3.1.6 Modeling Space Temperature

The Rating Software shall contain a dynamic simulation of space temperature which accounts for:

• Dynamics in change in heating and cooling setpoint temperatures;
• Deadband between heating and cooling thermostat settings;
• Temperature drift in transition to setback or setup thermostat schedules;
• Temperature drift in periods when heating or cooling capability are scheduled off;
• Temperature drift when heating or cooling capability of the system is limited by heating or cooling capacity, air flow rate, or scheduled supply air temperature; and
• Indirectly conditioned thermal blocks, where the temperature is determined by internal loads, heat transfer through building envelope, and heat transfer between thermal blocks.
