3.1 Building description 62 EnergyPlus 3-D model of the building In the EneryPlus-System, heat and mass balance calculations are conducted for the separate control volumes called zones. The modelling of heat transfer for building components includes conduction, natural/forced convection and long/short wave radiation. In order to achieve a good accuracy rate of calculations, a detailed geometric model of the building, based on the architectural plans and specifications, is created in a threedimensional Cartesian right hand coordinate system (X-axis points east, Y-axis points north, Z-axis points up). Rendering views of 3-D models with shading detached and attached surfaces are presented in Fig. 3.9 and Fig. 3.10. Fig. 3.9: The complete view of the house without movable protection shield.
3.1 Building description 63 In order to determine solar heat gains it is necessary to calculate shading and sunlit areas. In the EnergyPlus-System a shadow algorithm is based on the Groth and Lokmanhekim (1969) coordinate transformation method and the Walton (1983) shadow overlap scheme. Two houses (house number 146 and 150) and two rows of trees are used as detached external surfaces to generate shadows. The houses are not transparent for solar radiation but the trees have seasonally changed their diffuse properties. Fig. 3.10: The complete model view with movable protection shields mounted on a rail construction on the level of the building façade and detached shading objects. The tested building is split into 21 isothermal zones. The zone is defined as an air volume at a uniform temperature plus all the heat transfer and heat storage surfaces bounding. The symbol of each zone depends on the floor level and is shown in the figures below.
