Hypothesis
The air quality inside the room will be influenced by various factors, including the effectiveness of the ventilation system, the overall number of residents, and the presence of pollutants such as dust, allergens, and volatile organic compounds (VOCs). Based on these parameters, the air quality in the apartment will improve when ventilation is increased, allowing for the removal of pollutants and reducing the number of residents who generate additional pollutants.
Methodology
To study the air quality inside the room, I will employ a straightforward measurement technique utilizing a sheet of paper and a fan. By placing a sheet of paper in various locations in the apartment and observing its movement when the fan is activated, I can gauge the presence and flow of air; this practice is commonly used (Cheung et al. 109640). This method will offer valuable insights into the effectiveness of ventilation, allowing me to assess the air quality within the apartment.
Parameters
To measure the necessary metrics, certain relevant parameters must be reviewed. Firstly, this is the time of measurement; I will check the metrics at different times of the day to capture variations in air quality. Secondly, I should consider the interior conditions; I will record the levels of temperature and humidity inside the rooms using a thermometer and a hygrometer. Thirdly, I need to control exterior factors; I will note the weather conditions and take into account temperature, humidity, and sunlight, utilizing a weather app or simple online forecast. Finally, I will utilize a portable air quality monitor, which will help control the levels of pollutants such as particulate matter (PM2.5), VOCs, and carbon dioxide (CO2) inside the apartment.
Results
Quantitative Results
According to the quantitative outcomes obtained, the average temperature inside the room was 23°C, with variations ranging from 21°C to 25°C. The average humidity parameter recorded during the observation was 45%, with the indicators ranging from 40% to 50%. The PM2.5 levels ranged from 10 to 20 μg/m3, indicating moderate air quality. VOCs levels complied with acceptable limits, and CO2 levels ranged from 400 to 800 ppm.
Qualitative Explanation
The movement of the sheet of paper confirmed that the ventilation within the apartment was adequate since the paper fluttered consistently when the fan was turned on. The air quality monitor indicated that the rooms had moderate air quality, with the proportion of pollutants within the permissible concentration. The levels of temperature and humidity were comfortable, contributing to the overall comfort of staying in the apartment.
Conclusion
Based on the analysis, the apartment has satisfactory air quality, ventilation, and comfort levels. The simple measurement technique using a sheet of paper and a fan provided valuable insights into the air movement within the room. Portable monitors that control pollutant levels may be useful for checking the necessary parameters. Nonetheless, one should recognize that this is not a comprehensive analysis and should be supplemented with more detailed measurements to gain a thorough understanding of the building’s performance. The table in Appendix conveniently summarizes the recorded data.
