Three mentors shaped my professional life. The first one was in Warsaw, Poland, Prof. Bohdan Lewicki, whose books on concrete panels were translated in many languages. One day, after his class, he told me： ＂We need to evaluate hygrothermal performance of an experimental building with no-fine concrete,--if you would like to do it, I will provide you with aU the money needed. From this day on, I have been learning Building Physics. My second mentor was Prof. Lars Eric Nevander in Lund, Sweden, one of the three Swedish professors who in 1972 introduced limit states method into the field of durability assessment, exactly 40 years before the first ISO standard did so. Lars Eric taught me that progress in construction depends on how strong is the continuum between industrial and academic domains in Building Physics.展开更多
