Whole building energy simulation software updated for architects and engineers

DesignBuilder Packages for Engineers uses CFD to calculate and view airflow and 3D temperature distribution

Version 4 of the whole building energy simulation program ‘DesignBuilder’ is said to add a substantial set of new features and improvements focused on the different but overlapping needs of architects and engineers.

DesignBuilder Packages for Architects is used at the early design stages to help meet performance targets by providing accurate and reliable energy and daylighting performance data. The architectural simulation packages allow architects to link with BIM tools, analyse solar shading, maximise the use of renewable technologies and test façade options in a single software program.

DesignBuilder Packages for Engineers consists of an integrated set of tools to assist with the integration of mechanical systems within sustainable buildings design. Various design scenarios for HVAC systems and controls, facades, lighting, and renewable technologies can be evaluated. Using drag and drop air and water components, HVAC systems can also be constructed within DesignBuilder from scratch.

All DesignBuilder packages are said to provide sensitivity analyses at the click of a button. High quality technical and rendered outputs help communicate findings to clients. Key performance indicators such as energy consumption, carbon emissions, thermal comfort, daylight availability and cost can be provided throughout the design process in both naturally ventilated and air-conditioned buildings.

“The new functionality provided by version 4 really is a step-change in DesignBuilder’s energy and comfort modelling capabilities,” said Dr. Andy Tindale, founder and CEO of DesignBuilder. “Some major improvements to the modeller further enhance our existing strengths in the ability to create and edit geometry quickly and easily. The improved BIM import; enhanced LEED and ASHRAE 90.1 capability; new HVAC systems such as ground source heat pumps; tariff analysis; simulation manager for running parallel simulations and optimisation for multi-objective cost benefit analysis have helped to strengthen our position as the leading interface to EnergyPlus.”
