About the Project

The Colorado Sustainability Hub is a transformative statewide digital infrastructure initiative that consolidates sustainability and well-being data from across Colorado into a unified, accessible, and interactive platform. By enabling intuitive access to complex data, the project fosters collaboration among community members, policymakers, and researchers, empowering them to engage with and draw actionable insights from regionally relevant information.

The project supports researchers, policymakers, and community members by making complex information easier to find, interpret, and use through community-driven design, natural language processing, geospatial integration, and advanced data workflows.

Project Goals

  1. Centralized Data Accessibility - A comprehensive online platform aggregating sustainability and well-being data from diverse sources
  2. User-Centric Design - Platform tailored to user needs through community engagement and participatory design
  3. Community-Driven Research - A shared resource where community members can contribute, curate data, and collaborate
  4. Educational Enhancement - Hands-on learning opportunities for undergraduate students across partner institutions
  5. Advanced Data Aggregation - Natural language processing and machine learning for conversational AI interfaces
  6. Evidence-Based Decision-Making - Tools for community planning, economic development, and environmental stewardship
  7. Enhancing Community Well-Being - Actionable, accessible sustainability data for Colorado communities

Bili: AI-Powered Sustainability Assistant

Bili is an AI-powered chatbot that provides access to Colorado’s publicly available economic, ecological, and social data related to environmental stewardship. Users can submit environmental queries to Bili, which uses large language models to provide research-backed answers about topics like climate impacts on Colorado.

BiliCore Framework

The team released BiliCore, an open-source framework for evaluating large language models in sustainability contexts. BiliCore provides:

  • Modular tools for automated testing and benchmarking
  • Prompt template management
  • Model-switching experiments
  • API-based evaluation capabilities

BiliCore enables objective comparisons across varied tasks and intents, informing model selection for the Hub. It was presented at the NAIRR Pilot Annual Meeting and accepted as Late-Breaking Work at ACM COMPASS 2025.

NAIRR Pilot Program

The project also received support from the National AI Research Resource (NAIRR) Pilot program (Allocation NAIRR240197), providing cloud computing credits for AI development:

  • AWS Credits: $41,678 for ETL pipelines, SageMaker ML training, Bedrock LLM services
  • Azure Credits: $25,200 for Azure OpenAI model training and deployment

These resources support the development of Bili’s RAG system and enable comparison of LLM capabilities across cloud platforms for sustainability data processing.

Student Involvement

More than 25 undergraduate and graduate students from five partner institutions have contributed to the project, gaining experience in:

  • Data engineering and pipeline development
  • Machine learning and NLP prototyping
  • Geospatial analysis and GIS data curation
  • User interface and UX design
  • Literature reviews and LLM evaluation
  • Community engagement and stakeholder outreach

Student Presentations

Students have presented project work at multiple venues:

  • GIS in the Rockies Conference - GIS data organization and sustainability data accessibility
  • NAIRR Pilot Inaugural Annual Meeting - BiliCore framework demonstration
  • 14th Annual Undergraduate Research Conference at MSU Denver - AI evaluation and LLM comparison frameworks

Media Coverage

The Sustainability Hub has been featured in MSU Denver’s RED Magazine:

“Questions about the environment? Bili may have answers” (January 2026)
