Shading system plays a significant role in reducing building energy demand. To analyse the performance of a shading system, traditional method is either conducting experimental tests for solar heat gain coefficient (SHGC) or through detailed energy simulation for energy saving during specific period.
ShadingPlus can tackle the calculation of SHGC and energy saving rate well. Through comparing with the results of simulation by other software and experiment, we can make a conclusion that ShadingPlus not only has convenient operation but also can get the accurate results in SHGC and energy saving rate.
For shading system, both fixed shading devices and movable shading devices are included. Current fixed shading devices included in the tool are as follows: overhang, fin, comprehensive shade, damper shade, horizontal flap shade and vertical flap shade.
Current fixed shading devices included in the tool are as follows: overhang, fin, comprehensive shade, damper shade, horizontal flap shade and vertical flap shade. For each type of fixed shading device, both location and dimension data are needed from the user to determine its position.
With EnergyPlus as its core simulation engine, ShadingPlus applies an optimal methodology to calculate SHGC. Moreover, annual energy saving calculation is also available with ShadingPlus which reflects shading system in a more realistic way. It is expected that the analysis for shading system can be greatly simplified using this tool.
Through comparing with the results of simulation by other software and experiment, we can make a conclusion that ShadingPlus not only has convenient operation but also can get the accurate results in SHGC and energy saving rate. ShadingPlus is a fast simulation programme for shading analysis based on EnergyPlus.

By comparing the radiation with and without the presence of the shading system, the shading coefficient of the system can be determined. These shading coefficients can be combined with the solar energy transmittance (g-value) of a glazing construction to give the total solar energy transmittance (gtot) on an hourly basis across a typical year.
