Thermal Performance and Building Energy Simulation of Precast Insulation Walls in Two Climate Zones

Traditional concrete buildings exhibit low energy consumption and high heat loss, which results in a larger environmental problem. Precast insulation walls are proposed for strengthening thermal insulation efficiency and mitigating heat loss. Numerous studies have investigated the thermal performance of insulation walls over the past decades. However, gaps remain in practical engineering applications. This study aims to bridge these gaps by providing practical design recommendations based on experimental research. Nine different types of precast insulation walls were tested to examine the thermal performance, and the parameters of the insulation material, insulation form, insulation layer thickness, and concrete rib width were investigated. Then, numerical models of these walls were developed for simulating the thermal performance of the tested specimens. Finally, a six-story student apartment model using designed walls was developed to assess energy consumption in two distinct climate zones: the hot summer and cold winter zone of Changsha City, and the cold zone of Harbin City. The results indicate that the precast insulation wall with external insulation form shows better thermal performance than the sandwich insulation form. It is recommended to use precast insulation walls with 50 mm extruded polystyrene (XPS) external thermal insulation form in Changsha City and 80 mm XPS external thermal insulation form in Harbin City. Furthermore, buildings using precast insulation walls can significantly reduce energy consumption by 49.25% in Changsha and 49.38% in Harbin compared to traditional concrete wall buildings. Based on these findings, suitable design suggestions for this precast concrete wall panel building composed of insulation walls are given.

Occupants’ willingness to reduce in-room energy consumption − a discrete choice experiment (DCE) approach with occupants in a student apartment

This study pioneers a comprehensive methodology to quantify occupants’ willingness to reduce energy consumption behaviors, specifically focusing on student occupants within a student apartment under an all-inclusive payment rental scheme. Employing a dual-component approach, the study combines self-indicated energy consumption behavior attributes with the financial rebate occupants are willing to accept, shedding light on the intricate factors influencing their decisions regarding energy consumption. The Discrete Choice Experiment (DCE) serves as a novel tool to identify and measure the financial value, conceptualized as Willingness-to-Accept (WTA), for specific energy-saving behaviors, contributing to a nuanced understanding of the economic valuation placed on sustainable practices. A pre-survey and a DCE-based survey were conducted within the student apartment, the former one comprehending general energy consumption behaviour patterns and rebate preferences, and the latter examining the impact of financial incentives on behavioral changes, providing a comprehensive and longitudinal perspective. The findings highlight the paramount influence of factors such as “air conditioning setpoint” on occupants’ decisions followed by “lighting time” and “shower time”, emphasizing the delicate balance between occupant comfort, financial considerations, and environmental consciousness. Despite limitations related to the specificity of the study context and potential discrepancies between hypothetical and real-world behavior, this research offers practical implications for designing effective energy-saving interventions tailored to the unique characteristics of student occupants. Policymakers and stakeholders can leverage these insights to inform incentive structures, energy conservation initiatives, or pricing strategies that align with consumer preferences, ultimately encouraging sustainable energy practices in residential settings.

Analisis Pasar Pembangunan Apartemen Mahasiswa Institut Teknologi Sumatera

The more rapid development of the Sumatra Institute of Technology will have an impact on the demand for student housing needs. The residential rental business in the form of rented houses and boarding houses is increasing. However, there are no rental housing for students with the concept of apartments around the Sumatra Institute of Technology built by developers. Even though the target market is clear, namely students, it is necessary to do a detailed market analysis. This study aims to analyze the market for student apartment development around the Sumatra Institute of Technology. The research method used is qualitative with descriptive analysis techniques. Data on aspects of market analysis were explored through website searches, literature studies, interviews, questionnaires, site surveys and documentation. This study found that from the market analysis aspects that have been analyzed, the Sumatra Institute of Technology student apartments have the potential to be built.

