What constraints apply to laser projection on ancient town building facades?
Direct answerHeritage facades need controlled power and illumination duration to avoid heat damage, non-destructive concealed installation, and content that matches the local historical style.
Core Constraints on Heritage Surfaces
- Control laser power and daily illumination duration to prevent heat-related facade damage
- Conceal all equipment without drilling, fixings or changes to the original structure
- Design show content to match the local historical and architectural context
- Complete a heritage-protection assessment before power, projection angle and runtime are fixed
- Plan maintenance that does not require repeated access to protected surfaces
What the Assessment Should Cover
- Surface material and its sensitivity to heat and light
- Permitted installation methods and fixing points agreed with the heritage authority
- Maximum daily exposure time and approved show schedule
- Documentation required before installation is approved
On heritage projects the assessment usually defines the technical limits, so engage the heritage authority before the show design is finalised.
