The Air We Breathe
No one likes to work in an unpleasant atmosphere.
Lorraine Gourlay takes a look at some easy ways to improve the office
environment. One of the most important aspects of keeping a company
running smoothly is a happy employee. If your employees are not
happy in their working environment, this can lead to poor performance,
a decrease in productivity and an increase in days off sick. One
of the reasons for this can be Sick Building Syndrome.
Sick Building Syndrome
Toxins in an office environment cause Sick Building Syndrome. New
or recently renovated buildings have a higher risk due to the large
amounts of chemicals produced from paint, carpets and furniture
- these can be detected for up to a year afterwards. New “energy
efficient” buildings are also a risk, as these recirculate
fumes. All offices create toxins by using the very products we need
to keep our businesses running smoothly - copiers, printers, PCs.
All these products give off some form of toxins and pollutants.
Workers are not even safe from the products used to clean
offices - these too are a cause for concern. All these pollutants
start to play havoc on immune systems, causing sore heads, runny
noses, sneezing and breathing problems which can all lead to poorer
performance in the workplace and more time off sick.
How can we prevent this? Unfortunately, until manufacturers can
create entirely environmentally-friendly materials, this cannot
be avoided. However, it is possible to combat the effects these
toxins have in the environment by using plants. As simple as this
sounds, plants have been proven to help “clean the air”
of toxins. Dr. Wolverton, a researcher at NASA, has carried out
intensive research into the subject involving the three major indoor
pollutants:
- Trichloroethylene
- Benzene
- Formaldehyde
Wolverton found that most indoor plants remove at least one type
of toxin, although most of them are not able to absorb high levels
of all three. The toxins that are absorbed do not damage the
plants. The toxins are absorbed into the root zone of the plants
where they are turned into nutrients. By increasing the soil volume,
this in turn improves the plant’s rate of absorption.
The findings also discovered that spider plants were the most
productive at improving air quality in rooms. Ivy, dragon trees
(dracena marginatas) and rubber plants were also effective. The
research findings recommended the following:
- At least one plant per 9.29 square metres
- Combine plants to combat a range of toxins
- Select leafy plants - the more surface area a plant has, the
more air it can
clean
- Each worker should have a plant on his or her desk, within the
“personal breathing space” - an area of six to eight
cubic feet (sqm) where most of the working day is spent.
Plants have also been shown to relieve stress. Research carried
out by Surrey University environmental scientist Helen Russell showed
that plants helped to create a more relaxed atmosphere and eventually
led to a 60 percent drop in absenteeism. In other tests, carried
out by Professor Virginia Lohr of Washington State University, those
people with a plant on their desk showed 12 percent faster reactions
and their stress levels were reduced dramatically.
Where to start?
Before you start looking at plants and suppliers, there are a number
of points to consider:
- What is your budget?
- Do you want to buy the plants yourself or outsource this task?
- Who will maintain the plants (i.e. will it be done internally
or by a contractor?)
- What sort of plants do you want?
- Where will plants be located?
Once you have considered these points, you may decide you have
enough information to obtain and care for the plants yourself. Alternatively,
the project can be outsourced to an interior landscape company.
Interior landscaping companies will carry out a survey of your premises
and discuss what benefits you wish to gain from having plants in
the office. As well as reducing the toxins in the air, the proper
placement of plants can lower heating and cooling costs and reduce
noise in open plan areas.
It is often possible to rent plants from a landscaping company
instead of buying them. The benefits are that the plants can be
changed either seasonally or annually, and the landscaping company
will maintain the plants. Most will offer a maintenance/replacement
service, with no additional cost for replacement plants. However,
it is worth researching a few companies and comparing what services
are available and what costs are involved.
Many companies also offer artificial landscaping services. This
will not give the health benefits, although it will brighten up
the office and make the surroundings more attractive for both visitors
and employees.

OFFICE ENVIRONMENT
A two-year study in an office, conducted by Professor Tove Fjeld
of the Agricultural University in Oslo, found the following reductions
in ailments after the introduction of plants:
Ailment |
% Reduction |
Fatigue
Headache
Sore/dry throats
Coughs
Dry facial skin |

Fjeld also carried out studies in a school and an x-ray department
with similar results, concluding that plants reduce minor ailments
associated with Sick Building Syndrome.
HOW TO CHOOSE THE RIGHT PLANTS
Select indoor plants that require lots of watering, says Dr. Ronald
Wood. These are the best for improving humidity levels and tend
to have an active metabolism that is helpful in breaking down pollutants.
Also, use plant varieties with a high leaf area per size of pot.
The bigger the surface area, the more it can absorb pollutants and
chemicals.
