DesignBuilder provides a graphical, integrated experience to help predict energy efficiency and occupant comfort in buildings.

A Visualisation engine displays sun penetration and sun path diagrams and allows a designer to visually and interactively test the effectiveness of shading strategies.

DesignBuilder incorporates EnergyPlus, the award-winning, dynamic, whole-building simulation engine developed and maintained by the US Department of Energy (USDOE).  EnergyPlus predicts building greenhouse gas emissions and occupant thermal comfort.  It is one of a very few simulation engines that integrates heat and mass balance calculations, and can accurately predict free-floating temperatures in Naturally Ventilated spaces.

DesignBuilder’s Detailed Heating, Ventilation and Air-Conditioning¬† (HVAC) system Graphic User Interface (GUI) makes it easy to model complex, customised, HVAC plant and systems in EnergyPlus.

The Radiance engine provides reliable daylighting analysis.

An integrated CFD engine allows for analysis of airflow (and other parameters) within the building and between buildings.

DesignBuilder is sold and supported by DesignBuilder Software Australia, the exclusive reseller to customers in Australia and India.
