The purpose of this study was to determine the effect of the presence of live interior plants or window views of exterior green spaces on employee job satisfaction. A survey was administered through an online database. The survey included questions regarding physical work environment, the presence or absence of live interior plants, windows, exterior green spaces, environmental preferences, job satisfaction, and demographical information. About 600 office workers from Texas and the Midwest responded to the on-line workplace environment survey. Data were analyzed to compare levels of job satisfaction of employees that worked in office spaces that included live interior plants or window views of exterior green spaces and employees that worked in office environments without live plants or window views. Demographic information collected allowed controlling for salary, occupational level, educational level, age group, gender, and ethnicity. This research data can be particularly useful in urban planning, commercial property design and to encourage the incorporation of plants and green spaces in interior and exterior development projects.
