Research on Hybrid Heating System in Cold Oilfield Regions

Efficient and clean treatment of wastewater and energy recovery and utilization are important links to realize low-carbon development of oilfields. Therefore, this paper innovatively proposes a multi-energy complementary co-production heating system which fully and efficiently utilizes solar energy resources, oilfield waste heat resources, and biomass resources. At the same time, a typical dormitory building in the oil region was selected as the research object, the system equipment selection was calculated according to the relevant design specifications. On this basis, the simulation system model is established, and the evaluation index and operation control strategy suitable for the system are proposed. The energy utilization rate of the system and the economic, energy-saving, and environmental benefits of the system are simulated. The results show that, under the simulated conditions of two typical days and a heating season, the main heat load of the system is borne by the sewage source heat pump, the energy efficiency is relatively low in the cold period, and the energy-saving characteristics are not obvious. With the increase in heating temperature and anaerobic reactor volume, the energy consumption of the system also increases, and the energy efficiency ratio of each subsystem and the comprehensive energy efficiency ratio of the system gradually decrease. In addition, although the initial investment in cogeneration heating systems is high, the operating costs and environmental benefits are huge. Under the condition of maintaining 35 °C, the anaerobic reactor in the system can reduce carbon emissions by 12.15 t per year, reduce sulfur dioxide emissions by 98.4 kg, reduce dust emissions by 49.2 kg, and treat up to 2700 t of sewage per year, which has broad application prospects.

The planned building consists of 7 floors, including the lower structure consisting of a 50x50 square pile foundation and five types of pile cap, the upper structure consisting of columns, beams, and floor plates. The quality of concrete in the structure used is fc' 40 Mpa and 35 Mpa with reinforcing steel quality fy 420B. In this planning, 2D and 3D modeling was carried out. Structural analysis was carried out using the SAP2000 application, which was then continued with 2D 3D modeling and Quantity take-off results using Revit and Scheduling using Ms. Projects. The Draft Budget (RAB) results for this planning are Rp. 37,691,368,000.00. The planned duration of work is 26 weeks. The results of the scheduling and RAB are then integrated using the Naviswork software so that the simulation results of the work to be planned can be seen.

Technical issues on forensic assessment of post-earthquake building damage—Case study of the Hajj Dormitory Building, Mamuju, Indonesia

In the wake of frequent, strong earthquakes in Indonesia, detailed and comprehensive forensic assessments of post-earthquake building damage are necessary. On January 14, 2021, a destructive Mw 6.2 earthquake occurred in Mamuju–Majene, West Sulawesi, Indonesia. Over a hundred houses and facilities were heavily damaged, and there were even fatalities and injured people. Therefore, forensic work is required to assess the conditions and performances of existing buildings to ensure their safety. However, determining a building’s seismic capacity and safety after an earthquake is a challenge. It is substantially challenging to accomplish it solely through visual inspections, which must be done rapidly and during an emergency. This paper reports a complete assessment of the Hajj Dormitory building. An extensive forensic method including visual and detailed inspections was planned and performed. Detailed inspections comprised verticality, ultrasonic pulse velocity test, rebound hammer test, crack measurement, rebar scan/cover meter test, core drill, and geoelectric and cone penetration tests. Results showed that the Hajj Dormitory building superstructure was still safe and reliable; however, mandatory retrofitting was required in several parts of the column and beam. Further, technical issues associated with post-earthquake forensic methods of observed damage and their utility on the safety and reliability of an inspected building are presented, and recommendations are made based on extensive in situ work. Moreover, correlations and recommendations for each forensic method are presented, along with detailed rules of damage assessment.

Views of Bumi Siliwangi Dormitory Residents on the Need for the Use of Rainwater Reservoirs

The Bumi Siliwangi Dormitory is a facility provided by the University of Education Indonesia with a total of three buildings, including the women's dormitory building, the men's dormitory building, and the men's and women's runaway building. This study aims to examine the perception of dormitory residents towards the urgency of using rainwater reservoirs in the Bumi Siliwangi Dormitory, Universitas Pendidikan Indonesia (UPI), as well as to find out the number of clean water needs of dormitory residents, as an effort to overcome the problem of lack of clean water due to water pumps that are often damaged. This research method uses a descriptive method with a quantitative and qualitative approach. Primary and secondary data were collected from the Bumi Siliwangi Dormitory Building, with the research subjects in the form of dormitory residents and dormitory managers. The analysis of water needs is carried out based on urban water demand standards. The results of the study show that the dormitory water requirement is 18,352,200 liters/year, while the clean water capacity produced reaches 78,840,000 liters/year. Based on these results, it can be concluded that rainwater harvesting is not needed at this time.

