Indoor air quality is a critical component of the LEED certification process (2017). To meet LEED requirements, LCS Laboratory has developed comprehensive sampling procedures that enable consultants and building managers to assess air quality effectively. Our customizable sampling kits include all necessary equipment, media, and laboratory analysis in one convenient package. Below is an overview of the tests we offer:
