Leo Villareal and Lifschutz Davidson Sandilands architects to illuminate the Thames

Londoners will see the Thames in a whole new light beginning this summer. In a collaboration between British architecture firm Lifschutz Davidson Sandilands (LDS) and U.S. artist Leo Villareal, up to 15 London bridges—including UNESCO World Heritage sites—will be outfitted with an array of new lighting for at least the next decade. The project, called Illuminated River, will highlight the bridges' unique sculptural and environmental qualities, breathe new life into urban spaces, and connect communities all along the waterway. This summer, Illuminated River will begin with four bridges—Southwark, Cannon Street, London and Millennium bridges—getting lit up. The massive installation will continue to be built over the next few years, with a further section to be completed in 2020, and an aimed completion date of 2022. The collaboration between artist and architect was natural, said LDS’s Alex Lifschutz in a statement. “Architects collaborate with many different species of being. Indeed, architects are many species of being,” he said. Villareal, who has previously illuminated bridges like San Francisco’s Bay Bridge, felt similarly. “We rely on each other’s views to achieve this great ambition," Villareal said. "The collaboration is so far a success because it is based on trust and the respect of one another’s expertise and unique vision.” The architects and artist worked together to use the latest in LED technology, along with custom software, to outfit the bridges to produce an effect that is, according to Villarreal, “gently kinetic.” While, Lifschutz pointed out, there's been a “huge revolution” in LED technology—in terms of efficiency, scalability, cost, color, control, and other attributes—in the wrong hands LED fittings are “a very potent destructive mechanism.” Lifschutz explained: “LED fittings are maybe five times more efficient than standard fittings. People have thought, ‘Well, that's fantastic. We'll save a lot of energy and the world will be all the better for it. And climate change will be that much further away.’ The unintended consequence of this high efficiency is that people use more of them. And the world has become brighter and jazzier as a result, which is a great shame." LDS and Villareal's answer is to use light “very judicially.” The architects and artist did a huge number of studies using the latest laser techniques. While the top surfaces of bridges are “straightforward,” the undersides—with all their supports and trusses—are “incredibly interesting and abstract,” said Lifschutz. “Each bridge has its own character,” he said. "It's like having 15 children—not that I do—but each one has a different character and each one deserve a different way of talking about it, of dealing with it.” They considered how to light the bridge as both a piece of art and architecture, working where the two intersected to manage the relationship between structure, form, and function in order find the best places to provide light and fix fittings, all while not affecting the structure, especially on the “very precious bridges.” “Both [Villareal and I] have a technical background in the color of light, the spread of light, the way in which light falls on surfaces, and the kinds of fittings or kinds of technical fittings that are available to make the magic happen,” explained Lifschutz. “And light is very magical, obviously.” Additionally, the river is not only a site of architectural life and preservation, but also of ecological vibrancy and conservation. The team had to do a number of ecological studies, some reportedly more thorough and substantive than those that had been done before, and research the effect of light on the creatures living in the Thames. “If you have a line of light that lies across the water, fish generally don't like to cross that,” explained Lifschutz. “It may affect spawning patterns in the shoreline and so on.” In their research, they discovered much of the existing lighting on London’s bridges was already detrimental to wildlife. “[The lighting] is spraying light everywhere; it’s the wrong color.” Many naturally uncommon colors and color temperatures—many of which are currently in use before the team’s intervention—negatively affect the wildlife swimming below. The competition to develop the river project was supported by the office of Mayor Sadiq Khan, received over 105 entries, and was done in collaboration with over 100 local organizations on and around the river. It required numerous approvals to work with listed structures. The local groups have "mostly been hugely enthusiastic,” reported Lifschutz. And it is apt that the project is titled Illuminated River—working at a scale Lifschutz calls “epic,” there will be integration across all 15 bridges to create a cohesive, unified effect and artwork “painting with light,” as Villareal put it, across the whole of London’s main waterway. “We hope Illuminated River will open up the riverside public realm spaces for people to linger, appreciate the enhanced architecture of the bridges, cultivate new opportunities, and encourage tourists to come to London and enjoy nightlife activities,” said Villareal. “It will celebrate the unique character and the amazing landmarks of the city through art.”

Pyongyang’s giant pyramid puts on a massive light show

A video released by Facebook page North Korea Girls 북조선녀성 reveals that an enormous LED light wall that has been added to the massive pyramidal Ryugyong Hotel in Pyongyang, North Korea. In the minute-long video posted Monday, seemingly taken from a car passing by the hotel, the facade of the hotel was lit with flashing animations of lotus flowers, ornate landscapes, spinning lights, and ending with a political statue standing in front of a backdrop of colorful fireworks. The social media page North Korea Girls is a community in Pyongyang, Korea. Affiliated with the website friend.com.kp, the page delivers anonymous pictures, videos, and news from North Korea with English-language narratives. Reports from various sources earlier this year say that the LED display was only added to a portion of the structure. The North Korean government is not readily open to foreign journalists, and whatever video has been made publicly available has likely passed through government censors, presumably for boosterism purposes. The 105-floor Pyongyang skyscraper has been empty since its groundbreaking more than 30 years ago in 1986. As Huffington Post reported, it is “the world’s tallest unoccupied building," and has been, “plagued by engineering problems (including crooked elevator shafts) and a lack of funding.” The post-modern, pyramidal structure was supposed to host “restaurants, offices, and hotel rooms.” It remains unclear whether or not the North Korean government is determined to complete its construction in the near future.

