Thomas B. Axley, Jr.
Senior Consultant / P.E. / Nashville
Mr. Axley has over 30 years of a wide variety of engineering experience with highly specialized experience in commercial and industrial HVAC. His background provides him with experience in investigations and apparent causal analysis in the areas of industrial and nuclear HVAC with specific investigation and troubleshooting experience in industrial exhaust hood performance, industrial ventilation system failures, component failures, and HVAC equipment and system performance in environments such as office spaces, laboratories, hazardous location areas and power generation facilities (nuclear, coal fired, natural gas and hydro-electric).
Mr. Axley has overseen or performed detailed designs for nearly 100 projects ranging including single zone DX systems, chilled water and associated pumping, swimming pool de-humidification, low pressure steam systems, hot water systems, dedicated outdoor air systems, heating boilers, class 10,000 clean rooms, laboratory facilities, and radiochemical/explosives facilities and primary/secondary/ tertiary confinement systems in a variety of industrial ad laboratory facilities.
In addition, Mr. Axley co-authored a white paper discussing filtration strategies for primary containment emergency ventilation exhaust streams on behalf of the General Electric Boiling Water Reactors Owners Group after the Fukushima Daichi earthquake. He oversaw the design and specification of the primary, secondary and tertiary confinement exhaust and make-up air systems at a large uranium processing facility in Tennessee.
Mr. Axley has performed energy surveys for the U.S. Department of Defense and due diligence surveys for commercial lenders. He has designed or investigated failures in building sanitary, drains, sewage lift stations/grinder pumps, pneumatic sewage ejectors, potable water and domestic hot water systems. He has also investigated failures in asbestos cement piping in underground cooling tower/service water applications.
This broad as well as detailed experience in addition to involvement in the ASME Nuclear Air and Gas Treatment Code (AG-1 Committee) and ASRAE Technical Committees 9.2, 5.8, 5.4 and 5.2 provides Mr. Axley with an in-depth knowledge of nationally recognized codes and standards applicable to HVAC and Industrial Ventilation / Air Conditioning Systems including multiple sections of the ASME Boiler and Pressure Vessel Code, ASME B 31.series piping codes, ASHRAE standards and NFPA codes. In addition, Mr. Axley’s experience includes conformance with OSHA and other pertinent safety standards related to industrial HVAC and ventilation.
Mr. Axley is a contributing author to the ASHRAE Applications Handbook (Nuclear Facilities and Power Plants) and is a voting member of the ASME Committee of Nuclear Air and Gas Treatment (CONAGT) AG-1 Standards Committee in addition to two subcommittees and is currently leading an effort for major revision to AG-1 updating quality assurance and baseline codes and standards. Mr. Axley has taught Statics and Thermal Sciences as an adjunct professor in various two-year degree programs at Chattanooga State Community College.
