and opportunities offered by multifunctional exoskeletons in the regeneration of buildings in urban areas. Herein the attention is focused on the relation between structural solutions for seismic upgrading, the technical standards related to the structural design and the regulatory framework concerning existing buildings and their relations with the urban environment. Some reflections on clashes generated by innovative and effective structural solutions for performance upgrading of existing buildings are also reported with the aim of defining some needs of integration and coordination of some crucial aspects of current regulatory provisions in the field of architecture and building engineering.

Специфіка господарських відносин у теплоенергетиці України

The main directions of Ukraine’s development in the medium term are the recovery and development of the country after the russian armed aggression, as well as the reform of the mechanisms for managing and regulating the economy in general and the thermal power industry in particular in accordance with the criteria set for accession to the EU. The aim of the study is to identify and generalize the specific features of economic relations in the thermal power industry of Ukraine. The article proposes a classification of factors that can be used to characterize the heat supply system of a particular settlement; the Ukrainian legislation regulating relations in the field of heat supply is studied; the prerequisites for reforming the heat supply sector in the direction of creating regional thermal energy markets are determined. The features of the organization of heat supply in the regions and settlements of Ukraine by types of energy carriers and the structure of thermal energy production are studied (steam or hot-water boilers, combined heat and power district heating, thermal power plants, nuclear power plants). The structure of thermal energy production in some large cities of Ukraine is analyzed. It is determined that an important feature of activity in the field of thermal supply is the centralization of capacities. An analysis of thermal supply systems in large cities of Ukraine has been carried out and it has been proved that the simultaneous use of both large generating capacities and small autonomous boiler houses is typical. Based on the study of existing projects of new buildings from the Database of Energy Certificates of the State Agency on Energy Efficiency and Energy Saving of Ukraine, it is proved that in recent years, in the design and construction of new residential buildings, there has been a tendency to abandon district heating. The features and priority of the use of various heating schemes in residential new buildings of the country are determined. The ownership structure of economic entities in the sphere of district heating of communal energy in Ukraine is analyzed. The number of unprofitable and profitable enterprises of thermal power engineering is studied in the context of forms of ownership. The features of economic relations in the thermal power industry of Ukraine are generalized, which generally characterize the specifics of the organization and functioning of this sphere and constitute the basis for its further reform and post-war development

Application of the Smart House System for Reconstruction of Residential Buildings from an Obsolete Housing Stock

The smart home is amongst the most promising areas of development of communication and information technologies. In order to assure safety, comfort, and resource conservation for all users, a smart home should be viewed as a high-tech system that combines the benefits of automation technologies and contemporary construction methods. Installation of the system is possible during the construction of new buildings as well as during the reconstruction of existing buildings. In this study, the smart home system’s overall idea is considered, the necessity of using resource-saving systems and technologies is supported, and the integration of such systems with the reconstruction of low-rise residential buildings is examined. The study generated a representation of the smart home system for a particular reconstruction project as well as an application for controlling the system using a mobile device.

The independent component analysis with the linear regression – predicting the energy costs of the public sector buildings in Croatia

In the European Union, the public sector buildings are considered significant energy consumers and are, thus, the subject of several directives that aim to ensure the renovation of existing and the construction of new buildings as nearly zero-energy buildings. Therefore, as part of the decision making, it is necessary to properly plan the renovation or construction. This research provides models for predicting the energy costs of the public sector buildings, which are dependent upon its characteristics (i. e., constructional, occupational, energy, etc.). For this purpose, a real data set of Croatian public buildings was used, which included 150 variables and 1724 observations. Since the data set consisted of a large number of variables, the motivation for the dimensionality reduction was addressed first. Then, the independent component analysis, the principal component analysis, and the factor analysis were performed as the dimensionality reduction methods for variable extraction. The results of these analyses were used as inputs for modelling the energy costs of the public sector buildings. The obtained models were compared to the model built on original variables. The obtained models show the application potential in decision making for building renovation and construction in the public sector of Croatia, whereas the best performance of prediction in terms of RMSE and SMAPE was achieved by the model that integrated the independent component analysis with the linear regression.

