Assessing the efficacy of green building design strategies in minimizing energy consumption in commercial buildings of Mumbai: A building performance analysis

This research paper investigates the effectiveness of green building design strategies in minimizing energy consumption in commercial buildings in the bustling metropolis of Mumbai, India. With a rapidly urbanizing and densely populated environment, Mumbai presents a unique setting for assessing green building practices. The research objectives focus on understanding the impact of various green building design features, such as green roofs, solar panels, and floor area optimization, on energy efficiency in commercial structures. The research employs a robust methodology, incorporating regression analysis to analyze data obtained from the Mumbai Municipal Corporation's building energy consumption records. Through this analysis, the study investigates the relationships between green building design parameters, building characteristics, and energy consumption patterns. Key findings indicate that specific green building features, including intensive and biodiverse green roofs and solar panel installations, significantly reduce energy consumption. Additionally, older buildings tend to exhibit lower energy consumption, emphasizing the need for retrofitting existing structures with energy-efficient solutions. The study also underscores the role of occupant density in influencing energy efficiency, with higher occupant rates leading to more efficient space utilization and energy use. The implications of this research are far-reaching, offering insights into tailoring green building strategies to the specific challenges posed by densely populated urban areas. These findings hold significance for sustainable urban development, policy formulation, architectural design, and the global effort to mitigate climate change.

Experimental investigation of sliding-based isolation system with re-centering functions for seismic protection of masonry structures

A sliding-based isolation system is an efficient strategy to enhance the seismic performance of low-rise brick masonry buildings, a common type of construction across the globe. The previously developed isolation systems lack a proper re-centering mechanism. Therefore, in this study, a low-cost isolation system, termed reinforced cut wall (RCW) with an appropriate re-centering mechanism, is designed and tested experimentally using a shake table, which hasn’t been tested previously. Two unconfined reduced scale (1:3) brick masonry buildings were subjected to frequency-based seismic excitation, and the model's corresponding acceleration and displacement response were captured. Compared to the fixed base model, considerable reductions were observed in the acceleration and displacement response in the case of the isolated model. Similarly, the inter-story drift and floor relative displacement response was also reduced in the isolated model. Furthermore, the rebars used for the re-centering mechanism remained within the linear viscoelastic range. Based on the experimental validation, the proposed low-cost RCW isolator was found to be an efficient isolation strategy for low-rise masonry buildings in high seismic regions.

A holistic two-stage decision-making methodology for passive and active building design strategies under uncertainty

In the last decade, many studies focused on finding optimal design solutions considering trade-offs between different aspects of building design. Accordingly, multi-objective optimization (MOO) approaches have been increasingly applied in the building industry. However, certain aspects must be deepened to ensure a more effective decision-making process in the early planning phase. On the one hand, uncertainties should be considered before making decisions to ensure the robustness of the optimal solutions; on the other hand, decisions are made at different times in building planning, and the sequential order of making decisions should be modeled. This paper presents a holistic two-stage multi-objective stochastic optimization (MOSO)-II framework to minimize the environmental impact of global warming potential (GWP) and cost throughout the entire life cycle of a building (phases of A1-A3, B4, B6 and C3-C4), considering passive and active design strategies in two consecutive stages, under uncertainty. Herein, individual/use and political/market uncertainties are considered. As a proof of concept, the proposed framework is applied in a case study for a generic zone in a multi-family terraced residential building type with solid brick construction. The advantages of the proposed framework are validated by comparing it with alternative single-stage MOSO frameworks. Results show that the proposed two-stage MOSO-II framework can deliver a smaller range of solutions with a better performance in terms of lower GWP and cost. It indicates that the proposed framework can effectively assist planners in decision-making by reducing the effort in choosing the proper solution. Secondly, the results also emphasize the importance of passive design strategies in sustainable building planning. In addition, the energy mix structure and cost of energy sources should be carefully adjusted in the future to promote a more ecologically sustainable building design.

