Echo{logies} is the 2026 exhibition of Data Through Design, an independent collective who organize an annual art exhibition featuring works that creatively analyze, interpret, and interrogate data made available on NYC Open Data.
Visiting the Exhibition
The exhibition is open to the public daily from 12pm to 7 pm during Open Data Week. On March 21, we will host an opening event that requires RSVP.
When: March 21 – April 5, 2026, 12:00pm – 7:00pm
Where: BRIC, 647 Fulton Street (at Rockwell Place), Brooklyn, NY 11217
Opening Event: Saturday, March 21, 6:30 – 8:30 PM; RSVP.
About Echo{logies}
The projects in Echo{logies} work with the bodies of knowledge, or “-logies”, that reverberate through New York City’s data. They explore ecosystems and cycles of life expressed in data; the rhythms of growth, decay, renewal, and transformation as they “echo” through data, and the interplay between human and non-human worlds.
This year’s theme engages with questions such as: How can the city, and data itself, be understood as ecological and cyclical? How might data be materialized, embodied, or inscribed by natural processes? What accumulates, erodes, regenerates, lingers as traces, or resonates as echoes?
The work in this exhibition makes data felt, witnessed, or transformed—through physicalization, interaction, or by exposing how nature itself records and inscribes change. The artworks engage with living systems, natural or urban ecologies, or information ecosystems, and examine materiality and craft, murmurations and flows, entropy and genesis, and the sublime scale of ecological change.

Sneha Srivastava – What’s Lost in the Waters? Dive into NYC’s Flood Vulnerability Index
The goal of this project is to visualize the variables included in New York City’s Flood Vulnerability Index dataset. The key visualization is a three-dimensional interactive model, mapping the Flood Susceptibility to Harm and Recovery Index against the median household income of each census tract within the city, in addition to maps of future flooding scenarios. As such, the project tackles issues of environmental justice and sustainability, while addressing the policy implications of climate resilience in different neighborhoods.
The Cloud is a Place in Brooklyn
In this speculative design workshop, we ask: What if our data infrastructure lived in our neighborhood parks, schools, or community gardens? What if a data center didn’t just store files, but also used its excess heat to warm a public pool in the winter? What if your neighborhood’s digital history was stored in a “Community Memory Bank” that you helped manage? What if data infrastructure was owned by communities and served community needs?
Apurva Jhamb – Brooklyn Through Data Design : Mapping Place, Power, and Urban Systems
Centered on Brooklyn, the event will showcase a series of data-driven maps and visual narratives created using NYC Open Data datasets related to housing, land use, landmarks, environmental conditions, and neighborhood change. The session will demonstrate how public data when paired with thoughtful design can move beyond technical analysis to become an accessible storytelling tool for communities, planners, designers, and civic technologists.

Data for Disaster Recovery and Resilience: Exploring NYCEM's Hazard History Consequence Tool and Recovery Dashboards

Tracking NYC Trash: Using Open Data to Understand and Improve the City’s Waste System
2026-03-23 17:00 - 18:00 | https://opendataweek.nyc/event/tracking-nyc-trash-using-open-data-to-understand-and-improve-the-citys-waste-system/
Every trash bag on the curb tells a story about what we buy, what we waste, and how our city works behind the scenes to manage it all. Yet for most New Yorkers, what happens to our trash after collection remains largely invisible. This session pulls back the curtain, showing how publicly available data can help residents better understand New York City’s waste system and use that knowledge to push for smarter, fairer, and more sustainable solutions. Led by the volunteer team behind Track NYC Trash — a project of the Brooklyn and Manhattan Solid Waste Advisory Boards — this session explores how open data can become a powerful tool for understanding waste management across the five boroughs.
Participants will receive a guided, hands-on demonstration of the Track NYC Trash dashboards, which translate complex datasets from the NYC Department of Sanitation and other agencies into clear, accessible visuals. Using sources such as DSNY’s Monthly Tonnage Data, the 2023 Waste Characterization Study, and Census-based population figures, this session will highlight key trends in recycling, composting, waste export, and neighborhood-level performance. Attendees will learn how to interpret these numbers, connect them to everyday experience, and use them to better understand whether the City is meeting its stated waste and climate goals.
Designed for residents, advocates, students, journalists, public servants, and curious neighbors, this event welcomes anyone who cares about their community and wants better information to support meaningful change. No technical background is required. Participants will leave with practical tools to engage in data-informed advocacy — and with a deeper sense of how open data can help build a cleaner, more transparent, and more accountable New York City.

