Template 2 — Tenant Utility Data Request Email

Subject: Utility usage data request (kWh) — [Building], [Period]

Hi [Name],
We are compiling a verified utility usage dataset for [building/portfolio]. Please provide for [period]:
- billing period start/end dates
- kWh usage
- evidence (bill PDF or portal export)

If you prefer, you can authorize us to receive data directly from the utility.
Thanks,
[Name]

Template 3 — Escalation Ladder

Day 0: request
Day 7: reminder
Day 14: PM/leasing escalation
Day 21: lease clause notice (if available)
Day 30: renewal leverage escalation

Common pitfalls

  • ✗No tenant contact list
  • ✗No enforcement or escalation
  • ✗Not documenting allocations clearly
  • ✗Double counting with building-level Scope 2 reporting