A study of informal learning spaces in university student residences based on ergonomics

Student residences are the main place of informal learning for students, extending the function of structured formal learning spaces. Instead of presenting a monotonous and mechanical atmosphere, these informal learning spaces should create a comfortable and relaxing environment. The design of informal learning spaces in student flats is directly related to students' learning efficiency and physical and mental health. Most of the existing studies have examined and researched the informal learning space or ergonomics from a single point of view, but few scholars have considered the design of informal learning space in college student apartments from the perspective of ergonomics. Therefore, this paper firstly defines the connotation of informal learning space in college student flats, then analyses the human-machine-environment system of informal learning space in college student apartments based on human-computer science, and finally puts forward suggestions for the design of informal learning space in college student apartments.

A study on factors influencing the spatial oppressiveness in small courtyard spaces within university residential areas

ABSTRACT A number of obstacles in terms of the growing demand for residential spaces for students in China's education industry. Changing urban development patterns often lead to densely populated, unpleasant university residential neighborhood, posing threats to the well-being of university personnel. This study addresses the limitations of past research, focusing on a real campus's enclosed high-rise student apartment courtyard. Using three key design variables (courtyard area, building height and ground-level interface transparency), 27 sample scenarios were developed for psychological experiments. The findings indicate that while visual scene complexity has minimal impact on oppression to confined environments, building exposure and sky visibility do. People's perception of openness is determined by building exposure, sky visibility, and visual complexity. Higher visual complexity and greater sky visibility enhance the sense of openness. Satisfaction is primarily influenced by sky visibility. The study also conducts a multiple linear regression of spatial and psychological indicators and discusses the tolerance threshold for spatial oppressiveness and the spatial oppressiveness under various spatial types of samples.

Fire-Spread Characteristics and Evacuation Plan Optimization of Old Style Multi-Story Student Apartments

Fire is a major disaster event that can have a significant effect on public safety and social development. In a college or university, fire can seriously threaten the safety, lives, and property of those there due to the compact layout of apartment buildings and high population density. The ecological safety and sustainable development of buildings are also affected. In this study, PyroSim and Pathfinder software (version 2019) were used to simulate and analyze fire-spreading characteristics based on a multi-story university student apartment building. Additionally, the most effective safe evacuation plan from four fire evacuation drill schemes was identified by analyzing and comparing their performance. Results show that the spreading of fire smoke on different floors is significantly affected by the roof structure and the vertical and horizontal diffusion characteristics of smoke. While the smoke layer at the evacuation stairways has little effect on a safe evacuation, poor visibility due to smoke and ceiling temperatures has a significant effect. Safe evacuation becomes progressively more difficult at different floor levels from the top to the bottom of the building. The optimal safety scheme involves orderly evacuation through two open emergency exits. The number of emergency exits has a significant impact on the evacuation effectiveness. Measures and suggestions have been proposed to deal with apartment fires that address pre-event prevention, emergency loss reduction during the event, and post-event report-back. These proposals form an important theoretical reference for emergency evacuation and student apartment fire safety, providing important guidance for ecological safety protection of buildings and sustainable development.

Perancangan Apartemen Mahasiswa dengan Pendekatan Biophilic Design di Dramaga Bogor

The existence of the Bogor Agricultural Institute (IPB), has become one of the factors of the fast development in Dramaga District of Bogor. Dramaga's development can be seen from the growth of vertical commercial and residential buildings. The growth of vertical housing is based on the purpose of marketing to IPB students. Along of recent years, IPB students have increased which makes the rental housing market compete to provide residential facilities as Student Apartments. The growth number of IPB students was not followed by the growth of rental housing. Based on the research results, there are students who carefully decide where they want to live along their study. The Biophilic Design approach, being able to participate helps connect activity users (residents, managers, and visitors) to be active in social interaction. Not only the relationship between humans but also as an access to the relationship between humans and nature. Biophilic Design can also reduce student stress caused by activities while studying. The method in this research is direct observation, literature review and design analysis with the results of concrete concepts. This research provides a solution for meeting the needs of housing with a typology of forms and spatial patterns that provide a sense of connection with nature.

