As user-centered theory is concerned with the user and their interaction with the environment, this study will focus on the indoor environment with specificity to the IEQ (Stokols, 1992). Based on LEED v2.2 credit ratings, IEQ credits are for indoor air quality, ventilation, lighting control and comfort, thermal temperature control and comfort, and access to natural light and views (US Green Building Council, 2006). However, a review of the literature clearly shows that a number of variables affect the relationship between the user and the environment, such as aesthetics (Schell, Theorell and Saraste, 2012), ergonomics (Schell et al ., 2012), the furniture and the type of workstation (Brennan). , Chugh and Kline, 2002; Danko, Eshelman, & Hedge, 1990), acoustics (Lee, 2010; Zagreus, Huizenga, Arens, & Lehrer, 2004), privacy (Lee, 2010), and control (Lee & Brand, 2005). Veitch et al. (2003) asked office occupants to rank indoor environmental parameters and found air quality and ventilation, privacy, noise level, temperature, lighting, workstation size and access to windows from the highest to the lowest importance. However, through a literature review on the effects of the indoor environment on humans, Frontczak and Wargocki (2011) determined that comfort was of greater importance. Research into the psychosocial, physical and psychological aspects of human satisfaction and responses to environmental sustainability identifies a gap. in consistent results and between current sustainable building strategies and occupant well-being (Sorrento, 2012; Thatcher & Milner, 2012). Steemers and Manchanda (2010) establish that low levels of satisfaction with IEQ are directly correlated with low levels of health and well-being. The World Health Organization...... middle of paper ......d therefore essential to a user's satisfaction with an environment (Visher, 2008). The user experiences “the built environment as something distinct from himself, thus allowing his experience to be studied, it is part of the built environment occupied by other users, and vice versa” (Vischer, 2008, p .235).Practical significance arises from both a strategic business case that strives to increase employee job satisfaction, productivity and decreased absenteeism through identified improvements in indoor environmental factors . Additionally, the contributions will add to the evidence-based knowledge base on sustainable workplace design for interior design practitioners (Guerin and Kwon, 2010). For an interior designer, understanding and integrating measurable and important indoor environmental factors will increase IEQ and potentially occupant well-being in the workplace..
