The study examined various types of flat metal sheet roofs and the effects of solar intensity, using a solar simulator equipped with halogen lamps to replicate solar energy. Experimental results revealed that as solar intensity increased, the attic temperature also rose. The flat metal sheet roof equipped with closed-loop oscillating heat pipe, with forced heat convection via a fan, exhibited the best heat transfer efficiency. The attic temperature was reduced to a minimum of 38.3°C at a maximum solar intensity of 600 W/m². This indicates that the heat pipes effectively draw heat from the metal sheet roof surface and transfer it to the atmosphere before it enters the attic.</p> Nopparat Seehawong Ninnart Rachapradit Piyanun Charoensawan Copyright (c) 2025 Journal of Energy and Environment Technology of Graduate School Siam Technology College https://creativecommons.org/licenses/by-nc-nd/4.0 2025-06-30 2025-06-30 12 1 41 50 The Assessment of Household Energy Consumption and Renewable Energy Potential : A Case Study in Mueang Gaen Municipality, Chiang Mai Province https://ph01.tci-thaijo.org/index.php/JEET/article/view/260997 <p>This objective of this study was to assessment the household’s energy consumption and renewable energy potential, as well as propose guidelines for reducing energy consumption by introducing energy technologies.

The appropriate approach to reduce energy use in the community is to use leftover materials from rice cultivation and animal feed, including using animal waste to produce biogas and use it as heat energy instead of using LPG.</p> Tanawat Chaiyo Rotjapun Nirunsin Pakamon Pintana Tanate Chaichana Copyright (c) 2025 Journal of Energy and Environment Technology of Graduate School Siam Technology College https://creativecommons.org/licenses/by-nc-nd/4.0 2025-06-30 2025-06-30 12 1 51 61 Towards Sustainable Agriculture: Strategies for Energy Efficiency and Environmental Conservation in Banana Cultivation and Processing https://ph01.tci-thaijo.org/index.php/JEET/article/view/261528 <p>Promotion of renewable and alternative energy usage on a local level can effectively lead to increased national renewable energy potential, along with distributing energy security towards communities. This scheme aligns with national development goals on various levels. Thailand aimed to increase the proportion of renewable and alternative energy usage to final energy consumption to 30% by 2037. This research was conducted through collecting data of energy usage in banana cultivation and banana processing. A questionnaire/interview was used for a selected group of banana farmers. The data of banana processing was gathered with another questionnaire/interview for banana drying and frying processes. It was found that energy consumption for banana cultivation amounted average to 54,000 baht per year, or an equivalent of 1.92 toe per year. Energy consumption for banana process was equal average to 421,228.20 baht per year, or an equivalent of 8.40 toe per year. In light of the findings, the renewable energy measure of implementing 3,200-watt solar-powered mobile water pump system for banana cultivation was considered suitable. Which can be used to replace diesel oil for watering 100%. On the other hand, for banana processing, the use of 6.0x8.2 m² parabola dome solar dryer was appropriate. This allowed the group to increase the proportion of renewable energy use equivalent to 86,109.30 kWh per year and reduce energy costs by approximately 361,659.06 baht per year. The aforementioned implementations of renewable energy measures serve as prototypes which can be further perpetuated, fulfilling the policies of the government.</p> Seksan Nanthakhet Thakrit Panklib Jutarat Keawboonchu Copyright (c) 2025 Journal of Energy and Environment Technology of Graduate School Siam Technology College https://creativecommons.org/licenses/by-nc-nd/4.0 2025-06-30 2025-06-30 12 1 62 71 The development of a temperature and humidity control system in a split-type ceiling-suspended air conditioner to optimize energy usage in classrooms at Siam Technology College https://ph01.tci-thaijo.org/index.php/JEET/article/view/262052 <p>A split-type air conditioner, specifically the ceiling-suspended model, is a cooling system that offers convenient installation. The selection of a split-type air conditioner depends on the size of the area, the nature of usage, and the ability to control temperature. Typically, fixed-speed split-type air conditioners are installed in multiple units within an air-conditioned space, such as classroom 7201 in Building 7 of Siam Technology College. This setup often results in inefficient temperature and humidity control, leading to excessive electricity consumption. Therefore, this research aims to develop a temperature and humidity control system to optimize energy consumption for practical use. Experimental results indicate that the optimal temperature and relative humidity for room 7201 are 25 <sup>o</sup>C and humidity below 60%. The average power consumption is 4,250 watts per hour, which aligns with the appropriate energy usage for air conditioning. This optimization helps prevent equipment deterioration and ensures efficient electricity consumption.