Urbanisation processes contribute to an increase in the level of harmful emissions in cities, which significantly increases the relevance of sustainable inclusive development based on the principles of decarbonisation and the transition to zero-emission cities. The purpose of the study is to summarise the global experience of implementing sustainable urban development programmes and their transition to zero-emission cities and to develop proposals for its implementation in the substantiation of urban development programmes in Ukraine. The study is based on a system of methods that includes conceptual approaches to sustainable inclusive development based on a balanced approach, generalisation of global digital trends in the transition of cities to zero CO2 emissions, practical results of decarbonisation projects and identification of indicators for their achievement. In the context of the formation of “smart” city strategies in Ukraine, the current areas of decarbonisation of urban development, based on the feasibility and limited funding, are optimisation of urban traffic, creation of “green” zones with zero emissions, implementation of a set of measures and introduction of renewable energy, promotion of projects that reduce greenhouse gas emissions in construction, including their reduction at all stages of the life cycle of buildings, as well as the implementation of a “smart” waste management system Based on a synthesis of international experience, the study outlines the basic indicators for achieving decarbonisation goals, which can be used in the future to substantiate sustainable development strategies for Ukrainian cities.

The paths of electric currents flowing through sleepers and traditional methods of corrosion under the influence of leakage currents are analysed. Based on the results of this analysis, a new method of studying the processes occurring in concrete under the influence of electrical potentials is proposed for comparative studies of the electro-corrosion behaviour of sleepers and other structures with steel and composite reinforcement. The method involves the application of electric potentials, constant or pulsating unidirectional, to the sleeper models and the study of samples extracted from the models using nanoindentation. By means of nanoindentation it is possible to obtain the values of the micromechanical properties of the cement paste, the modulus of elasticity E and the hardness H, which depend on the degree of its electromigration leaching. It is experimentally proved that due to electromigration leaching, E and H decrease, starting from the face of the model, for which a negative potential is applied. The values of unleached and maximally leached cement paste with W/C = 0.35, which is characteristic of concrete sleepers, are determined. It is found that the nature of these dependencies and, consequently, the intensity of electro-corrosion processes in concrete, depends on the nature of the applied electrical potential (constant or pulsating unidirectional) and the type of reinforcement (steel or composite).
分析了电流流经枕木的路径以及在泄漏电流影响下的传统腐蚀方法。根据分析结果，提出了一种研究混凝土在电势影响下发生过程的新方法，用于枕木和其他钢筋及复合钢筋结构电腐蚀行为的比较研究。该方法包括对枕木模型施加恒定或脉动单向电势，并使用纳米压痕法对从模型中提取的样品进行研究。通过纳米压痕法可以获得水泥浆的微观机械性能值、弹性模量 E 和硬度 H，它们取决于电迁移浸出的程度。实验证明，由于电迁移沥滤，E 和 H 从模型面开始下降，模型面施加了负电位。确定了 W/C = 0.35 的未浸出和最大浸出水泥浆的值，这是混凝土枕木的特征。研究发现，这些依赖关系的性质以及混凝土中电腐蚀过程的强度取决于所施加电势的性质（恒定或脉动单向）和钢筋类型（钢筋或复合钢筋）。

The tourists’ contribution to sustainable tourism is not only economic but also in socio-cultural and ecological aspects. As a medium for Instagram content for National Parks in Indonesia, virtual tours contain content to inform and promote that can influence tourists to realize sustainable tourism. Research to evaluate the content of virtual tour narratives is carried out with a quantitative descriptive approach. The quantitative method involves frequency analysis and score calculation for meeting virtual tour evaluation criteria, while the results are explained descriptively. The analysis technique used is content analysis with information and promotion messages of narrative elements evaluation criteria. The results showed that the percentage of virtual tour video content on National Park Instagram in Indonesia was less than content that was not virtual tour videos. The small number is also not accompanied by good narrative elements, only 15% of which have excellent evaluation results. However, two National Parks can optimize virtual tours, Karimun Jawa and Komodo. Increasing the amount of video content, meeting information, and promotion criteria need to be done to optimize virtual tours in National Parks in Indonesia. The results can be used as a guide for evaluating the narrative elements of national park virtual tour videos.

