What you need to know
Homestar v5 introduced the requirement for continuous mechanical ventilation in homes. Following previous webinars covering why this is important, in this session we’ll discuss how to make sure the chosen system is working properly. Join us to hear tips and learning from the field, and some fundamentals concepts of good system design, including sizing and location of fans and ducts, selection of other system components and how to do basic commissioning.
Getting ventilation right is important for maintaining comfort and minimising the risk of condensation and mould. Most residential designers don’t have the benefit of working dedicated mechanical services engineers on housing projects. During this session, we’ll take some important concepts of ventilation to help residential designers avoid common issues such as noise, draughts or inadequate air flow.

We also run regular webinars examining specific products and materials, and their relationship with green building certifications.
Demand for these webinars is increasing as our members ask for a range of themes and topic to build market readiness for the increased focus on carbon and the changes coming through certifications.