</p> Songkran Parakul Kumjat Jaitrong Copyright (c) 2025 Journal of Energy and Environment Technology of Graduate School Siam Technology College https://creativecommons.org/licenses/by-nc-nd/4.0 2025-06-30 2025-06-30 12 1 72 80 Design of an Automatically Expandable Solar Battery Charging System for a 6-Seater Electric Golf Cart https://ph01.tci-thaijo.org/index.php/JEET/article/view/262535 <p>This research was conducted to design and evaluate the performance of an automatic expandable solar charging system for a 6-seat electric golf cart, in comparison with a conventional fixed solar charging system. The study aimed to analyze the differences in electrical energy output and battery charging duration. The experiment was carried out from January to May 2025 at Siam Technology College, Bangkok Yai District, Bangkok, Thailand. Data were collected four days per week (Tuesday to Friday) between 08:00 and 16:00. Two photovoltaic (PV) systems were tested: (1) the fixed system, which utilized a single 550-watt Mono Half Cell solar panel, and (2) the automatic expandable system, which employed one 550-watt Mono Half Cell panel along with two 100-watt panels that automatically extended to increase sunlight exposure. Both systems charged a 48V lithium iron phosphate (LiFePO₄) battery.</p> <p>The results indicated that the automatic expandable system generated, on average, 870 watt-hours more energy per day than the fixed system, and reduced the charging time by approximately 1.5 to 2.0 hours. Solar irradiance was found to have a direct effect on system performance, with both systems operating most efficiently on sunny days and less effectively under cloudy conditions. In conclusion, the automatic expandable solar charging system demonstrated significant potential for enhancing energy production efficiency. It is particularly well-suited for practical applications in electric golf carts and other small electric vehicles, especially in areas where installation space for solar panels is limited.</p> Sarayut Rohitsathian Udomsak Chotimongkol Somboon Kokpha Copyright (c) 2025 Journal of Energy and Environment Technology of Graduate School Siam Technology College https://creativecommons.org/licenses/by-nc-nd/4.0 2025-06-30 2025-06-30 12 1 81 90 Application of Generative AI to Reduce Carbon Footprint from Document Processing in Educational Institutions: A Case Study of NotebookLM https://ph01.tci-thaijo.org/index.php/JEET/article/view/262787 <p>Climate change and greenhouse gas emissions have become critical global concerns, prompting educational institutions to recognize the importance of reducing their carbon footprint through more efficient resource management.

The first step of the research was done to find the appropriate concentration of bleach that can prevent microbial contamination in agar media. The bleach concentration of 0, 0.3, 0.5, and 1.0 ml/l were used. Then, the agar media with the appropriate concentration of bleach was used for the studying on the proper duration of resting before using for plant tissue culture. The resting periods were 0 (no resting), 5, 10, 15, 20, 25 and 30 days compared with the autoclaving agar media as for the growth of begonia. The results of the first step showed that after 4 weeks, the microbial contamination in agar media with bleach concentration at 0 and 0.3 ml/l can be found but at 0.5 and 1.0 ml/l can not be found. Therefore, the bleach concentration at 0.5 ml/l is an appropriate concentration that was used for the studying on the proper duration of resting period. The results found that the agar media with bleach at resting period 10 days gave the best growth of begonia. The average leaf number and shoot height were 15.00 ± 2.16 and 3.25 ± 0.28 cm. respectively. Whereas, the average leaf number and shoot height from the autoclaved agar media were 6.75 ± 1.50 and 2.25 ± 0.28 cm. respectively. The growth of begonia were highly significantly different. So, the used of bleach at concentration of 0.5 ml/l and keep resting agar media for 10 days can be used instead of the autoclaving agar media. As for the estimation of energy saving on non-autoclaving, the preperation of 200 liter of agar media can save the electric power about 250-300 KW that can be calculate as the expense about 1,125-1,350 baht. While the expense on the use of bleach is about 3.40-5.80 baht.