University of Louisville
OP-5: Indoor Air Quality

The University of Louisville has several fixed Carbon Dioxide (CO2) continuous monitoring systems in the return air systems of buildings for purposes of energy conservation/Indoor Air Quality and which meet the ASHRAE 62.1 “Ventilation for Acceptable Indoor Air Quality” requirements. This program and systems are monitored by Physical Plant’s energy management. The new LEED Gold Student Recreation Center and the new LEED Silver Lynn Soccer Stadium are fully compliant with the ASHRAE 62.1 requirements, as well will be any other new buildings constructed. Other University buildings, which also have CO2 monitoring systems in the return air systems, include the Natatorium and several auditoriums in buildings, such as Strickler Hall, Davidson Hall, Humanities and Student Activities Center. If the CO2 levels in these return air systems reaches above 1100 ppm of CO2, the outside air fully opens to bring in more fresh air. The full list of buildings which have these fixed CO2 continuous monitoring systems includes: Baptist, Planetarium, Business, Education, EKS, Papa John's Cardinal Stadium, Houchens, Duthie, Law, MITC, Natatorium, Playhouse, SAC, Schneider, Strickler, Yum Center, Davidson, Humanities, Music, Natural Science, Lynn Soccer Stadium, Student Rec Center, HSC instructional building, Center for Translational Research, Dental School, Burhans Hall and Center for Predictive Medicine. Other measures which the University has taken towards improving Indoor Air Quality include Department of Environmental Health and Safety (DEHS) efforts in conducting investigations and tracking indoor air quality issues/projects (on Sharepoint); development of procedures for addressing indoor air quality complaints and measures which building and residential housing occupants can take to improve indoor air quality (IAQ). There is an IAQ log for occupants to track occurrences of odors or other IAQ issues. Finally, there is a questionnaire (occupant survey) for occupants/complainants to complete to request an investigation and/or monitoring by DEHS. This questionnaire provides detailed information for DEHS to conduct the IAQ investigation and most often assists with determining the root cause of the IAQ problem. The link to the procedures, IAQ log, and IAQ request/survey and other Indoor Air Quality information are available on the DEHS website at http://louisville.edu/dehs/ohs/iaq