Comparison of Characteristics of a ZnO Gas Sensor Using a Low-Dimensional Carbon Allotrope.

Owing to the increasing construction of new buildings, the increase in the emission of formaldehyde and volatile organic compounds, which are emitted as indoor air pollutants, is causing adverse effects on the human body, including life-threatening diseases such as cancer. A gas sensor was fabricated and used to measure and monitor this phenomenon. An alumina substrate with Au, Pt, and Zn layers formed on the electrode was used for the gas sensor fabrication, which was then classified into two types, A and B, representing the graphene spin coating before and after the heat treatment, respectively. Ultrasonication was performed in a 0.01 M aqueous solution, and the variation in the sensing accuracy of the target gas with the operating temperature and conditions was investigated. As a result, compared to the ZnO sensor showing excellent sensing characteristics at 350 °C, it exhibited excellent sensing characteristics even at a low temperature of 150 °C, 200 °C, and 250 °C.

Actions to reduce carbon footprint in materials to healthcare buildings

Building sector is a major contributor to the emissions of pollutant gases, which are responsible for health-damaging effects of climate change. To quantify and reduce these emissions. This comparative study is presented between two buildings that could have a sanitary or any other type of use. Both buildings have similar characteristics, except for their structures, one made of metal and the other of concrete. The design, structural calculation and three-dimensional dimensioning were performed using Building Information Modeling (BIM). The budget and the product carbon footprint study were also carried out, to calculate the level of emissions of each building. The study determined higher emissions for the metal-structured building, with 621.234 tCO2/tmaterial compared to 446.707 tCO2/tmaterial for the concrete building. To reduce these emissions, measures related to the replacement of the previously selected materials, by other materials with lower emission rates and identical functionality were presented, such as the replacement of metal building roof polyurethane, or the composition of cement for the concrete building. Both actions represented a reduction of 84.61% CO2 emissions for metal envelope building and 31.765% for the concrete structure. The results of this work will help to select more sustainable materials to use in the renovation of existing buildings, or in the construction of new buildings. For example, health-related buildings, currently in high demand, given the current pandemic situation caused by COVID-19.

The Study of Quality of Life as a Guide to Urban Regeneration Analysis of Estepona’s New City Hall as a Sustainable Model

Given the immersion of cities in a global situation of social emergency since the latest environmental and health events, current research on increasing the quality of life of citizens has become a priority in the attempt to provide the set of sustainable strategic conditions that must be met in favour of the necessary urban regeneration associated with the improvement of the habitable environment. Thus, being directly concerned by this matter, the construction of new buildings will have to follow concordant dynamics aiming at the improvement of the quality of life of their users and of the city as a whole, thus contributing to their mandatory healthy, habitable and equitable nature. It is necessary to redefine in the design of buildings certain potential criteria with a positive effect on the quality of life. These can be grouped into the following five key factors that define architectural work in relation to its habitability conditions: identity, character, image, materiality and implementation. These quality-of-life descriptors are assessed in a particular building, which serves as a real case study as follows: the new town hall of Estepona (Malaga, Spain). The aim is to provide an answer to the potential use of indicators that determine the improvement of the quality of life provided by a building in the city as a whole. The fact that it is a public building also turns it into a model of management that is consistent with the requirements of sustainable environmental progress in the general interest of a socially just city.

Carbon Emissions of Construction Processes on Urban Construction Sites

For Europe to achieve “climate neutrality” by 2050, emissions from all economic sectors must be reduced to the absolute minimum. In addition to changes in raw material extraction and building material production, the construction industry must embrace emission-free construction sites. The present paper suggests a method to calculate carbon emissions on construction sites by defining all fuel-consuming processes while relying on established European standards. A set of system boundaries is defined to single out emissions that occur in the construction industry sphere. These definitions are essential to calculate savings through the entire construction process. This method is subsequently used to assess the carbon balance of four exemplary construction sites in Austria, which cover the total span of the construction life cycle. Results show that the largest share of emissions is attributed to transport during the construction of new buildings, followed by emissions from demolition and building processes.

