Globally, buildings contribute to about 30% of total energy demand, with over half of this consumption in Canada attributed to space heating and cooling. This presents an opportunity for substantial energy and cost savings. Many buildings are transitioning to electric heating for efficiency and cost-effectiveness, but different tariff structures can result in unexpected cost increases, necessitating adjustments to the building's regular operational patterns to mitigate expenses. This study employs a building energy model developed with the OpenStudio application to conduct a comparative analysis, focusing on the impact of various tariff structures using the MUN CSF building as the case study. It investigates the impact of transitioning from a flat-rate tariff to a time-of-use tariff on energy costs, even with the adoption of energy-efficient electric resistive heating compared to the current oil-fired hot water boiler. The findings indicate that the retrofit, which proves cost-effective under a flat-rate tariff, might not yield financial savings and could potentially increase energy costs under a time-of-use tariff. The simulation results show an energy cost of CA$1,029,089 under the flat-rate tariff, derived from historical data, and CA$1,980,110 under the time-of-use tariff, based on current tariffs in Newfoundland and Ontario. This suggests that energy costs under the time-of-use tariff can nearly double compared to the flat-rate tariff, with the same amount of energy consumed and a similar usage pattern.

In hot, arid climates, educational buildings often face the challenge of limited outdoor space usage. This research, through comprehensive simulation, aims to propose practical solutions to enhance outdoor thermal comfort, particularly during school break times and student dismissal periods, thereby fostering more comfortable and functional outdoor school environments. That will happen through achieving the main objective of the study, which is evaluating the suggested passive strategies. Riyadh was selected as the case study, and four representative schools were analyzed through simulation and optimization processes to identify key areas for improvement. The research leveraged simulation tools such as Ladybug and Grasshopper in Rhino, highlighting the practicality and impact of this approach. Simulations were performed to assess the existing outdoor thermal conditions using the universal thermal climate index (UTCI) and to pinpoint regions with elevated thermal discomfort. Passive design interventions, such as shading devices and vegetation, were explored and optimized using the Galapagos in Grasshopper. This methodology supports the originality of this research in its integration of simulation tools, such as Ladybug and Grasshopper, with optimization techniques using the Galapagos plugin, specifically applied to the unique site-specific context of educational outdoor environments in a hot, dry climate in Riyadh. Additionally, insights for urban planners and architects demonstrate the possibility of integrating passive design principles to improve the usability and sustainability of outdoor spaces. The findings indicated that fewer apertures in shade devices combined with greater tree canopies might double the effectivity in lowering UTCI values, thereby enhancing thermal comfort, especially during peak summer months.

Many countries are keen to enhance existing learning spaces beyond the status quo, as nontraditional learning spaces can be leveraged to cultivate talent and ability in the 21st century. Recently, many primary schools have begun to practice planning and constructing nontraditional learning. This review highlights the available evidence on the considerations, challenges, and existing learning space design guidelines based on primary-school research conducted from 2000 to January 2024. The Web of Science (WoS) and Scopus databases are intensively searched for research conducted in primary school settings in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The finding shows optimism regarding non-traditional learning spaces fostering more flexible, innovative, and open learning environments that support and assist studentcentred pedagogical approaches, and it summarises the three results from the seven aspects. The primary considerations are physical space and pedagogical organisational design, challenges from users and designers and current research and guidelines for users and designers. Based on the three study results, this research proposes suggestions for physical learning spaces. There is an urgent need to design guidelines to promote primary school learning efficiency and create an environment that students and teachers like. [ABSTRACT FROM AUTHOR]

The buildings in various geographical conditions are strengthened due to different reasons, such as earthquakes, fire, or deterioration. One of the important issues is that comfort levels are ensured, and energy consumption is kept at a minimum in educational buildings where renovation and strengthening work is being carried out. In this study, in terms of energy consumption and acoustic comfort, a method is proposed to examine a building damaged in an earthquake and then strengthened. The method has also been created and implemented to provide control and improvement suggestions in terms of thermal and acoustic conditions in strengthening projects of buildings. As a case study, the pre- and post-reinforcement situation of an educational building in a temperate humid climate has been evaluated. In addition, different glazing scenarios that reduce energy consumption while increasing facade noise reduction have been developed and analyzed. The results showed that while sufficient noise reduction is achieved in the building envelope, there is a 15.9% reduction in the total energy consumption of the building. The optimum scenario decreased total energy consumption by 19.4 % in B113 and 26 % in B114 and increased the facade noise reduction levels by 14.2 dB in B113 and 15 dB in B114. The proposed method and the findings will contribute to the design process of newly designed, renovated, and strengthened buildings in terms of energy efficiency and indoor acoustical comfort.

