PM 2.5 Reduction by Installation of Facade with Broad Leaf and Narrow Leaf Plant
Keywords:
Facade, PM 2.5, Broad leaf plant, Narrow leaf plant, Green facadeAbstract
PM 2.5 has been an important issue for living in a city due to its negative health impact. PM 2.5 reduction by green facade was studied in this experiment. The steel facade with 3.70 x 2.50 m was installed at the front of the model room which located near the 4 lanes road. Broad leaf and narrow leaf plant as Epipremnum aureum and Chlorophytum comosum were attached to the facade for 2 weeks. The inside and outside air quality of the model room as PM 2.5, temperature, relative humidity were hourly observed. The result showed that the installation of a facade or green facade could significantly reduce PM 2.5 and heat through the model room via shading and plant evapotranspiration. Both Epipremnum aureum and Chlorophytum comosum gave better PM 2.5 reduction than
steel facade which corresponding to the leaf area index (LAI) during the experiment.
