 *Bau-Biologie®, a philosophy that began in Germany, is a word used to describe a movement promoting the use of healthy building principles as a means to improve living and work spaces and the health of people who occupy them. Bau-Biologie® literally means, "Building Biology™." Both terms are now used interchangeably and both have exactly the same definition - "how buildings impact life and the living environment." 

**Jon also holds the U.S. EPA Lead-Safe RRP Certificate. EPA requires that firms performing renovation, repair, and painting projects that disturb lead-based paint in pre-1978 homes, child care facilities and schools be certified by EPA and that they use certified renovators who are trained by EPA-approved training providers to follow lead-safe work practices.


We look forward to hearing from you!