Performance Analysis and Optimization of Solar-Coupled Mine Water-Source Heat Pump Combined Heating and Cooling System

To address the energy consumption issue in mining area buildings, this paper proposed a solar-coupled mine water-source heat pump combined heating and cooling (SMWHP-CHC) system, taking the employee dormitory building group of a coal mining enterprise in Tongchuan City, China, as a case study. The system utilizes renewable solar energy and waste heat recovered from mine water as composite heat sources, and utilizes the cold energy in mine water as a cooling source to meet the demands for space heating, space cooling, and annual domestic hot water of the building in a sustainable manner. The simulation model of the system was established by TRNSYS to analyze the system’s annual operational performance. The results indicated that the system exhibited a positive energy efficiency and environmental performance under different operating conditions. The heating coefficients of the performance of the system (COPsys) during the space heating season and transition season were 3.54 and 18.6, and the cooling energy efficiency ratio of the system (EERsys) was 3.79. In addition, aiming to minimize the annual cost of the system, multiple crucial device parameters were synchronously optimized employing the PSO-HJ hybrid optimization algorithm through the GenOpt 2 software. The annual cost of the optimized system was reduced by 8.82%, and the investment cost was significantly reduced, while the performance was also improved. This study can provide theoretical support for the sustainable engineering application of the SMWHP-CHC system in mining area buildings.

I reviewed the legal issues arising from the BTL project, focusing on the case of Jeju National University.

THE DESIGN INNOVATION WITH A BIOPHILIC APPROACH TO SUPPORT THE TEMPORARY CONVERSION OF STUDENT DORMITORY AS A COVID-19 ISOLATION SHELTER

The increasing number of Corona Virus Disease (COVID-19) cases in Bandung, Indonesia, in July 2021 resulted in a higher hospital bed occupancy rate. The conversion of two student dormitory buildings into isolation shelters is expected to accommodate COVID-19 patients who do not have rooms in the hospital. This requires specific planning and innovation, particularly for materials. This study has two objectives: first, to evaluate how long coronaviruses can remain active on different material surfaces. The data collection strategy was carried out through Systematic Review. The second research objective was to design a COVID-19 isolation room that uses materials that facilitate the healing process. Field surveys and traditional literature reviews were conducted for this purpose. This study found that the virus did not survive long on the surfaces of cotton and cardboard. Thus, the room design uses these materials and is considered a biophilic design. This study is expected to provide insights for academics and researchers in interior design and architecture regarding the knowledge of furniture materials that prevent viruses from surviving longer. In addition, it is expected to inspire interior designers to design rooms that can help the healing process using a biophilic approach.

Research on the Design of Recessed Balconies in University Dormitories in Cold Regions Based on Multi-Objective Optimization

Thermal comfort and daylighting are vital components of dormitory environments. However, enhancing indoor lighting conditions may lead to increased annual energy consumption and decreased thermal comfort. Therefore, it is crucial to identify methods to reduce buildings’ energy costs while maintaining occupants’ thermal comfort and daylighting. Taking the dormitory building of Songyuan No. 2 at Shandong Jianzhu University of Architecture, which is located in a cold region, as an example, a field measurement analysis was conducted on the recessed balconies within the dormitory. The measured data were analyzed and utilized to simulate the annual energy consumption, thermal comfort predicted mean vote (PMV), and useful daylight illuminance (UDI) values of the dormitory units using the Grasshopper platform with the Ladybug and Honeybee plugins. The different depths of the balconies and window-to-wall ratios have a significant impact on the indoor physical environment and energy consumption, leading to the design of independent variables and the construction of a simplified parametric model. The simulation results underwent multi-objective optimization using genetic algorithm theory through the Octopus platform, resulting in a Pareto optimal solution set. Comparisons between the final-generation data and simulations of the original Song II dormitory unit indicate potential energy savings of up to 2.5%, with a 25% improvement in indoor thermal comfort satisfaction. Although there was no significant improvement in the UDI value, all the solution sets meet the minimum requirement of 300 lux specified by relevant regulations, according to the simulated average illuminance levels on the indoor work plane. Finally, the 60 optimal solution sets were further screened, filtering out sets deviating excessively from certain objectives, to identify 6 optimal solutions that are more balanced and exhibit a higher overall optimization rate. These findings offer detailed data references to assist in the design of dormitory buildings in cold regions.

