Renovating existing buildings is important for achieving global climate targets, necessitating a comprehensive approach to environmental assessment. Life cycle assessment (LCA) is a vital instrument for comprehensively scrutinizing the environmental impacts of buildings over their lifespan. Despite established standards, the intricate nature of renovations introduces complexities in the application of LCA. Moreover, this research argues that recent policy developments in efficient resource use, circular economy, and energy efficiency have incentivized renovations over building new buildings. This study seeks to scrutinize trends and the utilization of LCA in building renovation research, subsequently offering recommendations for future research endeavors and policymaking. Employing a scoping review methodology, the study maps building renovation research utilizing LCA to evaluate environmental impacts, drawing insights from an analysis of 54 scientific articles published between 2005–2022. The findings demonstrate that when renovating an existing building, the options are limited by the prerequisites from the design decisions decades ago. Thus, setting environmental benchmarks reflected in the variability of scope and functional units used in research is challenging. Recommendations for future research emphasize addressing granularity issues in assessments, improving communication of environmental impacts, considering the assessment scale, and incorporating economic and social impacts. These insights aim to guide and enhance building renovations for a more sustainable future. [Display omitted] • The existing research gaps and future recommendations in building renovation-LCAs. • Significant variations in functional units due to existing building constraints. • Ambiguities in the accounting of module D and the system boundaries. • Limited inclusion of economic and social viability in renovation-LCAs. • Research should investigate more impact categories to avoid sub-optimization.

Indoor air quality is a critical factor influencing athletic performance, particularly in professional sports settings, yet its impact remains underexplored. This study utilizes a panel dataset from 2516 Chinese Basketball Association (CBA) matches across 20 cities in China between 2014 and 2019. We integrate daily air pollution metrics with player efficiency ratings (PER) to investigate the effects of air quality on individual performance. We find that a 10% increase in the air quality index (AQI) corresponds to a 1.4223 decrease in PER, indicating a strong negative effect of poor air quality on player productivity. Different pollutants have varying effects, with some exacerbating the decline in both overall performance and precision in tasks. Notably, older players and international players exhibit greater resilience to air pollution. These insights contribute to the development of a comprehensive index for assessing work efficiency under varying air quality conditions and suggest targeted strategies to mitigate the negative impacts of air pollution in competitive athletic settings. • Uses technical statistics from players in the Chinese Basketball Association. • The data is mixed with the air quality readings taken every day. • Air pollution impacts productivity by decreasing both overall production.

The rising global energy demand has made it essential to reduce energy consumption in the residential building stock. Adding a new insulating envelope with Renewable Energy Sources (RESs) onto the existing buildings’ facade is one way to achieve zero energy consumption in residential buildings. The ENSNARE project aims to semi-automate this process by using prefabricated facade modules and developing new building data acquisition techniques. Prior to this research project, an analysis was carried out and several research gaps were identified. One of the obstacles to using prefabricated modules with RES is that the layout needs to be drawn and adjusted during different phases of the project. That is time-consuming. For this reason, this article describes two new solutions: (1) automated drafting of the optimized layout of prefabricated modules of the facade and the number of solar panels based on the existing residential building model, and (2) automated adjustment of the layout depending on the phase of the renovation project and the accuracy of the measurements in each step. The proposed semi-automated approach has the potential to significantly reduce the time used in drafting the layout of the prefabricated modules, which benefits the whole renovation process, contributing to a more sustainable future for the residential building stock.

Renovation of dirt roads requires a reliable and durable work tool. This article includes the methodology of field and bench tests as well as the results of these tests and conclusions for cutters used for dirt road renovation. The main novelty of the research presented in this article was to determine the wear mechanisms occurring during field and laboratory tests, to determine the differences in wear levels and the cost of renovation of one kilometer of dirt road. Calculations of the efficiency of replacing these working elements and the cost of operating various cutters per km are also presented. The lowest mass loss was characterized by milling cutters Ø25 mm mounted on an expansion sleeve and amounted to 130 g. The dominant wear mechanism that was observed after the renovation of dirt roads was micro-scraping and micro-bruising. For this variant, the cost per 1 km of road renovation was also the lowest and amounted to about PLN 2.

