Numerical simulation of natural ventilation with passive cooling by diagonal solar chimneys and windcatcher and water spray system in a hot and dry climate

The overuse of fossil fuels has become a major challenge in recent decades. Since mechanical ventilation systems are responsible for the largest proportion of the energy usage in the buildings, this study aims to come up with a green initiative for resolving the dire consequences of energy consumption. Here, for the first time, we work on an approach in which we aim to assess and enhance the evaporative cooling rate of a passive method during a summer day in a multi-story building in a hot and dry climate. In this regard, the windcatcher is coupled with three solar chimneys, and a water spray system (WSS) which is located at the entrance of the windcatcher to decrease the temperature and raise the humidity of the air entering each floor. A combination of wind-catcher, solar chimney, and water spray system is adopted to provide natural air circulation in the absence of wind. Indeed, we employ Radiation, Turbulent, and Discrete Phase Models to simulate the proposed system by CFD. The effect of different variables such as temperature, droplet diameter, and thermal comfort factors are studied. Temperature, velocity, and other airflow profiles are analyzed using ANSYS FLUENT software. The study highlighted that adding WSS leads to a roughly 6–12 °C reduction in the temperature; moreover, relative humidity will rise by 80% on the third floor. Accordingly, adding WSS can improve the system’s efficiency and satisfy the thermal comfort conditions in the absence of wind.

Development of Sustainable Indoor Air Quality for Air-Conditioning System Using Smart Control Techniques

Air-conditioning as a technical solution to protect inhabitants from excessive heat exposure creates the challenge of expanding indoor health effects. While air-conditioning has mostly been applied as an improvement to living conditions, health and environmental problems associated with its use frequently occurs. Therefore, this paper challenges and extends existing knowledge on sustainability related to the smart air-conditioning systems. The decrease of CO2 level in building requires an intelligent control system because energy utilisation has been legitimately connected with wellbeing and eventually to operational expenses. A building’s indoor environmental essential factors of comfort are IAQ, visual and thermal. Through an appropriate structured controller, the performance of indoor control system can be altogether improved. It merits creating innovative control techniques to optimise the indoor environment quality for air-conditioning system. The newly proposed backpropagation neural network was optimised using Matlab to control the CO2 level appropriately while carefully taking into account the performance of system controllers such as the stability, adaptability, speed response and overshoot. The controller of indoor environment was designed, and the proportional-integral-derivative control was utilised as a result of its suitability. The smart controllers were designed to regulate the parameters automatically to ensure the optimised control output. The indoor CO2 possesses an appropriate time constant and settling time of 2.1s and 27.3s, respectively. Therefore, utilising smart control techniques to exterminate various indoor health effects is expected to produce sustainable living conditions.

Travelers’ engagement with local food at a foreign destination could be overwhelming and affect their overall travel experience. This study investigates the role travelers’ psychological comfort with local food plays in influencing the development of their place attachment to a destination. The study utilized survey data sampled from Korean and American travelers who had visited China and found that travelers’ place attachment is positively and significantly influenced by their psychological comfort with food, interaction with service providers, and atmospherics. The findings also reveal that Korean and American travelers differ in the degree to which comfort affects their place attachment. These and other findings of the study bring attention to the comfort factor of travelers’ food experience, thus complementing previous research that tended to emphasize the novelty value of local cuisines.

Analysis of Spatio-temporal patterns and related factors of thermal comfort in subtropical coastal cities based on local climate zones

"Local Climate Zone" (LCZ) is a land classification scheme for urban thermal environment, combined with the "Universal Thermal Climate Index" (UTCI) indicator that characterizes human perception of the thermal environment, which can effectively reflect human perception of the thermal environment. In order to evaluate the thermal comfort of Shenzhen in 2020, the hourly data of 65 weather stations covering 11 LCZ types are used to calculate UTCI, which is used to analyze the temporal and spatial patterns of thermal comfort and related factors. The results show that the thermal comfort of 11 types of LCZ in Shenzhen all year round conforms to the characteristics of Shenzhen's subtropical monsoon climate. The 11 types of LCZ thermal comfort are higher at night than during the day. The thermal comfort of different LCZ types is statistically significantly different. The "Built type" LCZ has a higher thermal comfort value than the "Land cover type" LCZ, and the time in the thermal level is longer. Summer thermal comfort in Shenzhen was found to be positively correlated with building surface fraction, building height, street aspect ratio, and distance to the sea, and negatively correlated with sky view factor and pervious surface fraction. In addition, the summer sea breeze has a cooling effect on the thermal comfort of the entire Shenzhen area, and the barrier-free ventilation corridor can observe a better cooling effect. The research results of this paper can provide reference for improving the thermal comfort in Shenzhen.

