Sistemi di Regolazione dell’Illuminazione alla luce dei nuovi CAM

The Italian Decree of June 23, 2022 has introduced important innovations regarding CAM for the sourcing of design services for building construction. The Decree, which went into effect last December 4th, also establishes the Minimum Environmental Criteria (in Italian “CAM – Criteri Minimi Ambientali”) that indoor lighting systems must meet. Specifically, Article 2.4.3 of the Decree requires that facilities must be equipped with lighting management systems capable of switching/off and dimming automatically. This should be done not only on an hourly basis, but also in accordance with any natural light phenomena. The management of such systems is based on:

  • Occupancy status of the areas

  • Existing average lighting level

  • Time of day

These requirements must be adhered to when designing buildings for both residential and non-residential use solely in common areas regulated by the Public Contract Code.

Minimum environmental requirements: a commitment to digital lighting control and automatic dimming

CAM are environmental and ecological requirements defined by the Ministry of Ecological Transition aimed at helping public administrations to rationalize consumption and procurement by providing guidance for identifying more environment-friendly design solutions, products or services. When it comes to indoor lighting, the adoption of management systems such as Duemmegi’s DALI-2 DUELUX System is a beneficial option. The use of these systems is considered in all building projects regulated by the Public Contracts Code, both in new construction and the renovation of existing buildings.

Specifically, in new building construction projects, including renovation work, CAM certification entails the design of lighting fixture bus systems. The minimum environmental requirements foresee the use of a smart lighting system that includes:

  • Dimmable lighting fixtures (e.g., equipped with DALI, DALI-2 drivers).
  • • Light/presence or light/motion bus sensors connected to a bus system equipped with appropriate DALI, DALI-2 gateways for automatic dimming.

A system for dimming the light intensity allows not only greater energy savings, but also the creation of an extremely comfortable and productive working or living environment.

Compliance with CAM has become a mandatory requirement for engineers. Duemmegi, with its 30 years of experience in the field of lighting automation, is the ideal partner you can rely on. Thanks to the DALI-2 certified DUELUX Bus System, our company can implement highly customizable solutions and meet the CAM requirements for automatic lighting control systems.

CAM lighting: why choosing a DALI system is the winning solution

DALI lighting management is the winning solution for a smart lighting system that complies with CAM and promotes energy savings and room comfort. Duemmegi’s DALI-2 DUELUX System enables the management of lighting for different rooms, individual lights or lighting groups, with ease and convenience. Based on the international DALI-2 standard, it allows engineers and installers to take advantage of all the benefits of the new protocol for professional, efficient lighting automation without costly installation work.

Why rely on DALI? DALI (Digital Addressable Lighting Interface) is a non-proprietary international digital interface standard compliant with IEC EN62386. It is a protocol created specifically for lighting and allows lighting fixtures to be controlled digitally. Starting in 2014, DALI-2 has evolved to allow the creation of a simplified system architecture, but with added functionality and greatly reduced installation costs.

Thanks to the DALI-2 standard, on a single 2-wire bus cable it is possible to connect:

  • Lighting fixtures with DALI-2 or DALI drivers
  • DALI-2 controller
  • DALI-2 input modules for connecting pushbuttons and switches
  • DALI-2 wireless receiver modules for connecting Enocean battery-free wireless keypads
  • Light and presence sensors, DALI-2 light and motion sensors (DALI-2 sensors, DALI light sensors)
  • DALI-2 actuator modules with 2 relays
  • Lamps (with DALI dimmer control)
  • DALI-2 actuator modules with 2 relays for motor control.

Lighting control with DALI means managing the lighting of different rooms with ease and convenience, allowing the adjustment of light intensity for comfortable indoor spaces with tangible results in terms of energy savings.
