If we measure the effects of implementing elements and methods of biophilic design, using workplace and employee surveys, we can gain qualitative measures of what has improved in the space and which aspects of the design have successfully done their job.
Ultimately, the benefits of biophilic design are measured by the quality of life provided to the end-user in each workspace. There is no one size fits all. A bespoke set of methods is required which will depend on the given space and architectural elements.
