John Clark, P.E. has tackled a variety of subjects as an author for ES over the years. Topics just in the last couple of years have ranged from commercial kitchen ventilation design to seasonal ventilation issues regarding vestibules, on to the role of the special inspector for smoke control systems. His approach, however, has always remained grounded in fundamental knowledge and a keen eye for the most efficient way to get from Point A to Point B. We're happy to share this month's Q&A with John, who brings more than 40 years' experience and a friendly countenance to his work at Hammel Green & Abrahamson (www.hga.com) in Minneapolis, as well as to his regular contributions at ASHRAE gatherings.
