| Abstract | This study aimed to estimate reduction of electricity consumption and cost with renewable energy and without renewable energy consideration.Renewable energy consideration was only referred to rooftop PV systems which were assumed to locate on the top of energy building, administration building and a faculty residence at AIT. The reductions without renewable energy consideration were estimated by tariff change, energy efficiency and conservation.As tariff change at AIT, AIT could save electricity bill by changing a large general service to a non-profit organization. In 2015, the saving was 149,149 Baht in January, and was 98,943 Baht in February. In 2015, electricity charge at AIT could be saved by rooftop PV systems. Different capacity of PV rooftop systems could allocated on the top of energy building 1, administration building and the faculty residence.Total capacity 132.6 kWp of rooftop PV systems could generate electricity on-site about 244.3 MWh, and mitigate CO2 emission about 218,468 kg CO2eq in 2015. 132.6kWp of rooftop PV systems on three buildings totally could reduce electricity consumption and charge at AIT by 2.25% in 2015.In addition, the payback period of rooftop PV systems could be 8.7 years at energy faculty, 8.3 years at administration building and 10.8 years at the faculty residence.Energy efficiency and energy conservation could reduce electricity consumption and charge as well. At library, fluorescent tubes T5 replacement could save 29,578 kWh of electricity consumption,18,022 kg CO2eq of CO2 emission and 92,455 Baht of electricity charge per year. The payback period for T5 replace ment could be 1.52 years. LEDtubes T8 replacement could save 59,156 kWh of electricity consumption,36,044 kg CO2eq of CO2 emission and 184,909.3 Baht of electricity charge per year. The payback period for LED T8 replacement could be 1.56 years which was more attractive. Moreover, use of pull switches could contribute more savings and quicker payback period.Moreover, real-time electricity monitoring system was installed at the faculty residence within AIT campus to study on pattern use of electricity and find opportunities to reduce electricity consumption. Residents at this faculty residence has awareness of using electricity in that most efficient appliances were used. Electricity consumption percapita of this residence in 2015 was quadruple lower than an average of Thailand in 2014. Thus, use of electricity at this faculty residence was efficient. |
