- HVAC protection
- Source control. Keep sources of contaminants out of the building and have a plan to eliminate any that are
introduced.
3.Pathway interruption. Prevent circulation of contaminated air when cutting concrete or wood, sanding drywall,
installing VOC-emitting materials, or performing other activities that affect IAQ in other work spaces - Housekeeping. Maintaining a clean job site results in fewer IAQ contaminants to manage
- Scheduling. Sequence construction activities to reduce air quality problems in new construction projects. For major
renovations, coordinate construction activities to minimize or eliminate disruption of operations in occupied areas.

Sound Reinforcement (1) and Masking Systems (1)
Sound Reinforcement
For all large conference rooms and auditoriums seating more than 50 persons, evaluate whether sound
reinforcement and AV playback capabilities are needed.
Masking Systems
For projects that use masking systems, the design levels must not exceed 48 dBA. Ensure that loudspeaker coverage
provides uniformity of +/–2 dBA and that speech spectra are effectively masked.

Sound Reinforcement
For all large conference rooms and auditoriums seating more than A persons, evaluate whether sound reinforcement and AV playback capabilities are needed.
If needed, the sound reinforcement systems must meet the following criteria:
·1· Achieve a speech transmission index (STI) of at least B or common intelligibility scale (CIS) rating of at
least C at representative points within the area of coverage to provide acceptable intelligibility.
·2· Have a minimum sound level of D dBA.
·3· Maintain sound-level coverage within +/–E dB at the F Hz octave band throughout the space.
Masking Systems
For projects that use masking systems, the design levels must not exceed G dBA. Ensure that loudspeaker coverage provides uniformity of +/–H dBA and that speech spectra are effectively masked.
