System Comparison
The Five Candidate Systems
| System | Best for | Delivery model |
|---|---|---|
| Unitized | High-rise, fast programme, factory-consolidated quality | Panelised fabrication at Qingpu |
| Stick Built | Low-rise and irregular geometry, site-assembled | Site-assembled mullions and transoms |
| Double Skin | Deep ventilation cavity for thermal and acoustic strategy | Two-envelope configuration |
| Rainscreen | Open ventilated cavity behind stone or metal cladding | Drained and ventilated detailing |
| BIPV | Photovoltaic integration within the envelope | Module-integrated assembly |
The selector recommends a starting system; the engineering team verifies it against your brief.

The Systems
What each system is best at
Stick Built Curtain Wall
Site-assembled mullion/transom grid. The value champion for mid-rise and phased programs.
Double Skin Facade
Two glazing skins around a ventilated cavity: best-in-class acoustics, natural ventilation and energy.
Point-Supported Glazing
Frameless glass held by spider fittings. The signature look for lobbies, atriums and curved glazing.
Rainscreen Cladding
Stone, terracotta or GRC panels on a drained cavity: mass aesthetics with A1 fire options.
Metal Roof & Wall
Standing-seam metal skins for big-span roofs, airports and logistics — fast and economical.
FAQ
System selection questions, answered
Answer five questions about height, speed, geometry, performance priority and budget. Each answer adds scores to candidate systems, and the tool returns a ranked recommendation with reasons and links to the relevant product pages.
Unitized curtain wall is the standard recommendation above 50–60 m: factory QC, faster erection by crane, and a closed rain-screen layer during installation. Below that, stick built is usually more cost-effective.
Double skin facades create an air cavity between two glazing layers for natural ventilation, acoustic shielding and lower energy demand — selected when sustainability or acoustic performance outranks first cost.
No — the tool is a shortlist generator. Hanart engineers confirm the recommendation with structural, thermal and buildability studies, and typically validate the system with a mock-up test before fabrication.
