Over years of professional practice, teaching and scientific research Dr. Michael Berry is a true pioneer in identifying the foundational principles of what cleaning really means. His book, Protecting the Built Environment: Cleaning for Health, was ahead its time. Unfortunately those in the industry that should have taken hold of Berry’s principles have continued business-as-usual.
Most cleaners and janitorial operations are still cleaning the way they did 80 years ago. They are driven by equipment manufacturers and chemical companies that dictate the direction of the industry. There is no evidence based research. There is no common language or standards. The only focus of cleaning is appearance based with no thought about contaminants and indoor environmental problems.
Below is a link to the complete transcript of the presentation that was delivered by Michael Berry, PhD, at the 2006 Simon Institute Symposium. In this presentation, Berry discusses the value of cleaning science; the effect of sick and mismanaged buildings; remediating the Frank Porter Graham building with a deep cleaning protocol and the findings from his 2006 publicly funded study of traditional housekeeping vs. the (OS1) cleaning process. That study evaluated traditional housekeeping methods vs. a high performance cleaning program over the span of three months at The University of North Carolina. It is also important to note that Berry also discusses key components of a high performance cleaning program in this presentation.
