REM Savings Calculator

Room Energy Management
Estimate your room energy consumption, potential savings and investment payback.

1. Property details

24-hour operation scenario: Without REM, all selected loads are assumed to operate throughout the day. With REM, they switch off during the selected vacancy period and remain on for the remaining hours. Refrigerators are excluded.

2. Devices in one room

Air conditioning

Spotlights and bulbs

LED strips / concealed lighting

Television

Other electrical devices

You may add extractor fans, heated towel rails, mirror heaters or standby loads. Only include loads that can remain on in an empty room. Do not include short-use appliances such as kettles or hair dryers in this 24-hour scenario.

3. Room energy consumption without REM

6. Potential reduction in transformer load

Combined power of the loads switched off in empty rooms.
Daily energy reduction with REM

Reducing the electrical load may help reduce thermal stress on the transformer. Verified spare capacity may enable investments previously limited by insufficient transformer capacity.
