Pully relies on energy-efficient, environmentally friendly and climate-neutral lighting
Pully has been committed to a sustainable energy policy for years. In 2017, they were awarded the Energy City Label for this, thanks in particular to the efficient renovation of street lighting. In this interview, Amandine Massart (engineer at SI Pully) tells us what measures are being implemented to reduce energy consumption and how Pully is targeting light pollution.
In conversation with
Amandine Massart, Engineer at SI Pully
What has changed in the field of lighting and environmental awareness in recent years?
The introduction of LEDs has been a real revolution in the field of public lighting. They make it possible to illuminate better while consuming much less energy. By "better," it is meant that the luminous flux can be better directed and channeled, minimizing light pollution.
With LEDs, various systems to reduce over-lighting and light pollution have gradually come onto the market, such as night setback and motion sensors. These systems are increasingly modular to meet the needs of any situation.
With the rise of these new technologies, standards have also adapted, making it possible to use light differently at different times of the night.
Increasingly, the issue of light pollution is gaining importance. Numerous studies demonstrate the harmful effects of light on health and biodiversity. The development of new lighting systems aims, on the one hand, to limit energy consumption, but more importantly, to reduce light pollution in the environment.
How do you deal with the issue of "climate protection", especially in the field of lighting?
Pully has been committed to an active energy policy for many years and was rewarded in 2017 with the award of the Energy City label, thanks in particular to its public lighting, which was classified as "exemplary" by the Swiss Agency for Energy Efficiency (SAFE)
Between 2013 and 2015, the "MAREP" project (Accelerated Measures to Reduce the Consumption of Public Lighting) replaced approximately 30% of the city's lighting with luminaires using the latest technology, reducing electricity consumption by more than 20%.
Since then, the improvements have continued every year. Gradually, energy-intensive lighting fixtures are being replaced with warm-white LED fixtures that are directed downward only and whose luminous intensity is systematically reduced at night. Recently, residential areas have been equipped with motion sensors for dynamic lighting when the lighting infrastructure is renewed.
For what reasons did you choose climate-neutral Luma luminaires?
As part of its energy policy, Pully is keen to implement measures that can contribute directly or indirectly to reducing energy consumption.