A novel glazing system filled with hydrogel granules: energy saving, diurnal illumination, color rendering, and co2 emission mitigation prospective

ABSTRACT Building glazing systems have a significant impact on air-conditioning loads and diurnal illumination in buildings. Incorporating thermal-insulating materials in the interspace of double-glazing is an ideal energy-efficient choice to insulate glazing for reduced air-conditioning costs with comfortable daylight factors. This paper evaluates the solar-optical, color rendering properties, thermal indices, and cost-savings potential of novel glazing systems, where the air-space of double-glazing is filled with different colored hydrogel granules (hydrogel glazing). Thermo-economic analysis was carried out with a numerical model for India’s three distinct climatic regions (Warm, Hot, and Temperate). Proposed hydrogel glazing showed a substantial heat gain/loss reduction, resulting in enhanced air-conditioning cost savings. The double glazing with orange hydrogels granules (DGOH) showed a reduction of 31.67% in summer solar heat gains for the temperate climate. The analysis had concluded net annual cost savings of 6.99 $/m2 for DGOH glazing with a payback period of 0.40 years for the temperate climate. Warm and hot climates also reported identical heat gain reductions and annual savings ($/m2). Carbon emission mitigations of building with hydrogel glazing were estimated with the help of yearly carbon emission factors. The simulated average daylight factors of model buildings with hydrogel glazing were well above the recommended levels in compliance with building codes. The assessed color rendering metrics of hydrogel glazings were satisfactory for visual acceptability in building interiors. The results of this work help engineers and architects to decide on energy-efficient glazing systems for energy-conscious buildings.

The demand in the world market for high quality fine and superfine wool is increasing, responding to greater wool textile industry demands and price incentives. There are few research studies focused on hair follicle population in fine and superfine Merino sheep in Uruguay. This study evaluates the association between wool follicle population and the most relevant economical wool traits. This work was carried out on Ultrafine Australian Merino (UAM) and Dohne Merino (DM) animals (lambs and rams). Phenotypic correlations between the secondary/primary follicles (S/P) and other wool traits (fiber diameter, staple length, clean fleece weight, scoured yield, coefficient of variation of fiber diameter and comfort factor parameter, were performed using histological skin cuts. Two skin samples were extracted from each lamb at two and nine months of age. These were processed at the skin histology laboratory to obtain a histological preparation for further biopsy, being able to differentiate the structures obtained to be evaluated. The results showed in the UAM group, S/P ratio in nine-month-old lambs was greater than two-month-old lambs (31.08 vs 23.12 P< 0.05). For DM group, there were no differences in the S/P ratio between age groups. Phenotypic correlations for wool characteristics obtained were of low to medium or null magnitude in both genotypes.

Analysis of Factors Affecting Industrial Engineering Students' Learning Interest in the Online Lecture System

The COVID-19 pandemic has forced universities, lecturers, and students to suddenly migrate from face-to-face learning to online learning. in early 2020 these three components must adapt to the situation, but after 2 semesters of adaptation had taken place, the factors that influenced students in attending online lectures are the factor of lecturers and students’ adaptability to the software used, the factor of phone signal in the area where the students live, and the factor of limited funds for data. These factors will affect the students’ comfort factor and shape their interest in the online learning system. This research used a sample of Industrial Engineering students to produce the factors that influence learning interest in the online system. From the descriptive data analysis, it reveals that students perceive lecturer adaptation to online learning as quite good, the quality of the network as tolerable, although there are areas where the internet signal is considered weak. The students’ experience of online lectures is a little less satisfactory. The highest scores of students' expectations for future teaching system are: 48% for a 50% online and 50% offline system, 75% for a pure offline system, and 25.6% for a 25% online system. The relationship between students' perceptions of the adaptability of lecturers, internet quality and their experiences of online lectures affect the student’s comfort in online lectures in the form of a linear regression.

Improvement strategies for thermal comfort of a city block based on PET Simulation— A case study of Dalian, a cold-region city in China

A block is an urban construction of land surrounded by roads and its internal buildings and environment. It is an essential element of modern cities and the most direct way to perceive the urban living environment. The thermal comfort of a block is a crucial indicator for building a healthy and comfortable urban life. This study examined Dalian, a cold-region city in China, to put forward research on thermal comfort improvement strategies. In this paper, four typical blocks were selected to simulate the microclimate by ENVI-met, and the physiological equivalent temperature (PET) was calculated. Through the simplified model, the thermal comfort building strategy suitable for Dalian was explored, and the effectiveness was verified. The results show that direct solar radiation and wind speed are the critical factors for the thermal comfort of the settlements residents. The building orientation, sunshine spacing coefficient, and building layout will affect the thermal environment of the block through these two factors. The outdoor thermal environment in Dalian can be improved by adjusting the orientation of buildings away from the traditional south direction, increasing the sunshine spacing coefficient, dislocating buildings, or adopting a peripheral-type building layout. This study can provide a scientific basis for building healthy and comfortable urban living environments and block development and renovation decisions.

