This paper presents the potential of generating electricity with rooftop solar energy and conserving energy by changing the equipment of Chaiyaphum Rajabhat University by surveying energy use in Chaiyaphum Rajabhat University. Information regarding building space was collected, including several air conditioning equipment, several lighting equipment, and information on electrical energy usage of Chaiyaphum Rajabhat University. Then the potential for rooftop solar installations, energy saving potential in lighting systems, and energy saving potential of air conditioning systems proceeded.
As a results, it was found that it was possible to reduce the overall energy cost burden by more than 48.60% from the energy cost compared to before changing the system to the LED system with Built-in IoT. This resulted in reducing 90% energy consumption and 37.50% reduced energy use of Inverter Air Conditioner. Electricity production from solar energy installed on the roof can be designed with a maximum power generation capacity of approximately 450 kWp, resulting in electrical energy savings of 668,172.59 kWh, equivalent to an amount saved of 3,006,766.66 bath/year.