Prodvizhenie ideologicheskogo i politicheskogo vospitaniya v studencheskih obshchezhitiyah v ramkah modeli «Bol'shaya mysl' i politika»

This article expounds the significance of strengthening ideological and political education (IPE) in university student apartments under the background of “big thought and politics”, and discusses how to give full play to the IPE function of apartment management in the stage of student apartment management.

Visualization of Emergency Evacuation Physical Behavior under Multi-Agent Decision-Making

Emergency evacuation simulation is significant for architectural design and emergency plan implementation. To explore the influence of evacuees’ physical behavior and evacuees’ decisions on the evacuation process, as well as to address the problems of traditional emergency evacuation models with insufficient detail of the situation (realism), low reusability, poor operability, and lack of subsequent scalability, this paper first analyzed pedestrian characteristics in emergencies. To describe pedestrian decision-making in an emergent evacuation situation, a multi-agent design based on decision theory was proposed, solving the multi-agent decision-making problem in an emergency evacuation environment by the A* algorithm. Then the designed multi-agent was embedded into the social force model by AnyLogic software. Finally, the model reproduces the pedestrian evacuation process in an emergency evacuation situation on the built platform, depicting three kinds of typical behaviors: pedestrian partnering, obstacle avoidance, and exit competition. In addition, this study also analyzed a large student apartment building by example and proposed corresponding optimization solutions to improve its evacuation capacity through simulation results.

Impact of thermal comfort on online learning performance

Online learning has drawn much more attention since the outbreak of COVID-19. Most related studies have focused on online platform design and instructional design. However, the physical environment where online learning is conducted (e.g., students' homes) is rarely studied. To understand the thermal conditions in students' online learning environment and its impact on students' thermal comfort and their performance during online learning, an experiment, including both objective measurement and subjective assessment, was conducted in a student's apartment. Thirty university students participated in this experiment, and they were randomly assigned into six groups (three thermal conditions (i.e., control, cold, and hot) × two-course durations). Both environmental parameters (i.e., air temperature, radiant temperature, air velocity, etc.) and physiological parameters (i.e. skin temperatures) were measured at the same time. Besides, students' thermal sensation, acceptance, and learning performance were self-evaluated and collected through questionnaires. Results showed that participants' thermal sensation was positively correlated with their mean skin temperature (MST) and the operative temperature (To) in the apartment (MST: ρ = 0.94, p < 0.001; To: ρ = 0.91, p < 0.001), yet no significant relation with their personal characteristics was observed in the current study, which might be caused by the small sample size. Moreover, inverted U-shape relationships were identified between participants' perceived performance and their thermal sensation/MST/To. When students felt slightly cool (TSV = −0.3), they thought they could reach their best performance. This study revealed the impacts of the thermal environment on students' online learning performance, more performance tasks could be conducted in the future to examine the impacts in more detail.

Reducing electricity peak loads through ‘pause hours’ - a community-based behavioural demand response approach

Households can provide demand-side flexibility by changing their consumption behaviour and shifting energy-intensive activities – such as vacuuming, cooking or charging electric cars – to off-peak hours. Such behaviour-based demand response management could balance out consumption peaks without the need for costly smart home devices or automation technologies. However, existing research has struggled to motivate consumers to adapt their behaviour or maintain behaviour change over extended periods of time. This field study explored a scalable and cost-effective behavioural demand response tool and investigated its short- and long-term impacts on average and peak hour electricity consumption under realistic conditions: A smartphone app provided users with social comparison feedback on their electricity consumption and invited them to participate in “pause hours” by avoiding energy-intensive activities during peak hours. To appeal even to hard-to-reach energy users and elicit longer-term engagement, the app also contained a neighbourhood newsfeed and was framed as a local social network. In a 15-month trial with 550 student apartments in Sweden, more than half of the residents voluntarily installed the app, many app users stayed engaged over an extended period of time and pause hour participants achieved substantial peak-load consumption reductions of 46% on average. These results indicate that smartphone apps can achieve peak load consumption reduction and long-term engagement, although they may be particularly attractive to already energy efficient households. Avenues for future research are discussed.

