On September 25, industry consultant Jerry Yudelson presented his just completed study of leading edge European green building technologies during the latest MCAA green webinar. Yudelson's study was funded by the Mechanical Contracting Education & Research Foundation (MCERF). A national audience of MCAA contractor members heard Yudelson describe the latest European engineering designs and practices that have produced highly efficient and healthy buildings. Industry culture and climate differences may determine how adaptable these technologies are to North American building projects.
