Passive House
Innovative Passive House Ventilation for a Balmain Heritage Home Renovation
Client Requirements
The client was particularly interested in an all-in-one solution that would provide heat recovery ventilation (fresh, filtered air while recovering heat from outgoing air), dehumidification to prevent condensation and mould, and energy-efficient heating and cooling for year-round comfort.
Our Custom Ventilation Solution
To meet the client’s needs, our team installed the HIDEW RER 100I – a state-of-the-art system designed for high-performance homes. This advanced unit integrates ventilation, heating, cooling, and dehumidification, making it ideal for Passive House projects.

Key Components Installed
- HIDEW RER 100I — A powerful and efficient all-in-one air treatment system.
- Ducting System — Custom-designed to ensure balanced airflow throughout the home.
- Water Chiller — Enabling highly efficient temperature control.
- Hydraulic Fittings & Pipes — Ensuring seamless operation and system efficiency.
- Buffer Tank & Expansion Tank — Providing stability and improved energy management.
Challenges and Solutions
Working on a heritage home presents unique challenges, particularly in integrating modern ventilation technology into an existing structure. Our expert team carefully designed a solution that seamlessly blended with the home’s character while delivering high energy efficiency and indoor comfort — navigating space constraints, meeting Passive House airtightness and insulation standards, and optimising heating, cooling and air exchange without excessive energy consumption.
Final Outcome
The result is a highly efficient, comfortable, and healthy indoor environment that aligns with Passive House principles. The home now benefits from consistently fresh and filtered air, reduced humidity and improved indoor air quality, energy-efficient heating and cooling, and lower energy costs with a reduced carbon footprint.
