Energy Savings of Smart Lighting Systems in Office Buildings Yongxing Lu 1, Wenjing Yang

Abstract

Lighting energy consumption is a primary component of office building energy expenditure. Intelligent lighting systems have attracted significant attention for their potential to reduce energy consumption. This study conducts a scoping review of energy-saving research on smart lighting systems in office buildings to determine the field’s scope, the primary technologies and methods employed, specific energy-saving outcomes, and existing research gaps. Using predefined search terms across Web of Science and Scopus databases, we retrieved related publications from 2010 to 2024. After screening titles and abstracts, 79 relevant studies were included for analysis. The review reveals significant energy-saving potential for smart lighting systems in office buildings. However, research methodologies and reported energy savings vary considerably, and studies generally lack in-depth analysis of user behavior and the return on investment of systems. Future research should focus on developing more intelligent and adaptive lighting control strategies, whilst comprehensively evaluating both user behavioral preferences and the long-term economic benefits of the system.
