What is weather normalization?

Weather normalization in the hotel industry is a process used to adjust and standardize performance metrics, such as energy consumption, to account for variations in weather conditions. This allows hotels to accurately compare their performance against the target.

What is its purpose?

Weather normalization in PMI GoGreen allows you to compare your current year against the base year that you have set, removing any discrepancies due to weather differences to see if you are reaching your targets. Energy data from the current year is adjusted based on weather conditions in the base year as set in Goal distribution tool. Weather normalization can be activated by reaching out to your PMI contact or Support.

How is the data weather-normalized?

The data is sent to Energy Data IO, an external company specializing in energy management and weather normalization. They make the calculations and send the data back to us, where it is uploaded into the cockpit.

 

Navigation and view options

  1. Weather normalization is only available in the GoGreen Energy learning cockpit.
  2. Select the ‘Learning’ tab to view Weather normalization.
  3. The Weather normalization feature can be toggled on or off, depending on your view preference.
  4. Select the month to view by using the date selector. The current month will be selected by default.
  5. If Weather normalization is active on the page, only consumption values will be shown, as Cost and Co2 are not included in weather normalization.

When Weather normalization is activated, all data visible on the screen has been weather normalized, including hourly consumption.

  1. In the Composition table, you can compare your energy actuals to the target set and see the Variance. By comparing your target to the base year, you can see how you are progressing regardless of if last month was extra cold, by simulating the same weather conditions in the base year.
  2. The Biggest misalignments graph is populated with data when Weather normalization is activated.

Troubleshooting tips

This section provides additional troubleshooting advice for readers experiencing specific issues. While it’s packed with useful insights, you may skip it if you’re not facing any related problems.

What does GG stand for?

In PMI “GG” stands for GoGreen. This initiative focuses on sustainability and environmental responsibility. The abbreviation “GG” is commonly used by users when referring to sustainability tools and features within the full PMI software suite called GoGreen. For more about the GoGreen module view this article: GoGreen home overview.

GoGreen – “Green-Light” Routine

Every day

1. Banner is green? Great – data’s in. If red, chase the missing file.

2. Progress bar colour:

  • • Red bar → already over target → find the leak today.
    • Amber bar → slightly above forecast → ask the team what changed.
    • Green bar → on pace → no action.

3. Leave a one-line comment (“Boiler fault – gas up 18 % – engineer booked”).

4. Update your tasks (tick what’s done, add new fixes).

Every week

1. Scan the 12-month consumption chart

  • Look for any resource line that is creeping up – tackle it before budget season.

2. Export scores (Excel)

  • Send the file to Engineering and the F&B cost controller.
  • Agree who owns each amber/red variance.

3. Update the SMART forecast if operations changed

  • Big event cancelled? Enter a negative adjustment so the target resets and the team isn’t “over” for no reason.

4. Tidy the cockpit

  • Clear any lingering red banners (missing days).
  • Archive completed tasks so only live actions remain.

5. Celebrate wins

  • If the monthly bar is green and trending down, grab a screenshot and share it on the staff board – positive feedback drives future engagement.

Remember the order

  1. Data banner – proof the numbers are fresh.
  2. Progress bar – shows whether you are on pace.
  3. Comments – turn facts into context.
  4. Task-bank – turns context into action.

Goal Distribution Tool (GDT)

What is GDT? The GDT helps set long-term sustainability goals at the chain level, breaking them down into property-specific and monthly targets. These targets are visible in the GoGreen cockpit and Planning pages.

Goal Targets Not Displaying

  • Ensure that goals have been properly set and distributed at the chain level.
  • Check if the property has the required data, such as historical usage and occupancy figures.
  • Verify that the property’s activities and local weather conditions have been factored into the calculation.

Correct, change, register or add consumption

To register consumption, use the 'Add consumption' button within the cockpit. This allows for the input of new consumption values easily. If needing to update an entry, simply input the new value; PMI will override the previous entry with the new one, ensuring the latest data is always reflected. However, note that imported values cannot be overwritten in this manner. For tracking food waste specifically, use the "Production" category to enter total food waste figures accurately.
