Baseline Indoor Air Quality (IAQ) Investigations
Proactive Baseline Indoor Air Quality (IAQ) Investigations have proven to reduce building management costs by identifying improperly operating building systems before indoor air quality problems result in occupant health complaints and costly remediation. We at EE&G offer Baseline Indoor Air Quality (IAQ) Investigations to the public and private sector.
A typical EE&G baseline annual IAQ survey may include:
- Complete home inspection of Heating, Ventilation and Air Conditioning (HVAC) systems
- Walk through inspection for potential sources and pathways of poor air quality
- Review of current in-house HVAC maintenance programs
- Collection of thermal comfort parameters (temperature and relative humidity)
- Evaluation of fresh air entering the building
- Screening for chemical agents (e.g. Formaldehyde, TVOCs) as appropriate
- Monitoring for other common agents associated with IAQ complaints including airborne mold and bacteria, particulates, carbon dioxide, carbon monoxide, temperature, relative humidity and dew point.
Establishing an Adequate (IAQ) Baseline
Update Building Records Important to an IAQ Management Program. We at EE&G Develop an organized system to obtain and maintain the following building records:
- “As built” blueprints, including modifications to reflect current conditions.
- Up-to-date drawings of all tenants’ build outs and interior renovations.
- Records of major space use change not reflected in the original design.
- Drawings of pressure relationships.
- Operating and Maintenance Plans and Schedules.
- Historical Occupant IAQ complaint logs (if available).
Inventory of products and materials that are sources of pollutants, with MSDS sheets and related information.
I-BEAM provides convenient forms for tracking progress in developing and maintaining some building records. Documents that may be useful in organizing these records include:
- Construction documents
- Commissioning reports
- Operating manuals
- HVAC maintenance records
- Remodeling and Renovation records
- Records of equipment modifications/replacement
- Records of complaints
- Conduct a Baseline Building Audit to Determine IAQ Status in the Building
When first starting an IAQ program, conduct a whole building walk-through to record the status of all IAQ parameters identified in I-BEAM. Take simple measurements of pressure relationships and air flow patterns as may be appropriate, and record where more detailed measurements may be needed at a later date to complete the basic profile.
