About the Challenge
Buildings account for approximately 40% of US carbon emissions. In this challenge, you will design HVAC control agents using Google's open-source building simulator to minimize carbon emissions and operating costs while maintaining comfortable building conditions.
Your solution could have massive real-world environmental impact. The challenge has now concluded — see the full results.