</p> Suthep Thongpae Petcharat chuntaratin Copyright (c) 2025 Journal of Energy and Environment Technology of Graduate School Siam Technology College https://creativecommons.org/licenses/by-nc-nd/4.0 2025-06-30 2025-06-30 12 1 116 123 Carbon Footprint (CFO) Forecasting Using Artificial Neural Networks (ANN) in Transportation of Small Trailer Companies in Thailand Based on Vehicle Efficiency Metrics https://ph01.tci-thaijo.org/index.php/JEET/article/view/260141 <p>This article aims to study the trends in carbon footprint (CFO) emissions using artificial neural networks (ANN) in the transportation sector of small trailer companies in Thailand, based on vehicle efficiency metrics such as Overall Vehicle Efficiency (OVE), Transportation Overall Vehicle Efficiency (TOVE), and Modified Overall Vehicle Efficiency (MOVE). These metrics reflect the operational efficiency of trucks in various aspects, including engine combustion, route management, and energy consumption in transportation. ANN can be utilized to analyze CO<sub>2</sub> emission trends by considering factors such as speed, acceleration, payload weight, and road conditions. It can also capture complex relationships within these data and accurately calculate CO<sub>2</sub> emissions. This suggests that ANN can serve as a valuable tool for studying carbon footprint emission trends in the transportation industry. Moreover, the use of ANN enhances forecasting accuracy and improves responsiveness to complex factors. However, challenges remain in managing intricate datasets and addressing the costs associated with system implementation and maintenance.</p> Thanitsak Pudtipatkosit เปรมพร เขมาวุฆฒ์ อานันท์ บุตรรัตน์ กวินเวทย์ พิพิธนาธันยธร อัสรียาภร สง่าอารีย์กุล Copyright (c) 2025 Journal of Energy and Environment Technology of Graduate School Siam Technology College https://creativecommons.org/licenses/by-nc-nd/4.0 2025-06-30 2025-06-30 12 1 124 133 Strategic Analysis for Carbon Footprint Management in Thailand’s Transportation Industry Toward Sustainability https://ph01.tci-thaijo.org/index.php/JEET/article/view/261594 <p>This academic article aims to analyze the current situation and trends of carbon footprint emissions in Thailand's transportation industry and propose strategic carbon footprint management approaches aligned with the Sustainable Development Goals (SDGs) and the Environmental, Social, and Governance (ESG) framework. In 2022, Thailand’s transportation sector emitted approximately 79.6 million tons of carbon dioxide (CO₂), accounting for 32% of the country’s total greenhouse gas emissions, making it one of the most significant contributors. Without urgent mitigation efforts, CO₂ emissions are projected to continue rising, potentially reaching 200 million tons by 2050. Such an increase would pose severe threats to the environment and public health, including intensified climate change, deteriorating air quality, increased incidence of respiratory and cardiovascular diseases, and ecosystem degradation. To effectively address these challenges, an integrated strategy comprising four key dimensions is essential: (1) technology and innovation, such as promoting electric vehicles, smart transportation systems, and clean energy solutions; (2) policy, including carbon taxation, emission standards, and strategic planning; (3) infrastructure, such as the development of electric mass transit, multimodal transport systems, and green infrastructure; and (4) collaboration, involving public-private partnerships, ESG promotion, and community engagement. These approaches are expected to yield significant benefits across environmental, economic, social, and governance dimensions. Policy recommendations include the formulation of a national carbon reduction roadmap, establishment of financial support mechanisms, human resource development, and investment in research and innovation. The successful implementation of these strategies will enable Thailand to effectively reduce greenhouse gas emissions from the transportation sector, leading to a sustainable and competitive transport system that contributes to environmental protection, economic resilience, and improved quality of life.</p> Kawinwet Pipitthanathunyathorn Sak Kongsuwan Chalida Pohma Narongrid Yimcharoenpornsakul Copyright (c) 2025 Journal of Energy and Environment Technology of Graduate School Siam Technology College https://creativecommons.org/licenses/by-nc-nd/4.0 2025-06-30 2025-06-30 12 1 134 149