Historical Evolution and Scenarios Up to 2050 of Heating Energy Consumption and CO<sub>2</sub> Emissions of Residential Buildings in Vienna

Today, the building sector poses a major problem concerning fossil fuel energy consumption and the corresponding emissions of local pollutants and global greenhouse gases (GHG). In addition, an increasing number of people are living in urban areas, and it is becoming challenging to provide the necessary living space and energy for heating in fast-growing cities. Currently, urban areas host approximately 50 % of the global population and generate 70 % of GHG. The core objective of this study is to analyze the historical development and to derive scenarios for the possible future development of the overall CO<sub>2</sub> emissions in residential buildings in Vienna up to the year 2050, considering all relevant emissions from final energy, as well as the embedded emissions from the construction of new buildings, retrofitting, and rooftop apartment extensions. This study indicates the following key points: (i) The renovation of buildings by improving the thermal quality is the most favorable scenario strategy and produces the least CO<sub>2</sub> emissions. (ii) The transition to the sustainable heating of buildings requires at least a temporary "investment" in embedded CO<sub>2</sub> emission, e.g., in retrofitting and insulation of buildings to harvest reductions in CO<sub>2</sub> emissions in the long run, from a smaller amount of energy used for heating. The major conclusions of this study are as follows: (i) To implement the most favorable renovation scenario, strong policy measures are required, such as standards for new buildings and for building retrofitting, as well as subsidies to ensure an accelerated refurbishment rate of the old low thermal building stock. (ii) It is important to reduce the CO<sub>2</sub> emission of the final energy carriers, especially of district heating, by increasing the usage of renewable energy carriers such as biomass, solar, and geothermal.

Nowa tożsamość. Przyczynek do badań na przykładzie architektury Państwowej Fabryki Wagonów „Pafawag” we Wrocławiu

The “Pafawag” State Rail Coach Factory was the first plant to be opened in post-war Wroclaw, one of the most important enterprises producing rolling stock, and at the same time a place of work for the population arriving in Wroclaw after 1945. Based on the history of the factory, the article is an attempt to define the new identity created after the World War II in the Recovered Territories. By means of a few selected examples from the field of architecture, the issues of the adaptation of post-German buildings and their adjustment to the needs of the time are addressed, as well as the construction of new buildings which, as a result of the process of humanisation of work, turned out to be objects of importance for the employees of this plant. The historical landscape outlined in the text is an example of the influence of the workplace on the area – in this case the “Pafawag” State Rail Coach Factory – on the new identity in post-warWroclaw.

Handling Of Minor Crime Cases (Tipiring) Through Restorative Justice As An Effort To Overcome Overcapacity Of Prisoners

As one of the sub-systems of criminal justice, correctional institutions (Lapas) have a role in the implementation of fostering prisoners and correctional students through a correctional system based on education, rehabilitation, and reintegration. In Law Number 12 of 1995 concerning Corrections, it is stated that the correctional system is held in order to form correctional inmates so that they become fully human, realize mistakes, improve themselves, and do not repeat criminal acts so that they can be accepted again by the community. However, in its development, the guidance carried out is not optimal due to the complexity of the problems that occur in prisons. One of the root causes of problems in prisons/detention centers is overcapacity. Various policies have been taken to overcome the overcapacity problem, including through building rehabilitation to the construction of new buildings with the aim of increasing the capacity of prisons and detention centers. However, this policy was not significantly able to overcome the problem of overcapacity considering the increasing number of detainees and inmates who are still much more as a result of the high level of crime in the community. Efforts that may be more appropriate to do to overcome the excess capacity in prisons can be taken by using a Restorative Justice approach, namely a shift in punishment in the criminal justice system that prioritizes justice for victims and perpetrators of criminal acts in addition to alternative punishments such as social work. and others. this policy was not significantly able to overcome the problem of overcapacity considering the increasing number of detainees and inmates who are still much more as a result of the high level of crime in the community.

