The aim of the project is to develop an innovative solar collector as well as an innovative modular façade system (MHFS) for hot water and el.en. from solar and wind energy with integrated storage tanks hot water and el.en. that will contribute to solving social challenges such as: 1. energy surge in intensive sectors such as buildings and industry 2. environmental pollution and global warming 3. load on supply systems and energy diff. Target groups are Indian buildings such as factories and logistics centers due to the high total consumption of en., hospitals, hotels and food industry due to the year-round need for top. en., all buildings during construction / reconstruction due to the requirement to meet zero-energy standards
