The webinar explains how RETScreen can support energy management, energy audits, and measurement & verification (M&V), especially using IPMVP standards.
Key points:
Energy efficiency savings must be verified credibly, not just estimated.
A case study of 28 commercial office buildings showed 16 million kWh saved, doubling the original 5% target to 11%.
RETScreen helped manage complex M&V work, especially during COVID disruptions, using non-routine event adjustments.
Compared with Excel, RETScreen offers more consistency, built-in QA/QC, easier sharing, portfolio analysis, and stronger M&V tools.
The speakers emphasized CUSUM analysis as a powerful way to detect performance changes, billing errors, equipment faults, and sustained savings.
Several real examples showed RETScreen identifying issues such as utility billing mistakes, passing valves, poor boiler controls, schedule improvements, and water savings.
The main message: combine people, process, and tools to make energy efficiency measurable, credible, and actionable..
