Heating, cooling and ventilation systems are central to how a home feels, functions, and performs year-round. In modern, airtight homes, these systems must be carefully designed to work in balance with building design and the building envelope to deliver consistent, reliable comfort.

Solutionair designs integrated heating, cooling and ventilation solutions guided by detailed thermal modelling and load analysis. Rather than relying on generic assumptions, each system is tailored to the specific characteristics of the home—its layout, construction, orientation, and occupancy patterns—ensuring precise and responsive performance.

Heating, cooling and ventilation systems are central to how a home feels, functions, and performs year-round.

In modern, airtight homes, these systems must be carefully designed to work in balance with building design and the building envelope to deliver consistent, reliable comfort.

Solutionair designs integrated heating, cooling and ventilation solutions guided by detailed thermal modelling and load analysis. Rather than relying on generic assumptions, each system is tailored to the specific characteristics of the home—its layout, construction, orientation, and occupancy patterns—ensuring precise and responsive performance.

Scope of use
  • New builds and major renovations
  • Architecturally designed homes
  • Airtight or energy-efficient buildings
  • Projects where comfort, efficiency, and predictability are priorities
Why it matters

Incorrectly sized or poorly coordinated systems are a common cause of uneven temperatures and over- or underventilation, leading to unnecessary energy consumption and ongoing comfort issues. Too often, heating and cooling systems are selected without a clear understanding of how the home will perform once built.

By designing systems based on measured loads and real-world conditions, Solutionair delivers predictable comfort, improved efficiency, and long-term reliability. The result is a home that maintains the right temperature with minimal energy use—season after season.

How it works
  • Heating and cooling loads are established through thermal modelling and air supply and extraction requirements through ventilation load calculations.
  • System selection is informed by building layout, insulation levels, glazing, airtightness, and ventilation strategy.
  • Heating, cooling and ventilation solutions are designed to operate efficiently across seasonal conditions.
  • System layouts and control strategies are coordinated to support consistent comfort and low operating costs.
For specifiers

Scope of design

  • Integrated heating, cooling and ventilation system design
  • Coordination with ventilation and overall HVAC strategy
  • Consideration of room-by-room performance requirements

System considerations

  • System sizing based on calculated loads rather than rule-of-thumb values
  • Selection informed by efficiency, acoustic performance, and control requirements
  • Integration with ventilation systems to support humidity management and comfort
  • Compatibility with high-performance and airtight building envelopes

Design and coordination value

  • Reduced risk of oversizing or underperformance
  • Improved temperature consistency across the home
  • Cleaner integration into architectural layouts
  • Fewer compromises during installation and commissioning

Typical outputs

  • Heating, cooling and ventilation system performance criteria
  • Space-specific load data to inform system selection
  • Coordinated design inputs suitable for construction documentation
