A dataset has been uploaded for the Master of Engineering in Civil Engineering program. The dataset is titled 'Design of a prototype building panel for rainwater storage and energy generation'. The data was collected through a practical study conducted in controlled settings where rainwater depths and generated energy from photovoltaic (PV) cells were measured and uploaded onto an Excel sheet. The data was acquired to determine the quantity of water harvested in a prototyped storage tank, the output power generated, and the technology-related costs.
