DesignBuilder is whole-building performance analysis software with an easy-to-use Graphical User Interface. Leading architects, engineers, and energy modelers across the world use DesignBuilder to quantify the impact of their design strategies on building performance. It helps in quickly developing comfortable and energy-efficient building designs, from concept to completion, that comply with building regulatory codes and certification schemes such as MOSTADAM, ASHRAE 90.1, and LEED.

DesignBuilder uses the simulation engine (EnergyPlus), developed and regularly upgraded by the US Department of Energy (USDOE) and it also uses the Radiance engine which provides reliable daylighting analysis.

Some of the following types of energy and comfort analysis can be done seamlessly on the building designs:

  • Comfort and overheating analysis
  • Daylighting effectiveness analysis
  • Solar shading analysis
  • Natural ventilation & passive design
  • Heating and cooling system design
  • Energy use and carbon emissions
  • Building internal and external CFD analysis

DesignBuilder enables you to:

  • Generate a wide range of outputs and reports to help you compare the performance of design alternatives.
  • Optimise the building at any stage of design and operation based on the client's objectives.
  • Model even complex buildings with the minimum of time and effort.
  • Import existing BIM and CAD design data to give you a head start with data entry.
  • Generate impressive rendered images and movies.
  • Simplify EnergyPlus thermal simulation.

On request, a free 30-day evaluation license of DesignBuilder can be provided for trial and training purposes.
