Global Dataset: This analysis includes 674 timber building projects across 26+ countries. WUI (Wood Usage Intensity) mean is 0.280 m³/m², median 0.235 m³/m², range 0.000–5.333. Patterns below reflect the full dataset.
Key Findings:
Sector spread: Pavilion structures have the highest WUI (mean 1.146, n=9) — small, bespoke builds use proportionally more timber. Domestic sector is second (0.509, n=22). Hotel (0.318, n=29) and Civic & Public (0.285, n=74) sit near the overall mean.
Material type: All-Timber systems average 0.402 WUI vs Mixed Composite at 0.166 — a 2.4× difference across the material spectrum.
Structural type: Frame systems are most efficient (WUI 0.223); Panel systems are highest (0.373). Volumetric sits mid-range (0.342).
Height threshold: High-rise buildings (>18m) are more efficient than lower buildings: WUI 0.233 vs 0.322 — larger structures spread timber volume over greater area.
Building type: Extensions are more efficient than New Builds: WUI 0.196 vs 0.287.

Compare WUI Across Categories
This chart shows mean Wood Usage Intensity (WUI) grouped by different categorical variables.
Longer bars indicate higher timber intensity per square meter.
WUI Distribution
This histogram shows how WUI values are distributed across all projects.
Most projects cluster around 0.2–0.4 WUI, with outliers reaching up to 5.3.
Structure Type × Material Purity Matrix
This heatmap reveals the interaction between structural systems and material choices.
Darker cells show higher WUI values, and larger cells indicate more projects in that combination.
