Theoretical models for both indoor pollutant concentration and indoor air humidity have been studied together with a general ventilation model for the prediction of indoor pollutant concentrations. These are discussed in detail with reference to carbon dioxide (CO₂) levels using the concentration of 1,000 ppm guideline from ASHRAE Standard 62 as a design criterion. At the same time, a moisture balance linear differential equation was adopted to predict the indoor humidity from a ventilation airflow rate adjusted to meet the requirement of given CO ₂ concentrations. The studies also took into consider ation the effective temperature required for indoor thermal comfort. Finally, weather data from Taipei city in Taiwan was applied to the design calcula tions.
