Lighting design in large projects: where functionality and architecture meet

Why large lighting projects fail without a lighting design

Large projects involve multiple zones (workspaces, circulation areas, reception, meeting rooms, multifunctional areas…), often combined with tight deadlines and a high level of finishing. In this context, a lighting design must:

1. Be functionally correct (lighting levels, uniformity, glare control, proper accents)
2. Be architecturally coherent (lines, rhythm, integration into ceilings and walls)
3. Remain logical in maintenance (access for servicing, replaceability, consistent choices)
4. Operate efficiently (energy use, controls, zoning)

Comfort is also a design criterion

A professional lighting design starts from usage. Which spaces require precision and focus? Where is orientation crucial? Where is atmosphere the priority? By clearly defining functions first, you avoid common issues in large projects: shadows on work areas, disturbing reflections, or “cold” corridors and stairwells.

Controls also play a role: dimming, zoning, daylight regulation… These help tailor lighting to users. In larger buildings, this becomes a key lever for a system that adapts intelligently. Well-thought-out zoning also helps reduce energy consumption without compromising comfort.

Architecture: light as part of the bigger picture

Architectural lighting works best when it is integrated into the building design. Think of light lines aligned with ceiling modules, lighting compositions forming a unique pattern, or profiles that follow the rhythm of the building. This creates visual calm: ceilings appear cleaner, spaces are connected, and you avoid a “patchwork” of fixtures without coherence.

That is why Multiline works with linear systems such as Rekta 30: ideal for creating continuous light lines that remain visually consistent while technically accommodating different functions (for example, variations in light distribution per zone). In projects where integration into climate ceilings is important, Rekta 65 EKP can be a strong solution. This profile is specifically developed for climate ceiling integration, taking into account two critical aspects in large projects: ease of installation and maintenance efficiency.

Three common pitfalls in large projects

In large projects, we mainly see three recurring areas of tension:

1.Beautiful concept, difficult execution

If details (dimensions, mounting, connections) are worked out too late, last-minute adjustments can undermine a strong design. A good lighting design considers execution from the start: how it will be installed, how components connect, and what tolerances are realistic on site?

2.Tight integration, difficult maintenance

Architectural integration is only successful if maintenance does not require dismantling. It is essential to choose service-friendly solutions: accessible components, logical construction, and long-term availability of parts.

3.Low upfront cost, high operational cost

A solution that appears cheaper initially can become more expensive due to energy use, maintenance time, and lack of flexibility. Optimizing only for purchase price often leads to higher costs later through interventions, replacements, or adjustments when layouts change.

Start with a well-considered lighting design

In large projects, lighting design connects technology and architecture. When approached thoughtfully from the start, it results in a building that not only looks good at completion but remains comfortable, efficient, and flexible in use. Multiline supports this process with a tailored approach for each project.
