The Photonic Breakthrough
Traditional stone blocks light – until HRST reengineered Blue Roma Quartzite into light-transmitting panels:
Material Modifications:
Thickness Optimization: 12mm (vs standard 30mm)
Resin-Free Backfilling: Silica aerogel infusion
Surface Texturing: Laser-etched diffuser patterns
Light Performance Metrics
| Thickness | Luminous Efficacy | Haze Ratio | CRI |
| 12mm | 78% | 27% | 92 |
| 18mm | 63% | 41% | 89 |
| 30mm | 31% | 68% | 84 |
Case Study: Seoul "Stone Lantern" Pavilion
428 backlit Blue Roma panels
IoT-controlled circadian lighting
Energy harvest: Integrated PV cells in framing
Outcomes:
83% daylight autonomy
42% reduction in artificial lighting
