Building owners and tenants are concerned about the cost-effective performance of the environmental systems within their respective buildings. This "green" goal can be best accomplished by having a building’s environmental system properly tested, balanced and/or commissioned by a NEBB Certified Professional or Technician. NEBB’s function is to establish, promote and maintain high quality standards through certification of Firms, Professionals and Technicians.
