# Find where energy is going. Decide what to change.

Understand hotel energy use in context. Investigate the gaps and prepare practical improvements for your team to review and approve.

## Understand the demand.

Heating, cooling, hot water and hotel facilities create different demands. Occupancy, opening hours and weather change them again.

The PHI model describes efficient use for this hotel. Review the gap alongside the inputs, assumptions and coverage.

## Follow the evidence.

A monthly total can show a difference from the model. Understanding its cause needs operating schedules, equipment information and site observations.

Where suitable interval readings exist, investigate time-of-day use. A detailed finding can still need a site check or additional metering.

## Get a decision ready.

Review the proposed work, its expected benefit, investment, disruption and assumptions. Your team decides what to approve and who is responsible.

Cadae prepares the investigation and proposed next steps. Your team reviews the evidence and approves the scope before any commitment.

## Check the result.

Compare suitable periods using an agreed measurement method. Account for weather, hotel activity and changes in what is measured.

PHI is published monthly. Completed work and accepted verification remain separate. Start with recent bills, activity figures and a description of the hotel.