Study on the Energy Efficiency Improvement and Operation Optimization of a Solar Water Heating System

The solar-assisted electric boiler water heating systems adopted in student apartments at universities have some shortcomings, such as unsuitable system designs, unstable water supply temperature, and excessive power consumption. As discussed in this paper, the hot water supply system was reformed, and two apartments with the same building area, same solar collector area, and similar water consumption were selected to be used in comparative experiments. The auxiliary heat source for one of the apartments was changed from an electric boiler to three air source heat pumps, and a constant temperature water tank was added to form a double-tank water supply system. In addition, the operation strategy was adjusted. The other apartment was not modified. The energy consumption, solar fraction, water supply quality and economy of the two systems were analyzed and compared. The results showed that the transformation plan is reasonable and feasible. The solar fraction of the reformed system was significantly improved. The water supply temperature of the original system ranged from 35 °C to 60 °C, but it was shown to stabilize between 40 °C and 50 °C after the transformation. The average power saving rate of the reformed system reached 72.70%, and this economic benefit is highly significant. Additionally, the TRNSYS simulation software was used to model and optimize the control of the system.

An Evaluation of the PV Integrated Dynamic Overhangs Based on Parametric Performance Design Method: A Case Study of a Student Apartment in China

A photovoltaic shading device (PVSD) is a promising technology that can both generate electricity and provide shading to reduce indoor energy consumption. This paper aims to evaluate the performance of three PVSD design strategies in five Chinese cities by using a proposed all-in-one simulation program, according to the parametric performance design method. The program can be used to predict the energy consumption, power generation, and economic feasibility of different PVSD strategies. It was, firstly, calibrated through an actual experiment which was carried out in Qingdao and, secondly, used to simulate the energy consumption and generation of the three PVSD strategies in relation to the optimal angles and heights. Finally, the program was used to calculate the energy efficiency and economic feasibility of the three strategies. The findings indicated that the move-shade strategy of PVSD can provide the best energy-saving performance, followed by rotate-shade and fixed-shade strategies. Compared to the no-shade strategy, the reduction of the net energy use intensity by using the move-shade strategy was 31.80% in Shenzhen, 107.36% in Kunming, 48.37% in Wuhan, 61.79% in Qingdao, and 43.83% in Changchun. The payback periods of the three strategies ranged from 5 to 16 years when using the PVSD in China.

Empowering Consumers within Energy Communities to Acquire PV Assets through Self-Consumption

The use of photovoltaic energy (PV) and the involvement of residents within energy communities are becoming increasingly important elements of decentralized energy systems. However, ownership structures are still too complex to empower electricity consumers to become prosumers. We developed a token-based system of the gradual transfer of PV ownership rights, from the initial investor to residential and small-scale commercial consumers. To demonstrate the system, we set up a simulation of a 27-party mixed usage building with different load profiles, ranging from single student apartments to office units with battery electric vehicles, in a German energy community. As a result, we show that the proposed system design is economically viable for all involved stakeholders over the simulation horizon from 2022 to 2036, with a payback time of &lt;5 years, 4 years to distribute 50% of the PV tokens, and an overall self-consumption share of 69%.

Research on Health and Thermal Comfort of Unit-Type Student Apartments in the Western China Science and Technology Innovation Harbor.