Statistics indicate that cases of multiple sclerosis (MS), which can cause mobility and sensory disabilities, are increasing worldwide. While design criteria for educational built environments that meet MS students' needs have been researched, the creation of holistic design guidelines (DG-MS) has rarely been investigated. This study uses holistic DG-MS to create an educational building performance assessment tool (MS-BPAT) to evaluate the suitability of educational built environments for meeting MS students' needs. A multimethodological approach is used in which academic and medical experts evaluate the MS-BPAT for its importance, affiliation, and clarity. The MS-BPAT is then tested by assessing two high school buildings in Dammam, Kingdom of Saudi Arabia. The results indicate that the MS-BPAT tool can accurately assess the fulfillment of MS-DG design criteria in educational built environments and detect the design barriers. The MS-BPAT's validity as an assessment tool is confirmed by comparing its results with field visits, interviews, and student satisfaction. The MS-BPAT is then finalized, and recommendations are made for improving educational built environment performance to meet the needs of students with MS. [ABSTRACT FROM AUTHOR]

The study uses four AC technologies to assess the energy performance—this is a case study of an educational building in Barranquilla, Colombia. The building currently has split AC technology high-energy consumers. Therefore, it was necessary to assess a replacement with more efficient technology. Because of the non-seasonal climate in the building location, one month of monitoring of energy consumption was the reference for developing an energy model for the building using EnergyPlus and DesignBuilder software. The model was applied to forecast the building energy performance of our more efficient AC technologies available in the Colombian market, and valuable according to building specifications (Split, VRF, VAV, and Chiller). Results show a reduction in energy consumption of approximately 30% with the technology change and 15% savings in life cycle costs (LCCs), even though the building is already considered to have a low energy consumption according to national regulations. The findings of this study underscore the potential for widespread applicability across all types of buildings, regardless of their energy consumption profile, be it low, medium, or high. This extensive applicability not only highlights the adaptability and versatility of the technology but also underscores its significance in achieving substantial energy savings and cost reductions across the entire building industry, contributing to a more sustainable and economically efficient future.

This paper presents the fire load data in educational, office and library buildings, obtained through an extensive inventory survey. This data collection effort is prompted by a growing need to simulate compartment fires, wherein estimating realistic fire scenarios is essential to assess the level of fire severity in a structure, and consequently the strength of the various structural members at elevated temperatures. The attributes of compartment fires primarily depend upon the fuel load and its composition, compartment dimensions, ventilation characteristics, and construction materials. Despite an acute need, fire load data across the world is scarce and outdated, and does not reflect the change in the type of materials in‐use today. The survey data presented in this paper is collected from 108 rooms in 10 educational buildings, 51 rooms in three office buildings, and 13 rooms in a library building. This paper also presents the composition of fire loads and the levels of ventilation in these buildings. The studies show that fire loads can vary significantly depending on the room‐use; thereby basing fire load values solely on the overall category of a building may result in either conservative or unsafe design. This study also finds that certain room types (e.g., computer labs) have significant plastic‐based fuels, indicating that typical modelling recommendations based on cellulosic fuels for heat release rate, combustion heat, etc. may not always be appropriate. The paper finally examines the statistical distribution that best describes the measured values of the fire load densities. [ABSTRACT FROM AUTHOR]