The Floating Solar Photovoltaic (FSPV) systems are expected to perform relatively at a higher efficiency level as compared to ground mounted PV systems. The major factor affecting the operating efficiency of a solar panel is the operating temperature of the PV panel which is relatively lower as compared to ground mounted PV system. To accomplish this, an experiment setup of FSPV system has been developed which consists of solar panels operating at different heights above water surface. The findings indicate that FSPV modules can reduce the module temperature by up to 4°C – 7°C. The performance of FSPV has been analysed under diurnal conditions. The performance has been assessed in terms of power output by utilising module parameters. The results highlight the power output from solar panel under varying heights help to optimize the operating heights of the solar panels over the water bodies to achieve maximum power output. Therefore, it is also advised for FSPV to raise the PV modules to their optimal height. The FSPV systems at 500 mm height provided 1.8-3.78% higher power output than ground mounted PV systems, maximum of all the panels above water.

One way to reduce the diffusion of chlorides deep into concrete is to bind chlorine ions into stable hydration products. It is known that systems containing carbonates have an increased binding capacity towards chlorides. The goal of this work is to study the effect of carbonate additives on the depth of diffusion of chlorine ions in cement composites (mortars). As controls, samples of mortar were made using cement CEM I 42.5 R as binder. In the main samples, 15% of cement was replaced by carbonates - chalk and limestone. The strength characteristics of mortar samples kept in water and in a sodium chloride solution were studied. According to test data, it was established that the compressive strength of samples with the addition of chalk or limestone practically does not change under the influence of a chloride solution. The compressive strength of samples without additives in the salt solution decreased by 8%. The depth of diffusion of chlorine ions deep into cement composites was also studied. It has been established that replacing part of the binder with carbonate additives does not reduce the permeability of porous cement composites for chloride ions.
减少氯化物向混凝土深处扩散的一种方法是将氯离子结合到稳定的水化产物中。众所周知，含有碳酸盐的体系对氯化物的结合能力更强。这项工作的目的是研究碳酸盐添加剂对氯离子在水泥复合材料（砂浆）中扩散深度的影响。作为对照，使用水泥 CEM I 42.5 R 作为粘结剂制作灰泥样品。在主要样品中，15% 的水泥被碳酸盐（白垩和石灰石）取代。研究了在水中和氯化钠溶液中保存的砂浆样品的强度特性。根据测试数据，可以确定添加了白垩或石灰石的样品的抗压强度在氯化溶液的影响下几乎没有变化。在盐溶液中不添加添加剂的样品抗压强度降低了 8%。此外，还研究了氯离子向水泥复合材料深处扩散的深度。结果表明，用碳酸盐添加剂代替部分粘结剂不会降低多孔水泥复合材料对氯离子的渗透性。

The paper aims to investigate the significance of energy efficiency during Ukraine’s post-war recovery and strategies to improve energy efficiency in buildings in mass housing estates. The motivation for improving energy efficiency is to strengthen the country’s energy independence, reduce the burden on the national budget, meet political commitments, and reduce negative environmental impacts. Currently, energy efficiency in Ukraine lags behind that of European Union countries, necessitating a review of policies and strategies in this field. The inefficient energy use by outdated housing structures has a negative impact on overall energy efficiency. To improve energy efficiency in the housing stock, it is crucial to target Soviet-era mass housing estates, which represent a considerable proportion of the country’s housing supply and fail to meet modern standards. This article provides an overview of the energy-efficient renovation strategies applied in Germany. These endeavors involve reducing heat losses caused by convection and conduction, regulating solar gains, and improving the energy efficiency of technical systems that cater to building services and occupant comfort.