Pipe wear in urban water supply networks is one of the most important challenges faced by water authorities. Older pipes must be replaced by new ones once they reach the end of their service life or are no longer useful due to a rise in demand and changes in surface roughness. Budget limits are one of the most common reasons for the failure of renovation and upgrade plans in water supply networks. In the traditional approach, the whole renovation is done in one phase and does not take into account the growth and development of the system. Therefore, uncertainties due to unforeseen changes are not considered. The present study addresses the renovation and upgrade of a part of the water supply network in Zahedan city via a novel approach. This approach involves dividing the plan into phases and redesigning some of the pipes during 5-year phases based on budget partitioning. To improve the hydraulic performance of the network, a multi-objective simulation-optimization model was developed with the pipe replacement cost and the water supply network reliability as the objective functions that must be minimized and maximized, respectively. For this purpose, the EPANET simulator model was combined with the Gray Wolf Optimization (GWO) algorithm in MATLAB software. The model execution results in each Phase were presented in the form of a Pareto front between the objective functions. This allows the company to renovate the water supply network based on the budget in each phase. After optimization in phase 1, the results were presented as a Pareto front between the network reliability coefficient and the reconstruction cost. One of the optimal answers on the chart was selected as the final design. In this optimal design, 22 pipes at a cost of 276 million Tomans and a reliability coefficient of 48.2% were replaced. After applying changes in the diameter of the pipes according to the design, the first phase was optimized as the basic model of the second phase. In phase 2, 32 pipes were selected and renovated. Similarly, after the end of Phase 4, it was found that the network reliability has increased significantly (150%) and the pressure of all network nodes was within the allowable range. The results indicate that the used approach can considerably increase the reliability of the network in addition to appropriately managing the renovation budget.

By the end of the 1990s in France, the first labels have been created to distinguish the singularity of 20th-century architecture. However, a large part of its building stock suffers from energy deficiencies, and most of them need major retrofitting to align with today’s habitability standards. If current technologies offer a wide array of devices that meet performance demands, their implementation does not always comply with heritage protection goals. As part of a transdisciplinary research project, our team studies the acceptability and feasibility of the renovation of various buildings of the 20th-century, using “the ventilated double-skin”. The goal is to set renovation protocols that incorporate architectural and cultural evaluation in the technical analysis of energy and comfort needs. In this paper, we present our methodology and first results and aim to highlight the importance of complementary approaches to help inform sustainable interventions on this unique heritage.

Reformulating packaged foods has the potential to improve the nutrient density of the global diet. The present perspective illustrates The Kraft Heinz Company’s approach to product (re)formulation to develop healthier product lines that are lower in saturated fats, total sugars, and sodium, and contain health promoting components. Here we present the rationale for The Kraft Heinz Company’s global nutrition targets used for the global innovation and renovation of foods and beverages. The global nutrition targets use a category specific approach to set maximum levels for the main nutrients of public health concern: saturated fat, total sugars and sodium, taking into account product characteristics (typical portion size, eating occasion, role in the diet, etc.) as well as regulatory, technological, sensory and safety constraints. Benchmarking examples illustrate how the nutrition targets are positioned within the United States, France, and Australia. These global nutrition targets serve as part of The Kraft Heinz Company’s environmental, social and governance nutrition commitments and demonstrates how the food industry is improving the nutritional value of packaged foods and beverages both now and into the future.

Abstract Building alterations often occur when the buildings ought to be updated to meet new standards. In such processes, original values of existing buildings tend to be neglected in favor of speed and economic benefits from aggressive alterations. In this research, we investigate the mechanism of architectural alterations that respect the value of existing buildings. The research helps uncover the lasting values of buildings that can be preserved in spite of the need for physical adjustments.

Abstract This paper introduces the concept of co‐renovation, which involves creating a network of people, objects, and events during the renovation process. The study examines the effectiveness of co‐renovation in two ways. First, by promoting an open approach to the renovation process and the resulting house, it is possible to stimulate connections between those involved in the renovation. Second, the creation of a renovation network can encourage a sense of community development, leading to independent regional initiatives that extend beyond the renovation project. To optimize the effectiveness of co‐renovation, it is crucial to foster spontaneous connections, and this paper provides a summary of the factors that contribute to this.

The main site of the project for the revitalization of the 36th quarter of the historical center of Irkutsk is the merchant estate of the Medvednikovs. The buildings are located at the corner of Khalturin Street and Dekabrskikh Sobytiy Street. Built in the classical style in the early 19th century, the surviving houses have been excluded from the list of cultural heritage sites and are in a ruined state. The goal of the project is to restore the historical and cultural value of the site and to adapt it for a cultural center. The choice of function for the object was determined after analyzing the situation and justified by the cultural and educational function of the territory and the needs of residents. The boundaries of urban planning were increased to ensure integrated urban development. The project is the winner of the International Graduation Competition (Kazan) and the XXX International Architectural Festival “Zodchestvo” (Moscow).

