In May, German architectural firm Ingenhoven Architects broke ground on Kö-Bogen II, a sustainable mixed-use development envisioned as the “new green heart” of Düsseldorf , Germany. Designed to visually extend the adjoining Hofgarten park into the inner city, Kö-Bogen II wraps the sloping facades of its two buildings with hornbeam hedges that total nearly 5 miles in length. The hedges and turfed rooftop spaces will also help purify the air and combat the city’s heat island effect by providing a cooling microclimate. Located at Gustaf-Gründgens-Platz, Kö-Bogen II will serve as a commercial and office complex covering 42,000 square meters of gross floor area offering retail, restaurants, office space, local recreation and a five-story underground parking garage with 670 spaces. The development comprises a five-story trapezoid-shaped main building and a smaller triangular building that cluster around a valley-like plaza. The sloping facades, which will be planted with hornbeam hedges, open up the plaza to views of the iconic Dreischeibenhaus and the Düsseldorf Theater nearby. The architects will also be refurbishing the roof, facade and public areas of the Düsseldorf Theater. “In order to do justice to the overall urban design situation, the design of Kö-Bogen II deliberately avoids a classical block-edged development such as that along the Schadowstrasse shopping street,” the architects explained in a press release. “In addition, the idea of green architecture has been applied systematically, thus distinguishing the development from conventional architectural solutions.” Related: A rainforest-like green heart grows within Singapore’s Marina One Ascending to a building height of 27 meters, the hornbeam hedges will offer seasonal interest by changing color throughout the year. The turfed surfaces planted on the triangular building’s sloped facades will be accessible to passersby, who can use the space as an open lawn for rest and relaxation. Kö-Bogen II is slated to open in the spring of 2020. + Ingenhoven Architects Images via CADMAN

Wild bees are building nests with plastic

While plastic use is going out of vogue with more enlightened humans, it’s catching on with Argentinian bees. Scientists don’t know why Argentina’s solitary bees are now constructing nests out of plastic packaging left on crop fields. Unlike the large hive model with queens and workers, wild bees lay larvae in individual nests. Researchers at Argentina’s National Agricultural Technology Institute constructed 63 wooden nests for wild bees from 2017 to 2018. They later found that three nests were entirely lined with pieces of plastic that bees had cut and arranged in an overlapping pattern. The plastic seemed to have come from plastic bags or a similar material, with a texture reminiscent of the leaves bees usually use to line nests. Related: McDonald’s creates McHives to raise awareness of the world’s decreasing bee populations The scientists’ study, published in Apidologie, is the first to find nests entirely made from plastic. But researchers have known for years that bees sometimes incorporate plastic into nests otherwise made of natural materials . Canadian scientists have chronicled bees’ use of plastic foams and films in Toronto. Like the Argentinian bees, bees in Canada cut the plastic to mimic leaves. Scientists aren’t yet sure what to make of this architectural development. “It would demonstrate the adaptive flexibility that certain species of bees would have in the face of changes in environmental conditions,” Mariana Allasino, the Argentinian study’s lead author, wrote in a press release translated from Spanish. But will the plastic harm the bees? More research is required to gauge the risks. While microplastics are a huge threat to marine animals, some enterprising creatures find ways to use trash to their advantage. Finches and sparrows arrange cigarette butts in their nests to repel parasitic mites. Stinky but effective. “Sure it’s possible it might afford some benefits, but that hasn’t been shown yet,” entomologist Hollis Woodard told National Geographic. “I think it’s equally likely to have things that are harmful.” Via National Geographic Image via Judy Gallagher
