Systems and methods are described for attributing a primary causative agent for HVAC system usage being above or below an average, the HVAC system being controlled by a self-programming network-connected thermostat. Systems and method are also described interactively and graphically displaying schedule information to a user of an HVAC system controlled by a network-connected thermostat. The displayed information can include indications of the manner in which one or more setpoints was created or last modified. Historical HVAC performance information can also be displayed that can include details of certain energy-effecting events such as setpoint changes, adaptive recovery, as well as automatic and manually set non-occupancy modes.
