PROJECT / OLIMPIYSKIY STADIUM, KIEV, UKRAINE
Originally built in 1923, the Olimpiyskiy Stadium in the Ukrainian capital of Kiev underwent an extensive program of renova- tions in the lead up to Euro 2012, preparing it to host more than 66,000 football fans for each of its allocated matches. Fol- lowing plans drawn up by GMP Architects, the stadium’s lower tier was redesigned, press and VIP boxes added and a new roof installed to cover the seating areas. Illumination of the stadium’s exterior and internal public spaces was overseen by Con- ceptlicht. The practice applied its philoso- phy of considered lighting to the project, allowing the identity of the structure to be revealed.
“Creating lightness in the darkness entails a material effort and costs energy,” explains Conceptlicht Principal Helmut Angerer. “For this reason, what is illuminated at night must be significant and justify the effort – regardless of what the lightness is intended for. If one looks from this perspec- tive at the city at night, questions arise: Why is the facade next to the streetlight illuminated? Why, in contrast, does the distinguished oriel next to it remain in the dark? The picture painted by cities at night seems to be characterised by a distribution of light densities that points more toward the presence of inadequate lighting fixtures than to the urban space and its meanings. The undifferentiated illumination is thereby unavoidably connected with a loss of au- thenticity.”
He continues: “A critical view reveals that architecture is degraded to a monoculture by series lighting, because uniform light pic- tures arise. By necessity, when standard ar- chitectural lighting techniques are applied, lighting elements cannot provide striking light, and simply yield standard effects. The prerequisites for a meaningful perceived picture are thereby largely lost. This can be prevented by conceiving and treating the room as a whole, and by having the light in the foreground, not the lamp. “Sophisticated lighting design strives to maintain or to create clarity. The lighting density hierarchy respects and strengthens meanings. The result should leave a self-ev- ident and therefore powerful impression.” Applying these principles to the Olimpiyskiy Stadium, the Conceptlicht team set about creating a scheme that would deliver a clear impression of the building as a whole. Their solution uses a palette of Schréder Cubo and LEDbeam luminaires throughout.
SEATING BOWL AND FAÇADE SCREEN From outside, the venue’s structure is clearly visible: the ridged underside of the stadium’s upper tier of seating is seen
through a loose screen of horizontal bars that make up the outer wall. This screen runs between the parade of columns that support the new roof structure. The shell-like shape of the seating’s under- side was identified as a core element of the stadium and was therefore given full cover- age lighting. Dimmable fluorescent strips are placed along the arms that support the seating, running perpendicular to the ridg- es. The radiation characteristics of these strips are arranged in such a way that they stop parallel to the seating shell’s surface and are therefore not directly visible from below, thus avoiding glare. The linearity of the source gives a uniform illumination of the ribbed shell surface ensuring no hard shadows are formed.
The shell scheme is completed with a line of 600mm dimmable linear LED fixtures. These are used as cove lighting around the top edge of the bowl.
Above The main columns of the facade wall are left without direct lighting to allow the form of the seating bowl within to remain clearly visible. For the steps outside, Conceptlicht’s design specified handrails with concealed LEDs to avoid glare although ultimately Golden Dragon Plus LEDs with a beam angle of 170° from Osram Opto Semiconductors were installed.
