In the past decades, numerous post-occupancy studies have been conducted to investigate green building occupant satisfaction in different regions however, a systematic review of these studies is still lacking. This reinforces the importance of occupant perspectives in evaluating the overall performance of green buildings. Since employee related costs account for the largest operating costs among all business expenses, including energy bills and rental cost occupant satisfaction, thus, is of great importance for many organisations particularly in commercial and institutional office environments, to enhance overall performance and profitability. Occupant satisfaction has further been correlated with turnover intentions, and retaining talented and skilled workforces (Van Dick et al., 2004).

Research has shown that satisfaction with working environments increases job satisfaction and thus, elevates employee work performance and productivity (Veitch, Charles, Farley, & Newsham, 2007). Occupant experience and satisfaction are influenced by several environmental factors such as thermal, visual, acoustics and air quality, as well as workplace features such as privacy, furniture, needs, cleanliness, and environmental controls (Altomonte & Schiavon, 2013, Geng, Ji, Lin, & Zhu, 2017). However, a contradictory body of knowledge regarding the impact of green buildings on occupant satisfaction has been discussed in earlier studies as a result of varying research methods and measures (Thatcher & Milner, 2016). For commercial organisations and institutions, employee satisfaction and experience are as important as reducing the negative impact of buildings on the environment when investing in green buildings and green certifications. These tools have shown their popularity in the real estate market however, their role in improving occupant experience in green buildings remains uncertain (Altomonte, Saadouni, & Schiavon, 2016, Gou, Prasad, & Siu-Yu Lau, 2013). These green tools use credit rating systems to rank green building achievements and performance (Roderick, McEwan, Wheatley, & Alonso, 2009). BREEAM, Australia Green Star, South Korea G-SEED, and China's GBL have been initiated to accelerate the transformation of the building sector towards an environmentally friendly model. Many green building rating tools, such as U.S. Energy Information Administration, 2003). Green buildings refer to a practice in the building industry that prioritises environmental responsibility and resource efficiency in a whole building life cycle (U.S. This paper contributes to the understanding of socio-economic factors underlying green building occupant satisfaction, and also provides evidence for commercial and institutional sectors, where green buildings are used to improve employee satisfaction. and U.K.), where no significant differences were found on occupant satisfaction between green and non-green buildings, and the Orient (mainly China and South Korea), where green building occupants showed significantly higher satisfaction compared to non-green building occupants. In spite of the inconsistency and inconclusiveness, this study identifies two global contexts: the Occident (mainly U.S. Sample size, occupancy period and green features are discussed as the main bias accounting for the inconsistency of the global evidence. The evidence on green buildings outperforming non-green counterparts is inconclusive. The performance of green buildings in terms of occupant satisfaction appeared to be inconsistent, varying from study to study. This study reviews the global evidence to examine whether green buildings are more satisfactory than non-green buildings. In the past decades, numerous post-occupancy studies have been conducted to investigate green building occupant satisfaction in different regions however, a systematic review of these studies is lacking. The former relies on technical advancement, while the latter needs empirical evidence. Green buildings not just help to reduce energy and resource consumption, but also to improve user experience and satisfaction.
