This Guide is based on several decades of authors research and practical experience in the areas of process optimization, ventilation and energy conservation in welding shops of auto manufacturing and maintenance facilities. The Guide will describe principles of Weld Fume Control, advanced ventilation systems for facilities with welding and allied processes and with energy conservation opportunities that result from the process related measures to reduce emission of fumes and gases and the building envelope improvements. The objectives of the Guide are to improve the health and safety in the industrial environment and offer strategies for energy conservation. The Guide is designed for engineers, production operators and energy managers.

Dr. Alexander Zhivov is a senior research engineer at the Engineer Research and Development Center Construction Engineering Research Laboratory. He holds a Ph.D. degree in mechanical engineering from the Central Research and Experimental Design Institute for Industrial Buildings, Moscow and the Research Institute for Labor Protection, Leningrad, and an MBA degree from University of Illinois at Urbana-Champaign.
Throughout his carrier he worked as a senior engineer in Industrial Ventilation Design Institute in Leningrad, conducted research in the area of air and contaminant distribution in industrial spaces, studied and designed innovative industrial ventilation systems at the Central Research and Experimental Design Institute in Moscow and at the Research Institute for Labor Protection in Leningrad, he was a co-founder and between 1989-1991 was a general manager of the Soviet-Swedish joint venture SOVPLYM that develops, designs manufactures and installs industrial ventilation systems focusing on welding and auto-repair/manufacturing shops.
Between 1991 and 2003 he was a visiting, adjunct and assistant professor at the Bioenvironmental Engineering Research Laboratory at the University of Illinois in Urbana-Champaign, Illinois. During 1996 and 2003 Dr. Zhivov served as a chairman of the International Task Force Ventilation for Automotive Industry and significantly contributed to the Industrial Ventilation Design Guidebook developed by a group of international experts and published by Academic Press in 2001.
Since 2003 Dr. Zhivov joined the US Army Construction Engineering Research Laboratory in Champaign, Illinois, where he is responsible for Army-wide facilities energy strategic planning leading to implementation of new HVAC systems, distributed generation technologies, renewable energy, heating plant modernizations, building commissioning processes, and modeling and analysis tools for installation operations. He develops the framework and concepts of a secure, reliable, and efficient Army installation energy strategy and supporting implementation programs.
