to implement an Indoor Air Quality (IAQ) Management Plan during
construction that reduces indoor air quality problems and reduces
health issues with construction workers and building
Implement an IAQ Management Plan during construction and
pre-occupancy as follows:
Meet or exceed the recommended Control Measures of the Sheet Metal
and Air Conditioning Contractors National Association (SMACNA) IAQ
Guidelines for Occupied Buildings under Construction.
Protect stored or installed absorptive materials from
Install filtration media with a Minimum Efficiency Reporting Value
(MERV) of 8 at all return air grilles on permanently installed air
handlers used during construction.
Replace all filtration media immediately prior to occupancy
- Include construction IAQ requirements in all relevant
specifications, including front-end project requirements, to the
specific MEP divisions.
- Include construction IAQ quality control related items in the
projects weekly progress meetings with the team.
- Specify the sequence of installation of finishing materials
according to the Reference Specifications for Energy and Resource
Efficiency, section 1350.
- Assign a responsible party for documenting how the project is
following the five SMACNA approaches early in construction. Photos
from three different occasions in the project are required, and it
is not possible to take all of them at the end of the project.
- Create the IAQ Plan before construction begins. This ensures
all SMACNA approaches are addressed.
- The required control measures are generally standard
construction practices in such facilities as hospitals or
laboratories where indoor environmental air quality is
- 58% of all California LEED Certified projects achieved this
credit for LEED v2.1.
