Anthony Lenard is a premier Indoor Environmental Professional and building science specialist known across the industry for his forensic approach to structural health, indoor air quality (IAQ), and complex mechanical performance. With over 28 years of experience spanning building physics, advanced HVAC design, and environmental testing, Anthony bridges the gap between how a building is constructed and how it actually performs in the real world.  

‍

He specializes in pinpointing the root causes of building envelope failures, pressure imbalances, and persistent environmental health hazards. Whether executing surgical mold inspections, evaluating duct airflow dynamics according to National Comfort Institute (NCI) standards, or designing specialized remediation protocols for health-compromised and CIRS-sensitized occupants, Anthony’s work consistently elevates building efficiency, durability, and occupant well-being.
