This review article (2015), by a Harvard University based research group, examined the current evidence on green building design as it relates to indoor environmental quality (IEQ) and human health.

From the scientific evidence published to date, their findings indicate:

• Green buildings have better measured and perceived (IEQ) compared to non-green buildings

This has direct benefits to the health and wellness of occupants, with evidence suggesting:

• Fewer sick building syndrome symptoms, fewer respiratory symptoms, better physical and mental health and improved work productivity

The researchers did find however, that much of the data was reliant on non-robust and indirect subjective measures of health. They propose a more robust and objective framework of 'Health Performance Indicators' for use in future studies of buildings and health.
