The World Green Building Council's report Doing Right by Planet and People: The Business Case for Health and Wellbeing in Green Building urges companies to make green improvements by highlighting the tangible economic benefits of green building and showcasing improved occupant satisfaction when companies implement new health, wellbeing and productivity features in existing green structures. The report examines case studies of 11 facilities around the globe that have one or more green certifications including LEED, Green Star and BREEAM. The report evaluates health and wellbeing features that were integrated into the facilities, such as: enhanced fresh air ventilation, acoustic privacy, increase of daylight penetration and use of biophilic design elements such as green walls and extensive indoor plants.
