Building management system with building equipment service and parts recommendations

This invention describes a system that helps manage building equipment by using an advanced AI called a large language model (LLM). The LLM is specifically trained on building-related information, such as equipment types and their performance. Users interact with a guided interface to describe a problem or need for a specific piece of equipment, and the LLM then provides recommendations for service, parts, or technical assistance related to conditions like temperature or resource use.