Cultural landscape mapping layers historical, spatial, and narrative as an inventory of heritage – maintaining resilient data – knowledge. The traditional house is one of the elements of the historical cultural landscape exploring people’s engagement with the places that they inhabit. Places are literally “mapped” in order to mark essential composed cultural representations of the area. The widespread heritage of traditional houses called Rumoh Aceh is increasingly disappearing along with the development of modern housing demanded by the community. Therefore, this study aims to assemble a repository of the existence of traditional houses in Aceh Besar and classify the use of different building materials, and changes made to the original building materials among them. A range of datasets are collected including the coordinates of the location of Rumoh Aceh and the images of its current condition. The first finding is a map of Rumoh Aceh established in unexplored villages that illustrates the density of traditional Rumoh Aceh spreading among the villages located in Aceh Besar Regency. Secondly, most of the thatched roof – the original roof materials of Rumoh Aceh – is replaced by zinc and repainted with non-wood colours like blue, yellow, and green. In addition, all the results are available online. Thus, it enables people to access the historical Rumoh Aceh landscape embedded in digital data that is resilient and sustainable. The availability of online data is not only for cultural conservation but also for disaster mitigation and post-disaster reconstruction.
文化景观绘图将历史、空间和叙事层层叠加，作为遗产清单--保持弹性数据--知识。传统民居是历史文化景观的元素之一，探索人们与所居住地的关系。对地方进行 "映射"，以标示该地区基本的文化表征。被称为 Rumoh Aceh（鲁莫亚齐）的传统房屋遗产随着社区对现代住房的需求而日益消失。因此，本研究旨在收集亚齐必胜地区现存传统房屋的资料，并对其中不同建筑材料的使用和对原有建筑材料的改动进行分类。研究收集了一系列数据集，包括鲁莫亚齐的位置坐标和现状图片。第一项发现是在未开发的村庄中绘制的 Rumoh Aceh 地图，该地图显示了传统 Rumoh Aceh 在亚齐 Besar 行政区村庄中的分布密度。其次，大部分 Rumoh Aceh 原始屋顶材料--茅草屋顶--已被锌取代，并重新涂上了蓝、黄、绿等非木材颜色。此外，所有结果都可在网上查阅。因此，它使人们能够访问蕴含在数字数据中的鲁莫亚齐历史景观，这些数据具有复原力和可持续性。在线数据的提供不仅有利于文化保护，也有利于减灾和灾后重建。

Urban-parks, as sports and gaming locations, are a new type of landscape facilities in Ukraine, the first of which were created in Kharkiv. The three urban-parks in Kharkiv have been studied: Molodizhnyi, Saltivskyi and urban-park on Yuriyeva Bulevard. Recreational studies and plant inventories have been conducted to determine the popularity of the parks in 2021. The recreation surveys considered two indicators: the degree of recreation and the length of time visitors spent in the park. Field surveys were conducted in August and October. Saltivskyi urban-park was the most visited, and Molodizhnyi park was the least visited. The presence of playgrounds for pre-school children and children with disabilities makes Saltivskyy more attractive. The calculation of the average length of stay of the visitors on the territory showed that the visitors spend from 1,3 h/day to 1,77 h/day in the urban-parks. It is possible to identify shortcomings in the design of urban parks and make suggestions for their improvement based on the results of recreational load and greenery inventory assessment in urban-parks. The inventory showed that the area of green spaces in the urban-parks has decreased as a result of reconstruction. The level of greenery in Saltivskyi and Molodizhnyi urban parks is rather low and does not meet national regulatory requirements. There are 28 plant taxa of 11 families used in landscaping of the urban-parks, the greatest diversity in Molodizhnyi has been observed. It is necessary to optimize the existing assortment of plants. Some of them are not in a good sanitary condition, which has a negative impact on the overall decorative appearance of the plants and the parks in general.

The three urban-parks in Kharkiv have been studied: Molodizhnyi, Saltivskyi and urban-park on Yuriyeva Bulevard. Recreational studies and plant inventories have been conducted to determine the popularity of the parks in 2021. The recreation surveys considered two indicators: the degree of recreation and the length of time visitors spent in the park. Field surveys were conducted in August and October. Saltivskyi urban-park was the most visited, and Molodizhnyi park was the least visited. The presence of playgrounds for pre-school children and children with disabilities makes Saltivskyy more attractive. The calculation of the average length of stay of the visitors on the territory showed that the visitors spend from 1,3 h/day to 1,77 h/day in the urban-parks.

The article describes the optimization of vertical body struts of the bearing structure of the grain hopper wagon. The study included obtaining mathematical models using modern methods of the mathematical planning of the experiment. At the same time, the target function of the optimization was to reduce the material consumption for the strut. Based on the study conducted, it has been found that the mass of the strut, allowing for the optimization of its geometric parameters, is 4.3% lower than that of the existing structure. It should be noted that the optimization model proposed can also be used for selecting the optimal material for the strut, which may additionally reduce the material consumption of the hopper wagon body. The strength of the hoper wagon body with its optimized struts was calculated using the finite element method. The results of the calculation have shown that the strength indicators of the frame under the main operating loading conditions are within the permissible limits. The conducted research will contribute to the development of best practices for modern rail wagon designs with improved technical and economic characteristics.
