Musée de l’Orangerie Architecture: Oval Geometry and Light

The Orangerie is an exercise in gentle control. Elliptical rooms and top‑lit galleries modulate attention, preventing harsh specular highlights while bathing the Nymphéas in ambient, north‑weighted light.

🔷 Ellipse vs. Rectangle

• No corners, no rush: Edges curve; your eyes linger.
• Center of gravity: You naturally recenter; balance improves.

$$ ext{Ellipse Area} = pi a b quad ext{(vs rectangle } ab) Rightarrow ext{more perimeter for same area} $$

☀️ Skylight Strategy

• Indirect daylight: Diffusion panels reduce contrast spikes.
• Glare management: Seating avoids highest luminance fields.
• Color constancy: Neutral baffles preserve Monet’s chroma.

🧭 Wayfinding Minimalism

Architecture here is service to painting, not a spectacle.

[^docs]: Renovations documented proportional skylight transmittance to maintain tone stability.

🔬 Light Measurement Notes

• Target average illuminance: 100–150 lx on painting planes.
• Uniformity: keep ratio ≤ 3:1 between bright/dim zones.
• Spectral neutrality: avoid strong color casts in baffles.

$$ ext{Uniformity Index} = rac{E_{max}}{E_{min}} le 3 $$

🧱 Materials + Surfaces

• Neutral wall finish to prevent color drift.
• Matte floor to reduce glare bounce.
• Bench fabric with low reflectance.

❓ FAQ

• Why ellipses? → They slow movement and soften eye saccades.
• Why top‑light? → Keeps distractions off the perimeter walls.
