Analysis Of Energy Usage In Pusat Persatuan Pelajar

Energy analysis is important in resolving energy consuming modality,due to observing how the energy utilized has shifted with time in the building and how the arrangement elements interrelate with each other.In this case study,a preliminary energy audit is done on the existing indoor parameters.The study was conducted at Pusat Persatuan Pelajar (PPP),Universiti Teknikal Malaysia (UTeM).The project is aimed at comparing the lighting index between PPP building and the current Malaysian standard (Malaysian Standard 1525:2014).This undertaking is also aimed at evaluating and analyzing energy used in the PPP building.To calculate the electricity consumption and lighting,physical indoor data was collected through a clamp meter and lux meter on three floors in the PPP building.The air-conditioning system in the selected rooms was left for one hour before starting the measurements.The lighting data was collected between 10 am to 12 pm and again 2 pm to 4 pm with a gap of 20 minutes for each reading.The results show indicated that the energy consumption of the air-conditioning system was 11157.76 kWh and cost-ing RM 4072.58 per month.From lighting system analysis, the energy consumption was 6600.16 kWh and costing RM 2409.05 per month.The project also studies the current lighting system and a proposed energy retrofit to save energy usage.After proposing ret-rofit plan,the energy consumption can be saved 18931 kWh per month and RM 1105.57 per month.The difference of power consumption for a month March in 2017 between the measurements and electricity bill analysis is about 5%.Since the difference is too small, therefore,it can be concluded that the obtained the Building Energy Index (BEI) value in the project is reliable.Most of the lighting levels in every audited zone exceed Malaysian Standard MS 1525:2014.In addition,the Building Energy Index (BEI) for all the building is 233.67kWh/m²/year and for each level is 77.89 kWh/m²/year.The best BEI exercise and recommended by Malaysian Standard is 135kWh/m²/year
