Project Overview
BTU Engineers performed energy modeling for Chatsworth Courthouse located in Chatsworth, CA. The courthouse is approximately 340,600 sq.ft. ASHRAE Guideline 14 was used as a techinal guidance for statistical analysis of simulation error. BTU Engineers calibrated the baseline model to actual post-occupancy metered energy, to ±5% for monthly calibration and to ±10% for yearly calibration.
In addition, BTU Engineers performed various energy efficiency measures calculations, including both retrofit measures and retro-commissioning measures.
