Solar Classroom Ventilation
Heat stress in the classroom can make some students not to concentrate much on the lesson as they should compared to when the classroom environment is ventilated. Perhaps, this also contribute to students’ low learning outcome even when the performance objectives of the lesson are well delivered. It is advisable to install solar classroom ventilation systems to help reduce this unbearable learning environment.
The degree of heat stress varies from season to season as well as the time of the day. Similarly, heat stress intensity depends on the location and orientation of the school building. In some places, heat stress increases within the classrooms in late November to early December and mid February to March ending. From empirical investigation, during the month of March, heat stress is surprisingly dominant as early as 7:30 AM classrooms in some parts of the country. The implication of this is that it reduces the learning readiness of some students. Other students who manage to weather the storm often ask the subject teacher to grant permission for them to remain standing as a way of soothing relief. Sometimes, some students even perspire.
To minimise this unbearable atmosphere for students, you can install a solar-powered DC-driven solar classroom ventilation systems. By DC-driven, we mean powering your fans with only battries and/or solar modules without the need for a solar inverter. This reduces the cost and increases the efficiency of the system.
it is interesting to note that the time of need (or operation) of the solar classroom ventilation system by the students conveniently coincides with the hours sunshine is readily available to power the system for optimum efficiency. So, it is a wise decision to consider such system in a location where there is epileptic power supply.
