Are you interested in renewable energy, climate change and technology? Then the Boston Cleanweb Hackathon is for you! Do you know how to code like a pro or design a website? Do you have a plethora of knowledge about sustainability and energy efficiency to share? Are you a student or an established member of the Cleanweb community? All expertise are welcome to participate in the 5th Annual Boston Cleanweb Hackathon! We say the more diverse the better.  

Hosted by the Massachusetts Clean Energy Center in partnership with Greentown Labs, the Boston Cleanweb Hackathon is a weekend-long technology challenge. In teams, you will compete for cash prizes in an effort to create a user friendly web or app based platform that will help consumers and businesses use energy and natural resources more efficiently.

The competition takes place at LogMeIn in Boston’s innovative Seaport District. The event kicks off with a team formation mixer and challenge presentations on Friday, April 1st and then coding begins the morning on Saturday, April 2nd. Participants have two days to create an application that addresses energy, waste, water, transportation, food or other energy and sustainability issues. We wrap up on Sunday afternoon with pitches to a panel of six judges and awards ceremony. Lots of food and coffee will be provided.

The Hackathon is open to everyone 18 years or older (unless accompanied by an adult). You can come with a team already formed or build a team during the weekend. Participants must appear in person to pitch his or her submission at the judging event on Sunday.  

If you are an entrepreneur and plan for your submission to benefit your company, you are welcome to participate in the Hackathon. However, please note that you may not create code for your submission prior to the Hackathon and only work performed at the Hackathon will be eligible for cash prizes.

Anyone is welcome to join us for the weekend’s events as a spectator.


Submissions must be received in person by 2pm ET on Sunday, April 3, 2016.

After all entries are submitted, teams will each do a short pitch in front of the judges, which will include a brief opportunity for questions from the judges.

Your pitch should excite the judges and relay to them a good understanding of how your app works. Ideally you will present a fully functioning app, but if your team isn't quite there yet you can show the judges how your app will function and what else you will need to get it there.

Apps will be judged on a range of criteria such as content, sustainability, impact, functionality, originality and design.

Judging Criteria

  • Concept
    What's the idea? How does it work?
  • Sustainability
    What are the benefits in terms of environmental sustainability and efficient use of resources?
  • Impact
    Does it tackle a major problem or respond to a key industry need? Does it have the potential to change user behavior or make an impact on resource use?
  • Functionality
    Does it work? What has the team been able to accomplish over the course of the weekend? An OK product is much better than a really great PowerPoint deck.
  • Originality
    Is this something we've seen or heard before? Is it an update or a retread of something else, or is this entirely new?
  • Design
    How does it look? Has the team put thought into the user interface? Is it fun or attractive to look at?
