LOW CARBON BUILDINGS
DALI-2: the foundation of smarter, more sustainable buildings
T
The automated lighting control industry continues to evolve at a rapid pace. As businesses strive to cut energy costs and reduce operating outlays, whilst meeting sustainability targets, demand for tailor- made lighting control systems with after sale support has never been higher. James Hart from zencontrol explains the latest developments
he industry has shifted from traditional lighting control to data- driven, intelligent systems. Our strategy from day one has been to make advanced technology simple, reliable, and accessible for
every project.
Raising the standard for lighting control
The past decade has seen major technological changes, from wireless integration to advanced analytics. Customers now expect seamless integration with building management systems, higher energy efficiency and detailed reporting. Modern buildings don’t just need lights that turn on and off – they need systems that communicate, self-test, and adapt to real-time usage.
The shift from DALI to DALI-2
A major transformation in the industry has been the transition from the original DALI – the lighting control standard for commercial buildings, offices, schools, hospitals and increasingly in smart buildings – to DALI-2, which offers clearer standardisation, improved testing and enhanced device interoperability. DALI-2 provides consistency and confidence. It ensures sensors, switches, and control gear work together, regardless of manufacturer. That reliability wasn’t guaranteed with early DALI. zencontrol has played a key role in this shift by offering one of the industry’s most complete ranges of DALI-2 certified devices,
including application controllers and advanced monitoring tools.
Sustainability and energy cost savings
DALI-2 systems enable businesses to significantly reduce energy consumption through features such as occupancy-based control, daylight harvesting, scheduled dimming, and real-time performance monitoring.
Lighting is one of the largest energy loads in commercial buildings. With a properly designed DALI-2 system, organisations can cut lighting energy use by up to 50–70%, while also extending luminaire lifespan and reducing maintenance costs. By providing detailed energy reporting and system insights, zencontrol’s cloud-connected platforms also help businesses evidence carbon reductions, support ESG reporting, and make informed decisions that align operational efficiency with long-term sustainability targets.
Future vision
We’re moving towards smarter buildings that respond dynamically to people and environments. DALI-2 is the foundation, but the next leap comes from connecting lighting, emergency systems, and IoT sensors into a single intelligent ecosystem.
