+## Event Summary
+On October 7, the **Green Hackathon** was hosted as part of the Green Lab course in the Master of Computer Science program.  
+Students participated actively, sharing innovative sustainability ideas and engaging in thoughtful discussions.  
+The event fostered collaboration, creativity, and an inspiring atmosphere centered around **green software innovation**.
+
+---
+
+## Overview
+The **Green Hackathon** encourages students to design **innovative, sustainability-focused software concepts**.  
+Rather than implementing solutions, teams focus on creativity, impact, and societal relevance.  
+Each group identifies a sustainability problem, proposes a novel software-based idea, and presents its potential contribution to greener computing.
+
+---
+
+## Results
+
+All groups were evaluated by a jury composed of two guests — Pooja Rani and Tristan Coignion — and the teaching team: Ivano Malavolta, Vincenzo Stoico, as well as the course teaching assistants, who brought valuable insights and perspectives to the judging process.

+## Project Descriptions
+
+### GreenPrompt - Making AI Greener at the Human–Model Interface
+LLMs consume significant energy, but users don’t see the cost. GreenPrompt wants to be a lightweight SLM companion that rewrites/optimizes prompts locally before sending them to the LLM. It does so by guiding users to shorter, structured, greener prompts with minimal accuracy loss.
+
+### ClearSky
+In a world were people spend most of their time in front of a screen, this is a game that rewards putting down your phone. Your screen time clouds the digital sky, and every unplugged minute clears it.
+If attention is the new currency, energy is the hidden tax. ClearSky turns that hidden tax into a living visual.
+
+### Sustainable heating for “Free” - IT for Sustainability
+Electricity prices and carbon emissions fluctuate throughout the day, with cleaner periods aligning with high renewables output. The idea is to automate schedules for devices to avoid extreme prices. A smart boiler, for example, can automatically schedule heating for low-price, low-carbon times.
+It’s easy to install—simply replace the old unit and connect it to Wi-Fi.
+
+### GreenLint: Code Smarter, Save Energy & Save the Planet
+A revolutionary Python linter that makes your code energy-efficient automatically. Where clean code meets clean energy for a sustainable future.
