1. A method for identifying maintenance tasks in a building that includes a Building Management System (BMS), wherein the BMS system of the building includes one or more of an HVAC system, a security system, a lighting system, a fire system and an access control system, the method comprising:
retrieving an ontology model of the BMS, wherein the ontology models defines contextual information for one or more BMS components of the BMS including a particular BMS component, the contextual information including a plurality of properties and one or more relationships defined between two or more of the properties;
retrieving one or more system configuration parameters of the BMS, wherein the system configuration parameters include one or more system algorithm settings and one or more system operational parameters;
sensing one or more environmental conditions in the building;
capturing a plurality of images over time of the particular BMS component of the BMS system using an image capture device, wherein the particular BMS component includes one of an HVAC system component, a security system component, a lighting system component, a fire system component and an access control system component;
determining when the particular BMS component needs maintenance based at least in part on:
one or more of the environmental conditions in the building;
one or more of the plurality of images of the particular BMS component;
the ontology model; and
one or more of the system configuration parameters;
sending a maintenance request to service the particular BMS component when the particular BMS component is determined to need maintenance.
