Building Investigation

Building investigation protocol follows a logical progression through three phases. All three phases may not be necessary for problem resolution. 

Phase I: Qualitative Diagnostics - consultation and problem definition. This phase involves

  • Occupant interviews
  • Building plans review
  • Inspection of affected building areas
Building Investigation
  • Inspection of heating, ventilating, and air conditioning (HVAC) systems
  • Spot measurement of temperature, relative humidity, and carbon dioxide (CO2)
  • Report of phase 1 findings and recommendations - all reports will document findings, report known and potential problems, and list recommendations


 Phase II: Semi-Quantitative Diagnostics

The semi-quantitative diagnostics phase is entered if in the first phase solutions are not evident, or more complete documentation is required. This phase involves:
  • Detailed building inspection and pollutant source inventory to identify contaminate sources and potential pollutant pathways
  • Systematic measurement of temperature, relative humidity, airborne particles, CO2, and carbon monoxide (CO) - these are important indicators of comfort, and air filtration and ventilation effectiveness. CO is measured because of its ability to cause health effects at relatively low exposure levels
  • Review HVAC system documentation
  • Detailed HVAC system inspection
  • Evaluate HVAC operation and HVAC maintenance and hygiene programs
  • Report phase II findings and recommendations

Phase III - Quantitative Diagnostics

The third phase, if necessary, requires measuring building performance and more complex environmental monitoring. The measurements are conducted on the basis of hypotheses developed during the previous phases. These tests are to verify contaminant sources, ventilation system deficiencies, pollutant pathways, or other hypothesized factors regarding the reported health and comfort problems.
  • Environmental sampling - a comparative sampling strategy is used
  • Bulk material for microorganism analysis or voc emissions testing
  • Air sampling for volatile organic chemicals (voc) and formaldehyde
  • Airflow measurements - these may be made for comparison to design specifications, codes, and standards
  • Outdoor air

  • Supply air

  • Return air

  • Report of phase III findings and recommendations
