NC DENR Building

The Leadership in Energy and Environmental Design (LEED®) Green Building Rating System represents the U.S. Green Building Council’s effort to provide a national standard for what constitutes a green building. There are specific requirements which must be met to achieve voluntary credits. Points accumulate to a final score that relates to one of four possible levels of certification. Credit 3.2 in the Indoor Environmental Quality (IEQ) section of the program is entitled Construction Indoor Air Quality Management Plan – Before Occupancy and is designed to reduce indoor air quality problems resulting from the construction/renovation process, to sustain long-term worker and occupant comfort and wellbeing.

Froehling & Robertson, Inc.’s industrial hygienists supplied Indoor Environmental Quality (IEQ) testing for the North Carolina Department of Environment and Natural Resources (DENR) headquarters, located at Green Square, in Raleigh. Our successful completion of these services provided one of the keys to the attainment of the LEED Gold Certification on this flagship office.

After an initial pre-screening designed to observe and note all instances and factors that may negatively impact results, F&R’s industrial hygienists performed sampling at 15 locations throughout the building. The indoor air quality testing services included analysis for: formaldehyde, total volatile organic compounds (TVOCs), particulate (PM-10), and Carbon Monoxide (CO).
