Building Energy Intelligence

Map. Model.
Decarbonise.

An integrated platform for EPC & DEC certificate analysis, 3D building extrusion from OpenStreetMap data, and thermal energy modelling — helping you understand and reduce building carbon emissions across the UK.

End-to-end building energy analysis

From certificate data to 3D visualisation and carbon intensity modelling — everything you need in one system.

EPC & DEC Retrieval

Automated gathering of Energy Performance Certificates and Display Energy Certificates for domestic and non-domestic buildings, with full rating history tracking.

3D Building Extrusion

Transforms OpenStreetMap footprint data into 3D building models with height, floor area, perimeter and volume metrics for every structure.

Thermal Modelling

Simulate building energy profiles across multiple scenarios — incorporating solar PV generation, battery storage state-of-charge, and grid electricity consumption.

Carbon Intensity Analysis

Compare grid carbon intensity across years with half-hourly resolution. Track the UK's decarbonisation trajectory and model the impact on your building portfolio.

Spatial Mapping

Interactive map layers with EPC rating colour-coding, local authority filtering, and portfolio management. Overlay 3D buildings for a complete spatial view.

Portfolio Management

Build and manage portfolios of buildings across local authorities. Track EPC rating changes over time and flag properties due for reassessment.

See it in action

Explore EPC ratings across local authorities, drill into individual buildings, and visualise energy profiles at scale.

The grid is getting cleaner

UK grid carbon intensity has dropped dramatically. Our modelling captures this shift at half-hourly granularity.

~280 2018
~240 2019
~200 2020
~185 2021
~165 2022
~135 2023
~104 2024

2018 vs 2024

Grid carbon intensity dropped from roughly 280 to 104 gCO₂/kWh in summer months — a transformation driven by renewable energy expansion. Our platform tracks this at half-hourly intervals to model real-world building emissions.
