M&V and EPC components

The Measuring and Verification (M&V) component plays a key role in supporting Energy Performance Contracts (EPCs). It ensures transparency and builds trust between Energy Service Companies (ESCOs) and building owners or tenants by providing accurate monitoring of energy consumption and contract performance. This component enables users to understand how their energy bills are calculated and verify that promised energy savings are being delivered.

The M&V process follows a structured methodology that includes four phases: establishing contract rules, calculating energy savings, applying a bonus/malus model based on results, and computing the final bill. These calculations use real-time data such as external temperature and energy usage, pulled from a centralized Data Sovereignty Layer (DSL) and a data analytics intermediary. The system allows ESCOs to upload contract details, often using their standard Excel formats, to initiate the process.

A distinctive feature of this implementation is its use of Zero-Knowledge Proofs (ZKPs) and blockchain technology. Each time a bill is generated, a ZKP is created to cryptographically prove that the savings and costs have been calculated correctly, without exposing sensitive data. A smart contract on the Ethereum blockchain verifies the proof, and the outcome is permanently recorded on-chain. This enables a highly trustworthy and privacy-preserving verification process that can be publicly audited.

The platform includes a web application primarily intended for ESCOs to manage EPCs and contracts, but it is also accessible to building managers to view their bills. A visual, user-friendly interface replaces the traditional use of static PDFs and offers improved engagement. Additionally, an “EPC Designer” tool allows ESCOs to model pre-renovation consumption baselines based on external temperature data, streamlining and automating what was previously a manual task.
