Protecting the Environment

With Reverberi Enetec, taking care of the environment means doing “a good bargain”

Working in defense of the environment has been a natural choice from the very beginning of Reverberi Enetec activity. Operating in accordance with the principle of providing “just as much as necessary light”, when and where it is required, means optimizing lighting energy costs, cutting greenhouse gas emissions, putting a stop to atmospheric light pollution: installing our light controllers means making as well an environmental friendly investment. Respecting the nature has never been so advantageous!

Paris Agreement COP 21: winning the challenge.

Almost 200 governments on December 13th 2015 signed an agreement to keep under 1,5° C the increase of earth temperature.
Among the tools identifi ed to achieve said objectives, the reduction of energy consumption in the public / industrial / residential and services sectors is of outstanding importance.
As a matter of fact, lighting is a significant share of electrical power expenditure in that energy may be saved by adopting energy- efficient lighting systems while improving the quality of visual conditions, thus contributing to effectively honour the commitments undertaken.

 

GreenLight Programme: solution is within reach.

GreenLight is a voluntary European Programme open to all those public and private electricity consumers that commit themselves to improve the performances and quality of their own lighting systems by installing energy-efficient lighting technologies in their facilities. As a GreenLight Endorser, Reverberi Enetec actively contributes to spreading the philosophy of the Programme and achieving the objectives thereof through tailor-made initiatives.
If you intend to join the Programme and get more in-depth acquainted with the advantages offered, look up in the European Commission web site.

The light pollution phenomenon

The brightness of the sky comes from the light diffused by the moon and the stars.
Said natural element is increased by the light produced by human activities, diffused skywards and refl ected by the molecules, gas particles and drops of dispersed gases that make up the terrestrial atmosphere. The luminous halo surrounding towns and urban conglomerations is the effect we can observe when travelling by air or even simply looking at the sky, which always returns a little bright image to our eyes.

The UNESCO Convention held in Paris in 1992 focused on the damage caused by an excessive skywards diffusion of luminous flux. This was the reason that pushed UNESCO to declare that starry sky is an heritage of the mankind, and as such must be protected especially to the benefi t of future generations, for whom the “light pollution” phenomenon not only represents a serious problem from the astronomical viewpoint, but should rather come into a wide-ranging context of environmental protection.

Negative impact of the light pollution

The biological rhythm of animals, trees and men strictly depends on the alternation of night and day that governs either the sleeping and waking time and the phases of chlorophylls’ photosynthesis.
Some 40 years ago, the sky was less bright than nowadays. Today, night sky is luminous, colorful, and we can hardly manage to see the weakest stars in our towns and in their outskirts. By now, nebulosity like the Milky Way or the tail of a comet are practically invisible. More than three quarters of people cannot enjoy the “true night” effect, because of the excessive lighting of the sky.
All this goes to the detriment of the nocturnal landscape and of the astronomical research. A starry sky is among the most beautiful heritages made available to mankind, and it is our moral obligation to preserve it to the best.
The fauna and fl ora as well are threatened by light pollution: particularly during birds seasonal migrations, the defi nite courses in which stars represent a steady reference point may undergo harmful variations because of the excessive halo that surrounds the towns. The hunting, feeding and breeding functions of numerous animal species, too, may suffer the effects of such a phenomenon.

How to fight light pollution

A good 20-30% of public lighting, including either the portion reflected by the soil and the buildings and that resulting from the incorrect positioning or choice of luminaires is directed up towards the sky. This dispersed flux is directly proportional to the light flux of installations: that means, a 50% decrease in the flux of the installation actually corresponds to a 50% decrease in the flux dispersed in the atmosphere. The harmful effects of the atmospheric light pollution can therefore be considerably restrained by adopting a lighting control system. The results we obtain by adopting said technologies will be by far the most effective compared to other possible measures.
Most of the laws enforce that:”...All the lighting installations must be provided with devices capable of reducing energy consumptions by a minimum 30% to maximum 50% rate...”.
