Workplace plants reduce absenteeism by 20 per cent, increase humidity by an average of 5 per cent, and significantly improve the psychological well-being of employees. This is demonstrated by scientific research conducted by Wageningen University. Furthermore, employees rate a green working environment as 26 per cent more attractive.

Scientific Research Into Green Working Environments

The study by Wageningen Environmental Research was carried out in collaboration with Fytagoras and other partners. Researchers studied the effects of plants within corporate offices and healthcare institutions. Special sensors were placed in the monitored rooms to accurately determine physical differences in the indoor climate.

Before and after the introduction of the plants, employees shared their feedback regarding the workplace, indoor climate, office atmosphere, and their own health. In addition, concentration tests were conducted and levels of the stress hormone cortisol were measured. The results show that a space without plants is less inviting. The presence of greenery substantially improves both the physical and mental well-being of employees.

The 6 Key Benefits of Workplace Plants

The research highlights six clear advantages for your office design:

  • Improved humidity: In rooms with plants, relative humidity is an average of 5% higher. In winter, this difference rises to as much as 17%.
  • Enhanced thermal comfort: Employees are less likely to perceive the temperature in a green environment as too hot or too cold.
  • A more attractive workplace: Employees rate a working environment with plants as 26% more appealing.
  • A more positive mindset: Following the introduction of greenery, employees feel more positive and worry less about work.
  • Greater job satisfaction: With the arrival of plants, employees express higher satisfaction with their own performance. They also perceive that their employer shares this view.
  • Reduced absenteeism: Working in a green space leads to a 20% drop in sick leave. This equates to an average of 1.6 fewer sick days per employee each year.

The Economic and Financial Benefits for Your Business

Investing in the purchase and care of indoor plants requires an initial outlay, but this is typically recalculated or recouped within a single year. This return on investment is driven by the drop in absenteeism and the boost in employee performance.

Additionally, greenery helps reduce your energy costs. Plants increase humidity and naturally cool spaces during hot summer months, thereby reducing the reliance on air conditioning.