Optimization control strategy for mixed-mode buildings based on thermal comfort model: A case study of office buildings

Mixed-mode (MM) buildings reduce air conditioning (AC) energy consumption while maintaining indoor thermal comfort through the appropriate use of natural ventilation (NV). The objective of this investigation was to propose a method to determine the best NV operation range suitable for MM buildings and further to propose a change-over control strategy. First, the usual natural ventilation operating range (NV-range) was obtained based on the upper and lower comfort temperature limits of the adaptive comfort model. The usual NV-range was extended by adding threshold conditions, and then, it was divided into nine natural ventilation operation subranges (NVOSs). Second, the comfort and energy performance of each NVOS were analyzed through a co-simulation for an MM office building in Xi'an, China, as an example to obtain the optimal NV-range for the local climate. The results showed that the proposed optimal NV-range reduced the number of discomfort hours by 248.33 h while increasing the energy savings by 13.29% compared to those of the commonly used NV-ranges. Finally, the control scheme with the adaptive comfort model changed to the PMV model (ACM-PMV-CS) with the addition of a 1.5-h transition period was proposed in order to solve the problem of using the steady-state PMV model directly in the AC mode under the frequent switching conditions between the NV and AC modes. The results showed that ACM-PMV-1.5 h transition period resulted in a reduction in the number of discomfort hours (248.33 h) and a 35.46% increase in the energy savings compared to those of ACM-PMV-CS without a transition period.

Additive manufacturing of multi-materials with interfacial component gradient by in-situ powder mixing and laser powder bed fusion

Defects (e.g., pores and cracks) and high stress concentration derived from the significant mutation in materials are the critical challenge for multi-material structures fabricated by laser powder bed fusion (LPBF). Introducing a transition zone between dissimilar materials with a composition gradient at the interface may be a promising approach to resolve or minimize these problems. In this work, three distinct CuSn10 copper alloy (CuA)/316 L stainless steel (SS) multi-material gradient structures (i.e., CS, SC-1, and SC-2) were fabricated by a LPBF system with in-situ powder mixing and feeding capability. A buffer layer material based on the mixture of the two base materials was introduced at the interface between CuA and SS. The effects of the building strategies and interfacial composition gradient transition paths on the interfacial bonding characteristics were investigated. The microstructure evolution and the underlying interfacial bonding mechanisms were discussed. It was found that the interfacial bonding behaviors were critically dependent on the occurrence of liquid metal embrittlement induced by Cu penetration into Fe grains, as well as the width and microstructure gradient of the diffusion zone and high stress concentration at the interface. A non-uniform melting behavior of CuA and SS powders could be induced by the distinct thermal-physical properties between the two materials, which could lead to lack-of-fusion pores at the interface. In the CS sample, printing SS on the CuA with a buffer layer material could inhibit the formation of Cu-penetration cracks and increase the width of the diffusion zone, which may enhance the interfacial metallurgical bonding. This work may enhance the essential comprehension of improving interfacial bonding strength of LPBF-processed multi-material structures.

Optimization of photovoltaic solar electric power for renewable energy generation and DSM strategies in singular apartment buildings.

This work presents a procedure of optimization (algorithms) for the supervision, control, and management of photovoltaic solar electric power (PVSEP) in singular buildings dedicated mainly to apartments. The basic principles of performance are kept within two big guidelines denominated Renewable Energy Generation (REG) and Demand Side Management (DSM). From the point of view of GER it is assumed that the more electric power is generated -and therefore sent to the electric net- the more income will be obtained. On the other hand, distribution electric nets recently are having problems of apparent impossibility to attend to the demand peaks. For these reasons, from the energetic efficiency point of view it is very interesting to develop a system able to reduce the demand peaks of the buildings, that is to say, to use DSM techniques. Some procedures (algorithms) useful to justify the installation of photovoltaic panels in buildings have been obtained and are presented in this paper. These procedures are expected to be the core of quality scientific production in our group, including some patented designs and utility models.

Determinants of factors affecting readiness of academic institutions to conduct knowledge translation in low- and middle-income countries.

