Case study: Creating a digital twin for smarter buildings
Helping a commercial office become audit-ready for ESG reporating and smarter asset management
The client occupied three floors of a multi-tenanted London office.
Building data was fragmented across multiple sources, with no structured view of systems, ownership, or energy cost allocation. With the Royal Institution of Chartered Surveyors ("RICS") environmental, social, and governance ("ESG") valuation mandate requiring auditable sustainability data, this lack of structure became a business risk.
The challenge
Building data fragmented across bills, invoices, facilities management reports, and spreadsheets
No clear view of systems, ownership, or landlord/tenant responsibilities
Limited ability to evidence energy usage or cost allocation
No Internet of Things ("IoT") infrastructure or real-time data visibility
Existing data not structured or audit-ready for valuation or reporting requirements
The solution
Structured all existing building data into a single, audit-ready data model
Mapped 14 building systems with stakeholder ownership and confidence scoring
Created a clear landlord vs tenant boundary model
Deployed wireless IoT sensors across three floors in one day with zero disruption
Captured real-time data across occupancy, climate, and energy usage
Integrated live sensor data directly into the digital twin for continuous insight
The results
Delivered a fully structured, auditable digital twin in 90 days
Clear visibility of energy ownership and cost allocation across stakeholders
Identified data gaps and targeted areas for improvement
Enabled evidence-based decisions on occupancy and energy efficiency
All data traceable to source, supporting RICS valuations, Global Real Estate Sustainability Benchmark and investor reporting
