Abstract
Precision farming is one of the important areas to ensure food security by coping with climate change and increase farmer’s productivity. Plant factory is one of the aspects of precision farming and recently sought attention among modern farmers in Malaysia. While ensuring continuous supply of crops throughout the year with increased quality and yield, plant factories consume large amount of energy to maintain their micro-climatic condition. This paper presents the energy consumption profiling of a plant factory, owned by Malaysian Agricultural Research and Development Institute (MARDI) in Serdang, Malaysia. This study is important to establish the status quo of consumption pattern of the plant factory towards reducing the energy consumption. Hence, energy audit was carried at the plant factory for duration of 2 weeks. From the audit it was found that the energy was distributed as follows: Air conditioning system - 51%, LED - 36%, pump - 3% and others - 10%. Finally, suitable energy conservation measures were proposed to reduce the energy intensity of the plant factory.