Capacity building strategies have been used to improve uptake of knowledge translation (KT) activities among academic institutions, but little is known about their effectiveness, contextual responsiveness, and adaptability. Many of these strategies target individuals while few address institutional gaps. This research describes the determinants for conducting KT (or readiness to conduct such activities) at the institutional level across diverse LMIC contexts to inform the development of capacity building strategies. We conducted a survey to assess organizational readiness to conduct KT to public health researchers and practitioners from six academic institutions in Bangladesh, Ethiopia, DRC, India, Indonesia and Nigeria and members of a global knowledge-to-action working group. We assessed the frequency of barriers and facilitators to KT and their relationship to age, gender, country, and KT experience. We then performed logistic regression to identify determinants of five underlying factors demonstrated to influence KT readiness in LMICs (Institutional Climate, Organization Change Efficacy, Prioritization and Cosmopolitanism, Self-Efficacy and Financial Resource) along with their composite score, which represented an overall readiness score to conduct KT. A total of 111 responses were included in the final analysis. Participants represented 10 LMICs; a majority were 30-49 years old (57%) and most were male (53%). Most participants had professional foci in research (84%), teaching (62%), and project coordination (36%) and 59% indicated they had experience with KT. Common facilitators included motivated faculty (57%) and dedicated personnel (40%). Funding (60%), training (37%), and time (37%) were the most frequently reported barriers. In the adjusted model, age, gender, country, and professional focus were significantly associated with at least one factor. Prior experience with KT was significantly and positively (OR = 9.07; CI: 1.60-51.58; p < 0.05) associated with the overall KT readiness to conduct KT. Different KT readiness factors are relevant for younger (institutional climate) vs. older (self-efficacy) academic professionals, suggesting value in cross-generational collaborations. Leadership and gender were both relevant for organizational change efficacy indicating a need to engage leaders and promote women to influence organizational change. Institutions in different countries may be at different stages of change; readiness assessments can be used to systematically identify needs and develop targeted strategies.

Manjkavost liberalnog nacionalizma kao uslova pozitivnog mira na Balkanu

The subject of the paper is liberal nationalism as the only acceptable form of nationalism for the Balkans, which has been imposed and allowed by the so-called great forces (the EU and the USA) after the end of the Cold War for this, from a political and ethnic aspect, unstable region. Liberal nationalism is an integral part of liberal peacebuilding, a dominant matrix on a global level, and it has been established as one of its strategies for building and maintaining positive peace, the conditions of normal functioning and the path of the Balkan countries towards the European Union. The paper first explains the concept of positive peace and provides an overview of the state in our region, and then it points to the central ideas of liberalism and nationalism as the foundations of liberal nationalism, whose features are stated thereafter. The focus of the paper is on the analysis of the shortcomings of liberal nationalism since political and ethnic crises in the Balkan countries in the last decade indicate that, in the imposed basis of peace in these societies, "something is not right". As the most obvious drawback of the application of liberal nationalism in the Balkans, favoring political nation model has been identified, which is contrary to the history and specificities of Balkan peoples (it resulted in the projects such as the building of the so-called Bosnian and Montenegrin nation, which has deepened ethnic-identity conflicts as the basis of political crises endangering the functioning of these states). In the concluding remarks, as a basic way to solve this drawback, or rather the illogicality, of liberal nationalism as a condition for positive peace in our region, focusing and returning to the cultural model of the nation is proposed because, firstly, this is the authentic feature of this type of nationalism, which is in accordance with its origin and characteristics, and secondly, the cultural-ethnic determination of the nation is the prevailing and authentic model of the nation in the Balkans. This idea about emphasizing the primary status of a cultural version of a nation refers to the aspect of liberal nationalism on the necessity of including national belonging, as an integral part of cultural belonging, in primary goods that the state ensures for its citizens, which means that liberal state cannot be fully ethnically neutral either. Furthermore, the cultural nation model, as an autochthonous feature of Balkan peoples, needs to be included more intensively in all the segments of liberal peacebuilding, whereby its adverse effects would be mitigated in the Balkans at least in part.

Nucleic acid sensing Toll-like receptors 3 and 9 play complementary roles in the development of bacteremia after nasal colonization associated with influenza co-infection.

