Indoor air quality in two different commercial buildings: Part 1: ventilation, temperature, humidity of air and gas concentrations - Communication au Congrès Healthy Bulidings 2003

Résumé et principaux résultats

The main objective of this study was to investigate the Indoor Air Quality (IAQ) in office buildings and to understand better how HVAC (Heating, Ventilation and Air-conditioning) systems work and what their effects are on IAQ over a sustained period. Two French commercial buildings were chosen, located in urban areas of Lyon and Paris, and for one day a month, over the course of 1 year, a number of IAQ related variables were recorded both inside, including the HVAC system, and outside the buildings. Physical parameters of temperature, relative humidity, air flow rate, gas concentration (CO, CO2, NOx, HCHO), air bio-contaminants (fungi, bacteria), dust concentrations and air filter efficiencies were evaluated. The results presented in this article show the relationships between HVAC air flow rates and occupant comfort, and illustrate the variation in IAQ for two French commercial buildings. Other data are presented and discussed in Part 2 of the article.
