1. A heating, ventilation, and air conditioning (HVAC) system comprising:
an indoor humidity sensor positioned and configured to measure an indoor humidity value of air in an enclosed space;
an outdoor humidity sensor positioned and configured to measure an outdoor humidity value of outdoor air; and
a controller communicatively coupled to the indoor humidity sensor and the outdoor humidity sensor, wherein the controller comprises a processor configured to:
during an initial period of time, store a record of an energy demand of the HVAC system that corresponds to an amount of energy used to operate the HVAC system;
for a first time point of a future time period that occurs after the initial period of time, receive a first indoor humidity value measured by the indoor humidity sensor and a first outdoor humidity value measured by the outdoor humidity sensor;
for the future time period, determine an anticipated energy demand of the HVAC system, based at least in part on the first indoor humidity value, the first outdoor humidity value, and the record of the energy demand during the initial period of time;
recursively determine, for each of a plurality of time points within the future time period following the first time point, an anticipated indoor humidity value using the anticipated energy demand for the future time period; and
cause the HVAC system to operate based at least in part on the anticipated indoor humidity value.