Open Data Lightning Talk Showcase
2026-03-23 18:00 - 19:30 | Office of Technology and Innovation, 2 MetroTech Center 5th Floor, Brooklyn, New York, 11201, United States of America
Come to the NYC Office of Technology & Innovation offices at 2 MetroTech Center in Downtown Brooklyn for a series of lightning talks, each of which explores how open data interacts with aspects of everyday life. Afterwards, join us for a happy hour a few blocks away at Sound & Fury Brewery and Kitchen (141 Lawrence St, Brooklyn).
These lightning talks will cover projects on the price of groceries, picking public schools, deciding delivery routes, applying to city jobs and compliance for small property owners. Full details of the talks will be added as they get confirmed.
Andre Debuisne “Using Open Data to accurately generate hyperlocal delivery routes in NYC”
Hudson Shipping Co generates its own delivery routes using in-house optimization technology. Part of the input data comes from NYC Open Data, which helps the last-mile operator find the best route for a given day, based on road conditions, planned street closures and many other data points.
Adrian Liang “Applying to NYC’s public high schools by harnessing NYC Open Data resources”
Every year, over 70,000 NYC public middle school students take part in the high school application process. This involves researching and deciding what programs to list on applications from over 900 possible high school program choices. NYC-SIFT aggregates public data from over 20 different datasets found on NYC Open Data and NYC DOE InfoHub. This talk will include a discussion of relevant datasets, how this data is organized, and how students and parents use this data to make informed decisions during the high school application process.
Charles Ludwig “One Search, 4,000+ Careers: Unifying New York’s Public Sector Government Job Market”
Navigating public service careers shouldn’t require checking ten different websites. This talk explores the development of NY Gov Jobs, a unified platform that aggregates over 4,000 active salaried listings across NYC City agencies, New York State, CUNY, SUNY, the MTA, public health systems, and the NYPL. We’ll discuss the technical challenges of normalizing data from multiple jurisdictions and how a single, browser-friendly interface can democratize access to public sector employment.

Shiva Muthiah “PriceWise – A community-built grocery price database for budget-conscious people”
This talk will demo the tool PriceWise (https://www.pricewise.nyc) — a community database of food prices that helps people digitize purchase receipts and draws from NYC Open Data to connect them with stores and neighborhoods. As New Yorkers struggle with inflation, this tool aims to help them work together to pool pricing information.
Parris Taylor “From Transparency to Decision Infrastructure”
New York City has achieved something rare: a deeply structured, publicly accessible regulatory data ecosystem. But access is not the same as usability, and transparency is not the same as prevention. As an operator managing real assets in NYC, I’ve seen how DOB, HPD, FDNY, and DOF datasets remain difficult to operationalize for small property owners. Compliance still requires interpretation, coordination, and judgment across fragmented systems. This session explores how open data can evolve from static reporting to structured decision support. Using Brick, a compliance tool that helps identify regulations, as a case study, we will examine entity resolution across BBL and BIN identifiers and the role of AI in translating public datasets into building-specific risk signals and guided action.

The City That Never Sleeps: Forecasting NYC’s Noise Complaints with Bayesian Models
2026-03-24 16:00 - 17:00 | https://opendataweek.nyc/event/the-city-that-never-sleeps/
This presentation looks at how everyday noise in New York City changes from neighborhood to neighborhood, across the days of the week during the summer. Using several years of NYC 311 data, it goes beyond simply counting complaints to ask a more practical question: how confident can we be that some areas are actually noisier than others?
Data Engineer Moses McCall will introduce Bayesian modeling in an intuitive, non-technical way, focusing on uncertainty as something we can measure rather than ignore. Interactive maps will be used alongside the analysis to make citywide patterns easy to explore and compare. Finally, the models will be tested against more recent data to see how well these patterns hold up over time, comparing what the models expected with what actually happened.

Walk the Data: Mapping User Experience (UX) Mobility on NYC Streets
2026-03-24 16:00 - 18:00 | Metrotech Walk, Metrotech Walk, Brooklyn, New York, 11201, United States of America
Join this hands-on walking workshop that turns NYC streets into a living lab! Together, we will test a custom, data-enabled pedestrian routing system built from publicly available layers such as sidewalks, pedestrian ramps, traffic volumes, thermal comfort, tree canopy, and other walkability indicators. The goal is to see what these datasets capture about moving through the city and what they miss. This approach, called UX Mobility routing, was developed and tested in Milan and is now being applied to a selected NYC area to spark new insights on inclusive, experience-aware mobility.
Led by moderators from Systematica and Transform Transport, participants will follow the predefined route in small groups and use a simple guided toolkit to document the sensory, cognitive, emotional, and physical side of the walk. We will consider factors like noise, crowding, comfort, clarity, and perceived safety, then compare lived experience with what the mapped layers suggest. The session concludes with a collective data–experience gap map and a set of takeaways on how NYC Open Data could better reflect real walkability through new layers, combinations of data, or proxy indicators such as using traffic patterns to estimate noise. Open to everyone, with no technical background needed, all mobility levels welcome, and materials provided.
The meeting point for this event will be in front of 5 MetroTech Center in Downtown Brooklyn.