Streptococcus pneumoniae can cause mortality in infant, elderly, and immunocompromised individuals owing to invasion of bacteria to the lungs, the brain, and the blood. In building strategies against invasive infections, it is important to achieve greater understanding of how the pneumococci are able to survive in the host. Toll-like receptors (TLRs), critically important components in the innate immune system, have roles in various stages of the development of infectious diseases. Endosomal TLRs recognize nucleic acids of the pathogen, but the impact on the pneumococcal diseases of immune responses from signaling them remains unclear. To investigate their role in nasal colonization and invasive disease with/without influenza co-infection, we established a mouse model of invasive pneumococcal diseases directly developing from nasal colonization. TLR9 KO mice had bacteremia more frequently than wildtype in the pneumococcal mono-infection model, while the occurrence of bacteremia was higher among TLR3 KO mice after infection with influenza in advance of pneumococcal inoculation. All TLR KO strains showed poorer survival than wildtype after the mice had bacteremia. The specific and protective role of TLR3 and TLR9 was shown in developing bacteremia with/without influenza co-infection respectively, and all nucleic sensing TLRs would contribute equally to protecting sepsis after bacteremia.

THE ISSUE OF NATION-BUILDING IN INDEPENDENT KAZAKHSTAN IN THE WORKS OF DOMESTIC SCIENTISTS: A POLITICAL ANALYSIS

in this paper Kazakh researches literature review conducted on the topic of nation building in Kazakhstan. Based on articles, books and monographs published in «Bulletin of the L.N. Gumilyov Eurasian National University», «Journal of Philosophy, Culture and Political Science» of the al-Farabi Kazakh National University, «Kazakhstan-Spectr» of the Kazakhstan Institute for Strategic Studies under the President of the Republic of Kazakhstan, and e-library of the L.N. Gumilyov Eurasian National University. The purpose of the article is to identify issues of nation-building that have not been considered by Kazakh scientists. The results of the article will serve as the basis for further and in-depth study of aspects of nation building in Kazakhstan. This article provides an overview of studies of kazakh scientists dedicated to issues of nation-building in the period after the country gained independence. The work highlights the diversity of aspects associated with the formation of national identity, including both the state-forming ethnic group (Kazakhs) and other ethnic groups living in Kazakhstan. The focus of research in the early 90s was the formation of nations around national identity. In the following years scientists paid attention to the strategies of nation building - civil or ethnic, as well as the influence of the Internet, globalization and ideology through the education system. Noted that different researchers have identified different aspects, such as strengthening the Kazakh language and economic development as key elements of nation-building. However, in the reviewed works not all aspects supported by empirical data, and the vastness of the topic makes it difficult to formulate specific conclusions. Some studies rely on regulations and government programs that, which creates difficulties in assessing the nation-building process. In conclusion, it is emphasized that in the 90s a new stage of research into nation-building began in post-Soviet countries, including Kazakhstan. Despite the extensive study of certain aspects, questions remain unresolved about the formation of a nation, the role of the state language, the interest of other ethnic groups in the language, the impact of the education system and the development of the film industry on national identity.

The Impact of Media Representation on Female Athlete Identity and Self-Perception

Objective: This study explores the impact of media representation on female athlete identity and self-perception. Methods and Materials: A qualitative research design was employed, utilizing semi-structured interviews to collect data. Twenty-four female athletes, aged 18 to 35, from various sports disciplines in Istanbul participated. The interviews, conducted in Turkish, lasted between 60 to 90 minutes and were transcribed verbatim. Thematic analysis was performed using NVivo software, allowing for the identification of key themes and subthemes related to media representation, identity construction, self-perception, and coping mechanisms. The study continued data collection until theoretical saturation was achieved. Findings: Thematic analysis revealed four main themes: media representation, identity construction, self-perception, and coping mechanisms. Participants reported stereotypical portrayals emphasizing physical appearance and emotional attributes over athletic skills. Media visibility was significantly lower for female athletes compared to their male counterparts, impacting their professional identity and opportunities. The internalization of stereotypes and media-driven body ideals affected their self-esteem and body image, contributing to performance anxiety and mental health challenges. Participants employed various coping mechanisms, including resilience building, support networks, media literacy, advocacy, and personal strategies, to manage the negative impacts of media representation. Conclusion: Media representation profoundly influences female athletes' identity and self-perception, often reinforcing stereotypes and cultural biases. Equitable media coverage focusing on athletic achievements and personal stories is crucial for fostering positive self-identity among female athletes. Practical steps, including media training, advocacy, and promoting media literacy, are essential to create a more inclusive and supportive media environment.

