The Effects of Live Plants and Windows In Interior Spaces On Space Usage and Stress Levels of Users

The main objective of this study was to examine the effects of live plants and windows in interior spaces on space usage and stress levels of users. Sites were selected based on their accessibility to the general population, their expanse of space in that multiple students, faculty, and staff could use the space at once, and their general use, meaning that no other resources were available besides seating and tables, such as computers and/or access to food/drink sales. Multiple campus sites were used including those at the university library, and areas of the business building. Assortments of interior plants were used based on their aesthetic features, durability, and light and water requirements. Plants were rotated in and out of the study sites on a two-week schedule. Observations were taken weekly to tally where students were active in each of the study areas and the type of activities in which they were participating. Observations occurred during high traffic times based on catalog course scheduling. Stress measuring questionnaires were administered every week to students that were active in test sites. Results demonstrate the value of interiorscaping in creating comfortable work and study environments. Results also help to provide evidence in the value of plants in reducing stress.
