               Last month we had a wonderful dinner presentation from Lew Harriman, ASHRAE Distinguished Lecturer on how HVAC Systems Help or Hurt a Building.  Pictured below is Lew Harriman (Left) and our own Distinguished Lecturer, Bill Lotz (Right).  Thank you to everyone who attended and another thank you to those who emailed me the DL evaluation forms.  Lew scored very high with the chapter and we look forward to having him back again.                Last month we had a wonderful dinner presentation from Lew Harriman, ASHRAE Distinguished Lecturer on how HVAC Systems Help or Hurt a Building.  Pictured below is Lew Harriman (Left) and our own Distinguished Lecturer, Bill Lotz (Right).  Thank you to everyone who attended and another thank you to those who emailed me the DL evaluation forms.  Lew scored very high with the chapter and we look forward to having him back again.

"All countries want to achieve high standards of energy efficiency," author Lew Harriman said. , but also because of requests from government agencies in developing countries that are working to establish robust building codes to guide energy use and indoor environmental quality," Harriman said. The instructor is Lew Harriman, author of the design guide and director of research and consulting at Mason-Grant in Portsmouth, N.H. "This collection provides extensive technical background along with specific suggestions for avoiding mold- and moisture-related problems," Lew Harriman, a member of ASHRAE's technical committee on moisture management in buildings, said. The papers and articles address mold fundamentals, moisture movement in building assemblies, dehumidification and HVAC systems, and also discussions of typical problems and solutions for both commercial and residential buildings. "Problems associated with mold and moisture seldom fall neatly into any single professional responsibility," according to Harriman. "Biology, medicine, engineering, architecture, construction and building operation all contribute to understanding and managing moisture in buildings. When difficulties occur, they usually expose gaps between these disciplines and often expose shortcomings of our overall understanding of the behavior of moisture and its consequences." The collection can help the professional community as well as the general public understand the technical issues surrounding mold and mildew, according to Harriman.
