Lighting in industry and manufacturing: what the SRI measures
For lighting, the SRI does not measure the lamp but the control: does the light switch off when nobody is there, and does it dim with daylight. This is often the cheapest domain to score points in.
In short
- 1This page shows how the Smart Readiness Indicator (SRI) assesses the Lighting domain in industrial and production buildings.
- 2Lighting carries 2 of the 3 weighting points for this building type, and is often the most cost-effective domain for score improvement.
- 3The SRI examines only the building and its systems in industrial facilities, not the production process itself.
Weight of this domain for this building type
Which services count
| Service | Lowest level | Highest level | Advice |
|---|---|---|---|
| Occupancy control for indoor lighting L-1a · A · 4 levels | Manual on/off switch | Automatic detection (manual on / dimmed or auto off) | level 2 or higher |
| Control artificial lighting power based on daylight levels L-2 · 5 levels | Manual (central) | Automatic dimming including scene-based light control (during time intervals, dynamic and adapted lighting scenes are set, for example, in terms of illuminance level, different correlated colour temperature (CCT) and the possibility to change the light distribution within the space according to e.g. design, human needs, visual tasks) | – |
Worked example
If everything in this domain is at level 0, the domain contributes nothing. At the highest level for all services, the indicative total score for this building type rises by about 5 percentage points (from 33 to 38 percent, with all other domains at level 1).
What does the SRI measure in lighting for an industrial building?
The Smart Readiness Indicator assesses the Lighting domain not by lamp type, but by the control system around it. Does the light switch off automatically when no one is present, and does artificial light adapt to incoming daylight?
In industry and production, this domain applies to office spaces, warehouses, corridors and other building areas. The production process itself, including any process lighting on the work floor, falls outside the assessment.
Which two services count?
The methodology distinguishes two smart-ready services within this domain. The first is occupancy control for indoor lighting (L-1a). This service has four levels, from a manual on/off switch (level 0) to automatic detection where the light switches off automatically when a space is empty (level 3).
The second service is artificial light power regulation based on daylight level (L-2). Levels range from manual operation per room to automatic dimming with scene-controlled lighting, where brightness and colour temperature adjust automatically to time or task.
For industrial buildings, the step from level 0 or 1 to level 2 is often enough for a noticeable score improvement.
Why does this domain carry such weight for industry?
For this building type, Lighting accounts for 2 of the 3 weighting points in the overall calculation. This is relatively high compared with other domains such as heating or energy management, which are often already well-regulated for the production process in industry.
Large halls and warehouses typically have extensive lighting area and relatively straightforward control technology. An upgrade from manual switches to automatic occupancy detection is technically limited in scope and can significantly raise the score in this domain.
What does this mean for the rest of the SRI score?
Because energy management in industrial buildings often exists for the production process, remaining room for improvement frequently lies in simpler domains such as lighting. This makes the domain a logical starting point in an initial SRI assessment.
A higher Lighting score does not automatically offset a low score elsewhere, but does contribute to a better position within the seven classes into which the final result is divided.
What this means for you
- Owner
- As owner of an industrial or production building, it is worth starting by examining lighting control in offices, corridors and warehouses, because this domain carries significant weight and is relatively inexpensive to improve. Automatic occupancy detection and daylight-dependent dimming often deliver immediate energy savings alongside a better SRI score.
- Tenant
- As tenant or user, you will notice a well-regulated lighting domain mainly in convenience: light comes on automatically upon entry and dims with daylight, without you needing to operate switches yourself. This contributes to a comfortable work environment without unnecessary energy consumption.
- Advisor
- Pay attention to the distinction between the building and the production process during assessment, as only lighting in building-related spaces counts towards the SRI. Also check whether occupancy control and daylight control have been assessed separately, as both services contribute individually to the score of this domain.
