The American Indoor Air Quality Council has unveiled a search engine on its Web site,www.iaqcouncil.org, allowing full access to its database of registered recertification activities. The engine allows certificants to search for recertification credit (RC) opportunities by a variety of categories, including course location, course date, course name, provider name or course RC value. A zip code search returns all qualifying courses within a 100-mile radius of the zip code entered.