This paper presents a scientific analysis of interior design in the restoration process of the National Museum of Arts of Moldova. The interior design segment is historically researched through the genre of architecture, from the historical compartment of the XIX-XX century. In the same context, several works of various architects who designed important constructions in Kishinev are analyzed. The study highlights the role and responsibility of interior design in the process of restoration and capitalization of the national cultural heritage. It also analyzes the correspondence or synchronization of new implementations in design with the stylistic concept achieved in the historical period.

Brick sewers were designed as egg-shaped, pear-shaped, bell-shaped, vaulted, and even rectangular (sometimes with granite ceilings and floor slabs). In exceptional cases, circular sections were also made of brick. Efforts were made in order to ensure optimal flow conditions, and also that the cross-section was adapted to the shape of the rock mass pressure line. This is due to the fact that the most advantageous shapes for masonry collectors are shapes in which no tensile stresses will occur in any part of the cross-section under the influence of external loads. Nevertheless, sewage conduits degrade over time. The boundary conditions of their use also change, which affects the magnitude of mechanical and hydraulic loads. Further use of a sewer in such a case requires its renewal, and less frequently, modernization that results from the necessity to change its function. This is usually done by introducing a new conduit into the interior of the renovated or modernized sewer, which in literature is called a liner.

In this article, we argue that Muslim scholars have divided divine knowledge into three categories including substantial knowledge, knowledge of the creatures before creation, and knowledge of creatures and objects after creation. In fact, there is disagreement among the Islamic thinkers over the divine knowledge, its quality, and features. The point of controversy revolves around the wide disagreements over the divine knowledge of the creatures and objects both before and after creation. Therefore, divine knowledge over creatures before and after creation has always been the point of ongoing and challenging rational and dialectical discussion and debate. We examine this issue comparatively between the three Islamic thinkers (Mulla Sadra, Shaarani and Assar).

Cultural heritage monuments are, to a large extent, public goods of collective consumption, and their preservation is in the public interest of the society as a whole. The benefits arising from the owner's investment and resulting from the existence and the use of a cultural heritage monument are usually not ``consumed'' solely by the owner, but, to a greater or lesser extent, by the whole society or a particular group. In the case of the renovation and remediation of cultural heritage buildings, the life-cycle costs are determined in the operational phase, before the intended renovation or remediation. They should be used to select an economically sustainable solution, with the maximum potential to preserve the cultural and historical value. The paper presents the application designed for the elaboration of plans for the renovation and remediation of cultural heritage monuments, developed in the form of a web interface. The application processes data at the level of individual structural elements. For faster and more comfortable users' work, a database of type objects is used, which combines primary data from the level of structural elements.

Within the European project e‐SAFE (Energy and Seismic AFfordable rEnovation solutions), this paper presents the experimental tests and modeling attempts for a class of Asymmetric Friction Connections (AFCs) tested in the laboratories of the Norwegian University of Life Sciences. The AFCs are part of the seismic retrofitting solution, called e‐CLT, based on installing Cross‐Laminated Timber (CLT) panels in reinforced concrete structures using friction connections. The authors carried out experimental tests on AFCs fixed with screws to a CLT panel to observe the contribution of timber to the total dissipation performance. The investigation is based on 20 cyclic test data with two different setups. The main one includes a CLT panel and screw connection, while the second one isolates the friction behaviour to evaluate the influence of the screw connection. A modified LuGre hysteresis model for friction is developed to simulate the experimental cyclic response of the tested specimen. The model possesses a direct physical meaning, and it explicitly depends on the slip force and the pre‐slip stiffness. The optimized model is used to assess the performance of the AFC by varying the pre‐slip stiffness and the slip force. [ABSTRACT FROM AUTHOR]

