What's inside

1. The 5 levers, broken down — each with its detection method, the action taken on site, the avoidable MWh per year and the investment required.

2. Technical architecture — how it was integrated on top of the existing infrastructure, which systems were connected, and how real consumption was reconstructed with 93–95% accuracy.

3. Benchmarks by vertical — which levers apply to hotels, retail, facility management and multi-site operations, with expected savings by type.

4. Multi-site scaling criteria — how the methodology replicates from one site to a portfolio of 10, 40 or 80 assets: ROI prioritization, estimated rollout speed per site, and how marginal cost falls as you scale.
