- Chapter 1 – The Investigative MindsetYour first step is a shift in mindset: you're not just collecting samples, you're building a case. This chapter sets the CIEIT foundation—evidence over assumption, hypothesis over guesswork.4
- Chapter 2 – Human Factors & CommunicationPeople are your best sensors. Learn how to run intake that captures the real story, cluster symptoms, and speak to clients in a way that builds trust and clarity.4
- Chapter 3 – The Building as a SystemBuildings breathe, leak, and respond to weather and use. This chapter ties construction type, envelope, and history to airflow and IAQ so you see the building as one system.4
- Chapter 4 – Pressure & PhysicsPressure is invisible but drives where air and contaminants go. Master the physics, then measure it—stack effect, zone pressure, and pressure-driven transport.4
- Chapter 5 – Advanced HVAC InteractionHVAC can fix or worsen IAQ. Learn static pressure (TESP), oversizing, short-cycling, and ventilation effectiveness so you diagnose system-driven problems with confidence.4
- Chapter 6 – Moisture & Vapor ForensicsMoisture drives mold, odor, and decay. Follow moisture in all its forms—liquid, vapor, and capillary—and connect vapor drive and thermal bridging to real-world damage.4
- Chapter 7 – Specialized Investigations: ChemicalChemical complaints need a clear approach: intake, measurement tools (including PIDs where appropriate), and source tracing—plus how to explain findings to clients.3
- Chapter 8 – Specialized Investigations: ParticulateParticulate type and size drive health and comfort. Learn what to sample, how to interpret data, and how it fits into the larger investigation and report.3
- Chapter 9 – Specialized Investigations: PathogensPathogen investigations tie biology to building conditions. Focus on moisture linkage, sampling protocols, chain of custody, and guiding clients toward remediation.3
- Chapter 10 – Specialized Investigations: Wildfire SmokeWildfire events demand clear assessment and messaging. Learn infiltration pathways, filtration and pressurization, and how to talk to building owners during and after events.2
- Chapter 11 – The Root-Cause ReportYour work lives in the report. This chapter is about evidence chain, documentation standards, and writing reports that are clear, defensible, and useful to clients and other professionals.3
- Chapter 12 – Expert Ethics & BusinessClose the loop: ethics, authority positioning, and the business of being a CIEIT specialist. Communicate like an expert, set boundaries, and position yourself for high-fee, high-trust work.3
