Hi guys I am assigned to do the indoor air quality measurement in 5 buildings which are 2 academic buildings, one residence, a library and a gym. I have to establish a methodology to measure CO2, temperature, humidity, air movement as well as particulates. I have 2 months time to measure and analyse data to represent buildings with poor indoor air quality. My problem is establishing the time and duration of measurement for each parameter in these buildings. Moreover I do not have any idea in which areas it would be better to do the measurements (for example one classroom in first and top floor?). I got confused because I think 2 month is not enough for measuring all these parameters in 4 buildings.Do you have any idea?I appreciate your help!
