Architecture in Light

The upper pavilion of the Neue Nationalgalerie is a temple of absolute structural purity: an 8.4-meter-high clear glass perimeter enclosed under a monumental 1,200-ton steel roof grid suspended on only eight cruciform steel columns. There are no interior weight-bearing walls—only two free-standing Roman travertine service cores. Any lighting intervention had to honor the strict 3.6-meter square modular ceiling cassette grid established by Mies van der Rohe.

The primary challenge was two-fold: First, from the exterior streetscape at night, the glass pavilion must remain an unobstructed lantern of pure spatial volume. Conventional luminaires produced catastrophic mirror reflections on the 8.4m clear glass façade, blinding viewers outside and destroying the visual connection to Berlin’s Kulturforum. Second, the 42-meter travertine core walls required absolute vertical illuminance uniformity (ratio < 1:2) to display large-format modern canvases without scalloping or hot spots on the upper frieze.

Lichtvision conceived a strategy of "Luminous Absence": light without visible sources. By embedding asymmetric linear wallwashers into the exact recessed reveal seams of the 3.6m modular roof cassettes, the light origin vanishes entirely from normal observer sightlines. The travertine core walls become the primary luminous field of the pavilion, bathing the interior in soft secondary reflected light while the ceiling remains quiet, dark, and monumental.

Deployed KINETIC G-WALL asymmetric micro-prismatic optics offset at exactly 1,200mm from the vertical stone face. The compound PMMA micro-prism redirects 82% of luminous flux downward at a 25° forward cant, ensuring the uppermost 150mm of the wall receives identical illuminance to eye level. To highlight free-standing Giacometti bronze figures, STYLOS O-12 darklight pinholes were installed at grid intersection nodes, utilizing high-purity quartz TIR lenses with a 55° physical cutoff cone. Even when energized to 1,200 lumens, the aperture luminance appears completely pitch black from outside the beam.

Nested in the forested foothills of Arashiyama, the Ukiyo Sanctuary Pavilion is a private contemplative retreat constructed from traditional cypress framing, Shou Sugi Ban (charred cedar), and hand-troweled earthen juraku walls. In classic Japanese architectural tradition (In Praise of Shadows), darkness is not an absence of light, but an active architectural material that must be carefully sculpted.

Recessed ceiling cans were forbidden by the architect to preserve the integrity of unblemished exposed cedar timber ceilings. Furthermore, modern LED fixtures typically blast surfaces with flat, sterile flood illumination, flattening the three-dimensional charred texture of the wood and washing out the delicate warmth of cedar resin.

LPA devised a scheme focused entirely on low-level tangential grazing and concealed perimeter reveals. Luminaires were hidden in knife-edge floor plinths and perimeter timber slots, casting micro-tangential beams (5° to 10°) upwards and downwards along the surfaces. Color temperature transitions dynamically from 2400K down to a candle-like 1800K as natural dusk descends over the Kyoto valley.

Utilized CONVEX C-25 micro-extruded cove profiles hidden inside the floating ceiling shadowline, casting a 120° batwing indirect wash across tatami mats with zero visible glare. Along the exterior timber corridor, miniature CYLINDRO X-40 solid aluminum cylinders with internal honeycomb snoots were surface-pinned to historic cross-beams, projecting a 12° knife-edge spot to highlight Japanese calligraphic scrolls without spilling onto surrounding plaster.

Perched on the 34th floor of a high-rise in Milan’s Porta Nuova district, the executive chambers for a European private equity fund feature floor-to-ceiling panoramic glazing framing the snow-capped Alps. The interior palette is uncompromisingly noble: honed dark basalt stone, smoked oak paneling, and patinated bronze millwork.

Executive work requires high visual acuity (minimum 500 lux maintained across the conference table and video-conference participants). However, corporate downlights typically create a chaotic ceiling dotted with glaring bright spots. This causes severe eye fatigue and produces intolerable reflections on the massive panoramic glass facade, obscuring the dramatic night panorama of Milan and the mountains.

Metis Lighting adopted a dual-layer strategy: Darklight Downlighting combined with Concealed Perimeter Wallwashing. APERTURE M-60 darklight fixtures with deep 45° cutoffs cast high-candela light precisely onto the conference surfaces while appearing virtually unlit from normal sitting angles. Perimeter basalt walls are softly washed by KINETIC G-WALL, balancing eye pupil adaptation and eliminating heavy cavern-like contrast.

Selected APERTURE M-60 with dark specular vacuum-metallized secondary reflectors. The luminaire achieves UGR < 8.8 even at 2,200 delivered lumens. STYLOS O-12 12° pinholes with cross-hair nadir louvers were deployed over executive credenzas and sculpture plinths, while DALI-2 DT8 controls modulate color temperature from 3500K during business meetings to 2700K for evening client receptions.

Standing directly on the Grand Canal, Palazzo Loredan is an iconic 15th-century Venetian Gothic palazzo built of porous Istrian marble, decorated with intricate quatrefoil tracery and slender multi-tiered loggias. The building is regularly exposed to saltwater flooding (Acqua Alta) and atmospheric humidity.

Drilling into the historic marble facade was strictly prohibited by the Venice Heritage Commission. In addition, fixtures had to endure complete saltwater submersion during high tides, while preventing upward glare from blinding gondoliers and water taxis navigating the dark canal.

The lighting team deployed sub-grade marine-grade fixtures directly into the underwater quay foundation. With internal 15° mechanical tilt and elliptical optical distribution, the fixtures graze upward along the Istrian stone pilasters, picking out the relief of the Gothic carvings while keeping the canal water surface dark and undisturbed.

Installed TERRA G-80 IP68 inground floodlights with 10° x 40° elliptical graze optics and internal honeycomb glare shields. The elliptical beam concentrates photon energy vertically along the columns without lateral spill into canal waters.