School outdoor spaces are important for students as they impact learning outcomes, physical and mental health, social interaction, and overall well-being. In hot, arid climates, the use of outdoor spaces becomes a challenge. The high levels of thermal stress impact outdoor thermal comfort during the warmer months, leading to limited or no use of those spaces. This paper assesses vegetation as a passive cooling strategy for an elementary public school in the city of Riyadh, Saudi Arabia. Air temperature (Ta), mean radiant temperature (Tmrt), and Universal Thermal Climate Index (UTCI) are used to investigate outdoor thermal comfort. The experimental approach adopted in this study compares a base model against eight scenarios, which simulate different vegetation (grass, shrubs, two trees at two different heights, 5-10 m) and spacing between them (3.5 m and 7 m). The data is simulated using Envi-Met 5.5 and assessed for their impact on thermal stress levels for the school outdoor space. The results found that by applying trees 10 m high with 3.5 m spacing between them and using evergreen type leaves, Ta was reduced between (1.4-3.2)°C reaching max reduction in August, Tmrt (7.13-64.73)°C where max reduction was recorded in October, and UTCI at (3.00-17.95)°C in April. Therefore, the study offers solutions for existing schools or future ones to enhance outdoor thermal comfort.

Developing Green Walls (GW) within the architectural realm involves integration of diverse functions to optimize the indoor performance of the GW, and outdoor in campus buildings. The methodology is fundamentally rooted in the selection and fulfillment of strategic incorporation of additional function-based GW design to various performance aspects through contextual design solutions. This approach is particularly crucial in the education sector, on utilizing GW to educate students as occupants in integrating gardening, ecology, botany, and beyond in their studies for decreasing the environmental pollution for new generations, to feel by environment indoor in accomplishing way for sustainability perceptions.The aim of the study is to assess the effective resources influencing vertical green walls needed for educational buildings to reduce the effect of indoor heat, to upgrade its air quality, simultaneously decreasing noise pollution to avoid the energy consumption. The Educational GW should be accessible easily, either by installing them naturally in accessible locations with appropriate heights or by designing the facilities to increase the student's integration with GW natural environment that will reflect on their academic progress and health. The study aims to assess the effect of green wall installation in the universities of Canada in Egypt campus in the heat gain reduction, energy consumption, CO2 emission reduction by using the Design-Builder simulation program to measure the effect of green wall installation in corridors and inner courtyard at the hottest period of the year (August 2:00 p.m.) and how it can decrease the cooling loads by 10.95 %:19.14 %, heating loads by 4.8 %:12.94 %, CO2 emission by 13 %:28.43 % and the monthly electricity bill by 35:41.5 % measuring the vertical greening cost in relative to short and long period as a needed sustainable technology to reduce building demand significantly.

Building retrofit procedures play a crucial role in improving the energy performance and economic indicators of a building. In this context, an energy audit is typically recommended, but it is seldom used as a comprehensive approach due to the complexity and associated costs. This article aims to conduct a holistic energy audit approach for a university building in Malaysia, with the objective of diagnosing energy efficiency deficiencies, identifying areas of energy waste and proposing practical retrofit measures accordingly. The approach involved multiple stages, including measurements, surveys and simulation work. Eight energy-saving measures were proposed, targeting improvements in envelope elements, cooling and lighting systems, and operation and control. The Design-Builder software was utilized for energy simulation, assessing the annual energy savings. Economic evaluation indices, such as net present value and simple payback period, were used to assess the economic feasibility of the measures. The results demonstrated significant potential for energy reduction, with each measure achieving annual energy reductions ranging from 2% to 18%, and a cumulative impact of 41% on annual energy consumption when combined. The investment payback period for the energy-saving measures varied from 0.8 to 8.9 years, with a payback period of 3.9 years for the combined energy-saving measures. Furthermore, the net present value was positive, indicating the economic feasibility of investing in the proposed energy-saving measures. These findings provide valuable energy-saving opportunities that can be applied to improve similar buildings on the university campus. [ABSTRACT FROM AUTHOR]

