Ventilation is essential to how modern homes function. As buildings become increasingly airtight, fresh air can no longer be left to chance. Without a dedicated ventilation strategy, homes are more likely to suffer from moisture build-up, poor air quality, and inconsistent comfort.

Solutionair designs whole-home ventilation systems that are fully integrated into the building. Using Mechanical Ventilation with Heat Recovery (MVHR) and other balanced ventilation solutions, we continuously supply fresh, filtered air while removing stale, moisture-laden air. These systems are engineered to operate quietly, efficiently, and in harmony with the home’s overall design.

Ventilation is essential to how modern homes function.

As buildings become increasingly airtight, fresh air can no longer be left to chance. Without a dedicated ventilation strategy, homes are more likely to suffer from moisture build-up, poor air quality, and inconsistent comfort.

Solutionair designs whole-home ventilation systems that are fully integrated into the building. Using Mechanical Ventilation with Heat Recovery (MVHR) and other balanced ventilation solutions, we continuously supply fresh, filtered air while removing stale, moisture-laden air. These systems are engineered to operate quietly, efficiently, and in harmony with the home’s overall design.

Scope of use
  • New builds and major renovations
    • Airtight or energy-efficient homes
    • Architecturally designed residences
    • Homes experiencing condensation, moisture, or air quality concerns
Why it matters

Poorly planned ventilation is one of the leading causes of condensation, mould, and unhealthy indoor environments. Relying on open windows is unreliable, uncomfortable, and energy-inefficient—particularly in colder months or high-humidity conditions.

A professionally designed balanced ventilation system protects both occupants and the building itself. By addressing ventilation early in the design process, homes achieve cleaner air, better thermal performance, and consistent comfort throughout the year.

How it works
  • Ventilation strategy is developed based on the building layout, usage of rooms, occupancy, climate, and to meet NZ building code.
  • Mechanical Ventilation with Heat Recovery systems are designed to extract stale air from wet areas while supplying fresh air to living spaces and bedrooms.
  • Heat exchangers recover warmth from outgoing air and transfer it to incoming air, reducing energy loss.
  • Duct layouts, plant locations, and air distribution are coordinated to integrate cleanly within the architectural design. 
For specifiers

Scope of design

  • Whole-home balanced ventilation system design
  • Supply and extract air distribution planning
  • Integration with heating and cooling systems

System considerations

  • Mechanical Ventilation with Heat Recovery units selected based on airflow, pressure, and efficiency requirements
  • Heat recovery efficiencies typically in the range of 80–90%
  • Filtration strategies to manage outdoor pollutants, pollen, and fine dust
  • Summer bypass and control strategies where appropriate

Design and coordination value

  • Neutral pressure ventilation to protect building fabric
  • Early integration into ceiling zones, service cavities, and plant spaces
  • Reduced risk of condensation and hidden moisture issues
  • Clear basis for coordination across architectural, services, and construction documentation

Typical outputs

  • Ventilation system layouts and air distribution strategy
  • Unit performance criteria and airflow requirements
    Inputs suitable for coordinated design and installation
