Project Details

Project Name: Provided an IAQ Assessment
Country: USA
Description: Provided an IAQ assessment of one floor building comprised of office areas, drafting areas, and support systems. The assessment included air constituent and air contaminant monitoring. Also, an inspections of the HVAC system was conducted to identify any buildup from dust, mold, or mildew and to identify possible malfunctions in the systems. No air contaminants were outside recommended EPA/OSHA/NIOSH limits. Carbon dioxide levels were up to four times outside levels. The maximum level measured was 1600 ppm. Recommendations included a maintenance schedule for HVAC returns and exhausts, opening dampers on the HVAC system to increase the fresh air intake, balancing air flow to increase air movement in the copier room, and reporting of testing results to the building occupants. A follow-up assessment was completed after maintenance procedures had been carried out on the HVAC system. The carbon dioxide levels had been cut by more than half in all areas tested. Further adjustments were made to balance the fresh air intake to temperature and humidity.
