Visual comfort considered light control methods for energy efficient office buildings: A case study

Abstract

This paper presents and investigates the performance of light control methods for energy savings with optimal visual comfort in open-plan office. By grouping personal light zone and tracking user?s location, we can provide an energy efficient light control in the office. Simulation and pilot testing results show that more than 60% energy savings could be achieved while providing recommended visual comfort level for each user. Since the proposed methods provide unprecedented energy savings, it can be said that this is a remarkable energy saving technology in the field of light control.