Life cycle assessment and costing of carbon neutral hybrid-timber building renovation systems: Three applications in the Republic of Korea

Building renovation must be attractive and profitable regarding sustainability criteria to be a competitive alternative to demolishment and construction of new buildings. This study presents the global warming potential related life cycle assessment and net present value life cycle costing of three hybrid-timber building renovation and extension systems. The three systems have been developed for three common building types in the Republic of Korea: residential high-rise (cross-laminated timber system), multi-use (glue-laminated and timber frame system), and residential low-rise (steel and timber frame system). The global warming potential of the renovation systems’ materials and their net present value has been calculated with a parametric design system that facilitates the streamlined calculation of multiple construction options and the resulting environmental and economic impacts. The results demonstrate that the three systems achieve negative global warming potential (apartment: −4.74 kgCO2/m2, mixed-use −0.74 kgCO2/m2, multi-unit: −0.28 kgCO2/m2). Positive net present value can be achieved by selling or renting additional useable floor space created through building extension and renovation, resulting in economically and ecologically profitable alternatives to new construction. The parametric calculation system facilitates integrated economic and ecologic cost assessment and evaluation and allows for multiple scenario comparisons.

Closing the material loops for construction and demolition waste: The circular economy on the island Bornholm, Denmark

The article explores the creation of a closed-loop production and consumption value chain, based on a case study carried out on the island of Bornholm, Denmark. Tests and demonstration of practices and procedures to reuse and recycle construction and demolition waste were conducted, including: (1) developing and implementing resource mapping and selective demolition procedures at three rural demolition projects, (2) assessing the CO2 reduction potentials associated with recycling the selected materials, (3) assessing the value and potential business models that could support the utilization of the materials, and, (4) creating a network between local stakeholders. Based on these activities, the article analyses and discuss economic and practical barriers and potentials for looping materials from demolished buildings back into the construction of new buildings. Finally, the article discusses how the lessons learned from Bornholm could be transferred to other islands and remote areas that are considering adopting a circular economy in their construction and demolition sectors.

ПРОЕКТИРОВАНИЕ ПРЕДМЕТНО-ПРОСТРАНСТВЕННОГО КОМПОНЕНТА ОБРАЗОВАТЕЛЬНОЙ СРЕДЫ С УЧЕТОМ ВОЗРАСТНЫХ ОСОБЕННОСТЕЙ ОБУЧАЮЩИХСЯ

Statement of the problem. The article discusses the relevance of the transformation of the subject-spatial component in the educational institutions of the country. Within the framework of the national project “Education”, there is an active construction of new educational buildings, reconstruction, structural and visible repair. Taking into account the international experience of architectural and planning solutions, when creating or renovating the subject-spatial component of the educational environment, the criteria of safety, openness, accessibility, multifunctionality, etc. are applied. The connection of the subject-spatial component with the social and organizational-technological components of the educational environment is also taken into account, which allows modeling a new educational environment using approaches of international practice of description [Formation of a modern educational environment, 2019]. To achieve a high-quality result, teams of specialists from different fields of activity are formed, using the technology of collaborative design, where even before the stage of development of the environment design project, the concept of the development of an educational institution (new or modernized) is taken into account. The purpose of the article is to substantiate the application of the technology of participatory design with schoolchildren for the transformation of the subject-spatial component of the educational environment, taking into account the age characteristics of students and the concept of the development of an educational institution (organization). The theoretical and methodological basis of the study includes activity-based (V.V. Davydov, M.M. Makhmutov, etc.), personal-activity-based (V.P. Zinchenko, V.A. Slastenin), systemic (B.F. Lomov, V.A. Hansen), ecological (J. Gibson), integrative (A.A. Volochkov) approaches, as well as theory of personality activity (S.L. Rubinstein, L.S. Vygotsky, B.F. Lomov, K.A. Abulkhanova-Slavskaya), research in the field of environmental psychology (M. Chernoushek, K. Levin, J. Gibson, V.A. Yasvin). All in all, 155 students of grades 6–8 of the MAOU “Secondary school No. 157” of Krasnoyarsk took part in the study. The following samples were formed for the study: all respondents studying separately in grades 6, 7, 8. An ascertaining experiment was conducted with the use of a diagnostic complex to identify the characteristics of the activity of students [Parfenova, Safonova, 2022]. During the implementation of the formative experiment on the creation of a subject-spatial component of the educational environment, open observation was conducted in natural conditions and the method of focus groups with students was used, during which the needs for additional project activities using the technology of participatory design were identified. Research results. The study confirmed the importance of the subject-spatial component of the educational environment for students. In the semantic universality of the stimulus “school”, the weight of the category “subject-spatial environment” is more than twice the weight of the categories “Psychological atmosphere”, “Educational process” and almost four times the weight of the category “Teacher”. The results of studying the activity of students showed that the conditions in the educational environment limit the manifestations of activity or do not contribute to the emergence of the need for activity. The model of the subject-spatial component of the educational environment proposed by us promotes the development of students’ activity and is not limited to the walls of the school, classroom or adjacent territory within its borders. During the formative experiment, the need for independent participation in the transformation of the environment in adolescents aged 13–15 years was identified, for which we applied the technology of participatory design. Conclusion. Transformation of the subject-spatial component of the educational environment is the possibility of synthesis of the educational process, transformation of the environment, self-determination of students. Having identified the age range in which it is important for students not just to come to school as a place, but to realize the need for its transformation, we can conclude that the proposed model of the subject-spatial component of the educational environment, created on the basis of participatory design, contributes to the development of the activity of personality, subjectivity, and individuality of students.

