TRAINING

CRESNET offers multiple accreditation paths and training options. Check back regularly for new training opportunities.

CRESNET ACCREDITATION COURSES

CRESNET offers 3 Accreditation Courses.  The training is deigned to take you from first principles of air leakage through house inspections, recording, air tightness testing to the use of energy modelling software and reporting.The courses must be completed as follows:


Accredited Building Code Energy Modeller (BCEM) -This course broken down into 6-8 sessions done virtually or it can be 2 ½ day training course where lessons, examples and practice activities are provided. It demonstrates the REM/Rate software, how to use it and how it applies to providing the performance reports required to submit for permit for Code Compliance. There is a challenge quiz to complete this course to demonstrate your knowledge gained from taking this course.


Accredited Air Tightness Tester (ATT) Course -This is course 1 day course offered virtually or in person that discusses the onsite process using particular equipment to take readings of the air tightness of a home. There is a challenge quiz to complete this course to demonstrate your knowledge gained from taking this course. Once the course has been taken and the challenge quiz has been passed the applicant will also be required to have a mentorship completed on 3 homes to show competency which helps to provide quality assurance. 


Accredited Field Inspector Course - This is a 1 day course that shows how to take the data collected from the air tightness test on a home and input that data back into the original REM/Rate file that was created for permit for Code Compliance (projected Rating). There is a challenge quiz to complete this course to demonstrate your knowledge gained from taking this course. Once the course has been taken and the challenge quiz has been passed the applicant will also be required to have a mentorship completed on 3 homes to show competency which helps to provide quality control assurance. Candidates must find a recognized mentor and extra fees will be required.


Accreditated HERS Energy Rater - This designation is applied after you have completed all 3 of the above courses.

AIR TIGHTNESS TRAINING SESSION

UPCOMING TRAINING

Complimentary Introduction to Air Tightness Testing

 Date: Tuesday, October 21, 2025 

Time: 2:00 PM – 4:00 PM (Online via Zoom) 

RSVP by: Friday, October 17, 2025 

Why Attend?

This complimentary 2-hour session introduces the fundamentals of air tightness testing—what it is, when it’s used, and the valuable insights it provides during site visits. This session lays the groundwork for understanding how air tightness impacts building performance and code compliance. Open to all OBOA members in all roles. 

Topics Covered

  • How air leakage affects building energy use
  • SB-12 Chapter 3: Using air tightness to offset high window-to-wall ratios (>17%)
  • Code compliance via performance paths (e.g., Energy Star)
  • How wind and temperature influence air tightness in modern construction
  • Requirements for power-vented combustion equipment over 50,000 BTU/hr
  • Testing methods in CGSB 149.1-2019: single-point, two-point, and multi-point
  • OBC air tightness standards: 3 ACH for detached, 3.5 ACH for attached housing
  • Measuring at 50PA using ACH, NLR, and NLA—why NLR is the most accurate