This paper evaluates natural ventilation effectiveness in one fully dependent Air Conditioned-Educational Building in Depok to recommend potential passive cooling approaches toward user thermal comfort. This study involves building surveys to measure the temperature and humidity of three selected classrooms, A, B, and C, with varying configurations and capacities. Airflow simulation using Computational Fluid Dynamics (CFD) is done under two conditions: open and closed doors. A set of parameters, which are room configuration, type of window, and ventilation strategy, are set to evaluate natural ventilation aspects. The site survey indicates that only one classroom with an area of 92 sqm facing to the southside is classified as efficiently warm (Room A). The simulation demonstrates that cross-ventilation only occurs when the door is opened. The parameters indicating shape, dimension, type, and area of natural ventilation matter, show that the building’s natural ventilation is ineffective in providing thermal comfort. This study recommends that the building’s natural ventilation be placed according to the direction of the airflow, adding vertical fin elements, and increasing the openings by more than 5% area from the floor area.

The B building sector contributes to 40% of the carbon emissions in the atmosphere. Several studies show that high-performance MAN (Madrasah Aliyah Negeri) buildings contribute to reducing carbon emissions. This study discusses the evaluation of natural lighting in educational buildings, namely the MAN (Madrasah Aliyah Negeri) Cimahi building. This research was conducted using direct survey methods via measuring and simulating the natural lighting using Sefaira. The simulation results show that natural lighting in the building does not meet lumination standards. This article concludes that the addition of a roof overhang, windowed areas, façade elements, and shading strategies are all factors that can affect natural lighting in the MAN (Madrasah Aliyah Negeri) Cimahi building.

Design decisions are usually dominated by concern for economic and material aspects, and neglect or omission of social and human aspects (human behavior), Thus, the needs and requirements of the individual users (basic education students) are ignored. This completely contradicts the views of the users of those spaces, as well as specialists in the field of psychology and sociology, about the role of design processes in achieving a suitable physical environment for the human behavior of the users of those spaces (the school building). Ignoring the requirements of the users on the one hand, and the behaviors of the users on the other hand creates an inefficient, and unfulfilled vacuum for the aesthetic, social, cultural, economic, and recreational goals. It is necessary to know the requirements needs, and behaviors of students to achieve successful spaces, as it is the main factor in the success of school buildings, given that the human being affects and is affected by the physical environment. From this standpoint, it is clear that urban designers should pay attention to the process of designing school buildings from a perspective based on behavioral human considerations, and there is a need to integrate studies of the physical environment with human studies (human behavior) in designing spaces to achieve the physical and moral functions of those spaces. educational environments affect the creation of a psychological atmosphere conducive to educating students and encouraging them to be creative, and are considered a strong basis in preparing a conscious generation that helps the renaissance and progress of society. Hence the need to pay attention to this environment (represented by educational spaces), which has become the basis for the development of the architectural educational environment, which is part of the educational and educational development. Many studies were conducted to find out the relationship between the behavioral problems of students and the geometric spaces of the educational building. Therefore, many researchers stressed the need to develop the engineering spaces of the educational building and to pay attention to their implementation and development in line with the needs of the times to produce more attractive schools for students. In light of this, the research problem was determined in the need to know the effect of interior design on students' behavior, achievement and scientific performance.

Heritage architecture, which considers the local climate, building materials, and construction methods, can contribute to the energy efficiency and sustainability of buildings. Retrofitting strategies can be applied to existing buildings to improve their energy performance while maintaining or enhancing their thermal comfort. This study involved an analysis of the indoor environment status at the Yonsei University Stimson Hall (completed in 1920), a building on the former Yonhee College (now Yonsei University). The analysis included temperature and humidity measurements over a one-year period in four rooms with different usage schedules and occupant types. It was found that the number of occupants and the usage schedule influenced the temperature distribution in the rooms. In addition, the effects of the retrofitting strategies on the building energy consumption were investigated. It was verified that the improvement in windows and the application of roof-type photovoltaic systems resulted in annual energy savings of up to 90.46% compared with reference buildings. In conclusion, the findings demonstrate the influence of variables such as usage schedule, occupant type, and season on the indoor climate, as well as the potential benefits and drawbacks of retrofitting strategies on energy consumption and thermal comfort.

