Ventilation and indoor air quality in passivhaus buildings & EECN

Start date: 07/02/2022
Final date: 18/2/2022

When a client says to you, “In our Passivhaus I sleep less but I feel more rested in the morning!”, what is she talking about? She’s talking about what it’s like to live with a whole-house balanced mechanical ventilation system with heat recovery: a solution that provides a 100% fresh and filtered air, preheated by the outgoing air, where pollutants, VOC’s and moisture are continually extracted to the outside, 24 hours a day.

Designing, installing, and commissioning this type of system is not rocket science, but too often it’s done wrong, and performance is far from expected, with noise being the common culprit. There are solutions: in this course you’ll learn the key points related to the design, installation, control and commissioning of mechanical ventilation systems with heat recovery for high-performance Passivhaus and nearly-zero energy buildings. Whether you are a certified Passivhaus Designer or Tradesperson looking for a refresher course, or new to the field of mechanical ventilation systems, the course will give you the tools to size equipment and components to best suit your project, and perform basic on-site supervision to make sure the installation is done properly.
