Impacts of multi-sensory design on the employee’s well-being; an experimental study of selected it offices in Colombo district

Abstract

Multisensory architecture, which impacts occupants by stimulating their senses, is underexplored in workplace settings, where individuals spend most of their time. This study addresses the gap by examining the combined influence of visual and auditory elements on employee well-being using a 3D simulated model of an IT office in Colombo. Four scenarios were created for 20 employees to test these sensory elements. This research emphasizes the importance of selecting design elements that engage multiple senses without causing sensory incongruence. Integrating multisensory design in workplaces can boost employee well-being, improve work quality, and benefit financial and health outcomes. Findings reveal that sensory interventions significantly enhance psychological well-being: Control (62.2%), Green Wall (86%), Calming Music (70.33%), and Combined (78.9%). Nature-related elements were preferred, with the green wall scoring highest (86%) and 40% favouring nature sounds. However, combined sensory elements scored lower than the green wall alone, highlighting the need for sensory harmony. Employers, designers, and relevant authorities should consider these findings to foster a vibrant and enriching work environment that supports the psychological health and productivity of employees. By doing so, workplaces can become more engaging and supportive spaces.
