New Yorkers Invited to Choose their Favorite App in Facebook Vote

July 2, 2012- NYC Digital and the Mayor’s Office of Long-Term Planning and Sustainability—which is responsible for implementing PlaNYC, the City’s comprehensive sustainability plan—have announced the winning apps from Reinvent Green, the City’s first sustainability hackathon, a collaborative community coding event in which developers worked together to solve a range of challenges using digital technology. More than 100 developers and designers gathered over the weekend at NYU-Poly in Downtown Brooklyn to create digital tools and apps using open City data that focus on encouraging sustainability and promoting green initiatives and efforts that will help engage New Yorkers to meet PlaNYC goals. The winning apps can be viewed at and

"The innovation on display at this weekend’s Reinvent Green Hackathon shows just how much we can achieve when New York City's tech community works together,” said Chief Digital Officer Rachel Sterne. “That partnership and creativity are crucial elements in fulfilling the digital roadmap that Mayor Bloomberg has set for the City of New York. In two short days we saw the development of powerful apps that help New Yorkers recycle, find green markets, pool bicycles and much more. We would like to thank all who helped to make Reinvent Green possible, including over 100 individuals from across the boroughs and around the country who dedicated their weekend to the event, and our fantastic partners at NYU-Poly, Downtown Brooklyn Partnership and Brooklyn Beta.”

“City government has undertaken many initiatives under PlaNYC, ranging from new parks to more transportation choices to energy efficiency retrofits,” said David Bragdon, director of the Mayor’s Office of Long-Term Planning and Sustainability, “but creating a greener, greater New York requires the involvement of all residents. The apps developed this weekend will tap into New Yorkers’ interest in living more sustainably.”

From now until July 15, Facebook users will have the opportunity to vote for their favorite app developed during the hackathon. Voting will take place at The app with the most votes will be announced later that month.

A panel of judges evaluated the apps and online tools and awarded prizes in the following categories:

Best App for City Crowdsourcing: ReBounty
Sean Auriti, Peter Gerber, Johanna Levy, Lydia White

ReBounty is an easy way to find and list unwanted household and personal items in an effort to reduce the amount of consumer-waste that is thrown out in urban areas every year. You can submit bounty by email, through the web, or through the iPhone app. You can also set up alerts to be notified when items you are looking for are posted near you.

Best App for Recycling: GreenCan
Sarah Azpeitia, Jason Pearson, Matt Pestritto, Margaret Plaisted

GreenCan lets users locate their nearest public recycling trash can, provides information for recycling organics and electronics, and provides valuable feedback back to the City of New York for future recycling can placement.

Best App for Transportation: Bike Pooling
Marine Boudeau, Lori Hoffman, Isaac Lewis, George Magiros, Yannell Rodriguez

Think of it as car pooling but for bikes. Find people who commute on the same path as you and start riding with them every morning/evening. The app aims to make biking in the City safer, convert more people to bike commuting and help New Yorkers make new friends.

Anton Granik and Matthew Ruttley

This app enables competition among the different neighborhoods in NYC as to which is the greenest. The app includes a filterable league table with green data showing what each neighborhood is strong at (i.e.: oil & energy consumption, trees planted), as well as markers to show what a neighborhood should do to beat the rest of the competition.

The judges for Reinvent Green included: Jessica Lawrence, managing director of New York Tech Meetup; Jenny Ahmed, founder of Pia Car; Tyler Mincey, co-founder of Brooklyn Beta; Micah Kotch, director of Incubator of Initiatives, NYU-Poly; David Bragdon, director of the Mayor’s Office of Long-Term Planning and Sustainability; and Ron Gonen, deputy commissioner of Recycling and Sustainability, NYC Department of Sanitation for the City of New York.

“During this two day event hosted by NYU-Poly, the energy and talent of programmers, developers and design teams was exemplified by their incredible collaborative effort in creating digital tools and apps focusing on encouraging sustainability, and promoting green initiatives to create a greener, greater New York,” said Jerry Hultin, president of NYU-Poly. “This event set a great example for current and future students interested in engineering – and demonstrates how education coupled with hands-on experience, can be used to tackle the most pressing issues facing our cities today. As a center for innovation, invention and entrepreneurship, NYU-Poly was the perfect setting for the green hackathon, and in keeping with our mission, we applaud and support NYC Digital’s efforts to realize NYC as the world’s leading digital city.”

“The success of the Reinvent Green hackathon is just another sign of how Downtown Brooklyn has emerged as one of New York City’s centers for innovation, creativity, and entrepreneurship,” said Tucker Reed, President of the Downtown Brooklyn Partnership. “With a variety of office spaces both large and small, world-class academic and cultural institutions, and a vibrant shopping and dining district, there is no better place to continue to grow the tech industry than right here in Downtown Brooklyn.”

“We want to help people make something they love, and we love New York,” said Chris Shiflett, co-organizer of Brooklyn Beta. “Reinvent Green is the perfect combination of these passions, and we're excited to have partnered with the City of New York for a fun and rewarding weekend.”

“The tools and apps developed at Reinvent Green illustrate that innovation and technology can play an instrumental role in incorporating sustainability efforts into everyday living,” said Francis J. Murray Jr., President and CEO of NYSERDA. “With events like Reinvent Green, and initiatives like Governor Cuomo’s Cleaner, Greener Communities program, the State and City are committed to making sure all New Yorkers have greener, healthier communities in which to live and work.”

"It's been incredibly rewarding to see all the participants come together at Reinvent Green to produce such a good set of tools and applications built on city data," said Usman Haque, Director of Cosm's Urban Projects Division. "At Cosm we believe that a 'smart city' is founded on smart and engaged citizens, building tools of their own for making sense of and transforming urban environments, and so we're delighted the Reinvent Green hackathon has helped pave the way for a smarter New York City."

“Reinvent Green brought together the City’s brightest young talents to create applications that provide solutions to manage waste recycling, to conserve water and to bring environmental awareness to neighborhoods,” said Brian Blauvelt, president, Energy Infotech NYC. “It is events like these that are paving the way for New York City to becoming the No. 1 energy infotech hub in the world. These types of events perfectly align with the mission of Energy Infotech NYC (EITNYC). We (EITNYC) are proud to support NYC Digital and PlaNYC and hope to host more valuable and fun competitions to spark new cleantech, IT and digital innovation in the future.”

“The Reinvent Green Hackathon underscores the powerful innovation possible when government data is unlocked and applied by New York City’s talented designers, developers, and thinkers to address real-world challenges,” said Andrew Nicklin, Director of Research and Development at the Department of Information Technology & Telecommunications. “Every one of the demonstrated projects amplifies the importance of collaborative communities and networks to help keep our city on the leading edge of environmental sustainability.”

Throughout the weekend, developers used a variety of the City’s open datasets in their designs. Several new datasets were also unveiled to join existing sets such as energy consumption by zip code, the New York City Community Air Survey, solar maps, tree surveys and NYC climate change projections, among others.
