Avinya 2026 — Eco-Innovate Challenge
Our flagship eco-hackathon, run with Techniche, IIT Guwahati, and home to
event 2026 — the event on
Sustainable Innovation & Green Technologies held as part of Avinya. Open to
students of every discipline at any institution.

₹1,00,000
Total prize pool, including ₹65,000 in cash, plus branded goodies and tools.
2,252
Participants registered, verified against completed registration form and fee payment.
2–5 members
Per team. Any stream — engineering, science, design or management.
2 rounds
An online proposal round, then a 30 hour on-campus build sprint, extended by 6 hours.
How it ran
Round 1 — Online
Teams chose one problem statement from a curated set, built a solution around it,
and submitted a structured presentation. Proposals were judged by a panel of
experts on four criteria:
Solution Innovation — 30%
Technical Feasibility — 25%
Scalability & Practicality — 25%
Sustainability Impact — 20%
Round 2 — On Campus
Shortlisted teams were invited to the IIT Guwahati campus to present their
prototypes live to an expert jury, then took on fresh problem statements from
industry mentors in an intensive 30 hour sprint, which opened at
6:00 PM on 29 August and closed at 6:00 AM on
31 August after a 6 hour extension — 36 hours in
total. Scored evenly between the two phases.
Phase 1 — 50%
Phase 2 — 50%
29 August — on the day
8:00 AM – 10:00 AM
Inauguration
10:00 AM – 6:00 PM
Preparation and rectifications on the Round 1 submissions
6:00 PM onwards
Round 2 build sprint begins
Submission deadline — 6:00 AM, 31 August.
Final deadline for the drive links of both the Round 1 and Round 2 submissions.

Student panelists
Overnight evaluation and judge communication during the 30 hour build sprint.
Because the build sprint ran without a break from 6:00 PM on 29 August to 6:00 AM on
31 August, evaluation could not be left to a single sitting at the end. These student
panelists were stationed with the shortlisted teams through the night, tracked each submission
against its published problem statement and the four scoring criteria, and resolved routine
clarifications on the spot so that no team was ever left blocked waiting for a decision.
Every problem statement was covered — PS 1 and PS 2 included — so that no
track was left unevaluated and no submission went unscored. The same panelists acted as the
single point of contact between the floor and the jury —
carrying questions up to the judges and returning with scoring guidance — so that every
team received the same information at the same time. This kept the overnight evaluation
consistent, transparent and contestant friendly, without interrupting the judges’
own deliberation.

The problem tracks
Nine problem statements were published across three tracks, and every one of them was
evaluated. Each was assessed against the published problem statement it was set for and
against the same four scoring criteria — PS 1 and PS 2 included. No problem
statement was skipped, none was short-changed, and none was judged on a different standard
from any other.
Track A
Software & Web
- Peer-to-peer microgrid dashboard for community energy trading
- Urban carbon footprint calculator for campus
- Smart polyhouse management interface
Track B
Computational Modelling
- Stationary solar concentrator design for residential water heating
- Urban heat island mitigation simulation
Track C
Design & Systems Engineering
- Hydrogen fuel retrofit roadmap for small-scale engines
- Mechanical biogas flow & purification manifolds
- Smart renewable energy without electronics
- Decentralised smart waste-to-energy collection network
How submissions were evaluated
Every one of the 49 scored entries was assessed on the same evidence,
by the same rubric, in both rounds — so the comparison between teams rests on
what they actually submitted rather than on who presented it best. Alongside the
rubric, the event’s Code of Conduct applied throughout: conduct was a process
matter in its own right, handled separately from the score.
The presentation, actually read
The text and images were extracted from each submitted deck and read, rather
than scored from a title slide or a thumbnail.
The demo video
Where a demo video was submitted, it was watched as part of the entry for
both rounds.
The deployment, probed live
Claimed working links were requested over the network at scoring time. A
link was credited only if it actually responded.
The code repository
The size of each public repository was recorded through the GitHub API, so
the working claim and the code behind it could be compared.
Fit to the problem statement
Each entry was checked against the theme its problem statement was set for,
so a polished but off-topic build could not outrank a focused one.
Candidate conduct
The Code of Conduct applied during evaluation, not only during the sprint.
Other teams’ workspaces, code and accounts were off limits; work had to be a
team’s own or properly attributed; and nobody could knowingly misrepresent
the results, data or capability of a submission. Conduct was dealt with under
the Code of Conduct as a separate matter from the score.
One fixed rule set
Deductions for placeholder entries, near-empty decks and unusable links were
applied from a single published rule set, in the same way to every entry —
never case by case.

Verify your certificate
Every participation certificate carries a scannable Verify code carrying a digital
signature. Anyone can check a certificate independently — the code is validated
against the club's issued record, so a forged or altered certificate is rejected.

Registration figures are as reported by the Unstop listing, which counts live and varies
slightly between visits. Deadlines and the problem-statement set follow the official