Short-term energy consumption prediction for university dormitory buildings based on energy consumption grouping by considering meteorological factors and teaching schedules

Accurate short-term energy consumption prediction is essential for studying renewable energy utilization in building technologies. University dormitory energy consumption is affected by meteorological factors and teaching schedules, presenting a more complex time series compared to residential buildings, rendering traditional methods unsuitable. Therefore, in the present study, we developed a model called energy consumption grouping-Improved Complete Ensemble Empirical Mode Decomposition with Adaptive Noise-Bi-directional Long Short-Term Memory (ECG-ICEEMDAN-BILSTM) for predicting short-term energy consumption in university dormitory buildings. Model was tested using electricity consumption data from university dormitory buildings in cold regions of China. Based on the energy consumption characteristics, we identified two consumption patterns comprising high power energy consumption (HPEC) and low power energy consumption (LPEC). Using the ECG method, data with similar daily energy consumption distributions for HPEC and LPEC were grouped. Subsequently, individual prediction models were constructed based on ICEEMDAN-BILSTM for each specific energy consumption group. The experimental results showed the ECG-ICEEMDAN-BILSTM model obtained more accurate predictions compared with other neural network models. In addition, the model was more effective at forecasting the complex distribution of the HPEC pattern, with reductions of at least 16.21% and 15.82% in MAPE and PRMSE, respectively. Thus, study still can obtain valuable insights to address the problem of short-term prediction using complex time series.

A study on natural ventilation of dormitories for college students in northeast China during spring: A case of linear-shaped dormitory buildings

This study employed computational fluid dynamics to investigate the natural ventilation efficiency and indoor air temperature changes in different rooms of a linear-shaped dormitory building at a university in northeastern China during the spring season. Using a four-student dormitory in Jilin City as a physical model. Volume ratio of air age curves, depicting indoor air quality, are constructed based on air age values. Due to the dormitory building's symmetry, five wind angles, averaged from 0° to 90° (N - E), are chosen as typical. The results indicate that, following adequate ventilation, the average indoor air temperature (Temstabilize) can be stabilized above 11 °C in rooms located on the leeward side of the dormitory building. Specifically, rooms located on the upwind area at wind angles of 22.5° and 45°, as well as rooms near the environmental air inlets and outlets at wind angles of 67.5° and 90°, can maintain an average air temperature above 15 °C. However, the minimum continuous ventilation time (Tmin) required for these rooms exceeds 1200 s. On the windward side of the dormitory building, rooms near the environmental air inlets and outlets exhibit high ventilation efficiency, but the air temperature in these rooms decreases more rapidly. When the wind angle is 45°, 67.5°, or 90°, the average indoor temperature in these rooms falls below 11 °C. Through normalization analysis, a significant linear relationship is observed between Tmin and Temstabilize data, represented by the numerical relationship Tminnorm=1.0134×Temstabilizenorm. The findings of this study are valuable for assisting students in developing ventilation plans and can also serve as a reference for architects designing dormitory buildings based on prevailing wind directions in the area.

Earthquake-Induced Waste Repurposing: A Sustainable Solution for Post-Earthquake Debris Management in Urban Construction

Product sustainability has moved beyond being an elective preference to becoming a certain necessity. However, earthquakes in different regions, particularly Türkiye–Syria, Afghanistan, and Morocco, have produced a substantial amount of construction waste and debris. In the context of green urban initiatives and environmental preservation, theeffective management and reduction of environmental impact (EI) are imperative. This urgency underscores the significance of the study’s focus on a ten-story reinforced concrete (RC) dormitory building in Győr, Hungary, chosen as a case study. The research delves into the incorporation of three distinct concrete compositions through seismic design, aligning with the innovative approach of emphasizing recycled aggregate-based concrete to mitigate the EI. Utilizing AxisVM X7 and Revit software, the study meticulously created and analyzed a detailed building model, revealing a significant percentage (35%) and amount (1519.89 tons) of concrete waste that could be incorporated into construction. The results also showed a reduction in both total carbon emissions and the price of materials by falling 27.5% and 9.13%, respectively. We propose an eco-friendly way to effectively reuse debris from earthquakes, focusing on the case study of the 2023 Türkiye–Syria earthquake and encouraging resource efficiency while also addressing the construction waste problems that arise after an earthquake.

