Indoor Environmental Quality in a Public Library in Sao Carlos, SP, Brazil

Abstract

The temperature, relative humidity, noise, carbon dioxide, and particulate matter (PM10) in a pub-lic library in São Carlos, SP, Brazil, were monitored between May and September 2013. The build-ing is naturally ventilated through tilted windows and doors. The PM10 concentrations in August and September were the highest when rainfall was at levels near zero. Over the entire study pe-riod, the temperature and relative humidity values were acceptable, but most users consider the library to be hot on hot days and cold on cold days. The CO2 and noise levels were below the rec-ommended standard, but the users and employees of the library frequently complain about the noise levels.
