Public data on UK buildings is fragmented across dozens of registers. Each one tells part of the story. None of them tell the whole story. These case studies show what happens when you read them together.
Published
10 South Colonnade, Canary Wharf
Central government office hub — public estate · Built c.1991 · 65,451 m² whole-building demise
A flagship government HQ rated Band C on paper has operated at the bottom band, G, for two consecutive years — a three-band gap between design and operation, visible entirely in the public record.
The Mailbox, Birmingham
Mixed-use commercial — canalside conversion · Built 1990s · Multi-demise complex
An EPC Band G asset, five bands below the 2031 MEES threshold — with a refinancing signal already visible in the public record.
Quarry House
Government office — Grade II Listed · Built 1993 · 37,200 m²
EPC Band B on paper. Consuming more energy in 2024/25 than before its £5m decarbonisation programme. The EPC and DEC diverge by 82 points.
Royal Marsden Hospital
NHS Foundation Trust — Conservation Area · Built 1851 · 89,457 m² (Trust-wide)
EPC Band C. DEC Band F — deteriorating. CO₂e up 11% in year one of its net zero plan. A gas CHP system approaching the moment it becomes a carbon liability.
In Progress
Multi-academy trust estate
Secondary school estate — energy trajectory, fabric condition, climate risk
Local authority portfolio
50+ assets — cross-portfolio inference and risk prioritisation
Commercial office — Grade A
Central London — EPC vs DEC, MEES exposure, embodied carbon
About the analysis
Every case study draws on UK public data sources — EPC and DEC registers, Land Registry, Valuation Office, Historic England, planning history, satellite ground motion, LiDAR, flood hydrology, air quality, NHS registers, and socioeconomic data. No site visits. No proprietary data. No sensors.
The findings are reproducible. Every source is named. Every claim can be checked. Where the data is incomplete or ambiguous, that is stated explicitly. The confidence tier on each study reflects what the evidence actually supports — not what would make the most compelling story.
