LED technology renews Perini S.p.A.’s industrial buildings. Measurable results in terms of energy efficiency, sustainability and job quality for workers

The lighting design project started up at the end of 2015 and brought to term in collaboration with Philips Lighting, involved the 5 industrial workshop buildings of the Lucca plant. The company’s requalification work involved renewal and modernization aimed at yielding noticeable energy and economic savings and at improving the work environment through the use of more advanced high-bay lighting technologies respectful of the environment.
Philips, chosen as technological partner for the project, supplied a solution capable of distributing light in uniform fashion and at the same time differentiating it according to the needs of the various areas, guaranteeing a wide array of light combinations. The outcome was made possible thanks to the addition of over 600 Gentle Space luminaires – LED projectors that expertly combine functionality and design while also offering optimal performance in terms of energy savings.
All is governed by a control system for the projectors that detects natural light and indicates how many projectors must be activated and in which areas in order to meet the demand for lighting. The result is to optimally mix LED light and natural light coming from the windows so that lighting in the workplace area is constant. The LED technology chosen replaces the existing metal-halide discharge lamps – a solution difficult to modulate because it cannot be dimmed and only features the on-off functions throughout the entire surface, meaning high energy expenditure.

Benefits

The intervention has brought important energy and economic benefits to Perini S.p.A. and has also allowed to enhance the quality and comfort of the workplace. Indeed, this replacement and the introduction of LED solutions has yielded an energy savings in excess of 60% and an expected 4-year ROI. Furthermore, based on the measurements performed in just over a semester of activity (October 2015 – May 2016), the new system has drastically reduced its environmental impact, preventing 278 tons of CO2 from being released into the atmosphere. This is equivalent to eliminating 588 vehicles from the road, 88.3 tons of waste in landfills, 135 tons of coal burned, and to saving 106 hectares of forests.
Ultimately, the people working in these buildings benefit, too. Lighting has improved inside the work environment, making the area more comfortable and suitable to carry out daily tasks.
