  This paper describes the technical and conceptual development of the LuminLab
platform, an online tool that integrates a purpose-fit human-centric AI chatbot
and predictive energy model into a streamlined front-end that can rapidly
produce and discuss building retrofit plans in natural language. The platform
provides users with the ability to engage with a range of possible retrofit
pathways tailored to their individual budget and building needs on-demand.
Given the complicated and costly nature of building retrofit projects, which
rely on a variety of stakeholder groups with differing goals and incentives, we
feel that AI-powered tools such as this have the potential to pragmatically
de-silo knowledge, improve communication, and empower individual homeowners to
undertake incremental retrofit projects that might not happen otherwise.
