Abstract
Construction works is abundant in Singapore and in this land-scarce country, the government wishes to practice sustainable development so that the citizens can continue to enjoy economic growth and high quality of life. In light of this sustainable direction the government is embarking on, new ideas have been manifested in the form of green roofs and walls.
Much has been researched upon regarding the thermal and acoustic benefits of green walls and vertical greenery. This report aims to investigate the impact green walls have on the indoor air quality and see how it will affect building occupants.
It is hypothesized that by introducing plants to an indoor environment, the air quality would improve. For the purpose of this report, an experiment was conducted to test this hypothesis by measuring the following parameters: fungi, bacteria, carbon dioxide, volatile organic compound, temperature and humidity, in a chamber before and after the installation of a green wall.
A positive finding was desired so to persuade corporations to include a green wall in the design of a facility for the betterment of the building occupants. However, the findings from the experiment were mixed. The presence of fungi and bacteria increased while CO2, VOC and humidity levels decreased. Temperature seems unaffected by the wall. It was concluded that from this experiment, indoor air quality improves to some extent with the introduction of a green wall though further research is needed.
With proper maintenance, the study has shown that green walls will improve the indoor air quality and consequently the health and productivity levels of the building occupants, while adding aesthetic value to the surroundings. Hence it would be feasible to include green walls in the design of facilities.
