M.S., Applied Solar Energy
Trinity University, TX, 1983
Over 20 years at FSEC with extensive experience lecturing, training, and developing training materials and programs, on the topics of energy use, air flows, duct leakage, diagnostic methods, and indoor air quality.
Principal investigator for 26 research projects with budgets totaling approximately $3.4 million. Major research field projects include duct leakage in 160 homes, radon pressure/airtightness/infiltration testing in 70 homes, uncontrolled air flow testing in 70 commercial buildings, and uncontrolled air flow and HVAC performance testing in 20 commercial buildings. Instrumental in designing and getting constructed the Building Science Research and Training Facility at FSEC.
Performed tracer gas, blower door, duct leakage, and pressure mapping testing in more than 250 homes and more than 90 commercial buildings to as large as 450,000 square feet. Developed innovative diagnostic test methods and protocols for characterization of airflows, building air barriers, and building zone pressure mapping. Carried out pioneering field and lab research identifying the nature, extent, and consequences of duct leakage and other forms of uncontrolled air flow in residences and commercial buildings.
Developed and offered 38 intensive 6-day duct diagnosis and repair courses to HVAC contractors, utility personnel, low-income weatherization programs, and building science trainers. Developed a 450-page duct repair training manual and 15-minute training video titled The Pressure is On; Duct Repair for Safer and More Affordable Homes. Was Principal Investigator for Energy Smart Schools Designing the Failure Proof Building 10-day training series. As a consultant with Building Diagnostic Solutions, has tested a wide range of residential and commercial buildings for uncontrolled airflows, radon intrusion, and moisture problems for more than forty clients. As a voting member of the Florida Building Commission Mechanical Technical Advisory Committee, ASHRAE TC 6.3, and SPC 152 Duct Tightness Standard, and chairman of the ASHRAE Journal/Insights Committee, has actively integrated findings from his research into applicable codes and standards.
