Christchurch: Fresh-air cooling for sealed summer homes

Christchurch, New Zealand — Modern, airtight homes are brilliant for winter efficiency but can feel stuffy in summer—especially when the AC is doing all the work. FAS Energy is tackling that challenge by pairing energy-recovery ventilation (Lossnay-style balanced ventilation) with ducted air conditioning so families enjoy cool temperatures and fresher indoor air during Canterbury’s hot, dry afternoons.

The design starts with a walk-through of your layout: where people sleep, cook, and gather; how sun and glazing load each room; and any hayfever or humidity concerns. Supply and extract grilles are mapped to keep air moving quietly through bedrooms and living areas while the energy-recovery core tempers incoming air. Controls are set for summer—bypass mode when evening air is favourable, gentle background ventilation to reduce CO₂, and fan profiles coordinated with the ducted system for low noise.

“When cooling and fresh air work together, rooms feel calm rather than cold,” said a spokesperson for FAS Energy. “You cut stuffiness, ease pollen, and keep power use sensible.”

What FAS Energy delivers:

- Balanced, filtered ventilation that eases AC load
- Duct design for quiet supply and effective return paths
- Filter selection and care for peak pollen months
- Tidy, coordinated installation and a full controls walkthrough
