Install illuminance sensors at representative artwork positions throughout galleries. Connect to building management system that logs lux levels and operating hours continuously. Set annual exposure budgets based on conservation policy (e.g., 150,000 lux-hours for oils, 50,000 for works on paper). Dashboard shows real-time exposure accumulation with projections. Alert at 75%, 90%, and 100% of budget. Automatic dimming option reduces illuminance by 25% when 90% reached. Monthly conservation reports auto-generated. Reset budgets annually with new fiscal year.
