Why Attend This Course

We Have Tighter Building Envelopes.  Like many jurisdictions around the country, Maine is making significant investments to improve the energy performance of its new and existing housing stock.  All new home construction must now comply with the 2015 International Energy Conservation Code.

We Use Minimum Ventilation Requirements.  Maine’s mandatory residential ventilation code, the ASHRAE 62.2-2016 standard (Ventilation and Acceptable Indoor Air Quality in Low-Rise Residential Buildings), informs residential professionals about how much ventilation air is required in a home. But ASHRAE 62.2 does not inform professionals on specific strategies to implement the standard.

Current Practice Is Not Best Practice. The standard practice until now has usually been to meet the provisions of the ASHRAE 62.2 minimum ventilation code through installation of exhaust-only ventilation.  Not only is this strategy energy-inefficient, it fails to deliver fresh air to and exhaust pollutants from key areas of a home, such as living rooms and bedrooms (where people typically spend most of their time).

The Solution.  The use of recovery ventilation (such as Energy Recovery Ventilation or ERV) solves these challenges by delivering fresh air to and exhausting pollutants from multiple points in a home, not just kitchens and bathrooms.  And, using recovery ventilation in high performance homes captures a significant amount of outgoing thermal energy that otherwise is lost to the outdoors.  Energy recovery ventilation is usually the best option for people, buildings, and the planet.

Learn How.  Until now, there has been no opportunity for Maine residential professionals to learn how to properly design and install energy-recovery ventilation.  Attendees of this course will gain practical instruction on how to both design and install residential ventilation to meet North America’s only ventilation installation standard, the CSA F326 standard.  Participants will use extensive worksheets in conjunction with detailed procedures to select equipment, size ducts and specify installation and control details necessary to design ventilation systems that satisfy both the ASHRAE 62.2 building code requirement, and the CSA F326 installation standard.

Learning Objectives

Attendees will learn how to:

  • Calculate the required ventilation and exhaust requirements for residential ventilation systems
  • Assess the risk from depressurization and size make-up air systems to suit
  • Describe the distribution requirements
  • Select ventilation equipment to meet the requirements of both ASHRAE 62.2 and CSA F326
  • Size ducting according to good engineering practice without the limitations of building code-based tables
  • Describe the controls required under CSA F326
  • Calculate delivered and mixed air temperatures to ensure occupant comfort

About the Presenter:

Kurt Johnson, HRAI-Certified Ventilation Installer and Approved HRAI CSA F326 Trainer: 

Kurt Johnson has been the owner of Fresh Air Ventilation Systems, LLC for the last 16 years. While selling Canadian Modular homes he became aware of the need for a professional air exchange company. He went to Heating Refrigeration Air Conditioning Institute of Canada (HRAI) and earned his certification in Residential Mechanical Ventilation Design and Installation (the same certification offered through this upcoming course). 750 air exchangers and installed over 1000 systems in stick built, modular, and existing homes. About 50% of those installs were in existing homes.

Kurt has been on Board of Directors of the Maine Indoor Air Quality Council for 11 years and has served as the President and Treasurer. He has also attended many building science seminars around the country and has presented both at the annual MIAQC and IAQA conferences. He also has presented at various ventilation seminars for many different groups including Breathe Easy Coalition, MECHIPS, MABEP, BPI and the Maine Building Officials and Inspectors Association conference.
