- Growing use of passive design to meet increasingly demanding energy standards.
Passive design lowers energy consumption but raises summer overheating risk (increased glazing, insulation and air tightness).
Simplified "compliance-based" modelling tools cannot evaluate overheating.
Understanding the trade-off between energy/carbon, cost and comfort using traditional modelling methods is difficult and timeconsuming when considering multiple design variables.
