1. A system to optimize energy usage comprising:
a transceiver configured to receive inputs from a detection unit, wherein the detection unit is configured to detect an extent of open state of a window associated with an enclosure and a presence of a user in proximity to the enclosure;
a processor communicatively coupled with the transceiver, wherein the processor is configured to:
obtain the inputs from the transceiver;
determine that the extent of open state is greater than a first predefined threshold for a predefined time duration and an absence of the user in proximity to the enclosure for the predefined time duration based on the inputs;
determine a first total time duration the extent of open state is greater than the first predefined threshold, responsive to a determination that the extent of open state is greater than the first predefined threshold for the predefined time duration and the user is not present in proximity to the enclosure;
calculate a first estimated energy loss associated with the enclosure based on the extent of open state and the first total time duration; and
output the first estimated energy loss.
