EPCFlow — Digital Energy Performance Certificate Platform for EU Property Transactions

The Problem

The recast Energy Performance of Buildings Directive (EPBD), which entered into force May 28, 2024, requires all EU member states to transpose new EPC rules into national law by May 29, 2026 — barely two months from now. The directive mandates:

1. Harmonized EPC calculation methodologies across the EU
2. Digital EPCs that must be entered into national databases
3. New EPC classes based on updated energy performance metrics
4. Mandatory EPCs for all new buildings, deep renovations, sales, rentals, and public buildings
5. Whole-Life Carbon reporting for new buildings over 1,000m² from 2028

The current state of EPC issuance across Europe is chaotic. Each country has its own legacy system — many dating back to 2002 when the original EPBD was enacted. Assessors use country-specific desktop software (often Windows-only), PDF-based workflows, and manual data entry into national databases. There is no modern, cloud-based, pan-European platform that supports the new harmonized methodology.

For energy assessors, the transposition means their existing tools may become non-compliant. For property professionals and managers, tracking EPC validity across portfolios spanning multiple countries is a spreadsheet nightmare.
