“…The velocity contours around the patient at the two heights of 0.9 m and 1 m are shown in Figure 7. The average velocity, for all strategies at the height of 1 m near the patient, was less than 0.25 m/s, which is the recommended value [27]. In addition, at the height of 0.9 m, the velocities for strategies 1 and 2 were less than the recommended value.…”

“…According to the occupational safety and health administration (OSHA), the maximum contaminant of CO 2 in indoor air is equal to 1000 ppm [27,36]. In this study, carbon dioxide concentration was measured inside the room using four sampling points (P1, P2, P3, and P4) by a computerized system.…”

“…Additionally, one of the solutions used to protect children from the coronavirus is the use of activated carbon filters [26]. Finally, during the isolation room design for respiratory diseases, environmental conditions should be considered, such as the velocity around the patient not exceeding 0.25 m/s and carbon dioxide less than 1000 ppm [27].…”

Since the emergence of the COVID-19 pandemic, complications for healthcare workers in hospitals have increased. Healthcare workers have had to develop innovative solutions to deal with the shortage of resources and isolation rooms for those infected with the coronavirus. One of the solutions used is to convert the general patient room into a negative pressure room to prevent airborne infections from leaking into the surrounding environment. However, this was not always easy due to many limitations, such as the overall design of the chamber and the unavailability of mechanical parts to create negative pressure. Another solution is to use medical masks. However, they are not appropriate, especially for patients who suffer from breath shortness. With all these problems, a simple solution was reached in the present work, which is to create a portable isolation room that is simple in terms of cost and implementation. The objective was to investigate the dispersion of the infection inside the portable chamber in addition to its effectiveness in minimizing the risk of infection for healthcare workers. Thus, the airborne infection is eliminated by connecting the exit of the portable chamber directly to a vacuum pump. In the present study, a comparison was made between a normal room without a portable chamber and another with a portable chamber. Six different strategies were applied to remove pollutants. The results showed that strategy 6 was more effective than other strategies (2, 3, 4, and 5) by percentages of 61.6%, 70.4%, 52.4%, and 33.0%, respectively.

“…However, the parameters measured in this study are only the outdoor emissions, and there are no measurements of the hospital's indoor air quality. Meanwhile, indoor environment quality is significant to evaluate green building certifications [17], in order to ensure the sustainability of a hospital. Therefore, a further study is needed to identify the indoor air quality.…”

Sustainability is one of the most important issues in the recent year for almost all country in the world. Good environmental monitoring and policy is needed to meet the sustainability. Hospital is one of the most important public facilities, especially during pandemic situation. Therefore, environmental monitoring for this building is necessary. The purpose of this research is to know the monitoring result of a hospital in Yogyakarta by using government regulation. Effluent of wastewater (BOD, COD, TSS, TDS, Coliform, etc.), ambient and emission air quality (SO2, NO2, CO, particulate, etc.) and solid waste management are investigated periodically by using standard regulation. The findings of the present study showed that almost all tested parameters are under the permitted level of the local regulation (Yogyakarta Province). Best practice of the hospital should be considered as a good contribution in term of sustainability.

“…However, the increase in temperature may affect the relative humidity of the air that is very low ISTEcS 2019 to cause discomfort. The fan installation and increased air filter to controlled humidity with the option to the indoor air quality improvement for providing appropriate good environment was another way to control indoor air quality [22]…”

Indoor Air Quality (IAQ) is one of the critical issues in sustainable development related to human health as the primary goal. Sustainable development should address potential human exposure to pollutants and health impacts. The laboratory, as educational support in the university, has specific contaminants, but studies on IAQ and thermal comfort in the laboratory have not been studied. IAQ and thermal comfort in a laboratory are essential as they can affect the work and health of the researchers and staffs. The purpose of this study is to analyze indoor air quality in an integrated laboratory of UIN Sunan Ampel Surabaya. This research is a cross-sectional study. Data analysis was done by a quantitative descriptive method. The air quality parameters in the laboratory were temperature, relative humidity, and carbon dioxide (CO2) concentration. All settings compared to the air quality standard. The analysis on carbon dioxide (CO2) concentration, relative humidity (%RH), temperature (∘C) has shown that the indoor air does not exceed the standard according to ASHRAE standard and Health Ministry Regulation with the maximum concentration was 444,3 ppm. The fan installation and increased air filter to controlled humidity are the option to improve the indoor air quality.
