You need to provide us with 3 years of monthly consumption of the building, on each energy used (electricity, gas or district heating), at the building level (main metering).

The metering information may come from either:

• Your main utility meters
• Energy bills
• Your metering system

You don’t have 3 years history for one energy?

• Please make sure you can provide us with 1 year of clean data of monthly consumption. If the data is correct, we are able to set your reference
• If the heating data is not remotely clean (ex.: fuel index) you can run an “electricity only” contest (even if your efforts will take on all the energy, including heating, the percentage we will calculate will only take the electricity into account.)

Multi-tenant building:

• Best case: you are able to consolidate the consumption data of your tenants in one electricity and heating monthly consumption
• Frequent case: you have all of the consumption of the biggest tenants, but some minor tenants are independent and you won’t be able to collect the data (ex.: shops at office building ground floor). These may be overlooked, even if the heating is distributed to them, as the main users’ efforts will make up for these. The perimeter of metering, however, must not change during the contest.
• If submetering is well in place, you can run a fraction of the building as a candidate.
• Tenant as candidate:
  • Mono tenant: easy case
  • Tenants within a multi-tenant activity can run the contest (ex. in the past editions, retail shops in a commercial centre), two situations:
    • Submetering allows to separate tenant consumption on all energies
    • Submetering allows to run the contest on electricity (event if the effort will also take care of heating)

Whatever your choice, the perimeter of metering shall be the same during the contest (historical data, contest year)
