DesignBuilder: Advanced Tools to Optimise Performance and Impact

DesignBuilder is a powerful, all-in-one simulation tool that goes beyond standard modelling. Advanced features like parametric analysis, optimisation (using genetic algorithms), runtime scripting, and flexible detailed HVAC modelling, help you deliver better results – faster and more cost-effectively. With a single DesignBuilder model, you can:

• Optimise compliance ratings for UK and Ireland Certification (EPC, Part L, TM52/59/Part O etc.).
• Optimise real-world performance throughout design stages, modelling to standards like TM54, NABERS UK and DfP, BREEAM, LEED, and ASHRAE 209.
• Optimise operational efficiency in existing buildings using TM63, ASHRAE Guideline 14, and IPMVP.

This session will guide you through each modelling stage – compliance, design, and operation – showing how DesignBuilder’s high-productivity tools enable better decisions and outcomes. You’ll also get access to free resources to help you get started.