The development of digital twins leads to the pathway toward intelligent buildings. Today, the overwhelming rate of data in buildings carries a high amount of information that can provide an opportunity for a digital representation of the buildings and energy optimization strategies in the Heating, Ventilation, and Air Conditioning (HVAC) systems. To implement a successful energy management strategy in a building, a data-driven approach should accurately forecast the HVAC features, in particular the indoor temperatures. Accurate predictions not only increase thermal comfort levels, but also play a crucial role in saving energy consumption. This study aims to investigate the capabilities of data-driven approaches and the development of a model for predicting indoor temperatures. A case study of an educational building is considered to forecast indoor temperatures using machine learning and deep learning algorithms. The algorithms' performance is evaluated and compared. The important model parameters are sorted out before choosing the best architecture. Considering real data, prediction models are created for indoor temperatures. The results reveal that all the investigated models are successful in predicting indoor temperatures. Hence, the proposed deep neural network model obtained the highest accuracy with an average RMSE of 0.16 °C, which renders it the best candidate for the development of a digital twin.

There are various factors that can cause the rise of Neutral-To-Ground Voltage (NTGV) in an educational building. However, based on the pattern of the recorded NTGV, it is difficult to identify the possible factors that contributed to the event. This situation could lead to the wrong decisions to mitigate the corresponding problem. Thus, the main objective of this paper is to verify the high NTGV events based on a model of the educational building's three-phase fourwire system. In this study, the developed educational building electrical network model is integrated with the model for events in a MATLAB/SIMULINK environment. According to the findings, high NTGV events in the building were caused by lightning and ground fault activities. This shows that the model is accurate and suitable to be used for analysing the high NTGV events in an educational building if they are detected. [ABSTRACT FROM AUTHOR]

Building occupancy patterns are an important factor in considering the energy efficiency of buildings and a key input for building performance modelling. More specifically, the energy consumption associated with heating, cooling, lighting, and plug load usage depends on the number of occupants in a building. Identifying occupancy patterns and profiles in buildings is a key factor for the optimisation of building operating systems and can potentially reduce the performance gap between the planning stage and the actual energy usage. This study aims to identify the patterns and profiles of the occupants in a selected case study building in England. In this study, occupancy data were collected over 12 months at five minutes intervals. A sensor was used to obtain high accuracy occupancy data compared to previous studies that encountered uncertainties in data collection. A set of clustering analyses was carried out to identify occupancy patterns and profiles in the building. The results of this study identified three different occupancy patterns and profiles as well as four drivers that influenced the occupants in the case study building: the beginning of the academic term, the examination period, the weekday/weekends, and the vacation driver.

This study aimed to analyze the spatial perception of educational buildings with historical significance by users. In this context, Antalya Vocational and Technical Anatolian High School, which is a historical building, was discussed as a material. A questionnaire was applied to individuals who graduated from this high school to examine how the facade design and garden layout were perceived in the spatial evaluation of the high school discussed in the study. Three different facade designs (modern, traditional, and mixed) based on the building complex were prepared using the AutoCAD, 3D Max, and Photoshop CS3 programs to be used in the questionnaire form consisting of open-ended and closed-ended questions. The frequency analysis was performed using the SPSS program to evaluate the data obtained after the questionnaire. According to the obtained results, it was determined that the middle age group was highly interested in the traditional and mixed facade design. It was observed that the participants further preferred the modern facade design as their level of education increased. It was observed that the participants preferred the mixed facade design more as their income level increased. Furthermore, it was determined that the mixed facade design was generally preferred more by the participants. In conclusion, the quality of historical buildings from the past should be updated with a modern perspective. Thus, positive effects will be achieved for the continuity of the building and its compliance with the environment. It is foreseen to provide positive effects both in terms of functionality and in the field of visual admiration and comfort by evaluating the changing needs of society over time and environmental factors together. On the other hand, while positive elements ensure the continuity of buildings and building complexes, it will also be possible to contribute to their becoming an urban image.

