Code-compliant lighting design with photometric simulation for lux uniformity, energy density (W/m²), glare control (UGR), and occupant comfort.

What is UGR and why does it matter?

Unified Glare Rating (UGR) quantifies discomfort glare from luminaires. ISO 8995 / EN 12464 specify UGR limits for different tasks (e.g., UGR ≤ 19 for office work). Exceeding these limits can cause occupant discomfort, reduced productivity, and potential liability. Our simulation calculates UGR for every zone.

Key Deliverables

• DIALux Evo / Visual Lighting photometric simulation report
• Iso-lux contour plots for every space
• Fixture schedule with manufacturer specifications
• Energy density compliance check (W/m² targets)
• Glare assessment (UGR values per zone)

Do you design emergency lighting?

Yes. Emergency lighting (egress, exit signage, standby) is simulated separately to verify 10-lux minimum at floor level along egress paths, as required by OBC Part 3 and NFPA 101. This is often a critical path item for occupancy permits.
