Your building data is scattered.
ninezero collects it all.
Vendor portals, BMS exports, manual spreadsheets — building energy data lives in dozens of disconnected systems. ninezero connects them into a single, structured, queryable layer you control.
Connect to Any Data Source
Pre-built adapters for utilities, DataHubs, and energy providers across Europe. Energinet DataHub, ENTSO-E, Aalborg Forsyning — or connect any source via MQTT, REST, or webhooks. We handle the protocol differences so you don't have to.
Your utility has an API but no ninezero adapter? We'll build and deploy it within one week, guaranteed.
Built for Consumption Data
Purpose-built time-series datawarehouse optimized for utility data. Columnar compression, partitioned by time, designed for the read patterns that matter: aggregation across meters, buildings, and time ranges. Handles billions of measurements without breaking a sweat.
Semantically Classified, Not Just Stored
Every entity in ninezero — organizations, sites, buildings, meters — is classified with a Brick Schema URI. This isn't just metadata. It's a semantic graph that enables RDF/OWL export, cross-system interoperability, and EU regulatory compliance out of the box.

}Agent-Ready API
A high-performance REST API designed for both human developers and AI agents. Structured JSON responses with Brick URI references, consistent schemas, and semantic entity relationships make it natural for LLM-based agents to reason over building portfolios — no prompt engineering required.
The same API that powers your dashboards is available to every tool in your stack.
Portable by Design
Deploy ninezero as a lightweight datawarehouse on-premise or in the cloud, under your full control. Standard formats, open APIs, complete data export at any time. Your data never gets locked in.
Developed and operated from Aarhus, Denmark. Deploy within the EU using European cloud providers like UpCloud and Scaleway — keeping your data in-region and under your control.
