Report says better indoor air quality in offices can lead to productivity increases of 8-11%

A ground breaking report from the World Green Building Council finds overwhelming evidence of Indoor Air Quality and its impact on the health, wellbeing and productivity of staff. The Report, Health, Wellbeing and Productivity in Offices: The Next Chapter for Green Building, presents overwhelming evidence that office design significantly impacts the health, wellbeing and productivity of staff. It finds a range of factors – from air quality and lighting, to views of nature and interior layout – can affect the health, satisfaction and job performance of office workers.

Findings of the report include:

Indoor air quality: A comprehensive body of research suggests that better indoor air quality (low concentrations of CO2 and pollutants and high ventilation rates) can lead to productivity improvements of 8-11%.

Thermal comfort: Research demonstrates that thermal comfort has a significant impact on workplace satisfaction and modest degrees of personal control over thermal comfort can return single digit improvements in productivity.

Lighting and views of nature: Several studies have estimated productivity gains as a result of proximity to windows, with experts now thinking that views from windows are probably the more significant factor, particularly where the view offers a connection to nature.

Noise and acoustics: Research suggests that being productive in the modern knowledge-based office is practically impossible when noise provides an unwanted distraction. This can be a major cause of dissatisfaction amongst occupants.

Interior layout: The way the interior of an office is configured (including workstation density and configuration of work space, breakout space and social space) has been found to have an impact on concentration, collaboration, confidentiality and creativity.

Active design and exercise: Health can be improved through exercise, and so active design within a building, and access to services and amenities such as gyms, bicycle storage and green space can help to encourage healthier lifestyles of building occupants.

There is also a Toolkit to measure health, wellbeing and productivity:

Financial metrics: Absenteeism, staff turnover, revenue breakdown (by department or per building), medical costs and complaints, and physical complaints.

Perceptual metrics: Studies which test a range of self-reported attitudes into health, wellbeing and productivity in the workplace can contain a wealth of information for improving office performance.

Physical metrics: Direct measures of the physical office environment, such as temperature, are key to measuring the effect on the health, wellbeing and productivity of workers. Exciting developments in this area such as portable and wearable technology are likely to substantially expand our understanding.

There are some simple measures that employers can do to improve air quality in the workplace and protect the health and wellbeing of employees: Portable Workplace Air Cleaners are well suited to improve indoor air quality in offices.
