Investigating the Recommended Interventions

4.3 INVESTIGATING THE RECOMMENDED INTERVENTIONS

Based on the EMS script coding integrated in the model, the demand control ventilation of the room will run first by assessing the CO2 concentration indoors against the outdoor concentrations of PM2.5, meaning if the CO2 concentrations indoors are high whilst the external concentrations of PM2.5 are low (both based on the set criteria), then the ventilation will run accordingly – if the CO2 concentrations indoors are high whilst the external concentrations of PM2.5 are high as well, meaning there is high outdoor pollution, ventilation will not be operated. Likewise, if CO2 concentrations fall below the set criteria, ventilation will not operate.