A closer look at lighting integration on Wilshire Grand's spine

Brought to you with support from
Over sixty years ago the original Wilshire Grand Hotel opened as the Hotel Statler, thanks to the City of Los Angeles, which issued the largest single building permit in their history for the construction of the $15 million project. That landmark legacy continues today, as the new 1,100-foot-tall Wilshire Grand tower lays claim to being the tallest building in Los Angeles, the tallest building in California, and the tallest building west of the Mississippi River.

The tower formally breaks from a 1974 ordinance requiring towers to have flat roofs for helicopter rescue in the event of fire. A tapered form was permitted due to advances in fire safety and building technology, such as a reinforced concrete central core that exceeds the city’s current fire code. The facade features a fully integrated, centrally controlled experiential LED lighting developed by StandardVision. The linear fixtures were custom made per floor, and installed throughout each of the tower's 73 floors. One centrally controlled system ties the entire system together. This allows possibility for the facade for incorporate full motion video, artwork, accent lighting, and brand signage as desired. All linear accent lighting was integrated into the glazing panels, and the fixtures were pre-installed in the facade contractor’s shop prior to site delivery. This unitized approach minimized staging time on-site and allowed for a smooth installation workflow. Joshua Van Blankenship, vice president of media platforms for StandardVision, said this was one of the biggest challenges of the project. Another technical challenge was to ensure lighting occurred seamlessly despite traveling over expansion joints in the facade and encountering over 200 parametrically controlled panel widths. “Resolving these two factors with Benson [the facade contractor] allowed us to save tens of thousands of man-hours in exterior installation, and focus our budget on providing the technology solution the architect wanted without a single SV change order,” he said.
Penetrations through the building envelope were reduced to a singular point per floor level. A small kick plate access hatch offers accessibility from the interior. This utility space houses LED drivers for the fixtures and wiring for the system. The detailing and design coordination of this moment in the facade went through rigorous proof of concept water-testing to ensure performance. Van Blankenship credits a close design-build relationship between documentation and fabrication teams at Benson and StandardVision for the success of the integrated lighting system. “Our designers in L.A. were regularly working these shifted-hours to have time to overlap with Benson's Singapore team, and by the end of the process, we were incredibly efficient in defining how our respective scopes were going to relate.” he said. “Throughout this entire process AC Martin, Turner and Rosendin (the electrical contractors) were great partners in helping to make this hybrid system work.” Wilshire Grand’s lighting system highlights a robust curtainwall system that was optimized for California’s seismic loads and solar gain. Thornton Tomasetti developed a parametric facade panelization model that consolidated and synchronized information in required for architectural documentation and specialty construction. Concurrently, Glumac developed energy models and shading studies throughout the design process to study building envelope performance. The models take into account shade from DTLA’s surrounding context cast onto the tower, proposing a series of varied fin depths along the south facade. This level of study saved curtain wall material while maximizing the shading potential of the building envelope. California’s Title 24 energy code limits glazing to 40 percent window-to-wall ratio (WWR), but with these advanced parametric modeling and analysis tools, the design teams were able to demonstrate a larger WWR of 50 percent could still outperform California code baseline through careful specification of glazing material, insulation values, and shading schemes.

An active light display animates the facade of a new office building in Warsaw, Poland, highlighting the Wola neighborhood’s transition from industrial manufacturing to a new residential and office district. The Prime Corporate Center was designed by Chicago-based architectural firm Solomon Cordwell Buenz in conjunction with the Warsaw office of Epstein.
  • Facade Manufacturer Guardian Glass (glazing); Aluprof / Widok (curtain wall)
  • Architects Solomon Cordwell Buenz (design architect); Epstein (local architect); Golub GetHouse (developer)
  • Facade Installer Widok
  • Facade Consultants Candelux (lighting consultant); Luxmat (LED programming consultant)
  • Location Warsaw, Poland
  • Date of Completion 2016
  • System unitized curtain wall with integrated LED
  • Products MB-SR50N HI Mullion-transom wall by Aluprof
The building’s design addresses varying vehicular and pedestrian arrival points by segregating car drop-off from those arriving by public transit. An additional 15 stories of offices above an eight-story base is coordinated with the scale of the street. Martin Wolf, principal at Solomon Cordwell Buenz, said the simplicity of the building allowed his team to focus on a sophisticated facade composition: "This project became an exercise in pattern, geometry, and very subtle layers of texture. We achieved this through the combination of fritted glass panels, clear view glazing, and a selective articulation of the curtain wall system." At night, a grid of LED lights incorporated into the unitized curtain wall system to produce a delicate, shifting array of color and pattern that dramatizes the exterior wall. Guardian Glass's Poland manufacturing facility provided glazing and worked with the project team to integrate LED wiring into the curtain wall. These linear lights are wired into a central computer housed in the building, which hosts a computer sequencing program. The technology allows for Prime’s facade to be easily programmed by the building operator, who can flexibly produce variation in lighting schemes. Prime’s building envelope features integrated building systems to control the MEP/FP systems, a monitoring system that optimizes water and electrical power consumption, a heating recovery system, and an interior shading system to help manage solar heat gain. The office plates are designed for future flexibility, incorporating a raised floor system and column-free interior space. These features contribute to the building’s BREEAM certification, a UK green building rating system. Wolf said the Solomon Cordwell Buenz’s office continues to have an ongoing interest in integrative lighting techniques, and that LEDs allow for an impressive amount of variables for any project team to work with. "The beauty about LED is that if you wire it properly, you have an infinite array of color, sequencing, intensity, and timing." Facades like Prime’s, which have the capacity for coordinated building-scale lighting schemes, have the opportunity to communicate with the city utilizing data analysis, upcoming cultural events, and atmospheric conditions. According to Wolf, Prime is an “incredible work of art,” and adds “a needed touch of whimsy” to the urban context. A video of the facade lights in action can be seen below:
