Instructor
Wei Sun
Wei Sun served as IEST Society President in 2016-2017, and Technical Vice President (Contamination Control) in 2013-2016, he has been the chair of WG-CC012 that is responsible for the new edition of RP-CC012.3 (Considerations in Cleanroom Design), and now leading the group working on the new RP-CC012.4 Edition.
Sun also has served as the Chair of ASHRAE Technical Committee TC9.11 (Clean Spaces) from 2007 to 2010, a voting member of ASHRAE TC9.10 (Laboratory Systems) and TC9.6 (Healthcare Facilities). He is an ASHRAE Fellow and an ASHRAE Distinguished Lecturer since 2008. In addition to his design expertise for large cleanroom, lab, and healthcare projects; he has been serving as a Principal Investigator for many governmental research projects, over a dozen of technical articles have been published. Recently he published a new technical book (426 pages) called “ASHRAE Design Guide for Cleanrooms”.
Furthermore, Sun is an ISO 14644 standards’ USA delegate for Working Group 4 (cleanroom design and construction) and Working Group 16 (energy conservation in cleanrooms). Sun recently has been serving as the chairperson of NEBB’s Cleanroom Performance Testing (CPT) Standard Committee and developing a new cleanroom testing standard for NEBB.
He has been invited to provide numerous technical speeches and training courses for private US industries, governmental agencies, national, and international conferences.
