The energy modeling landscape has undergone significant changes with ASHRAE Standard 90.1-2016, particularly in how a building's performance is measured. Previously, the Appendix G baseline was based on prescriptive requirements, but now it is set to ASHRAE 90.1-2004. The Performance Cost Index (PCI) baseline is scaled from 0 to 1, where a BPF (Building Performance Factor) of 1 represents ASHRAE 90.1-2004, and a BPF of 0 signifies net zero.
The Challenge of PCI Calculations
PCI calculations are complex and require substantial effort. Given that energy modeling often involves repeated processes, there's a critical need to automate these calculations to streamline workflow efficiency. Below is an example of PCI calculations, excerpted from the ANSI/ASHRAE/IES Standard 90.1-2016 Performance Rating Method Reference Manual.
