dc.description.abstractBuilding-integrated photovoltaic (BIPV) is a vital element of zero energy or zero emission buildings (ZEB). BIPV systems are integrated into the building envelope and generate electricity on-site during the expected service lifetime of a system of around 25-30 years. The primary function of a BIPV system is seen as electricity production. Hence, factors that affect it are usually in focus when systems are evaluated and monitored after installation. While its function as a building envelope component is usually not appropriately evaluated, neither before nor after installation. One of the main functions of building envelope components is weather protection of inner building structures. A significant impact of precipitation on the building envelope is represented by WDR (wind-driven rain), a simultaneous occurrence of wind and rain. Most wind-driven rain testing is done for façade systems, wall-windows, and wall-doors, while much less is published on WDR testing for roof systems. Furthermore, BIPV systems are barely studied as climate screens. Watertightness of BIPV systems can be evaluated using WDR exposure testing. Water leakages that occur during testing should be quantified to provide valuable information in addition to the usual qualitative data. This thesis contributes to the research on WDR testing by investigating selected BIPV systems for roof integration with means of quantitative measurements. This thesis presents results from experimental testing of a water collection system for quantification of WDR intrusion and provides extensive information on the design and application of BIPV systems designed for roof integration. As a result, a framework is presented, which includes a step-by-step test methodology and a detailed description of the construction of the water collection system. This methodology was applied to three BIPV systems designed for roof integration: solar shingles system integrated along metal roof plates, solar roof tiles integrated along dummy roof tiles produced by the same manufacturer, and large glass-glass solar modules integrated along steel roof plates. The watertightness level was determined for all the tested systems. The systems can be ranked according to their watertightness level, i.e., the maximum level of air pressure applied simultaneously with water spray and runoff water when no water leakages occur on the tested system’s inner side.en_US
