Ziezo tool is an application that captures the daylight and energy performance of Ziezo Window systems. The tool has been developed as part of the Engineering Doctorate thesis: "Window-integrated Bifacial PV Coupled with Solar Shading: A Multi-Parameter Model and Tool to Evaluate Daylight and Energy Performance". The thesis and work have been carried out by Mina Ishac, within the Chair of Building Performance Group in the Building Physics and Services Unit at Eindhoven University of Technology. This tool captures the daylight and energy performance of Ziezo Window systems, adapted to dynamic climatic conditions, window sizes and orientations. It aims to be informative, user-friendly and interactive. The tool, furthermore, captures the momentarily and annual daylight in light of solar radiation profiles of Eindhoven in the Netherlands to better understand the dynamic climatic conditions that affect lighting levels. The tool presents monthly and annual energy consumptions, and provides insights into the optical and thermal properties of Ziezo window. The tool retrieves simulation data, performs basic analysis on the data, and then presents this data to the user. The tool was designed in Visual Basic for Applications (VBA) for Pilkington Nederland B.V. as the target end-user of the tool. An overview of all Ziezo cases in the tool, explanation of detailed functions, inputs, key performance indicators of the outputs, boundary conditions of the model, use cases can be found in the resources below for: 1) Engineering Doctorate thesis, and 2) demonstration video of the tool.