We propose a facile, cost-efficient, environmentally friendly, and scalable process to renew single-walled carbon nanotube membranes serving as extreme ultraviolet (EUV) protective pellicles. The method comprises of high-temperature treatment of the membrane by Joule (resistive) heating at temperatures higher than 1000 °C and pressure below 0.3 Pa. Using model Sn aerosol nanoparticles, the primary contaminant from extreme ultraviolet light sources, we demonstrate the proposed method to clean the membrane with the power consumption as low as 20 W/cm2. We show the proposed method to cause no harm to carbon nanotube structure, opening a route towards multiple membrane renovation. We confirm the applicability of the approach using in situ deposition from the semi-industrial EUV light source and subsequent Sn-based contaminant removal, which restores the EUV-UV-vis-NIR transmittance of the film and, therefore, the light source performance. The proposed method supports pulse-cycling opening an avenue for enhanced protection of the lithography mask and stable performance of the EUV light source. Additionally, the approach suits other composite contaminants based on such species as Pb, In, Sb, etc. [Display omitted] • We propose a technology for cleaning nanotube membranes from aerosol contaminations. • The technology is proven for semi-industrial EUV pellicles and aerosol filters. • The technology is energy efficient (20W/cm2), fast (3 min), sustainable, and scalable. • The cleaning causes no harm for nanotube structure as well as membrane morphology. • The technology is suitable for Sn and In while can be extended for other composites.

Currently the importance of bridge inspection and maintenance is widely recognized. It seems reasonable to mention that a gantry is essential for the inspection and maintenance of a long span bridge. Therefore, most long span bridges are equipped with a gantry as a permanent access tool. Honshu Shikoku Bridges compose three highways and one railway between Honshu and Shikoku islands in Japan. Three routes consist of 17 long span bridges with a main span of more than 200 m. Since the bridges had been constructed with accumulating knowledge for construction and maintenance from 1975 to 1999, a gantry had also been improved for gaining better access. Despite the improvement, there were still a certain number of inaccessible elements and components, so further improvement is being made to increase access capability due to growing requirements of arms-length inspection and maintenance. There are 152 gantries in total, consisting of four types of gantries: a suspended gantry, an internal gantry, a tower gantry, and a cable gantry. This article presents the gantries installed in the Honshu-Shikoku Bridges, containing improvement histories for each type of gantry in the construction and several efforts to improve access capability in the maintenance.

With the evolution of the renewal concept and protection mode of dwellings in ancient city in the new era, the guidelines for the renovation of dwellings compiled in the past have shown obvious limitations of the times. Its compilation form is too simple, and the content is slightly insufficient, and it is difficult to scientifically guide the high-standard renovation of traditional dwellings in the new era. In the compilation of the Technical Guidelines for Renovation of Yangzhou Traditional Dwellings, the core concept is "continuing the style and texture of the ancient city, inheriting the construction technology of private houses, and integrating innovative renovation techniques", and an overall framework for integrating the technical guidelines for renovation of traditional dwellings in "new era and new concept" is proposed. The classification guidance standards for different types of traditional dwellings and their surrounding ancillary environment are formulated, and the corresponding renovation plans of traditional dwellings are systematically drawn as supplementary guidance documents for the relevant classification guidance standards.

This study presents the retrofit acoustic dq1esign of the Italian theatre "Cavallino Bianco". In its historical configuration, the hall had a curved roof with a pressed-plant fiber ceiling, which was demolished and replaced with a wooden roof without a false ceiling, leading to an increase in volume and a worsening of the reverberation time. This study proposed the realization of a wave ceiling and the application of sound-absorbing and reflecting panels on the walls, which have already been implemented. These modifications have affected the acoustic characterization of the theatre, as shown both through on-site measurements during the main construction phases and through numerical simulations. The reverberation time, clarity index, and speech transmission index (STI) are evaluated considering all the variations in the hall over different construction times, and the optimal solution is identified with regard to different specific uses. The final configuration with the new roof, by reducing the volume of the hall and using sound-absorbing materials, significantly reduces the reverberation time (e.g., at 2000 Hz, this reduction is from 2.33 to 1.47). In addition, the hall at full capacity with chairs and people shows evident improvement in terms of the clarity index, allowing the theatre to be used for a wide range of musical genres such as instrumental, symphonic, and opera performances. As regards the Combos 00 (concrete roof without vertical sound acoustic panels) and 01-a/b/c (wooden roof with draped curtains), the STI values are never lower than 0.42 and never higher than 0.70; therefore, the room never experiences poor or excellent conditions at any point. The Combos 01-a and 01-b, which have a non-performing C80, have a good STI index, confirming the difficulty of achieving a configuration that can be optimal a variety of uses. Combo 01 (wooden roof without vertical sound acoustic panels and no draped curtains), which has a good C80 value, presents a lower STI value, with an average performance. The STI values of Combo 02-a (characterized by wave false ceiling and vertical sound acoustic panels) are never lower than 0.52 and never higher than 0.60; therefore, neither poor nor excellent conditions are experienced in the room, but there is still a slight improvement over the combos 00 and 01.

