Calculation of heat flows through wall, floors and roofs is an essential element of building simulation, prediction of energy demands and related carbon emissions. Despite the proliferation of building energy simulation software tools, the representation of these basic elements is one-dimensional so that the true effects of wall junctions, frames and ground contact are poorly represented.
In recent years Building Information Modelling (BIM) has advanced the geometric representation of construction components significantly so that it should be possible to advance the state of the art in energy simulation. However, this has not happened. This project will seek to take advantage of the improved geometrical representation of building components in BIM data. The aim will be to improve prediction of energy flows through application of a recently developed heat transfer calculation method known as ‘Dynamic Thermal Networks’. This allows accurate and fast calculation of three-dimensional heat flows. The project will be an opportunity to work at the forefront of advanced building energy simulation development.
