DesignBuilder is a state-of-the-art software tool for checking building
energy, CO2, lighting and comfort performance. Developed to simplify the
process of building simulation, DesignBuilder allows you to rapidly compare
the function and performance of building designs and deliver results on
time and on budget.
DesignBuilder combines rapid building modelling and ease of use with state
of the art dynamic energy simulation.
DesignBuilder is easy to use. Its innovative productivity features allow
even complex buildings to be modelled rapidly by non-expert users.
DesignBuilder is the first comprehensive user interface to the EnergyPlus
dynamic thermal simulation engine.
