PJD Holdings Plc engaged D3 to upgrade the energy monitoring infrastructure at Express Buildings, a multi-tenanted office complex in Manchester city centre. The existing metering systems were disparate and outdated, limiting visibility into energy consumption and creating challenges around accurate tenant recharge.

Automated Metering & Billing

D3 adopted and upgraded the existing infrastructure, standardising data capture and deploying the D3 Cloud platform to automate tenant billing, improve accuracy, and provide tenants with direct visibility of their energy usage. The solution delivered rapid operational improvements and a return on investment in under 12 months.
The Challenge
Express Buildings comprised multiple tenants with legacy metering infrastructure that had evolved over time. The systems lacked consistency, reliability, and centralised visibility, making tenant recharge complex and time-consuming.
Key challenges included:
Disparate and outdated metering systems
Limited visibility into tenant consumption
Manual and inefficient recharge processes
Risk of inaccurate billing
No tenant access to usage data
Lack of centralised reporting
The client required a fast, cost-effective upgrade without major disruption to tenants.
The Solution
D3 adopted the existing infrastructure and upgraded the metering and communications systems to deliver accurate, standardised data across the building.
The solution included:
Adoption of existing meters where viable
Upgrade of communications infrastructure
Integration into D3 Cloud platform
Automated tenant billing engine
MID-aligned data capture and validation
Dedicated tenant portal logins
Tenant reporting and consumption visibility
This enabled accurate and automated tenant recharge while improving transparency for occupiers.
Deployment
D3 delivered the project through a rapid retrofit approach:
Site audit and infrastructure assessment
Meter and communications upgrades
System commissioning
D3 Cloud onboarding
Tenant billing configuration
Tenant portal access setup
The entire deployment was completed in under one month.
Results
The upgraded system transformed energy management at Express Buildings, enabling accurate billing and improved operational efficiency.
Tenants now benefit from direct visibility of their consumption through the D3 portal, where they can generate reports and better understand their energy usage and environmental footprint.
The property team now benefits from automated billing, improved accuracy, and reduced administrative overhead.
