Residents in modernizing cities such as Hanoi, Vietnam have been moving to newer and well-constructed high-rise buildings. Each apartment often equipped with sliding glass windows, which are better to isolate the environment inside and outside. In the meantime, air pollution imposes long-term health risks and short-term devaluation as a desirable residence and a place to work.
New buildings seem to adequately isolate for running air conditioner and is acceptable for sound. A new question comes with arising air pollution is if such new buildings provide a safer place against pollutants such as PM2.5 and PM10.
In this study, the author conducted a 5-day continuous monitoring during a long holiday between the April and May 2019 to evaluate the efficiency of those new buildings against PM(s) from the outside environment.
