International. The combination of natural light with artificial, zoning, time control or presence detection systems, could save energy consumption by up to 80% in public lighting.
This concludes a study by the Spanish Association of Lighting Manufacturers, Afalum. The president of the Association, Rafael Barón, explained that the change in the public lighting system is a necessity.
"With an average of 3%, the replacement rate in public lighting is very low. It means that there is a change every 25 years, while in the tertiary sector, among which are commercial premises and offices, this period is around 15 years, "he said.
He gave as an example the case of Spain, a country of the European Union that stands out for being the one with the highest energy consumption because part of its public lighting has mercury vapor lamps, a technology created in 1940.
If this system is changed, the Spanish government could save about 100 million euros a year from the 450 million euros it spends annually on lighting. This would be achieved with the implementation of systems designed specifically for each space.
In addition, with the use of LED lighting, of which the Afalum study assures that by 2020 they will concentrate 60% of the market.