Although feelings of pleasure are not defined as the main instrument in achieving performance, emotional involvement in work cannot be ignored. Invisibly, feelings dominate work attitudes and behavior, so that performance can be achieved. So paying attention to the factors of happiness and comfort at work must be considered by organizational management. This study aims to analyze the role of job satisfaction on improving performance by paying attention to the variables of communication, self-esteem, and self-efficacy. The research method uses causal associative with regression analysis techniques. In collecting data, a purposive sampling technique was used with a questionnaire as a research instrument. The results of the study indicate that satisfaction is a factor that is considered important by every employee. The reason is, work is not only a matter of making money, but as a place to interact between one person and another within the scope of business activities, then building good communication is a necessity, then having self-confidence is a capital in meeting the interests of the organization and the work environment. Statistically, the value of the contribution of the variables of communication, self-esteem, and self-efficacy is 0.162. This means that job satisfaction will increase with an estimated value of 16.2% if work communication is well developed and self-confidence is high.

Adaptive thermal comfort factors in classroom acoustics

Climate change is affecting the built environment with a growing need to balance adaptive comfort models by relating ambient room temperature and outdoor climatic factors, on the one hand, with adequate classroom acoustics, on the other hand. The adaptive approach allows occupants of a space to adjust their clothing, activity and posture in a space to minimize thermal discomfort while strategizing for adequate reverberant energy and speech clarity. A parametric digital classroom model was built and simulated to various thermal comfort conditions while simultaneously observing the reverberation times (RT) to determine how quickly sound decayed in the space. Building materials were tested parametrically with variable thermal transmittance (U-values) analyzed with corresponding changes in reverberation times. Observed outdoor environmental variables included mean monthly outdoor temperature and relative humidity. A classroom with thirty University students were observed. Measured and simulated data were analyzed for the parametric model applying scatter plot of utilizing the ASHRAE seven-point predicted mean vote (PMV), percentage people dissatisfied (PPD) and reverberation time measurements. Initial findings assessed using ANSI/ASHRAE Standard 55 indicate that occupants of a space tend to reach adaptive thermal comfort in a wider range of conditions than commonly noted but inadvertently negatively affect good classroom acoustics.

Strategy and results of managing the formation of an enabling enterprise environment in the conditions of digital transformations

Enterprises need an enabling environment to function and develop steadily. The macro level determines the comfort factors in the context of global transformations. In addition, domestic enterprises have limitations in their own funds to carry out transformations, in particular, digitalization. This was most acutely manifested in the context of the COVID-19 pandemic. In such a situation, state support for entrepreneurial structures is a driver for the formation of an enabling business environment. This is especially noticeable if it is carried out on the basis of strategic territorial management. This work is carried out in order to identify the actual results of strategic management at the regional level in the formation of an enabling environment for the enterprise functioning and development in the context of digitalization, as well as to present proposals for improving the quality of the achieved results. The research is based on the works of domestic and foreign scientists. The analysis showed the focus of the strategic management of the Republic of Crimea on the formation of an enabling enterprise environment. Currently, a system of enterprise support is being created in the region. Its various forms and types act favorably in Crimea. It is necessary to provide training of personnel with appropriate qualifications. In addition, the coordination and consistency of measures to implement the republican strategies of "Three Wins" and the digital transformation of the region, in terms of creating an enabling enterprise environment, will improve the quality of the achieved results.

ANALYSIS AND EVALUATION OF COMFORT OF HOUSING COMPLEXES (DEVELOPMENT STUDIES IN WESTERN UKRAINE)

Abstract. Architects and urban planners in the process of designing residential areas use building codes that consider the comfort of living only in terms of safety, sanitation and environmental performance. This article highlights the problem of taking into account a number of additional social parameters of comfort that affect the characteristics of living comfort. The structure of a comprehensive analysis of housing is formed by assessing the elements of living comfort. The presented research algorithm includes the consistent use of methods of sociological survey, evaluation and modeling. Having identified socio-psychological factors of comfort of a residential district at different levels of urban assessment (in the context of location in the city system, formation of the surrounding area, spatial and architectural-planning level), 3 residential development projects of Ivano-Frankivsk were assessed. For a comparative analysis, the architectural and planning solutions of residential quarters "Lemkivsky", "Club town 12", "Vidensky" were used, the construction of which began in 2017. This took into account not only the quantitative technical and economic indicators of individual elements of the project, but also qualitative indicators, the measurement of which in normal conditions is a resource-intensive process. As a result of the analysis and the carried-out estimation the graphic model of the complex analysis of a residential quarter is formed that allows to carry out comparison of various design decisions irrespective of size of a site of quantity of housing sections, etc. Using the method of movement to the ideal, a comprehensive analysis of various residential complexes was carried out. The obtained results allow, both at the stage of designing residential neighborhoods and the analysis of operated facilities to assess them in accordance with the needs of people, as well as to balance the indicators of comfort by applying the proposed architectural and planning techniques.
