In a significant development for sustainable energy practices in Cameroon, a recent study published in the ‘Journal of Engineering’ reveals the potential of daylighting to reduce electrical energy consumption in public school classrooms. Led by Merimé Souffo Tagueu from the Department of Physics, the research addresses a pressing issue: the growing demand for electrical energy in Cameroon, which is not being met by current supply capabilities.
The study introduces an innovative method that leverages both natural and artificial lighting to optimize energy use. By employing a dimmer system, the team was able to adjust the luminance levels of classroom lights, ranging from 0% to 100%, while adhering to regulatory standards. This approach not only enhances the learning environment but also significantly cuts down on energy costs. “Our findings indicate that by optimizing the balance between natural daylight and artificial illumination, we can achieve an impressive 57.85% reduction in energy consumption,” Tagueu explained.
The methodology involved an extensive analysis of illuminance levels within a classroom, which was divided into 99 measurement points. Utilizing DIALux software for simulations and direct measurements with a luxmeter, the researchers ensured that the average illuminance level met the EN12464 standard of 300 lux. This meticulous approach showcases the potential for daylighting solutions to alleviate energy deficits, particularly useful in a nation where new power plants take considerable time and investment to construct.
The implications of this research extend far beyond the classroom. For the construction sector, the adoption of daylighting strategies could revolutionize building design, driving a shift towards more energy-efficient structures. Architects and builders could integrate these findings into their projects, not only to comply with energy regulations but also to enhance the marketability of their developments. As Tagueu noted, “This solution could serve as a bridge, allowing us to manage our current energy challenges while we work towards long-term infrastructure solutions.”
As the construction industry increasingly focuses on sustainability, the insights from this study could inspire new design paradigms that prioritize natural light, ultimately leading to reduced operational costs and a smaller carbon footprint. The research highlights a viable path forward, where immediate energy savings can be realized while simultaneously paving the way for a more sustainable future.
