Buildings are no longer just consumers of energy. With solar generation, storage and shared infrastructure, they increasingly produce and exchange energy too. That raises a question of trust: in a multi-party arrangement, whose meter do you believe? Blockchain offers one answer.
The trust problem
When a landlord, several tenants and perhaps a grid or a neighbouring building all generate, store and consume energy, the records of who did what have real financial weight. A shared, tamper-evident ledger means no single party can quietly alter them.
Where it can help
- Transparent sub-metering across tenants and owners
- Verifiable records for energy sharing and settlement
- Peer-to-peer energy trading between parties
- Trusted data for sustainability and carbon reporting
- Automated settlement through smart contracts
A realistic view
This is an emerging area, and blockchain is not required for every building, a single trusted operator with good metering often needs none. Its value appears specifically where multiple parties must share records they all trust without a single controller.
Built on solid metering
Any such system still rests on accurate, secure metering. The ledger records the truth; the meters must capture it correctly in the first place.
