BPI BA-T study plan

BPI BA-T · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

Building Science Fundamentals

  • Define heat, air, and moisture flow fundamentals in your own words and map each mechanism to a building assembly example

  • Explain the stack effect, wind-driven pressure, and mechanical pressure on a pressure map sketch of a two-story house

  • Differentiate conduction, convection, and radiation and compute a simple U-value from layer R-values

  • Identify the four control layers (water, air, thermal, vapor) and state where each belongs in a wall section

Your checkpoint

A one-page annotated wall-section diagram labeling all four control layers with a 300-word explanation of the driving forces acting on it

Week 2

Building Science Fundamentals & Building Assessment and Data Collection

  • Explain psychrometrics concepts (dew point, relative humidity, enthalpy) and locate condensation risk on a psychrometric chart

  • Compare vapor retarder strategies across climate zones and justify one choice per zone

  • Build a pre-site-visit checklist covering safety, access, and homeowner interview questions

  • Practice a 20-minute homeowner intake interview and record the questions that produced the most useful answers

Your checkpoint

A completed pre-site-visit checklist plus a written condensation-risk analysis for two assemblies in different climate zones

Week 3

Building Assessment and Data Collection

  • Assemble a field kit list for visual assessment, moisture screening, and photo documentation

  • Describe how to inspect attic, basement, crawlspace, and rim-joist areas for air leakage and moisture pathways

  • Outline a systematic room-by-room walkthrough sequence that avoids missed zones

  • Record observations using objective, non-diagnostic language rather than conclusions

Your checkpoint

A reusable room-by-room assessment form with at least 20 observation fields and a sample completed entry

Week 4

Building Assessment and Data Collection & Diagnostic Testing and Measurement

  • Explain blower door test setup, depressurization targets, and what CFM50 represents

  • Interpret a blower door report and convert leakage to a leakage-area or ACH50 estimate

  • Describe infrared thermography basics: emissivity, Delta-T requirements, and common false readings

  • Plan a combined blower door plus thermal imaging walkthrough and sequence the steps

Your checkpoint

A written test plan for one house specifying blower door setup, imaging sequence, and the conditions required for valid readings

Week 5

Diagnostic Testing and Measurement

  • Demonstrate duct leakage testing concepts and explain the difference between total and outside duct leakage

  • Explain combustion safety testing: draft measurement, spillage, and CO thresholds for action

  • Describe moisture measurement methods and where pin versus pinless meters are appropriate

  • State calibration, baseline, and repeatability practices for each instrument covered

Your checkpoint

A diagnostic protocol sheet covering blower door, duct leakage, combustion safety, and moisture testing with pass/fail criteria for each

Week 6

Diagnostic Testing and Measurement & Field Documentation and Reporting

  • Convert raw test readings into a findings summary that separates measurement from interpretation

  • Draft findings statements that pair each observation with its evidence and its limitation

  • Structure a report with sections for scope, methods, measurements, findings, and recommended next steps

  • Write photo captions that state location, condition, and measurement without overstating certainty

Your checkpoint

A complete mock report for one house including at least 8 captioned photos and a findings table linking evidence to recommendation

Week 7

Field Documentation and Reporting

  • Review your mock report against a documentation standards checklist and log every gap

  • Rewrite three findings to remove speculation and add missing evidence references

  • Explain record retention, chain of custody, and liability considerations for field data

  • Practice a client debrief that translates technical findings into plain-language priorities

Your checkpoint

A revised final report with a tracked change log showing at least 10 corrections from the standards review

Week 8

Building Science Fundamentals & Building Assessment and Data Collection & Diagnostic Testing and Measurement & Field Documentation and Reporting

  • Complete a timed 60-question mixed-domain practice set and score by domain

  • Re-teach your two weakest domain concepts in a short written summary without notes

  • Build a one-page formula and reference sheet for diagnostics and unit conversions

  • Rehearse the full workflow from intake to report delivery end to end

Your checkpoint

A scored practice exam with a per-domain error analysis and a finalized one-page reference sheet

Milestones

Week 2: Can explain all four control layers and condensation risk for two climate zones without notes, scoring at least 80% on a self-made 15-question quiz

Week 4: Can describe blower door setup and interpret a sample report, correctly converting CFM50 to ACH50 in a worked example

Week 6: Mock report includes all required sections, at least 8 captioned photos, and findings that cite specific measurements

Week 8: Practice exam score of 80% or higher overall with no domain below 70%, and error log reviewed
