Decisio – Decision making for smarter, faster, greener designPerformance expectations now shape building design and delivery. Decisio helps project teams explore realistic options early, visualize the trade-offs between energy, carbon, cost, and constructability, and align stakeholders around a clear path forward. This reduces late redesign and change orders, improves cost and schedule predictability, and protects design intent.
Decisio is CIMA+’s decision support service that combines energy modelling, operational and embodied carbon assessment, and cost analysis in one workflow, with a single point of accountability from concept to completion. Clients receive clear scenario comparisons, sensitivity insight that highlights what matters most, and practical recommendations they can act on to support high performance outcomes, sound financial decisions, and faster delivery.
Built on project specific energy models that reflect actual geometry and design inputs, Decisio provides credible results and decision grade insight at every stage.
How it works
Alignment
- A collaborative kickoff meeting establishes project goals, timeline, and performance targets, ensuring all stakeholders are aligned on direction and the design options to be modelled.
Empowerment
- Within weeks, Decisio evaluates thousands of practical combinations across architecture, envelope, mechanical systems, and lighting. Results are compared across energy, carbon, cost, and constructability. A follow-up meeting presents a sensitivity analysis showing how each choice affects the agreed targets, so the team can focus on the most effective solutions.
Accountability
- Decisio provides expert facilitation and a clear, actionable report that teams can rely on to make decisions and move forward.
“Decisio helps teams replace opinion with evidence early. It compares realistic scenarios across the building and its systems and highlights what actually moves the needle. The result is better performance decisions, stronger cost and schedule predictability, and fewer change orders.”

Integrated collaboration
Brings energy modelling, carbon assessment, and cost analysis into one coordinated workflow with a single point of accountability. Provides shared scenario visuals and decision ready reporting that improves coordination, reduces friction, and keeps stakeholders aligned from concept through delivery.
Financial clarity
Makes trade-offs visible early and highlights the few choices that drive the biggest impact. Helps teams prioritize cost effective strategies, reduce change order risk, and improve cost and schedule predictability.
Real data foundation
Built on project specific models that reflect actual geometry and design inputs, not generic assumptions. Produces credible, decision grade insight that teams can rely on at every stage.
Performance optimization
Tests thousands of realistic design and system combinations and compares them across energy, carbon, cost, and constructability. Supports faster decisions, fewer late pivots, and stronger outcomes with less rework.
