What we offer
Four specialist services.
Compliance-ready
Car Park Ventilation Design
Full engineering design for car park ventilation systems compliant with AS1668.2. We handle the calculations, fan selection, duct layouts, and documentation so your project clears consent without back-and-forth.
What's included
- AS1668.2 compliance calculations
- Jet fan and duct layout design
- Product selection with full specifications
- Optional CFD modelling for complex geometries
- Cost estimate with specified products
Advanced simulation
CFD Analysis
Computational Fluid Dynamics modelling for spaces where standard calculations aren't enough. We simulate airflow around obstructions, model multiple scenarios, and produce visual reports that satisfy engineers and consent authorities.
What's included
- 3D airflow simulation in enclosed spaces
- Multiple scenario modelling
- Visual output with velocity vectors and contour maps
- Smoke extraction & CO dilution verification
- Engineer-signed report for consent
Heavy-duty environments
Industrial Ventilation Design
Ventilation engineering for warehouses, factories, workshops, and processing facilities. We address heat load, condensation, exhaust pollutants, and regulatory requirements — and specify the exact products to meet them.
What's included
- Heat load and airflow calculations
- Destratification fan layouts
- Pollutant dilution and exhaust design
- HVLS fan selection and placement
- Compliance with WorkSafe ventilation standards
Residential expertise
Domestic Ventilation Design
Whole-home ventilation strategies for new builds and retrofits. Heat transfer systems, sub-floor moisture control, bathroom and kitchen extraction — designed to the NZ Building Code and specified for energy efficiency.
What's included
- NZ Building Code compliance (G4, H1)
- Heat transfer system layouts
- Sub-floor ventilation to prevent moisture and mould
- Bathroom and kitchen extraction design
- Energy recovery unit sizing
How it works
From drawings to deliverables — four steps.
Submit your drawings
Send us your architectural or structural drawings — no cost, no commitment. PDF or DWG both work.
Engineering assessment
Our team reviews the scope, identifies compliance requirements, and proposes an approach within 2–3 business days.
Design & specification
We produce the full design package — calculations, layout drawings, product schedules, and documentation.
Handover & support
Final deliverables, product pricing, and ongoing support through the installation and consent process.
