Understanding the substantial negative impact that deficient building performance, poor indoor air quality, excessive interior and substructure moisture and HVAC system inadequacies have on the Lowcountry's residents and business owners; and realizing a lack of engineering professionals concentrating in this specialized area, Louis Schweers founded GLS Engineering in 2003.  A Licensed Professional Engineer with over 20 years of residential and commercial experience, Louis has concentrated almost exclusively on HVAC, moisture and indoor air quality issues.  His unique combination of education and "real-world" experience qualifies him as one of the foremost forensic engineers in South Carolina.  Recognized as a leading authority in the field, Louis is often asked to provide expert testimony in legal cases involving mold, moisture, building performance and indoor air quality issues.
