Among the strategies that have been used to minimize bird collisions with buildings are gluing hawk silhouette decals to the glass, using glass imprinted with a ceramic fritting pattern, applying patterned plastic films, installing exterior shading systems that help birds see the building (as with the New York Times headquarters building in New York City), planting vegetation close to heavily glazed facades; and installing netting on the outside of large windows. The random pattern on Ornilux Mikado glass is UV-reflective and highly visible to birds, while being less noticeable to humans. Shown here is what birds see. Photo: Arnold Glas.

Ornilux glass, made in Merkendorf, Germany by Arnold Glas, has patterning of UV-reflective coating that is nearly transparent to humans but clearly visible to birds. Birds are able to see a broader spectrum of UV light than humans, according to the Arnold Glas website. The first installation of Ornilux bird-friendly glass was in 2006 on the glass façade of a 100-year-old indoor swimming pool building in Plauen, Germany. The building uses 2,700 square feet (250 m2) of insulated Ornilux SB1 glazing. Like other types of glass, Ornilux can be fabricated into a wide range of glazing systems, including high-performance double- and triple-glazed systems with low-emissivity (low-e) coatings. In the U.S., the New York City architecture firm FXFOWLE was the first to use Ornilux. The glazing was installed on a portion of the Center for Global Conservation at the Bronx Zoo, which was completed in 2009. (The bird-safe glass was originally specified for the entire building, but was value-engineered out for all but one corner conference room.) FXFOWLE principal Bruce Fowle, FAIA has been a leading proponent of bird-safe glazings, and his wife, Marcia Fowle, co-authored the 55-page Bird-Safe Building Guidelines , published in 2007 by the New York City Audubon Society .

Visually, the UV-reflective pattern on Ornilux glass is visible, but it is less apparent that many of the other strategies that have been tried to minimize bird collisions. To date, this glass has been used primarily on buildings where wildlife protection has been a high priority, such as nature centers, but as awareness of this problem grows, the use of this glazing, and competing products, may grow. In 2009, a new version of Ornilux glass was introduced, called Mikado (German for the game of "pick-up-sticks"). Rather than even striping, Mikado glass has a random pattern of lines. To date, several installations of Ornilux Mikado glass have been completed in Germany, but none in the U.S. Ornilux glass is distributed in the U.S. by Roeder Windows & Doors , which is advertising on its website the availability of Ornilux glass in its window and door products at no up-charge through June, 2011. The glass is also offered as an option on NanaWall operable glass wall systems. Environmental Building News will be running a more detailed review of Ornilux glass and, possibly, other glazing systems designed to minimize bird collisions in an upcoming issue.
