Does your building need Indoor Air Quality compliance requirements for LEED Certification?

In order to comply with IEQ Credit 3.1: Construction Indoor Air Quality Management Plan—During Construction of LEED 2009 Rating System, an Indoor Air Quality management plan must be developed and implemented for the construction and pre-occupancy phases of the building.

This plan consists of:

  •  Applying IAQ control measures for occupied buildings under construction.
  •  Protecting stored on-site and installed absorptive materials from moisture damage.
  •  Prohibiting operation of permanently installed air handling equipment during construction.
  •  When applicable, using filtration media with a minimum efficiency reporting value (MERV) of 8.

We know your project requires this compliance and your priority will be ours.  

Likewise, in order to earn the IEQ Credit 3.2: Construction Indoor Air Quality Management Plan—Before Occupancy of LEED 2009 Rating System, an IAQ management plan must be developed and implemented after all finishes have been installed and the areas have been completely cleaned, before the building is occupied.

An option for compliance with this credit is to conduct air testing which consists of:

  •  Conducting a baseline Indoor Air Quality test after construction ends and prior to occupancy under ventilation conditions typical for occupancy.
  •  Testing mandatory contaminants such as: formaldehyde, particulates (PM10), total volatile organic compounds (TVOC's), carbon monoxide and 4-Phenylcyclohexene.
  •  Testing that demonstrates specific contaminants' maximum concentration levels are not exceeded.

At Zimmetry we help you achieve seamless compliance with these requirements by:

  •  Working with a LEED Accredited Professional Consultant.
  •  Using laboratories accredited by the American Industrial Hygienist Association.
  •  Referencing, when applicable, the ASHRAE 52.2-2007 standard.
  •  Referencing the Sheet Metal and Air Conditioning National Contractors Association (SMACNA) IAQ Guidelines For Occupied Buildings Under Construction.
  •  Using protocols consistent with the EPA Compendium of Methods for the Determination of Air Pollutants in Indoor Air or International Standard Organization.
