Description
The Energy-Driven Retrofit & Investment Prioritisation service provides the Municipality of Athens with a systematic, data-driven framework for prioritising energy-related capital investments across its public building portfolio. It replaces ad hoc decision-making with a rigorous, continuously updated investment ranking grounded in actual consumption data, peer benchmarking, and waste persistence analysis. The output is a prioritised investment register that identifies which buildings offer the greatest energy saving potential and are best positioned to secure external co-funding.

Business Need
Municipal budgets for building improvement are finite and contested. Without data-driven prioritisation, decisions about which buildings to retrofit are typically made on the basis of visible deterioration rather than energy performance evidence. The service enables smarter allocation of both municipal capital and grant resources by surfacing the buildings where the data most strongly indicates underperformance relative to peers, providing a structured, evidence-based starting point for facility managers and finance teams.
Key Performance Indicators
Recoverable saving estimate accuracy (MAPE): deviation between pre-intervention estimate and post-intervention verified saving
Priority ranking stability: consistency of rankings across consecutive calculation cycles
Portfolio-level scenario accuracy: aggregate saving potential estimates vs. realised outcomes
Coverage tier analysis: cumulative estimated savings across different priority tiers
Data Provided
Weather-normalised annual electricity consumption per building
Peer-group benchmarking data by building use category and floor area
Cumulative waste register from the Anomaly & Waste Intelligence service
Building metadata including use category, floor area, and construction era
Prioritised investment register with recoverable saving estimates
