立面设计
Overview
The facade is the building's public face and its weather shield. This skill covers facade composition — proportional systems, material layers, fenestration logic, and the technical details that keep water out.
When to Use
- Designing a new building's exterior skin
- Rationing window-to-wall ratio for energy or aesthetic goals
- Selecting cladding materials (brick, stone, metal panel, timber)
- Detailing curtain walls or rainscreen assemblies
Key Principles
- Proportional system — use a grid (golden ratio, modular, or custom) to unify openings and solid panels.
- Layer logic — every facade has layers: structure, insulation, air barrier, cladding, glazing.
- Fenestration rhythm — window spacing and size create visual rhythm; vary sparingly for emphasis.
- Shadow play — deep reveals, fins, and overhangs add depth and reduce solar gain.
- Material honesty — let each material read as itself; avoid faux finishes.
Process
- Establish proportional grid from the structural module.
- Place primary openings (windows, doors) on grid lines.
- Select cladding material — consider weathering, maintenance, and cost.
- Detail junctions: base, head, corners, and penetrations.
- Specify weather barrier, insulation, and drainage plane.
- Review at 1:20 and 1:5 scales for constructability.
Common Pitfalls
- Ignoring thermal bridging at slab edges and mullions.
- Mixing too many materials — limit to 2-3 for coherence.
- Flat facades with no depth — shadow lines matter.
- Undersized drip edges — water staining follows.
Verification Checklist
- [ ] Proportional grid applied consistently
- [ ] Window-to-wall ratio meets energy code
- [ ] All junctions detailed at 1:5 or larger
- [ ] Rainscreen drainage and ventilation verified
- [ ] Material palette limited to 2-3 elements
