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
