We consider the problem of controlling a smart lighting system of multiple luminaires with collocated occupancy and light sensors. The objective is to attain illumination levels higher than specified values (possibly changing over time) at the workplace by adapting dimming levels using sensor information, while minimizing energy consumption. We propose to estimate the daylight illuminance levels at...
We consider the problem of estimating lighting energy consumption in a lighting system upgrade scenario. In this scenario, a building has an existing lighting control system, denoted LCS1. We are interested in estimating the energy consumption if a more energy efficient lighting control system, denoted LCS2, had been installed. Lighting data is available from LCS2 for a specific monitored area and...
We consider the problem of quantifying energy savings when a lighting control system is upgraded. A conventional approach to determine energy savings resulting from the control upgrade is using the energy consumption values over the pre-upgrade and post-upgrade time periods. However, energy consumption depends on operational factors, such as occupancy and daylight conditions, which may be different...
