According to industry sources, the revised Energy Performance of Buildings Directive (EPBD) introduces a clear and far-reaching requirement: all new commercial buildings in the European Union must be equipped with automatic lighting control systems and building automation systems (BAS). This provision transforms smart lighting from an optional value-added feature into a mandatory component of all new commercial construction projects.
Under the new framework, lighting products are no longer regarded as standalone luminaires. Instead, they must be designed with built-in connectivity and interoperability, enabling seamless integration into a building's intelligent management system. This allows functions such as occupancy-based lighting control, daylight harvesting, energy monitoring, and intelligent energy management.
From a technical perspective, manufacturers are required to ensure compatibility with standardized communication technologies, particularly the EU's Smart Readiness Indicator (SRI) framework and globally recognized communication protocols such as Matter. On the driver side, products must comply with the mandatory D4i Gen 2 requirements. In addition to supporting DALI dimming, LED drivers must meet the energy metering and diagnostic capabilities specified in DALI Parts 250–253. Furthermore, drivers must be installed independently, utilize pluggable terminal connections, and must not share the same thermal path as the LED module.
By making automatic lighting control a mandatory requirement rather than an optional enhancement, the EPBD fundamentally changes the role of lighting products. Luminaires are no longer independent devices that can simply be installed or replaced—they are now required to function as integral endpoints within a building automation ecosystem.
The regulatory rationale is straightforward. Buildings account for approximately 40% of the European Union's total energy consumption, with lighting representing one of the largest electricity loads. Through mandatory connectivity and system-level control, sensors can optimize lighting operation based on occupancy, daylight availability, and real-time demand, helping new buildings approach nearly zero-energy building (NZEB) performance standards.
As a result, selling a 'smart bulb' that cannot communicate with a building management system no longer satisfies the legal requirements for overall building energy performance. In essence, lighting products are being redefined—from standalone industrial products to core components of a building's energy management system. Regulatory focus is shifting beyond the product itself to its overall contribution to energy efficiency within real-world building applications.
The core principle of the EPBD is not to prohibit standalone lighting products, but to require that luminaires possess system connectivity and interoperability. For Chinese manufacturers, this means redefining products from being driven by lighting performance specifications to being defined by data interface capabilities—from selling hardware to providing fully integrated, intelligent data nodes.
