A Study on CO₂ Concentration Control to improve IAQ(Indoor Air Quality) in Office Building

This paper aims at simple methodolgy that can improve the CO2 concentration control based on HVAC(Heating Ventilation and Air Conditioning) engineer experiences. The airtightness in present intelligent buildings are usually dependent on HVAC system. But most HVAC system that are controlled voluntary by engineer s experience cause sick building syndrom , which is a new disease. This paper first analyzes CO2 concentration pattern in an intelligent building. We then formulates a simple methodology that is characterized by linear functions. An automatic control mechanism is developed using the functions and a software tool is implemented. According to these results, the methodology advanced in this paper is better than the HVAC control using HVAC engineer s experiences.
