QUICK SUSTAINABLE ARCHITECTURE DESIGN
Design with creativity. Decide with data.
QSAD with Oli.ai transforms your earliest massing studies into defensible, client-ready sustainability decisions — balancing energy, cost, and embodied carbon from day one.
80% of building performance is decided before sustainability tools are available.
In the sketch design phase, architects/engineers/developers rely on experience and intuition — and rightly so. That expertise is irreplaceable.
But when it comes to balancing energy, cost, and embodied carbon simultaneously, even the most experienced architect is working without instruments. The tools that could help arrive too late, after the most impactful decisions are already locked in.
Sustainability-informed decisions,
right when they still count.
QSAD puts physics-based energy analysis and EPD carbon data into the sketch phase — the only moment when your decisions still have real impact.
No waiting for a consultant or a full model. Every geometry change updates energy, cost, and carbon instantly — so you explore more options before anything gets locked in.
QSAD is built for architects at sketch stage — not for QS or energy engineers. You get expert-grade numbers without needing to be one, and without changing how you work.
Draw your massing once. Get energy performance, lifecycle cost, and embodied carbon simultaneously — from the same geometry, in the same tool, with no duplication of effort.
QSAD's AI engine doesn't just show numbers — it surfaces the highest-impact trade-offs and explains them in plain language, so you can act on them and defend your decisions to clients.
AI-poweredConvince clients.
Win competitions.
The same analysis that guides your design becomes your evidence. Present energy performance, cost rationale, and carbon targets with the rigour clients and competition judges expect — generated automatically, at sketch stage.
Schedule a demo →One platform. Three critical lenses.
QSAD balances all three simultaneously, so you never trade one for another without knowing it.
Heating Energy Demand
kWh/m²·yrUnderstand your building's thermal performance against EPB and Passive House benchmarks from the earliest geometry input.
Initial Financial Footprint
See the full cost implications of every design decision in real time — no quantity surveyor needed at concept stage.
Material Carbon Footprint
kg CO₂eqTrack the full material carbon footprint of your building as you design, not as an afterthought at the end.
Oli.ai. Sustainability intelligence
built for architecture.
Complex trade-offs between energy, cost, and carbon are hard to reason through alone. Oli.ai gives you the comprehensive picture — instantly — so your decisions are informed, defensible, and yours.
Scenario Optimisation — Explore entire design spaces automatically.
Oli.ai generates multiple optimised design scenarios — cost-optimised, energy-optimised, and carbon-optimised — so you can compare trade-offs in seconds, not days.
Analysis and Explanation — Understand your results instantly.
Oli.ai interprets your performance metrics, highlights what is driving your numbers, and recommends actionable improvements — all in plain language, no expertise required.
From first sketch to informed
decision in minutes.
Define your building
Enter basic geometry, location, orientation, and materials. QSAD instantly computes your baseline energy, cost, and embodied carbon.
Test your ideas
Explore design options in line with your creativity — adjust window ratios, materials, and building geometry and see the impact on all three metrics in real time.
Save and compare
Save your designs side by side and compare their performance metrics at a glance.
Let Oli.ai optimise
Oli.ai generates a range of design scenarios, each balanced and optimised across all three performance metrics simultaneously.
Understand trade-offs and export
Oli.ai analyses the scenarios, explains the key performance drivers in plain language, and exports results ready for reporting or client presentations.
Built for everyone who
shapes buildings.
Design sustainably from the first sketch.
Make informed sustainability decisions at concept stage without needing a specialist. Present energy, cost, and carbon performance to clients from day one.
View For Architects →Validate assumptions early.
Align structural and energy performance with carbon and cost targets before detailed design begins. Catch conflicts early, when fixing them is still cheap.
Assess more projects in less time.
Run rapid assessments across multiple design options. Benchmark against EPB and Passive House standards from a single platform, without switching tools.
Embed sustainability into your own tools.
Access QSAD's full calculation engine via API. Integrate triple-metric performance analysis directly into your workflows, platforms, and products.
