Today LED lighting is increasingly common in commercial buildings, but lighting control is still often done by timers (or not at all). The future of energy efficient lighting is intelligent control based on multiple inputs such as motion sensing and time of day. However, with dynamic operation, calculating the energy savings and payback period is much more challenging than under a fixed operating schedule.
Ampotech's power monitoring solutions can provide visibility into specific lighting zones and even lighting circuits that have been retrofitted to tell you exactly how much you're saving. At the PROTIOTYPE Design Science Community's intelligent interior showcase at Singapore Polytechnic, Ampotech is monitoring the performance of intelligent lighting for two zones.
The image above shows the power consumption of both zones during the course of a typical weekday. In January 2018, the system reduced energy use by over 60% compared to fixed on/off timers.