BackgroundIn China, the collective living mode of “multiple people living in one room” is widely used in college students' dormitories; the space environment has high personnel density and poor thermal comfort and healthy environment. The unit-type apartments were completed in the western China science and technology innovation harbor that considers personal independence and public activity spaces.AimThe purpose of this study is to explore the applicability, thermal comfort, healthy environment, and the correlation of influencing variables of the new unit-type apartment. Especially the influence of physical parameters on personal space under heating in winter and air conditioning in summer.MethodThe field investigations and questionnaires to conduct a personal study of architectural space, healthy environment, and thermal comfort were carried out, and the measurement tests of the building's physical environment were carried out in winter and summer semesters.ResultsThe questionnaires survey shows that the privacy of the unit apartment is satisfactory, and the independent learning and communication is increased. The field measurement results show that due to the narrow space of the private room, the floor radiant heating mode still forms a hot and dry thermal environment in winter, and the temperature fluctuates significantly after the air conditioner is turned on in summer.ConclusionsThe unit-type apartments align with young students' physiological and psychological characteristics and the behavioral aspects of postgraduates, with high comprehensive satisfaction up to 80%. However, the indoor thermal environment quickly fluctuates due to the narrow independent space. Moreover, 90% of the window ventilation ratio shows that it has become the main measure to actively regulate the indoor climate, which is beneficial to students' health but increases energy waste and further aggravates the fluctuation of the thermal environment. More refined regulations should be executed for heating in winter and air conditioning in summer.

Student Apartments: from the History of Everyday Students Life of Yelisavetgrad Six-Class Pprogymnasium in the 80s of the 19th Century

The aim of this article is to explore the main aspects of Yelisavetgrad six-class progymnasium management, related to the opening of student apartments, living arrangements and supervision of the students living in those apartments; to analyse the rules that regulated the living conditions of progymnasium students in the mentioned apartments and apartments of relatives. The research methodology is based on a combination of general scientific (analysis, synthesis, generalization) and special-historical (historical-typological, historical-systemic, historical-genetic) methods. The study is based on the principles of historicism, systematicity and scientificity. Based on archival documents, the mechanisms, features and practice of student apartments opening for the students of Yelisavetgrad men’s progymnasium are studied for the first time, which presents the scientific novelty. The forms of control over the personal space of the students by the teaching staff of the progymnasium and the students’ reaction to the established rules are clarified. Analysis of the sources showed that during the 1980s the issue of resettlement of non-resident students was extremely important for Yelisavetgrad educational institutions. In the absence of boarding houses, the increase in the number of students prompted the management of educational institutions to develop rules governing the opening of student apartments, regulating the living conditions of the students and forms of control by the institution over compliance with the rules of both tenants and students. The analysis of the protocols of Yelisavetgrad men’s six-class progymnasium pedagogical council shows that the educational institution treated the opening of student apartments and supervising the living conditions of the students very responsibly: sanitary and hygienic conditions, as well as opportunities to conduct educational activities qualitatively, were taken into account. The control over the observance of the rules was systemic. Probably, this decisively contributed to the fact that among the progymnasium students there was a galaxy of outstanding figures of culture and science. On the other hand, the recollections of former progymnasium students contain facts of intrusion into personal space, which made students feel discomfort associated with strict regulation of living conditions. The study of the pedagogical council meeting protocols makes it possible to trace the fate of the students who due to the difficult financial situation of their families could not pay for accommodation in student apartments allowed by the progymnasium management, so they lost the right to complete education and get the chance for a better life.

Research on The Hidden Dangers and Countermeasures of Electricity Safety in College Students’ Apartments

Students’ apartments in Colleges and universities are densely populated, which is a high incidence area of campus fire. There are many hidden dangers of electrical safety in student apartments. In terms of buildings, the infrastructure construction is not standardized, the overall function design does not match, the power supply and distribution lines and safety facilities cannot meet the current needs of life, the power lines are aging, the insulation layer is damaged, and so on. In terms of power consumption, high-power electrical appliances are used in violation of regulations and requirements. The reasons for the above safety risks are: the school management personnel have weak safety awareness, do not pay enough attention to the safety management of electricity, the quality of some electrical equipment is not up to standard, the hidden danger investigation and rectification is not strict, and so on. The main countermeasures are: the school should fulfill the main responsibility of safety work, strengthen the apartment safety management, strengthen the students’ awareness of electrical safety, popularize the knowledge of electrical safety, investigate and rectify the hidden dangers of electrical safety, etc.
