Before you start, it’s useful to have your details at hand. Here is a breakdown of what you need and where to find it.
Accommodation details
Your address is enough to get started: the platform uses it to retrieve the name, type, number of rooms, and your registration from Toerisme Vlaanderen. You can fill in the rest yourself:
- Surface area of the building in m².
- Percentage of private use. If you live in the building yourself, that part does not belong to your accommodation. Estimate it based on surface area: if you occupy 60 of the 200 m², that is 30%.
- Number of beds in addition to the number of rooms.
Occupancy data
Room-nights and person-nights over the full year, as a yearly total or per month. Sources: your Statbel declarations, your booking system, or your guest register. See Filling in occupancy.
Energy consumption
- Electricity in kWh per year, and separately your export to the grid if you have solar panels. Both can be found on Mijn Fluvius.
- Gas in kWh, as it appears on your annual statement. The platform does not accept the figure in cubic meters from your gas meter.
- Solar energy: the total yield of your panels, from your inverter’s app.
- Heat pump: the electricity consumption plus the SCOP of the device.
- Other sources: heating oil, LPG (propane or butane), wood or pellets, solar thermal, own wind turbine, hydrogen.
- Your EAN number. Found on your invoice and on the digital meter. Optional, but handy.
Water consumption
Your drinking water consumption in m³, from your water distributor’s statement, their customer portal, or your meter. If you have a rainwater tank or your own well with a meter, note those separately.
Optional data
Not required to start, but useful for a richer report:
| Data | Purpose |
|---|---|
| EAN number | Automatic check if you purchase green electricity |
| Website URL | Analysis of how you communicate about sustainability |
| Existing labels | Context in your report and label selection |
| Score on Booking.com or Google | Link between sustainability and guest experience |
If something is missing, start anyway. You can always add more later, and an incomplete year still provides a useful picture. Only publishing requires a complete year.
