International Verifier Level 1

The goal of the Building Science Institute (BSI) International Verifier certification scheme is to familiarize candidates outside the United States with the structure of the IECC, ANSI 301, ANSI 380, and ENERGY STAR® New Homes program. There is a specific need for those pursuing LEED Residential™ certification to be able to capture data related to the energy conservation goals of the project, and meet the requirements listed in the GBCI LEED Addenda #10443.

An International Verifier is credentialed by the Building Science Institute, and qualified to perform verification and testing in conformance with ANSI 301 and ANSI 380, understand the International Energy Conservation Code (IECC), and verify compliance (NOT certification) with ENERGY STAR program requirements.

BSI International Verifier, Level 1 Required Training

Prior to certification, candidates must successfully complete the following training programs (all hosted for BSI through Intellectual Ferret):

  1. The Residential Construction Guide 1
    • Terminology
    • Building Science
    • Comfort
    • Design
    • HVAC Design
    • Development
    • Construction Management
  1. IECC Certification Training (2015, 2018, or 2021)
  2. BSI Verifier Training
  3. ANSI/RESNET/ICC 301 training
  4. ENERGY STAR Single-Family New Construction
        • ENERGY STAR Single-Family New Construction Exam
        • Must be proctored by BSI, completed after the ENERGY STAR Single-Family New Construction workshop
  1. HouseRater Training
      • HouseRater Comprehensive On-boarding
      • How to Energy Model in HouseRater
        • 10 Projected Energy Models using case study materials will be completed by the end of this workshop
      • How to Use the HouseRater Inspection App

Completion of the above coursework will satisfy the requirements to be certified as a “BSI International Verifier, Level 1”. Individuals certified will have the understanding of building science fundamentals, air sealing and insulation inspections, and how to perform air infiltration and duct leakage tests, in order to comply with the GBCI LEED Addenda #10443.

After completing the prerequisite coursework, candidates will submit an International Verifier application. This will formally request the certification, and present any additional certifications such as the ASHRAE BCxP to BSI for consideration.

Upon successful application and review, the credentialed individual will be listed under BSI’s Verifier Registry, with the explicit note the certification is only applicable outside of the United States of America.
