Energy savings can be implemented at different stages based on level of adoption
Stage 1 enable companies to achieve energy saving with shortest payback period by identifying quickly sub-optimal business operation with minimum investment required.
Stage 2 & 3 allows energy saving to be increased significantly usually with a payback period of 24 months or less through energy retrofitting exercises.
Stage 4 energy management automation helps to achieve total energy control and further improve energy saving by increasing operational efficiency, labour productivity and verifiable corporate social responsibility reporting.
Stage 5 involve higher investment into high energy efficient machinery and equipment including HVAC system to achieve a holistic energy saving plan
