I modeled window unit air conditioners but no electricity appears in the Cooling kWh/ year section?
In order to enter complete cooling system information in TREAT it is not enough to describe the cooling system on Heating/ Cooling screen. You must also specify which spaces are cooled on Thermostats screen by setting Is Area Cooled box to Yes for such spaces. If you enter cooling system but have not entered cooling setpoints on the Thermostats screen, TREAT warns you about the possibility of incomplete input when you start model calculations. It displays a warning message “At least one thermostat in the project is heating only.” In other words, if you have not specified cooling setpoint for any of the spaces in the project, TREAT assumes that air conditioner never operates. The criterion is used for the model and billing analysis period that is compared to that model.