This study aims to reduce the lighting energy consumption in educational buildings while avoiding an increase in cooling load. The Faculty of Engineering building in Universitas Indonesia, Depok, West Java, Indonesia is used as a case study. Daylight optimization can have an impact on lighting energy, which is the largest energy consumer in educational buildings. However, given Indonesia's tropical climate, daylight leading to heat gain is a concern. Current passive design interventions for controlling daylight and heat gain include light shelves, clerestories, and glazing materials. Daylighting performance is simulated using DIALux software. Results of each intervention are analyzed quantitatively and qualitatively by theories and parameters, namely illuminance level, light uniformity, and overall thermal transfer value (OTTV). Light shelves result in increased uniformity and lower OTTV. Clerestories result in increased average illuminance but higher OTTV. Active intervention with a dimming and grouping system is applied after daylight increases. The combination of passive design interventions and active dimming of electric lights reduces lighting energy with the same OTTV as existing. This study recommends the use of passive and active daylighting strategies considering their effect on the cooling load of buildings. [ABSTRACT FROM AUTHOR]

Summary: In this research, an integrated energy system for providing triple loads of an educational building has been modeled, analyzed, and optimized using artificial intelligence The use of different load supply patterns for the integrated system was optimized and evaluated from the point of view of exergy, economics, and environment. SketchUp, OpenStudio, and EnergyPlus are used to obtain the building loads, and the integrated system is dynamically modeled by the MATLAB software. The integrated system has been optimized based on different patterns, including monthly, seasonal, and two‐state constant loads compared with hourly dynamic loads using an artificial intelligence genetic algorithm. The results show that the dynamic load pattern gives the highest exergy efficiency and the lowest total cost rate. The exergy efficiency and total cost rate in this scenario are 58.78% and 5.022 $/h, respectively. Also, the CO2 emission index has reached 363.1 g/kWh. Due to the subsidized price of grid electricity, there is a tendency to use low‐capacity gas turbines and buy electricity from the grid for the dynamic model. The gas turbine capacity is 35.56 kW, and the system has purchased 242.4 MWh from the grid. Due to high heating loads, the capacity of the gas turbine significantly increases, and no electricity is purchased from the grid in the fixed‐load pattern. The highest capacity of the gas turbine is 161.6 kW, which is obtained by a seasonal fixed‐load pattern. Also, 994.9 MWh of electricity is sold to the grid in this mode. [ABSTRACT FROM AUTHOR]

The school built environment is closely related to children's health, and research on this topic is increasing. However, bibliometric analyses seeking to provide a comprehensive understanding of the research landscape and key themes in the field are lacking. This study comprehensively explored the global trends and research hotspots on the associations between school built environment and children's health. We used a scientometric analysis to review the research progress. The temporal distribution of publications, scientific collaborations, research hotspots, research frontiers, and co-citations over the past 30 years were analyzed. The results show that the number of publications in this field rose significantly between 1987 and 2025, with research hotspots focusing on physical activity, performance, behavior, perception, thermal comfort, and indoor air quality. Environmental themes related to children's health fall into four main groups: the built environment related to children's activities, intelligent learning environments, indoor environments and interiors, and natural environments. Health outcomes and measures that reflect physiological, psychological, cognitive, behavioral, and physical factors are discussed. This study provides a broad understanding of research issues and trends related to the school built environment and children's health., (© 2025 Walter de Gruyter GmbH, Berlin/Boston.)

Currently, thermal comfort and indoor air quality are essential elements in designing modern and intelligent buildings or improving existing ones, so that they would provide proper indoor conditions. The article focuses on the thermal sensations of the students of Kielce University of Technology and determining whether the given parameters of the internal environment contributed to their well-being. 164 people aged 16 - 24 participated in the study, which was conducted with the use of a microclimate meter and questionnaires. It turned out that the temperature range from 19.3 °C – 27.6 °C is acceptable and comfortable for nearly 78% of people. As a result of further analysis, it turned out that the research group definitely prefers and feels better in colder temperatures.

