DOE and BPI-Driven Curriculum

WeatherCert covers the Basic and Core Competencies for Weatherization Installer & Energy Auditor jobs required by the Department of Energy’s (DOE) Weatherization Assistance Program. The lab also prepares students to sit for and pass the online and field exams for the Building Performance Institute (BPI) Building Analyst and Envelope Professional certifications.

Diagnostic House

A Hands-On training System

WeatherCert creates simulated environments in the classroom through the use of a self-contained Diagnostic House and various modules. Students who complete the course gain skills and knowledge through hands-on training and are exceptionally well prepared for the BPI exams.

Comprehensive, Flexible, and Turn-Key

Though this system is comprehensive, instructors easily train, manage, and monitor each student’s progress. They are free to tailor their classes to meet unique teaching goals, physical classroom restrictions, and student needs.

Total course time can be shortened or extended and special emphasis can be given to any particular industry, technology, or installation type. Instructor training and certification are available, and lab configurations are limited only by an instructor’s imagination.

Lab Components

Diagnostic House

The diagnostic house is a 7’ by 7’ by 7’ simulated house complete with a living space and attic. Designed to withstand the elements and allow student to both identify and perform weatherization techniques, each diagnostic house includes standard sized windows and doors and interchangeable ceiling panels equipped with a variety of common household ceiling fixtures and ventilation units.

Modules01Diagnostic House Modules

The following modified ceiling panels replace some of the standard house ceiling panels and are used to perform various weatherization tests.

Recessed Lighting Fixture – A lighting fixture mounted in a removable house-ceiling panel.

Combustion Appliance Vent – Used to vent Combustion Appliance Work Station into house attic space for Worst Case Depressurization Test, Spillage Test, and Vent Draft Test.

Exhaust Fan – Used to measure exhaust fan flow.

Duct Leak – Used to measure airflow in a duct leak.

Leak Insertion Window – Includes multiple faults and provides easy access so instructors can control simulated air leaks for pressurization tests.


Diagnostic House Exercises and Tasks

  • Proper and improper installation examples
  • Wall and attic insulation installation
  • Weather stripping
  • Exhaust fan air flow measurement
  • Set up blower door for depressurization test
  • Perform blower door depressurization test
  • Perform pressure diagnostics
  • Measure air leakage using leak insertion window
  • Worst-Case Combustion Appliance Zone (CAZ) Depressurization Test
  • Spillage evaluation and carbon monoxide and draft measurements

Training Aids

In addition to Theory, PowerPoint,and Exercise Worksheets students can demonstrate effects corresponding to the theory instruction. Two main training aids are.

Training AidsPressure House – Students are introduced to back drafting as well as an introduction to testing with a Pressure and Flow Gauge.

Stack Effect – Warm air rises, cold air falls. This cycle is called stack effect, and as a result there is a “Neutral Zone” in between. Students can demonstrate their understanding using the Stack Effect Training Aid.