The relevance of the study is determined by the identified shortage of the urban environment in Russia, namely those types of buildings that meet modern requirements. In large cities, the only way to change this situation is redevelopment. This article considers options for stimulating the development of urban areas and optimization of their use through redevelopment. The definitions of the concepts of redevelopment, renovation, gentrification, revitalization are delimited. The classification of types of programs according to the level of management is performed. The advantages and disadvantages of the redevelopment process are presented. Based on the analysis of the regulatory and legal framework, the authors revealed that the concept of “redevelopment” is not defined in any way in it. The practical experience of implementing redevelopment projects and programs in Russia, including development projects of the main industrial zones of the city of Moscow, which are inextricably linked with the strategic development of the constituent entities of the Russian Federation and the implementation of national projects, is analysed. Special attention is paid to the redevelopment project management issues, proposals are presented to increase the efficiency of program management based on the Japanese P2M project management standard. At the end of the study, the authors revealed the results achieved in the implementation of redevelopment projects and evaluated their effectiveness in terms of various indicators.

Abstract This study explores practical approaches to address future vacant housing problems by investigating various support systems established by local governments in Japan. The investigation aims to clarify the components and application of such countermeasures and identify local governments that have achieved positive results after taking qualitative measures and implementing distinct policies. These countermeasures include renovation and demolition subsidies among other strategies. Budgetary limitations make such systems inflexible and the number of vacant houses under a local government’s purview difficult to determine. While some local governments have secured large budgets and designed policies with wider scopes, others with small budgets have achieved substantial successes by setting up clear visions. Each local government should prioritize key aspects of its regional challenges to design a vacant housing policy that addresses the most urgent goal achievable with a limited budget.

Cette présente étude cherche à mettre en exergue la corrélation qu’il y a eu entre la production poétique de Cheikh Ahmadou Bamba et son action rénovatrice. En effet, le Cheikh a pu, grâce à sa grande sagesse, à son sens élevé de l’action et à sa poésie militante et d’inspiration religieuse, insuffler une nouvelle vie à la société sénégalaise amplement éprouvée par des forces rétrogrades aussi bien endogènes qu’exogène. Cependant, si son mouvement de rénovation est couronné de succès c’est parce qu’il s’est essentiellement appuyé sur un soufisme orthodoxe au service de la communauté. - This current study aims to highlight the correlation between the poetic production of Cheikh Ahmadou Bamba and his renovating action. Indeed, the Sheikh managed, thanks to his great wisdom, his high sense of action and his militant poetry and religious inspiration, to breathe new life into Senegalese society deeply affected by retrograde forces as well endogenous ones. However, if his movement for renewal is successful, it is because it has mainly relied on orthodox Sufism in the service of the community.

The topic focuses on current solutions of interspaces in the renovation and modernization of residential buildings, the design of which is conditioned by the principles of sustainable development and construction. It concerns the integration of closed interspaces in renovated buildings from the 1950s to the 1980s. One example is the frequent glazing of loggias/balconies in original panel construction. The form of glazing of loggias and balconies is not regulated and is chosen by the apartment owners. For these reasons, the integration of interspaces in renovated buildings should be supported by research that will bring new insights about their effect on assessments of the energy performance of residential buildings and their effect on the architectural expression of facades. The paper compares alternatives for the integration of interspaces with an emphasis on the efferc of their orientation. The research should serve to help regulate the glazing of loggias in residential panel buildings.

When impermeable ground bearing slabs are installed in old buildings without a damp-proof course, it is a common belief of conservation practitioners that ground moisture will be ‘driven’ up adjacent walls by capillary action. However, there is limited evidence to test this hypothesis. An experiment was used to determine if the installation of a vapour-proof barrier above a flagstone floor in a historic building would increase moisture content levels in an adjacent stone rubble wall. This was achieved by undertaking measurements of wall, soil and atmospheric moisture content over a 3-year period. Measurements taken using timber dowels showed that the moisture content within the wall did not vary in response to wall evaporation rates and did not increase following the installation of a vapour-proof barrier above the floor. This indicates that the moisture levels in the rubble wall were not influenced by changes in the vapour-permeability of the floor.