The B building sector contributes to 40% of the carbon emissions in the atmosphere. Several studies show that high-performance MAN (Madrasah Aliyah Negeri) buildings contribute to reducing carbon emissions. This study discusses the evaluation of natural lighting in educational buildings, namely the MAN (Madrasah Aliyah Negeri) Cimahi building. This research was conducted using direct survey methods via measuring and simulating the natural lighting using Sefaira. The simulation results show that natural lighting in the building does not meet lumination standards. This article concludes that the addition of a roof overhang, windowed areas, façade elements, and shading strategies are all factors that can affect natural lighting in the MAN (Madrasah Aliyah Negeri) Cimahi building.

Earth-to-air heat exchangers (EAHEs) are widely used to reduce the indoor temperature and associated cooling energy demand of buildings. This study investigated the potential reduction in indoor temperatures via energy-efficient ventilation through EAHEs in an existing architectural campus building (ACB) with an energy-efficient renovated building envelope in the hot and humid climate of Karachi, Pakistan. The building information modeling (BIM) program Autodesk Revit was used to develop a virtual ACB BIM model. An EnergyPlus parametric analysis of the ACB BIM model in DesignBuilder facilitated quantification of the influences of operating parameters such as pipe installation depth and pipe diameter for EAHEs with similar total pipe lengths and air-exchange rates on the performance of the EAHEs during the cooling season. A 3 m deep and 0.1 m diameter pipe layout in open space significantly reduces indoor temperature via a specific duct layout in an exemplary ACB. The results show that a pipe diameter above 0.1 m is unsuitable because of the reduction in convective heat transfer due to the increase in the pipe's surface area and the decrease in pressure in the pipe. The findings of this study can be used to improve the indoor thermal comfort of buildings in climates with comparable properties. [ABSTRACT FROM AUTHOR]

Schools are nearly a living organism which supports future generations, abilities and leaders, and enables our communities to improve. Even though their major purpose is to provide students with a good education, school structures and campuses ensure a number of social duties and functions. While there are 18 million 241 thousand 881 students at the primary and secondary education level in Turkey in 2019-2020 school year, there are 1 million 117 thousand 686 teachers (Hürriyet, 2020). Primary and secondary school buildings more than 68 thousand 589 in Turkey were closed during the pandemic, and all the students attended the educational activities from their homes (Hürriyet, 2020). Educators' continuation for teaching students was ensured by such innovations as distance education. However, the impediments to distance education have increased socioeconomic inequalities. Access to distance education has become dependent on technological tools, including internet infrastructure ownership, computer-tablet availability. In some homes, students completed their schoolwork, sometimes sharing smart devices among siblings. The fact that students go to school does not only support their education but also improves them physically, mentally and socially. For all these reasons, it is crucial to start finding a way to reopen schools in a safe and measured way. Although distance education will continue in some way after the schools are reopened, getting back to the classroom (even in a limited way) is critical to the emotional and mental well-being of students. Even though the curriculum plays an important role in preparing children for success as adults, problem solving, coming together, communicating, producing collaborative work, social relationships and interpersonal experiences are also very important for childhood development. Many students missed reconnecting with their friends and teachers and sharing experiences such as classroom trips and graduation ceremonies. Reopening of schools under pandemic conditions is a difficult and complex decision that must be broken down into manageable pieces. Actions to be taken today in response to the COVID-19 pandemic will lay the groundwork for the proactive, long-term preparation needed to ensure that schools are resistive to future disasters and pandemics, including potential flu outbreaks. This study summarizes the findings on primary education structures and provides education authorities with insight and guidance on school reopening. [ABSTRACT FROM AUTHOR]

The development of digital twins leads to the pathway toward intelligent buildings. Today, the overwhelming rate of data in buildings carries a high amount of information that can provide an opportunity for a digital representation of the buildings and energy optimization strategies in the Heating, Ventilation, and Air Conditioning (HVAC) systems. To implement a successful energy management strategy in a building, a data-driven approach should accurately forecast the HVAC features, in particular the indoor temperatures. Accurate predictions not only increase thermal comfort levels, but also play a crucial role in saving energy consumption. This study aims to investigate the capabilities of data-driven approaches and the development of a model for predicting indoor temperatures. A case study of an educational building is considered to forecast indoor temperatures using machine learning and deep learning algorithms. The algorithms’ performance is evaluated and compared. The important model parameters are sorted out before choosing the best architecture. Considering real data, prediction models are created for indoor temperatures. The results reveal that all the investigated models are successful in predicting indoor temperatures. Hence, the proposed deep neural network model obtained the highest accuracy with an average RMSE of 0.16 °C, which renders it the best candidate for the development of a digital twin.

