The importance of ventilation with Farmwood

Introduction

Adam Armour-Florence speaks with Nathan Wood, Managing Director of Farmwood, about the growing importance of indoor air quality and building health in the drive towards more energy-efficient homes.

Nathan shares insights from over two decades working across residential and commercial ventilation systems, discussing how retrofit projects can succeed or fail depending on whether ventilation is properly considered. The conversation explores the links between airtightness, moisture management, damp and mould, occupant behaviour and long-term building performance, while highlighting the risks of focusing solely on energy efficiency without considering the health and wellbeing of residents.

The episode also examines common challenges encountered in retrofit projects, the need for competent design and installation and the value of engaging residents so they understand how their homes are intended to operate. Through practical examples and industry experience, Nathan makes the case for treating ventilation as an essential part of the retrofit process, helping to create homes that are not only warmer and more efficient, but healthier places to live.
