Comprehensive Pliant Permissive Priority Optimization (C3PO)
This case study aims to build a community emulator based on a real-world Net-Zero Energy Community located in Anna Maria Island, FL, US. The community has onsite PV panels and reached net-zero energy in 2014. This emulator has seven submodules; namely, power grid, PV system, weather, schedule, ground-source heat pump system, domestic hot water system, and building loads. The PV system and building loads have been validated against measured data. The schedule module has the function of dynamic prediction of occupant presence. Based on this, in the HVAC system, we implemented occupancy-based thermostat control. Also, the prediction of significant building loads is correlated with occupancy status.
