Schedule the application of paints and coatings so that off-gassing does not contaminate other absorptive materials. This is required if projects are attempting IEQc3.1: Construction Indoor Air Quality Plan—During Construction. For example, do not store or install acoustic ceiling tile before flooring and wall paints are put down, because ceiling tiles will absorb the off-gassing of paint and contaminate the air over a longer time period.
Alternatives to installing MERV 8 filters include not using the building HVAC units, bringing in a stand-alone temporary system, or using natural ventilation.
Replace construction filters with MERV 13 filters if the project is also attempting to earn credit for IEQc5: Indoor Environmental Pollutant Source Control.
All five SMACNA control measures have to be documented in a photo log. It is easy to take pictures of covered ducts, but don’t forget to also take photos of more process-oriented strategies such as housekeeping and pathway interruption. The pictures should clearly show all the control measures adopted during construction.
Take photos throughout the construction process to demonstrate that your IAQ plan has been followed. There is no specific number of photos required, but they must be taken at two or more different stages of the project.
