New York City Passes Country’s Most Wide-ranging Bird-friendly Building Legislation

Today, the New York City Council approved Proposed Initiative 1482B — to date, the most broad-reaching bird-friendly building policy in the country. The new policy requires that new buildings’ materials meet bird-friendly standards that greatly reduce collision risks to birds. The policy also covers major renovations that include modifying existing glass, and applies to construction across the city’s five boroughs.

“Bird-friendly building design should not be seen as an add-on or an extra,” said Dr. Christine Sheppard, Glass Collisions Program Director for American Bird Conservancy. “Many strategies for controlling heat, light, and even security can be bird-friendly strategies, too. These can be incorporated into almost any building style, but should be built into project design from the outset to minimize additional costs. That’s why this kind of legislation is so important.”

The following consortium of partners worked directly with the City Council, providing background on the problem of bird-glass collisions and insight into materials and design solutions: American Bird Conservancy (ABC), New York City Audubon (NYC Audubon), the New York Chapter of the American Institute of Architects (AIANY), the Bird-safe Buildings Alliance, and architects representing FXCollaborative and Ennead Architects.

“This bill is a compromise forged by our diverse consortium, which wrestled with and reconciled competing interests of many sorts — design, light, height, use, location, cost, bird mortality…. It’s a huge leap forward for long-term conservation,” said Kathryn Heintz, NYC Audubon Executive Director. “It will reduce collisions and save migratory birds whose numbers are declining dramatically. As a whole community, we must do better for the future, better for the sustainability of urban living, and better for the health of both birds and people.”

“It’s our ethical responsibility as members of the building industry to address the role of glass in bird population decline,” said Dan Piselli, AIA, LEED AP, CPHD, Director of Sustainability at FXCollaborative. “This informed our strategy for renovating the Jacob K. Javits Convention Center in 2013.” Once identified by NYC Audubon as the city’s top bird-killing building, it was renovated with the goal of not only making the facility more transparent and welcoming, but also making it bird-friendly. New glass incorporated patterns that birds perceive as an obstacle and that also reduce cooling costs. Bird deaths have dropped by 90 percent and the building now uses less energy since the renovations were completed.

"The materials and techniques that prevent bird collisions are already commonly used for a variety of reasons in our buildings; this legislation mandates their use in ways that also protect birds in cost effective ways,” said Benjamin Prosky, Assoc. AIA, Executive Director of AIANY and the Center for Architecture. “AIANY and its members are proud to have fought for this commonsense bill."

A recent study published in Science reported that the U.S. and Canadian breeding bird population dropped by more than one-quarter since 1970. Glass collisions are one major cause of this loss, killing up to 1 billion birds in the U.S. each year. According to NYC Audubon project Safe Flight, 90,000 to 230,000 birds die each year during their migrations through New York City alone. Fortunately, both home and commercial windows can easily be made safe for birds.