The analysis of occupants' thermal comfort in a residential building in Tangier, Morocco

Bioclimatic design is currently one of the most important steps in passive building design adapted to outdoor climatic conditions. However, the Moroccan Thermal Building Regulations (RTCM) primarily focus on the building envelope and its energy performance, often overlooking occupant comfort. To address this gap, a bioclimatic analysis of the Mediterranean climate in Tangier was conducted to determine the percentage of thermal comfort naturally provided by this climate and to identify suitable passive strategies for buildings in the region. The results indicate that Tangier's climate can provide up to 28% thermal comfort. Consequently, the most effective passive strategies for buildings in Tangier include shading techniques, high thermal mass, internal heat gains, and direct passive heating. Furthermore, implementing these strategies can enhance occupant comfort by 6% and reduce the building's energy demand by 11.74%.

Harnessing the characteristic of compound parabolic concentrators for directional concentration of emitted thermal radiation and solar shielding in building-integrated radiative cooling

Radiative sky cooling (RC) is a promising solution for meeting the growing cooling demands by passively dissipating waste heat into frigid outer space. However, current RC systems suffer from low cooling power density and limited installation flexibility, impeding their effective application as building cooling strategies. To overcome these challenges, a novel concentrated RC system coupled with a compound parabolic concentrator (CPC) is proposed and experimentally studied. The objective is to investigate the effectiveness of the CPC in enhancing the cooling capability of the RC system and the feasibility of achieving all-day RC in unfavorable working conditions when integrated with building roofs. During nighttime experiments in the humid Nottingham region, the CPC-RC system exhibited an average emitter temperature that was 5.83 °C lower than the ambient temperature, representing a 30 % and 13.6 % improvement in RC performance compared to the flat-RC system and trapezoidal-concentrated RC system, respectively. The Photopia optical software simulation indicates that when the modules are tilted to the north, the CPC functions as a solar shield, effectively limiting solar radiation reaching the emitter surface, which is advantageous for conducting daytime RC experiments. In the daytime experiment, the emitter temperature of the CPC-RC module in anti-sunward group was still 1.59 °C lower than the ambient temperature and 5.49 °C lower than that of flat-RC module. At night, the CPC-RC module of the three placement groups all showed the highest RC effect in the same group. The average emitter temperature of the CPC-RC module in the horizontal placement group is 0.6 °C lower than that of the flat RC module. This novel CPC-RC scheme presents a new energy-saving strategy for buildings and showcases its potential for achieving 24-hour RC when integrated into anti-sunward roofs.

Development of a Green Building Assessment System at The Green Building Planning Stage in Indonesia

The fact that more people are living in cities is an important challenge for the construction industry in designing and developing cities. This industry emphasizes to have sustainable construction development principles, one of which is Green Building strategies. Because of this, several developed countries have implemented Green Building Rating Systems (GBRS) to assess Green Building achievements. Green Building Rating Systems were developed to help professionals measure building performance, and meet the requirements of sustainable design and construction. In Indonesia, there are 2 assessment standards as a Green Building Rating System, namely PUPR Ministerial Regulation No. 21 of 2021 which is a regulation issued by the Ministry of PUPR as the Ministry in charge of Public Works and Public Housing Affairs in this case includes buildings and GREENSHIP as a product of the Green Building Council Indonesia (GBCI), which is a independent institution. Different GBRS have similar objectives such as verifying the environmental performance of buildings, using natural resources efficiently, estimating the energy performance of buildings, and encouraging more energy-efficient building designs. The purpose of this research is to identify Green Building variables that are most suitable and relevant to the current conditions in Indonesia with a comparative analysis.
