How was lighting integrated into the park?
Paulina Villalobos: The main task was to respect the landscape, illuminating only the routes and areas frequented by people, leaving the vegetation to follow the pattern of natural light.
How have you managed to respect the need for energy efficiency?
Paulina Villalobos: We decided to give most of the routes flush lighting finishes, lowering the luminous flux by up to 100 times relative to overhead lighting. In addition, the luminaires installed for the large areas work from dusk until the park closes, and are only activated when they are needed.
When the luminaires were originally specified for the project, they were the most efficient on the market at the time (80-90 Lm/W). Today, after two years, we find that the exterior energy efficiency is surprisingly even higher.
How has the water/river influenced the project?
Paulina Villalobos: The River was the origin of the city of Santiago. Its riverbanks were once used for the cultivation of native food species, and they provided sustenance to the city. The project takes into account the value of the surrounding areas, recovering the riverside for a large-scale urban park that is strategically located. The water regains its historic role and is part of the concept that defines the lighting criteria for this new park.
What is the function of the image projections (gobo) in the area?
Paulina Villalobos: There are two large esplanades at each end of the lagoon, and the idea was to generate on these large arid surfaces a feeling of being in a fluvial park, and the sense of walking on the surface of water.
How did the users of the park react to this new concept?
Paulina Villalobos: In a very playful way. Children can swim and play there. Both light and shadow play an important role, as the children can see the light projected on themselves and in turn the reflected shadows.
What technology is used for the lighting?
Paulina Villalobos: Everything uses LED lighting with a color temperature of 3,000 K, except in the marathon route, where the lamps are at 4,000 K.
What products or systems were installed?
Paulina Villalobos: The use of gobo projectors and traditional luminaires. In this case, there is no control system because, when the park closes, the whole lighting system shuts down.
How were the footbridges illuminated?
Paulina Villalobos: The illumination for the footbridges is under the balustrades, illuminating the route with a flush finish.
