SITE’s Led Relamping for Carlsberg: a step forward to reduce CO2 emissions

SITE has carried out a relamping project in the production plant of Birrificio Angelo Poretti, installing Vivila LED solutions tailored to the client’s needs. The search for the perfect balance between respect for the company’s history and the sustainability goals of the Carlsberg Group enabled SITE to engineer the right LED solutions for the plant’s indoor and outdoor illumination systems from a lighting, optical, electrical and mechanical point of view. Thanks to this intervention, today Carlsberg is one of the first companies in Italy to have adopted LED technology.


The Carlsberg plant in Induno Olona, situated in the province of Varese, is one of the oldest and most impressive breweries in Italy. Built in 1876 by Varese-based entrepreneur Angelo Poretti, the production site is one of its kind because it perfectly combines history and innovation, marrying the building’s Art Nouveau architecture with the technologies used inside, which aim to respect the environment and use energy efficiently. Carlsberg has always paid great attention to the issue of sustainability and for years has been pursuing its “Together Towards ZERO” programme, which sets out to reduce CO2 emissions to zero. A goal that can be achieved thanks to relamping by SITE, in which Carlsberg has decided to invest in order to reduce energy consumption and cut CO2 emissions from the lighting systems inside the Angelo Poretti plant.


Carlsberg’s need to safeguard the uniqueness and the history of the plant posed SITE with two major challenges:

  • To develop LED systems capable of improving lighting in the indoor production areas (in accordance with the UNI EN 12464-1 standard) while at the same time guaranteeing energy savings and enhancing the building’s particular architectural features through the colour temperature of the light emitted by the lamps;
  • Comply with the strict regulations implemented in 2011 by the Lombardy Regional Authority on light pollution, in order to provide the new parking area with the right lighting. The proximity of the Induno Olona plant to the site of the “G.Schiapparelli” Astronomical Observatory has led to greater attention being paid to compliance with these regulations. The Observatory is in fact an internationally important site for the study of astronomical and climatic phenomena: in order to allow its activities to run smoothly, it was necessary to avoid any disturbing source of light.


To meet Carlsberg’s requirements, Vivila LED products were installed as lighting solutions both inside (in the production and storage area) and outside the plant (in the parking areas). In order to enhance the historical and architectural features of the Angelo Poretti Brewery, the brightness of the interiors was increased and a harmonious light colour was used, all in compliance with the lighting standards and requirements to be met by the production areas. The LED technologies installed inside the factory were as follows:

  • 1,500 mm long LED tubes of 23.5W and 2,800K;
  • High bay COB 180W 2800K;
  • High bay COB 160W 2800K.

Outside, in the new parking area, it was necessary to develop a lighting system in full compliance with the Lombardy Regional Authority regulations on light pollution, also taking into account the proximity of the “G. Schiapparelli” Astronomical Observatory. To meet these requirements, the solutions engineered and installed by SITE were:

  • 56W 4000K modular Street Lights;
  • 112W 4000K modular Street Lights.


Thanks to SITE’s relamping, the Induno Olona plant recorded the following annual results:

  • 66% reduction in energy consumption.
  • 84% reduction in CO2 emissions on traditional lighting systems, equivalent to 195.92 Kg of CO2 eq
  • Reduced maintenance costs thanks to the longer life of the devices installed, about 50,000 h
  • Reduction of heat released into the environment and of polluting substances in the case of lamp disposal
  • Increased lighting performance and more uniform, comfortable floor lighting in the production and storage areas.
