*인터렉티브 어반 등대 [ LDC ] SILO468_INTERACTIVE LIGHT ART FOR URBAN REDEVELOPMENT

새로운 장소성을 제시한다. 필란드 헬싱키, 바다에 면한 작은 마을에 버려진 사일로는

이지역의 자연적인 빛과 바람 그리고 움직임을 재구성하는 거대한 빛의 파빌리온으로

리뉴얼된다. 백색의 실린더에 펀칭된 2012개의 홀과 내부에 설치된 1280개의

LED조명은 인공지능에 의해 5분 간격으로 수집된 이지역의 바람속도, 방향, 온도, 시계성, 적설량 등을

이지역의 11,000명의 움직임을 포함하여 빛의 패턴으로 비쥬얼라이징 한다.

이러한 빛의 패턴은 밤 12시를 기점으로 1시간 가량 깊은 레드빛으로

바뀌며 마지막 페리가 떠나는 2시 30분 이후로 점멸한다.

주야간 다른 얼굴의 파빌리온은 2012개의 홀을 통한 빛과 그림자로

빛의 움직임을 나타내는 주간과 1280개의 LED조명으로

빛의 파장, 패턴을 만들어 내는 야간으로 크게 구성된다.

이제 사일로는 한정적인 대지를 벗어나 주위로 확장된 바운더리를

형성하며 주위를 하나로 묶는 랜드마크가 된다.

Disused oil silo has been converted into mesmerizing light art piece and a public space with the aid of swarm intelligence and interactive lighting.

The project is a conversion of oil silo into light art piece and a public space designed by Madrid based Lighting Design Collective (LDC).

It sits by the sea facing central Helsinki, Finland. Prevailing winds well known to residents are strongly present. The natural light, wind and the movement of light on the water formed the principles for the lighting concept. Walls are perforated with 2012 holes referring to the Helsinki World Design Capital 2012 year.

The lighting signifies the start of a major urban redevelopment for the City of Helsinki. It functions to draw focus to unknown district and creates a landmark and a marketing device for the City. Maybe most importantly through the use of natural and artificial light it created a unique civic space for the citizens to use. Furthermore, it set a precedent for a new district for 11000 people to become the “district of light”. During the first years the silo is mainly viewed from distance when the area starts to get build. 1280 LED domes in 2700K white are fitted inside the silo behind the cut-outs and visible from several kilometres away.

LDC developed a bespoke software using swarm intelligence and nature simulating algorithms that refresh responding to parameters such as wind speed, direction, temperature, clear night and snow. System dials out every 5 minutes for new data. The patterns are fluid, natural in feel and never repeat. They are slow but speed up in relation to the wind speeds creating constantly changing mural of light. At midnight the exterior turns deep red for 1 hour. The colour refers to the former use of the silo as a container of energy. At 02:30 when the last ferry goes past to Suomenlinna lights go off.

The interior gains importance as the area gets populated. Inside is painted deep red. Daylight seeps through the pattern derived from original rust patterns on the walls. North facing wall has no perforations. 450 steel mirrors moved by winds are fitted behind the holes. With sunlight the silo appears to glimmer and sparkle like surface of water.The warm white LED grid reflects light indirectly via the red walls into the space. The moving patterns read as halos racing across the walls. The Silo is a civic space for the citizens of Helsinki. Floor was added and rigging infrastructure, power, water and emergency & cleaning lighting. Light intervention has created a new space for people.

During normal use the installation uses about 2kw of power, which is approximately 2W per square meter. The software creates a particle system that combines motion behaviors from birds, insects, an fishes to create organic and non repetitive animations for the lighting system, in a 128 x 10 LED grid. This animations are being generated using current data from the local weather, specially wind speed and direction, to create a vast and unpredictable array of light movements that give the viewer a visual representation of the weather sensations in the city. The control application was developed in OpenFrameworks, an open source c++ toolkit for creative coding, an runs in an e:cue Lighting Control Engine mx server.
