LEED Project Construction Air Quality Management

Constructin IAQ Monitoring Particle Counter Testing ServicesManaging Indoor Air Quality (IAQ) during construction and before occupancy systematically is becoming more and more common as contractors gain more experience with LEED.
IAQ monitoring during new construction and renovation projects has considerable benefits, not to mention the reduction of risk for the Owner, Developer, and Construction Management firms.  
CES has provided LEED Construction Air Quality Management compliance on the following projects:
  1. Nemours Children's Hospital - 13535 Nemours Parkway Orlando, FL 32827 - LEED BD+C: New Construction v2 - LEED 2.2 - LEED GOLD 2013
  2. Verizon Lake Mary - 899 Heathrow Park Lane Lake Mary, FL 32746 - LEED ID+C: Commercial Interiors v3 - LEED 2009 - v3 - LEED 2009
  3. Nicolson Center For Surgical Advancement - 404 Celebration Pl, Celebration, FL 34747 United States - LEED Design Certification

The intent of Construction IAQ Monitoring and LEED EQc3.2 is to:
  1. Minimize exposure of construction workers to air pollutants;
  2. Prevent air pollutants from collecting in building systems and on building materials; and
  3. Prevent air pollutants caused by construction from migrating into occupied spaces.

Air pollutants are defined as:

  • Particulates;
  • Volatile organic compounds;
  • Formaldehyde;
  • Combustion emissions;
  • Airborne bacteria and micro-organisms; and
  • Airborne inorganic compounds, such as ozone (from electrical motors), metal fumes (from smoldering and welding), and ammonia and chlorine (from cleaning products).

Requirements of LEED EQc3.2 

Develop and implement an Indoor Air Quality (IAQ) Management Plan for the pre-occupancy phase as follows:

Conduct baseline IAQ testing, after construction ends and prior to occupancy, using testing protocols consistent with the United States Environmental Protection Agency Compendium of Methods for the Determination of Air Pollutants in Indoor Air and as additionally detailed in the Reference Guide.Demonstrate that the contaminant maximum concentrations listed below are not exceeded.

For each sampling point where the maximum concentration limits are exceeded conduct additional flushout with outside air and retest the specific parameter(s) exceeded to indicate the requirements are achieved.  Repeat procedure until all requirements have been met.  When retesting non-complying building areas, take samples from the same locations as in the first test.

The air sample testing shall be conducted as follows:
  1. All measurements shall be conducted prior to occupancy, but during normal occupied hours, and with the building ventilation system starting at the normal daily start time and operated at the minimum outside air flow rate for the occupied mode throughout the duration of the air testing.
  2. The building shall have all interior finishes installed, including but not limited to millwork, doors, paint, carpet and acoustic tiles. Non-fixed furnishings such as workstations and partitions are encouraged, but not required, to be in place for the testing.
  3. The number of sampling locations will vary depending upon the size of the building and number of ventilation systems. For each portion of the building served by a separate ventilation system, the number of sampling points shall not be less than one per 25,000 sq.ft., or for each contiguous floor area, whichever is larger, and include areas with the least ventilation and greatest presumed source strength.
  4. Air samples shall be collected between 3 feet and 6 feet from the floor to represent the breathing zone of occupants, and over a minimum 4-hour period.
