The Larry & Jason Show

In this episode, we explore the evolving world of Ventilation System Design with a focus on practical challenges, industry trends, and the shift towards heat recovery solutions.

Catherine Theakston, our System Design Supervisor, shares insights from nearly two decades in system design, discussing the transition from manual CAD processes to advanced Revit software, the growing popularity of heat recovery and semi-rigid ducting, and the importance of accurate, regulation-compliant designs.

The discussion covers:

• Key changes in ventilation design technology and workflow

• The rise of heat recovery and semi-rigid ducting as industry standards

• What’s needed to request a professional ventilation design

• The importance of experience and knowledge in delivering effective solutions

This episode reflects on the journey behind the number, exploring what reaching 3 million installations represents for envirovent, the wider ventilation industry, and the customers who have trusted our solutions over the years.

From steady growth to long‑term commitment to better indoor air quality, the conversation looks at how this achievement was made possible and what it signals for the future.

Whether you’ve been part of the journey or are just discovering envirovent, this episode offers insight into the progress, people and purpose behind the milestone.

In this episode, we’re joined by Ruth MacEachern, Product Manager and Policy Advisor at envirovent, for an in‑depth conversation about building regulations, competency, and where ventilation is heading next. Ruth shares her experience working across different roles within envirovent, her academic background in building control, and why making regulations clear, practical and accessible is critical for everyone involved in the built environment. The discussion covers:

• Why competency and education remain key challenges in compliance

• Insights from studying building control and Future Home Standards

• How regulation, policy and education can better support well‑ventilated buildings

This episode is ideal for anyone working in ventilation, housing, construction, building control or compliance who wants clearer insight into regulations.
