Energy Modelling & Building Energy Simulation
Detailed dynamic simulations predicting how buildings and districts consume energy under real-world conditions.
Energy Modelling Workflow — IES-VE
Geometry build → thermal zoning → fabric specification → Apache HVAC → annual simulation → EUI results.
Overview
Energy modelling is the foundation of high-performance building and development design. We develop detailed dynamic thermal simulations that predict how buildings and districts will consume energy under real-world conditions — accounting for climate, occupancy, building fabric, HVAC systems, controls, and district-level energy infrastructure.
Why It Matters
Design decisions made early have the greatest impact on a building’s lifetime energy consumption and carbon footprint. Without rigorous modelling, teams are designing blind — relying on rules of thumb that frequently underestimate consumption and oversize systems. Accurate energy models enable informed design trade-offs, de-risk certification pathways, and provide the evidence base for confident decision-making.
Our Approach
We build calibrated whole-building energy models from concept through to detailed design, using dynamic simulation to evaluate baseline vs. proposed performance, test energy conservation measures, and run sensitivity and parametric analyses. Our models are structured for transparency — clearly documented assumptions, reproducible inputs, and outputs that design teams can act on immediately. We work closely with architects and MEP engineers to ensure simulation outputs are integrated into the design process, not delivered as a standalone report that sits on a shelf.
