Abstract

The general aim is to study the pattern of energy consumption of a building by relying on the Internet of Thing (IoT) method available and the effect of Coefficient of Performance (COP) to energy consumption. According to the literature review, the heating ventilation air conditioning (HVAC) system in a building contribute to almost 60 percent of energy consumption usage in a building. Growing concern over the HCAV system effect has initiated the pursuing energy-efficient in Universiti Teknikal Malaysia Melaka (UTeM) with energy policies implementation. The result of energy consumption has been obtained for six (6) month to identify the pattern and the maximum demand usage. The highest energy consumption recorded in November 2019 is 110808.59 kWh with maximum demand 357.33 kW while for the highest maximum demand is recorded in September with 368.06 kW at 89313.75 kWh energy consumption. The coefficient of performance (COP) in the chiller shows the maximum in 22/8/2019 at 4.7 with energy consumption of 3733 kWh. On top of that, for the highest energy consumption is on 22/8/2019 with 4878.87 kWh of energy consumption. Besides, the increment of 1.6 COP can save 23.49 percent of the energy consumption of the building. The study concludes that the Internet of Thing (IoT) method achieved the desired state in collecting and presenting the pattern of the energy consumption at the building. Finally, the relationship has been resolute where the coefficient of performance (COP) of the chiller is inversely proportional to the energy consumption. Hence, the research confirms that the coefficient of performance (COP) affect energy consumption significantly as concluded
