mitigate potential health risks.

Humidity sensors measure the moisture content in the air. They help maintain optimal humidity levels,

preventing issues like mold growth and ensuring occupant comfort.

Temperature sensors monitor the ambient temperature in different areas of the complex. They assist

in regulating heating and cooling systems, ensuring a comfortable indoor environment for occupants.

By using sensors to measure pollutants levels, humidity, and temperature, building managers can

make informed decisions regarding ventilation, air filtration, and energy management. This data allows

for proactive measures to improve indoor air quality, enhance occupant comfort, and optimize energy

efficiency. (P. Wei 2018).

4.3. TIMELY INTERVENTION BASED ON MONITORING RESULTS

Timely intervention based on monitoring results is crucial in maintaining a healthy and comfortable

environment in a mixed-use complex. When the monitoring system detects any deviations or issues,

prompt action can be taken to address them. Here’s how it works:

1. Pollutant Levels: If the sensors detect high levels of pollutants, such as VOCs or CO, building

managers can investigate the source of the problem and take immediate steps to mitigate it. This may

involve adjusting ventilation systems, identifying and removing pollutant sources, or implementing air

purification measures.

2. Humidity Control: When humidity sensors indicate excessive moisture levels, timely intervention

can prevent mold growth and maintain a comfortable environment. This might involve adjusting

ventilation, using dehumidifiers, or identifying and fixing any leaks or moisture-related issues.

3. Temperature Regulation: Temperature sensors help ensure that the complex remains at a

comfortable level for occupants. If sensors detect temperature deviations, adjustments can be made to

the heating or cooling systems to maintain the desired temperature range.

By acting promptly based on monitoring results, building managers can address potential air quality

issues, maintain optimal humidity levels, regulate temperature, and ultimately create a healthier and

more comfortable environment for everyone in the complex.