Achieving Energy Self-Sufficiency in a Dormitory Building: An Experimental Analysis of a PV–AWHP-ERV Integrated System

In this study, we investigated the performance of air-to-water heat pump (AWHP) and energy recovery ventilator (ERV) systems combined with photovoltaics (PV) to achieve the energy independence of a dormitory building and conducted an analysis of the energy independence rate and economic feasibility by using energy storage devices. Our data were collected for 5 months from July to November, and the building energy load, energy consumption, and system performance were derived by measuring the PV power generation, purchase, sales volume, AWHP inlet and outlet water temperature, and ERV outdoor, supply, and exhaust temperature. When analyzing representative days, the PV–AWHP integrated system achieved an energy efficiency ratio (EER) of 4.49 and a coefficient of performance (COP) of 2.27. Even when the generated electrical energy exceeds 100% of the electricity consumption, the energy self-sufficiency rate remains at 24% due to the imbalance between energy consumption and production. The monthly average energy self-sufficiency rate changed significantly during the measurement period, from 20.27% in November to 57.95% in September, highlighting the importance of energy storage for self-reliance. When using a 4 kWp solar power system and 4 kWh and 8 kWh batteries, the annual energy self-sufficiency rate would increase to 67.43% and 86.98%, respectively, and our economic analysis showed it would take 16.5 years and more than 20 years, respectively, to become profitable compared to the operation of an AWHP system alone.

Where does perceived control come from? A survey of a dormitory building across different operation modes in summer

Prior studies have attributed the heightened positive thermal response during summer to perceived control. The process through which perceived control is cultivated in the built environment has been scarcely explored. A field study was conducted in a dormitory building operating successively in natural ventilation and mixed-mode in the cold region of China. A total of 922 valid samples were obtained. The data analysis indicated that the building’s operation mode impacted both perceived control and its influencing factors. In natural ventilation mode, occupants perceived less control than in mixed-mode, and perceived control was shaped by both thermal stimulus and exercised control. Conversely, in mixed-mode, the occupants’ perceived control was solely influenced by exercised control. Reflecting on this result, this study is the first to suggest a method for determining ‘perceived effectiveness’ by assessing occupants’ thermal sensations and preferences. Only air conditioning was perceived as effective, amplifying occupants’ perceived control, while other controls diminished it. In mixed-mode, control combinations incorporating air conditioning were judged to have perceived effectiveness. On this basis, further combining psychological adaptation with behavioural adaptation, active and passive technology was used to play the role of behavioural adaptation, and the upper limit of acceptable temperature for occupants was increased to 31.1°C.

Air Quality of Private Interiors during the COVID-19 Pandemic: A Case Study of Dormitory Interiors as Shared Spaces

COVID-19 was a wake-up call for many researchers and designers that encouraged them to create better interiors. Keeping air quality within safe standards is fundamental and the best strategy to stop the spreading of viruses. Being aware of the severity of indoor transmissions of infections, exploring and understanding how they are spread, and how to avoid them can be critical steps to enhance public health. However, many of the private spaces, residential areas and places where multiple people accommodate together remain unattended, such as dormitory buildings. Since many of them do not have an HVAC system, natural ventilation is the primary method for airing dormitory rooms. Therefore, this study aims to reveal existing ventilation conditions in university dormitories, occupants’ behaviors, disinfection, and air cleaning methods in wintertime. For this, a dormitory complex was selected in Ankara (Turkey), whose climate can be compared to many other cities in the northern hemisphere, as an initial case study to provide insight. Overall, it was found that window-opening behaviors of university students are mostly determined by the density of their rooms. The study findings will raise awareness and motivate further studies in architecture, interior architecture, and design disciplines and provide initial knowledge about the topic.

