50% Cost Reduction and Proven CO₂ Savings — Audit-Ready Data from Existing Meters
A leading building management firm in Japan eliminated manual meter reading across its building portfolio, delivering 50% running cost savings, tens of percent CO₂ reduction, and positive impact on sustainability management — while freeing senior engineers to focus on workforce development.
The Challenge
This firm manages building lifecycle operations for a major construction group — HVAC, electrical, and fire-safety systems across a growing portfolio. Many properties required on-site meter reading visits, each involving entry permission coordination with building owners and tenants, travel scheduling, and manual data recording. Growing staff shortages made this routine increasingly unsustainable — consuming time that senior engineers needed for technical skill transfer, a process that takes up to five years per new engineer.
The Solution
After a hands-on trial confirmed reliable data acquisition and a practical user interface, the firm built the internal business case across three dimensions — people, money, and time — and deployed VeriReader on existing meters. Automated readings replaced every manual site visit, with structured energy data delivered to a centralized management view.
The Results
- 50% reduction in running costs
- Vehicle travel distance reduced by hundreds of kilometers
- CO₂ emissions reduced by tens of percent
- Complete elimination of meter-reading site visits
- Positive impact on sustainability management
- Time reclaimed for technical skill transfer to next-generation engineers
Field staff response: "They're asking us to deploy it across all properties as quickly as possible."
The structured energy data now flowing from the firm's legacy meters provides a traceable Scope 1 and Scope 2 foundation for sustainability reporting — delivered as a built-in outcome of solving an operational problem, not as a separate ESG investment.
"Running costs were reduced by 50%, exactly as we projected. On top of that, total vehicle travel distance decreased by hundreds of kilometers, and CO₂ emissions were reduced by tens of percent — all contributing positively to the sustainability management goals we are pursuing."
