Architectural & Façade Lighting.

The building and the grounds, after dark.

Façade graze, in-grade uplights, linear coves, water-feature lighting, drive and pathway detailing, tree uplights and perimeter flood — engineered, programmed and night-commissioned on one Rako control surface.

Landscape lighting scenes

  • Dawn: Pre-sunrise blue hour. The villa wakes up, façade lifts to 35%.
  • Dusk: Façade full. Pool warm. Tree canopy uplit. The building performs.
  • Soirée: Pool RGB. Tree magenta wash. Façade dimmed for intimacy.
  • Security: Cool 5000 K perimeter flood. Camera corners armed. Interior off.

/ The discipline, in detail

How we approach architectural & façade lighting.

Most façade lighting is afflicted by a single mistake: it lights the wall instead of the building. Real architectural lighting is composed shot by shot — grazing for texture, uplights for proportion, coves for layering, and dark zones held back deliberately so the lit zones can speak. The same composition discipline extends to the grounds: drive pathway, garden uplights, pool feature and perimeter flood are programmed as scenes that move through the day, not as switches the operator hunts for.

We work alongside lighting designers, or take on the LD role when the architect requires a single accountable hand from concept to commissioning. We commission on site, at night, with a colorimeter — and we re-aim, re-shim and re-balance against what the architecture is actually doing under the fixtures. Underneath, iGuzzini, Erco, Bega and Pharos specify the actual fixtures; Rako and MADRIX carry the control. Every project ships with a calendar of named scenes, a manual override panel for the operations team, and night-photography proof before handover.

On record

Every architectural & façade lighting engagement is documented end-to-end — design, programming, commissioning, calibration — and handed over with the files our successors would need if we were never to return.

/ Protocol stack

Facade circuits, addressed

Exterior architectural lighting follows the same addressable-control discipline as interior scenes — schedules, zones and dimming curves on one stack.

Lighting protocol stackA three-layer canonical lighting control architecture: BMS supervisor layer at the top, scene/keypad layer in the middle (proprietary protocols Rako, KNX, Lutron), an addressable bus layer connecting the scene controls to fittings (DALI-2 typically), and fittings at the bottom with addressable drivers and emergency self-test. The arrows show the direction of control telegrams; the gateway bridges proprietary scene protocols to DALI-2 at the fitting layer.Lighting stack · Hybrid scene + addressable fixtures01 · SupervisorBMS / FacilitiesHoneywell EBI · Siemens Desigo · BACnet/IP02 · Scene / KeypadRako KeypadLiving · Dinner · GoodnightKNX SwitchABB · Gira · SchneiderLutron HW QSXEngraved ArchitecturalTouch PanelWall · Mobile · Tablet03 · Bus / GatewayKNX TP BusTwisted-pair backboneDALI GatewayKNX → DALI bridge04 · FittingsDownlightDALI-2 driverPendantTunable whiteLinearArchitecturalWallwashRGBWEmergencySelf-test (Part 202)Each layer is loosely coupled — a failed keypad does not bring down the bus; a failed gateway does not bring down adjacent zones.

/ Where we deploy this

Active across 6 sectors.

Architectural & Façade Lighting is rarely a standalone brief — it sits inside a wider sector practice with its own codes, expectations and operating rhythm.

Architectural & Façade Lighting — getting the brief right.

Common mistakes to avoid

  • Lighting the wall instead of the building — fixture-first schemes with no composition intent read as floodlit, not lit.
  • Choosing fixtures without ingress and impact ratings honest to the exposure — monsoon rain, dust and insects retire under-specified fittings within a season.
  • Skipping night commissioning — aiming, shimming and balancing cannot be done from a render at noon.
  • No maintenance-access plan for in-grade and high-level fixtures, so failed fittings simply stay dark.
  • Designing the façade scheme apart from the perimeter-security lighting and CCTV plan, so the two fight each other after dark.

What to share before a quotation

  • Elevations and the site plan — the façades, grounds and features to be lit.
  • The architectural intent — what should read at night, and what should deliberately stay dark.
  • The exposure each fixture position faces — rain, dust, irrigation, vehicle areas.
  • Control expectations — scenes, schedules, event calendar — and the platform in use.
  • The power and containment provisions already in the civil and electrical design.

/ Frequently asked

Architectural & Façade Lighting — what buyers ask first.

Static or dynamic façade?

Choose a single static façade scene tuned to the architecture for most premium buildings; dynamic colour cycles only earn their place on civic and event-centred buildings, and quickly date a quieter project. We recommend dynamic only where the building's role earns it.

Why do landscape and façade jobs need night commissioning?

Because daylight cannot tell you what a façade graze looks like at 2700 K against textured stone, what a tree uplight does to a Frangipani canopy in monsoon humidity, or whether the pool RGB matches the cabana scene at 9 pm. Render walks do not catch any of that. We commission on site, at night, with a colorimeter — and we re-aim, re-shim and re-balance against what the architecture is actually doing under the fixtures.

Can the grounds integrate with the home automation system?

Yes — Rako landscape scenes share the same keypad layer as the interior on a single Wi-Bridge backbone, so the porte-cochère keypad calls 'Welcome' as one gesture that lifts the foyer cove and the drive pathway in the same instant. The integration is at the controller, not at the keypad — there is no second remote for the grounds.

What makes architectural facade lighting 'good' versus garish?

Restraint. The best facade lighting reveals the building's geometry — uplighting on stone walls, cove lighting in a soffit, water-feature lighting from below — without using colour-cycling RGB. We almost always specify warm-white (2200–3000K) static or single-channel tunable, never RGB chase patterns.

How much does facade lighting save on energy with daylight sensors?

Astronomical timers and lux sensors typically run facade lighting for 8–10 hours per day rather than 12–14. On a building with 5–8 kW of facade load, that's 8,000–12,000 kWh per year of recovered consumption. The control system pays back its cost on energy alone in 2–3 years.

How do you protect facade fixtures from monsoon?

All exterior fixtures are specified to IP66 minimum, with potted electronics and stainless or marine-grade aluminium housings. Drivers are mounted internally where possible, with conduits routed through the architecture rather than over its surface. We design for the coastal/humid environment our region experiences.

Can dynamic facade lighting be programmed for events?

Yes — we programme event scenes (Diwali warm tone, Republic Day tricolour, brand-event-specific palettes) into the controller, accessible via a single keypad press from reception or a tablet. The everyday default is restrained warm-white; the dynamic scenes are an option, not a constant.

Will facade lighting attract pests?

Cool-temperature LEDs (above 4000K) attract significantly more insects than warm-white (2700K and below). We default to 2700K or warmer for any facade-lighting scheme that is on continuously, which dramatically reduces the moth-and-mosquito magnet effect that cheap landscape lighting creates.