Indoor environment in Sri Lankan university dormitories: Associations with ocular, nasal, throat and dermal symptoms, headache, and fatigue among students

This study investigated the prevalence of medical symptoms, including headache, fatigue, ocular, nasal, throat, and dermal symptoms, among university students and their associations with the indoor environment of Sri Lankan dormitories. The study included 2234 students from seven different dormitory buildings. The association between dormitory environmental factors and students' medical symptoms was determined using multi-level logistic regression. General symptoms (22.8%) were reported more frequently than other symptoms. Headaches (11.6%) and fatigue (11.3%) were the most common specific individual symptoms. The most frequent dampness-related problems were visible mold (29.6%) and visible damp stains (28.8%). Significant gender differences were observed. Suspected moisture problems were a major risk factor for ocular (AOR: 2.65), fatigue (AOR: 1.83), and throat symptoms (AOR: 2.49). Damp stains were also associated with an increased risk of fatigue (AOR: 1.52), ocular (AOR: 1.72), throat (AOR: 2.26), and dermal symptoms (AOR: 1.61). The mutual adjustment model revealed that any type of dampness, as well as being on a lower floor level of the building, was a significant risk factor for the occurrence of throat, dermal, general, and mucosal symptoms. Residing in older buildings was a protective factor for ocular and nasal symptoms. Infrequent window opening was associated with increased medical symptoms. The findings suggested that the dormitory environment has an effect on students’ health. Opening windows on a regular basis may improve airflow in dormitories. Future dormitory designs should consider large windows in areas with lower levels of outdoor air pollution, and mechanical ventilation systems should be considered.

The Reliability Level of Women's Dormitory Building Ibn Khaldun University Bogor

The Ibn Khaldun University Women's Dormitory Building, Bogor (ASPIKA) is a building that functions as a temporary residence for female students. The ASPIKA Building was established 13 years ago, this has resulted in several building components and structures experiencing some damage which resulted in the function of the ASPIKA Building decreasing, so an assessment of the reliability level of the building is needed. Aspects used in the assessment of the reliability of the ASPIKA Building based on the proper function of the building include aspects of architecture, structure, utility and fire protection, accessibility, and building layout taking into account the applicable SNI standards. The method used is descriptive quantitative as well as survey data of the existing building by the Minister of Public Works No. 2/PRT/M/2006 concerning Guidelines for Building Technical Requirements. The results showed that the percentage value of the building on the architectural component aspect was 95.50%, indicating the building is in reliable condition. The percentage value on the structural component aspect of the building is 96.56%, indicating that the building is still reliable. The percentage of utility and fire protection components has a value of 65% indicating that the component aspects of the building are not reliable. Unreliable factors in utility and fire protection components are influenced by an inadequate fire prevention system so more attention must be paid to these aspects. Components in the accessibility aspect get a percentage of 65%, meaning that they are less reliable, where this value is influenced by the limited access of people with disabilities to reach areas on each floor of the building. The building layout and the environment get a 100% percentage which identifies the building layout as reliable based on the documents on the ASPIKA Building. The total value of the reliability level of ASPIKA Buildings obtained is 79.41% categorized as "Less Reliable" (reliable category is > 95%), this is influenced by the fire protection component by 65% ​​and the accessibility component by 65%. The solution that can be done by the university is to repair and procure facilities on the fire protection system and provide accessibility facilities that can make it easier for people with disabilities.

Efektivitas Metode Pekerjaan Pelat Lantai Bondek, Half Precast dan Konvensional Gedung Asrama Putra Al-Azhar

The floor plate is one of the important components in a multi-story building. Conventional methods are still widely used for building floor slabs. This method requires a lot of labor and time, which can reduce productivity. Other methods, such as bondek and half precast in floor slab work, are expected to increase work effectiveness and efficiency. This study aims to determine which method is most effective in floor slab work by reviewing cost, time, and work productivity. Floor plate planning consists of calculating each method's structural strength and volume of work, including formwork, reinforcement, concrete, and formwork dismantling. Cost analysis is carried out by collecting data on material prices and labor wages for the building's Draft Budget (RAB). Estimated work time involves formwork preparation, installation of reinforcement, and concrete casting for the three work methods. Based on the results of the calculation analysis on the floor slab work of the Al-Azhar Boys Dormitory Building with an area of the floor plate of 375,318 m2. Conventional floor slab work is more economical than bondek slab work by around 31.23%, but requires the longest work time. Meanwhile bondek floor slabs offer the fastest processing time, even though the cost is higher than conventional slabs, around 31.19% and 5.18% lower than half precast slabs. This can be a recommendation in choosing a floor slab work method.
