A randomised field experiment to test the restorative properties of purpose-built biophilic “regeneration pods”

Abstract

Purpose There has been limited investigation into how “biophilic design” (i.e. the integration of nature within the built environment) can be effectively used within the workplace to facilitate the process of psychological restoration. The purpose of this study was to focus, in particular, on the effectiveness of biophilic “restoration pods” in promoting recovery from stress. Design/methodology/approach A randomised field experiment was conducted. A total of 32 employees from a participating organisation completed two tests replicating typical office work (proofreading and arithmetic) and subjective ratings of stress, anxiety and task-load both before and after a 10-minute micro-break, taken in either the regeneration pods (treatment group) or an ordinary meeting room (control group). Findings The results showed that participants who took their break in the regeneration pod reported lower post-break anxiety and perceived task-load, and higher post-break arithmetic task performance, than the control group. Practical implications The findings suggest that purpose-built spaces for restoration within office buildings will be effective for helping employees to proactively manage their stress levels while at work. Biophilic design principles will enhance the effectiveness of these spaces, and this does not necessarily need to involve direct exposure to plants or views of nature. Originality/value To the best of the authors’ knowledge, this is the first randomised field experiment to test the effectiveness of a purpose-built space for restoration within offices. Additionally, this paper explores different forms of biophilic design than previous studies.
