This document discusses architectural lighting controls in building automation systems. It covers topics like visual lighting parameters, case examples of lighting control in different modes, common lighting control functions, challenges around tuning and energy conservation, human-machine interfaces for controls, and methods for testing interfaces. The conclusions call for lighting design to have a more prominent role in projects, better understanding user needs, and more emphasis on long-term system maintenance beyond initial commissioning.

3. Motivation

4. Architectural Lighting

5. “Architectural Lighting is an act of crafting space – exterior and interior – with
light. This is illumination done in concert with architecture.
Architectural lighting is also meant to last for a substantial period of time
unlike, for example, theatrical lighting, which is created for a specific
performance and exists only for the duration of its run.”
Elizabeth Donoff, 2015

29. Solutions
1) Tuning is a mandatory function in the maintenance of advanced lighting
system. Whatever the control system is, such capacity should not be left to
commissioning tools (ETS5, Digidim Toolbox) only.

30. Solutions
1) Tuning is a mandatory function in the maintenance of advanced lighting
system. Whatever the control system is, such capacity should not be left to
commissioning tools (ETS5, Digidim Toolbox) only.
2) Interfaces should always be tested before commissioning.

31. Solutions

system. Whatever the control system is, such capacity should not be left to
commissioning tools (ETS5, Digidim Toolbox) only.
2) Interfaces should always be tested before commissioning.
3) Lighting project team requires a wide variety of skills: architecture, visual
design, electrical, automation, IT, networks…the commissioning inspector
should also have wide experience on different areas.

32. Conclusions

33. Conclusions
1) Lighting design is still often on a sidetrack on major projects

34. Conclusions
1) Lighting design is still often on a sidetrack on major projects
2) Contractors hope they would be more aware of the needs of actual users:
information is lost during the planning process

35. Conclusions
1) Lighting design is still often on a sidetrack on major projects
2) Contractors hope they would be more aware of the needs of actual users:
information is lost during the planning process
3) More emphasis should be put on system maintenance as addition to
commissioning: i.e. how do we tune the lighting levels when light output is
degraded?
