Cooling and heating methodology and systems

One or more non-transitory computer readable media comprising instructions which, when executed by one or more hardware processors, causes performance of operations comprising:

• detecting a current outdoor temperature at a location of a first structure and a second structure comprised in a building, wherein the first structure comprises a first window, and wherein the second structure comprises a second window;
• detecting a first current indoor temperature inside the first structure;
• detecting a first target indoor temperature for the first structure;
• based on the current outdoor temperature, the first current indoor temperature, and the first target indoor temperature, determining that a first window opening criteria is met;
• responsive to determining that the first window opening criteria has been met:
• instructing a first window control mechanism to modify a state of the first window from (a) a closed position that prevents airflow through the first window between outdoor space external to the building and the first structure to (b) an open position that allows for airflow through the first window between the outdoor space external to the building and the first structure;
• detecting a second current indoor temperature inside the second structure;
• detecting a second target indoor temperature for the second structure, wherein the second target indoor temperature for the second structure is different than the first target indoor temperature for the first structure;
• based on the current outdoor temperature, the second current indoor temperature, and the second target indoor temperature, determining that a second window opening criteria is not met;
• responsive to determining that the second window opening criteria has not been met:
• maintaining the second window in a closed position by refraining from instructing a second window control mechanism to modify a state of the second window from (a) a closed position that prevents airflow through the second window between the outdoor space external to the building and the second structure to (b) an open position that allows for airflow through the second window between outdoor space external to the building and the second structure.