ЕКСПЕРИМЕНТАЛЬНІ ДОСЛІДЖЕННЯ ТЕПЛОПРОВІДНОСТІ ТЕПЛОІЗОЛЯЦІЙНИХ МАТЕРІАЛІВ ІЗ МІНЕРАЛЬНОЇ ВАТИ

According to the analysis of domestic and foreign literature sources, it is noted that reducing energy consumption to create an optimal microclimate of buildings involves reducing heat loss through external enclosing structures. Construction of new buildings and thermal modernization of existing ones is carried out with the use of different properties of thermal insulation materials, passport data of manufacturers on their characteristics need to be clarified in determining the energy efficiency of buildings. Mineral wool was selected for experimental studies of thermal insulation material used to improve the thermal insulation shell. The energy efficiency of mineral wool was studied using an installation with a climate chamber with a homogeneous heat flux over the cross-sectional area of ​​the sample. To register the change in the amount of heat flux, thermocouples were used, which are located at different points of the climate chamber with a sample of mineral wool. Data on the change in temperature during the observation period before the stabilization of the heat flux was determined by the automatic registration unit. The change in time of the temperature regime at different points of the mineral wool sample is obtained. The thermal conductivity, which characterizes the efficiency of the thermal insulation material made of mineral wool, was calculated according to the known Fourier formula for stationary thermal regime from the values ​​of the temperature difference in the characteristic cross sections of the sample. The discrepancy between the values ​​of thermal conductivity of the investigated sample and the passport data of thermal conductivity of mineral wool provided by its manufacturer is revealed.

Recycling and upcycling in constraction

Waste is a serious environmental problem that poses a threat to the environment. The article describes the features of the use of recycling and upcycling in the construction industry. Comparison of the possibilities of these two approaches is relevant for determining effective strategies for the use of recycled materials and products in the context of the post-war reconstruction of Ukraine. Article purpose is to manifest the possibilities of using materials used in construction and their scope in load-bearing structures and decorative elements. Modern methods of handling secondary materials in construction were evaluated by the method of analysis of literature sources. Based on the comparison of existing recycling and upcycling projects for the construction of new buildings, the possibilities of using construction and demolition waste and solid waste in construction are determined.In the construction industry, waste can be used in the following ways: through the reuse of materials generated during construction and demolition and recycling — processing waste into raw materials used in the production of building materials. There is also experience of successful use in construction of municipal solid waste generated not in the construction industry — upcycling. Materials and products for upcycling in construction are either the result of creative search of customers or executors of the project, or the result of previous organized work on the collection and sorting of solid waste. Therefore, in order to spread the effective use of upcycling, it is necessary to develop a solid waste management infrastructure and disseminate successful experience in project implementation. For efficient and cost-effective recycling on a large scale it is necessary to introduce and disseminate selective demolition practices; collection and separate storage of construction and demolition waste on the construction site; recycling and disposal of materials along with construction to reduce transportation costs
