Embed sustainability
into your own tools.
Access QSAD's full triple-metric engine — energy demand, construction cost, and carbon — via a single REST API. Build smarter platforms, automate compliance checks, and give your users sustainability intelligence from day one.

Three steps. Real results.
No specialist setup. No custom schema required. Send building data in your format — receive structured performance metrics in milliseconds.
Send a building description
POST your building data in your own format and schema. Location, use type, floor area, structure, orientation — whatever you have. QSAD adapts to your data model.
QSAD calculates in milliseconds
Our engine simultaneously computes energy demand, construction cost, and embodied carbon — three metrics in a single API call, with sub-second response times.
Receive structured results
Receive clean, structured results — and display them however you want in your own product.
Built for software products.
Plug into any stack
Standard REST API with JSON. No proprietary SDK required. Works with any language, any framework — if it can make an HTTP request, it can use QSAD.
Fast & scalable
Sub-second response times, designed for real-time UI feedback. Built for software products that need performance at scale — not one-off exports.
Stateless & secure
We don't store your users' project data. Every request is processed and discarded. Full GDPR compliance, EU infrastructure only.
Modular by design
Pick the calculations, metrics, and AI features your product needs. Use only energy, or the full triple-metric engine — the API adapts to your scope without unnecessary overhead.
