Building management autonomous HVAC control using reinforcement learning with occupant feedback

A building management system comprising:

• a voice assist device;
• one or more processors;
• and
• one or more computer-readable storage media communicably coupled to the one or more processors having instructions stored thereon that, when executed by the one or more processors, cause the one or more processors to:
• define a state of a zone or space within a building;
• control an HVAC system to adjust a temperature of the zone or space corresponding to a first action;
• receive utterance data from the voice assist device located in the zone or space;
• analyze the utterance data to identify a sentiment relating to the temperature of the zone or space;
• calculate a reward based on the state, the first action, and the sentiment;
• determine a second action to adjust the temperature of the zone or space based on the reward;
• and
• control the HVAC system to adjust the temperature of the zone or space corresponding to the second action.