This study explores the diurnal variations and influencing factors of PM 2.5 , NO 2 , and ozone concentrations in educational buildings. Utilizing an integrated system of indoor and outdoor sensors, building automation control networks, and walk-through inspections, air quality data along with relevant characteristics were collected from ten educational buildings in Central Florida. Advanced Neural Network models (RNNs and CNNs), including the Long Short-Term Memory (LSTM) and the Attention Temporal Convolutional Network (ATCN) algorithms based on the Least Absolute Shrinkage and Selection Operator (LASSO), were developed to accurately identify diurnal patterns in indoor air quality (IAQ) and the differences in influencing factors. The findings indicate greater variability in diurnal differences and factors influencing indoor NO 2 and ozone concentrations compared to PM 2.5. Although the factors influencing day and night PM 2.5 levels were similar, there were significant differences in the contribution weights of these factors. Optimized RNNs and CNNs significantly outperformed standard Artificial Neural Network (ANN) models in dynamically simulating and predicting target pollutants. Comparative analysis of the root-mean-square error (RMSE) demonstrated that LASSO-LSTM models comprehensively outperformed LASSO-ATCN models by averaging 13.4% (p < 0.05). These results can be referenced in studies concerning Indoor Air Quality (IAQ) control conducted in similar environmental settings. • Indoor and outdoor air pollution measurements were conducted in ten BACnet-equipped buildings. • Indoor PM 2.5 , NO 2 , and O 3 exhibited diurnal fluctuations in their influencing factors. • The D/N ratio of indoor NO 2 and its contributions from influencing factors are unstable. • LASSO-based ANNs significantly outperformed standard ANNs in simulating targeted pollutants. • LASSO-LSTM outperformed LASSO-ATCN by averaging 13.4% (p < 0.05).

As climate change concerns are rising rapidly, energy efficiency promotion and implementation could be sustainable solutions within energy transition. In this context, buildings, including educational ones, play an important role in reducing energy needs and promoting energy efficiency since they account for a significant share of the total energy consumption. As a case study for this research, the educational building of Kazakh-German University was selected. Following the national and international building standards, energy performance parameters were estimated. Current heat losses and performance have been estimated as baseline scenario settings. The impact of retrofitting measures on energy efficiency performance of the buildings under the four scenarios was calculated. Under the minor scenario, retrofitting interventions will lead to annual energy savings of 36.9 kWh/m2 and a 48% CO2 emission reduction, whereas under the major scenario, the annual energy savings will increase to 77.76 kWh/m2 and a nearly 82% CO2 emission reduction. The integration of a solar thermal system with capacity 400 kWh, assuming that the heat demand was reduced under the minor retrofitting scenario, can decrease heat energy consumption and CO2 emissions to 35%. As upfront costs of the energy efficiency measures are high, a carbon offset mechanism could facilitate the implementation of university building modernization. [ABSTRACT FROM AUTHOR]

Achieving indoor thermal comfort is essential for productivity, especially in educational environments, and hence has recently attracted considerable attention. Phase change materials (PCMs) integrated into various building components have been used to improve the indoor temperature. In this study, the effectiveness of integrating macro-encapsulated BioPCMs into the walls and ceilings of lecture halls in an educational building was determined via simulation. The simulations considered a hot climate coupled with controlled night ventilation of 15 air change per hour for enhancing the indoor temperature. Using the EnergyPlus software, simulations were performed for different PCM melting temperatures (25, 27 and 29°C) and thicknesses. The PCM with a melting temperature of 27°C yielded a notable reduction (0.5–3.3°C) in the indoor temperature. Furthermore, increasing the layer thickness to 3.75 cm had little effect on the temperature, as indicated by the incomplete charging process during the night. [ABSTRACT FROM AUTHOR]
