Abstract
This study aimed to evaluate the performance and effectiveness of a sensor-based, re-mote-controlled ventilation system in improving indoor air quality, safety, and overall student well-being in welding laboratories at Cebu Technological University – Pinamungajan Campus. Using a mixed-method research design, both quantitative and qualitative data were collected from students, faculty members, and maintenance personnel through surveys, interviews, and direct observations. The study assessed key variables including ventilation efficiency, pollutant reduction, thermal comfort, health effects, and cost-efficiency of the system. Findings revealed that the installation of the remote-controlled exhaust fan significantly enhanced air circulation, resulting in reduced exposure to hazardous fumes, improved temperature regulation, and better control of indoor pollutants such as smoke and carbon dioxide. Participants reported noticeable improvements in comfort, reduced health-related issues such as headaches and respiratory discomfort, and increased focus and productivity during laboratory activities. The system also contributed to improved attendance and engagement among students by creating a healthier and more conducive learning environment. Moreover, the integration of sensor-based automation and remote functionality enabled efficient energy consumption by allowing the system to operate only when necessary. The Do-It-Yourself (DIY) design proved to be a cost-effective alternative to commercial ventilation systems while maintaining reliable performance and safety standards. Overall, the study highlights the importance of adopting affordable, technology-driven ventilation solutions in educational settings. It demonstrates that smart ventilation systems can significantly enhance environmental quality, support student health, and promote sustainable and efficient campus operations.
