This dataset comprises comprehensive digital models supporting the thermal-ventilation performance analysis presented in the associated study. It documents the spatial configuration and environmental adaptation mechanisms of a representative Hakka vernacular dwelling—the Wei Family Compound in Ganzhou, Jiangxi, China.

**Core Components**:
1. **CAD Architectural Drawings** (.dwg)
- Georeferenced floor plans, sections, and elevations (Scale: 1:100)
- Annotations of key passive elements: courtyards, cold alleys, material interfaces

2. **SketchUp 3D Model** (.skp)
- Geo-located massing (WGS84: 25.8502°N, 114.9355°E)
- Material assignments: Blue brick walls (U=1.2 W/m²K), timber roofs (ρ=650 kg/m³)
- Contextual terrain and vegetation (LOD 300)

**Methodological Significance**:
- Enables validation of the Hakka "courtyard-cold alley" microclimate regulation system
- Provides baseline models for reproducibility studies in hot-humid climates (Köppen: *Cfa*)
- Supports parametric extensions for green retrofit simulations (e.g., envelope insulation, shading)

**Ethical Compliance**:
- Building geometry anonymized; no identifiable household data included
- Cultural heritage protocols followed per *China’s Historic Building Conservation Guidelines*
