Attached Reflectance Calculator+Folk Taboo Database+Color Aging Prediction Model
1、 Color Science: How Roof Colors Affect Building Energy Consumption
1. Color temperature correlation experimental data
| Color Name | Solar Reflectance (SRI) | Surface Temperature Difference (℃) | Air Conditioning Energy Consumption Difference |
|---|---|---|---|
| Traditional clay red | 32 | +7.8 | +23% |
| SKW Carbon Grey | 95 | -4.2 | -37% |
| Cultural peacock blue | 68 | +1.5 | -12% |
2. Actual measurement of historical districts in Penang, Malaysia
George Town Case:
Traditional zinc sheet roof (dark gray):
-Attic temperature peak 51 ℃
-Annual paint maintenance cost $18/m ²
SKW Solution:
Cold Jadeite Color Stone Tile (SRI 82):
-The peak temperature drops to 39 ℃2、 Cultural Code: Southeast Asian Rooftop Color Taboos and Symbolic System
1. Religious and Folk Color Standards
| Region | Forbidden Colors | Recommended Colors | Symbolic Significance |
|---|---|---|---|
| Bali | All black roof | Terracotta orange+Sacred gray gradient | Connecting the gods of heaven and earth |
| Kelantan State | Bright Yellow | Emerald Green+Gold Thread Border | Royal Prestige |
| Bangkok | Pure White | Fragrant Rice Gold+Lotus Pink Stripes | Buddhist Purity |
2. Deconstruction of Color Standards for Royal Architecture
-Thai Ninth Royal Palace Standard :
-Main color: Pantone 18-1440 (Siamese gold)
-Auxiliary color: Pantone 19-4057 (Royal Blue)
-Forbidden: Any purple color (exclusive to the royal family)

-Selective reflection of infrared radiation (wavelength 700-2500nm) - Cultural color layer :
-Inorganic mineral pigment (weather resistance Δ E ＜ 1.5)
-Support RAL/NCS/Santone full color gamut - Self cleaning layer :
-Fluorosilane superhydrophobic coating (contact angle 172 °) - Anti glare layer:
-The haze value is controlled at 8-12% (EN 410 standard)
2. Color Durability Laboratory Data
| Test Project | Traditional Coatings | SKW Nano Coating |
|---|---|---|
| UV aging | Δ E>5 after 500h | Δ E<1.8 after 3000h |
| Acid rain corrosion | 48h foaming and peeling | 720h no change |
| Algae attachment rate | 92% | 8% |
