Overcoming indoor air pollutants by using wall gardens-carbon dioxide study case

Abstract EN

This study reviews the effect of indoor plants on overcoming indoor air pollutants like CO2 when using wall garden
units planted with Syngonium and Pothus in different arrangements as an indoor decorative unit which can be used in
closed work places.

This study was taken at Bibliotheca Alexandrina back offices where employees are subjected to all of
the indoor workspace conditions during their work hours.

Eight identical offices were chosen where six wall gardens were
installed and the pollutants were monitored for 13 weeks, and a questionnaire was given to the employees.

It was found
that introducing wall gardens to indoor closed workspace not only reduced some of the pollutants values but also had
positive effects on the employees.

Another prospective for this study was to spread the idea of the importance of green
plants in our lives in a simple way that can reach those who got no back ground about plants, also it was a target to create
the most appealing and on budget methods for setting indoor gardens as people pay more attention to indoor construction
and decoration at the lowest cost and most appealing shapes, in order to encourage people who find themselves locked
indoor in their homes and at workspace for more than six hours every day and accordingly exposed to all the indoor
pollutants due to the unavoidable synthetic materials and furnishings products used in these buildings that are sources of
air pollutants to install their own wall gardens by themselves or by specialized companies.

Pothus and Syngonium were
planted in wall gardens and the readings of CO2 were taken on daily bases using Fluke 975 AirMeter™ to monitor Carbon
dioxide, the device is owned by the Engineering Sector of Bibliotheca Alexandrina and calibrated on 2016.
