Core capabilities

What's inside.

Digital Building Registry
Digital Building Registry
Register every building with its location, typology, energy class, age and floor area. Group buildings into portfolios, search and filter them instantly, and import whole building stocks from CSV.
3D Map of Your Building Stock
3D Map of Your Building Stock
See your buildings on an interactive 3D globe in their urban context. Colour them by typology, energy class or energy use, and select buildings by drawing an area on the map.
Documents and Certificates
Documents & Certificates in One Place
Store EPCs, permits, floor plans, inspections and insurance documents for each building, with full version history. The platform alerts you before certificates expire.
Energy Performance
Energy Performance & Benchmarking
Track energy use and costs by energy source, with CO₂ emissions calculated automatically. Compare each building with national and peer averages, and follow trends over time.
Compliance Monitoring
Compliance Monitoring
See at a glance which buildings are compliant and which have missing or expired EPCs or missing energy data. Export ready-made compliance reports.
Renovation and Maintenance Planning
Renovation & Maintenance Planning
Get renovation recommendations and test what-if scenarios to see projected energy and CO₂ savings. Manage maintenance tasks and work orders from creation to sign-off.
BIM Viewer and Digital Twin
BIM Viewer & Digital Twin
Open IFC models directly in the browser and explore each element and its properties. Link IoT sensors to model elements to see temperature, humidity and CO₂ in the 3D model, live or as a replay of past data.
Smart Readiness Indicator score
Smart Readiness & Materials Passport
Assess buildings with the EU Smart Readiness Indicator (SRI) methodology and A–E rating. Record building materials with health and recyclability scores, and flag hazardous materials.

Analytics & Predictive Insights

Building health scores, anomaly detection, maintenance predictions and energy forecasts.

Collaboration & Reporting

Share buildings with controlled access, discuss them in comment threads, build custom dashboards, and schedule reports.

Secure & Multi-Tenant

Keep each organisation's data separate with role-based access for owners, facility managers, auditors and regulators, plus an audit log and GDPR tools.
