BPI-2400 Calibration Made Simple: Practical Insights for Better Audits

Join us for a deep dive into the fundamentals and practical applications of the BPI-2400 standard, a cornerstone of calibrated energy modeling and a key requirement for IRA HOMES programs. This session will empower attendees with:
- A Practical Overview of BPI-2400: Understand utility regression, calibration targets, input constraints, and why parametric input-based calibration outperforms output-based methods.
- Best Practices for Accuracy: Learn how detailed data gathering and calibrated auditing ensure precise energy savings projections while avoiding common pitfalls.
- Insights from Research: Explore findings from a large Lawrence Berkeley National Laboratory study verifying the accuracy and reliability of BPI-2400 calibrated audits.
- Real-World Examples: Review specific audits that demonstrate how to address challenges such as utility bill errors, overlooked end uses, and inaccurate geometry.
- Identifying and Addressing Known Unknowns: Tackle uncertainties and mitigating factors like temperature stratification, duct leakage, and heat regain that models may not directly account for.
- Lessons from the Field: See how these practices have performed in the real world, with case studies showcasing results and lessons learned from IRA HOMES programs.

This session will provide practical guidance and lessons learned from the field, ensuring contractors and program administrators can apply calibrated auditing with confidence and precision.
