Human Assets:  Generally speaking, the cost of human assets to a company is significant. The cost of the personnel assets is estimated at 10 X Total Building Operating Costs,  and 10 X Total Energy Costs of a workplace setting.
Research shows that the following improves with interior plantscapes:
Employee Reaction Times – Improved 12% in tests with measured stress responses

In stressful situations:

Visual Access to Plant Settings produces significant recovery from stress within five minutes.
(Research: Dr. Richard Ulrich, Texas A&M University)

Employee Satisfaction – Employees frequently have a “Green Thumb Passion”

Studies have shown that the indoor work environment is important at many different levels, especially in worker productivity. (ASID-The Impact of Interior Design on the Bottom Line. )

In fact, the American Society of Training & Development says “Companies are focusing on the physical workplace as a key component of their corporate strategy to improve productivity. (” ASID-The Impact of Interior Design on the Bottom Line.)
Research has found that: “Office workers are more likely, and willing to log an extra hour per day given the right workplace designs.”  (The Gensler 2006 U.S. Workplace Survey )

“The effect of office design on companies’ bottom line for worker productivity in the U.S. is estimated to be at least $330 billion annually.” (The Gensler 2006 U.S. Workplace Survey

Efficiency:  Under controlled conditions, people working in a windowless college computer lab reacted 12% faster to computer tasks, were less stressed (lower blood pressure) and felt more attentive than those working in a room with no plants.  (Source: Lohr, V.I., C.H. Pearson-Mims, and G.K. Goodwin. Journal of Environmental Horticulture 14(2):97-100

Improved Thinking Capacity:  In an 8 month study, men and women exhibited more innovative thinking in workplace settings that included plants and flowers.

Men generated 15% more ideas when plants were present.

Women generated better ideas! (more creative, flexible solutions to problems.)

Workers who spend at least 4 hours per day on a computer showed a significant improvement in efficiency and concentration when plants were present. (Source: Berg, J. A.; Constructing for people – perception of the quality of the working environment )

Reaction Time:  Research also shows that we have 12% quicker reaction rate on computer tests, when plants are present in the room. We are more productive!  (Source: Lohr, V.I., C.H. Pearson-Mims, and G.K. Goodwin. Journal of Environmental Horticulture 14(2):97-100

Indoor plants can Improve Our Health!

Indoor plants can help reduce absenteeism.  A workplace well-being study shows in offices without plants workers were absent 3.6 days because of poor air quality complaints.

Common Office Chemical Emissions:
Formaldehyde, xylene, benzene, chloroform, ammonia, acetone and others (Emissions come from ceiling tiles, copy machines, particleboard, carpeting materials, computers… and more of our common components of an office setting.

In a two year study in 51 offices, health symptoms were 23% less in offices with plants.  (Source: Fjeld, T., et al. “Effect of Indoor Foliage Plants on Health and Discomfort Symptoms Among Office Workers,” )

The #1 office toxin, formaldehyde, was rapidly eliminated by commonly used office plants. (Source: Wood, R. A., et al. “Study of Absorption of VOCs by Commonly Used Indoor Plants” )


Plants Cost Less than Most Corporate Décor Items –
Yet the Workplace is Perceived as More Expensive-Looking with Effective Interiorscaping.


The following research facilities, and many more,
have done significant research on the effective use
of plants in office environments:
