During the first funding period (05/2014-04/2016) several textile prototypes with thermo-active abilities were produced with appropriate readymade methods. Following, the prototypes were analyzed for their mechanical and thermal properties. Heating and cooling performance data of the textiles have been derived from experiments carried out under reproducible conditions in a test chamber designed for these kind of testing.Additionally, comprehensive numerical studies of the thermal behavior of the prototypes were performed. First, comparative simulations of the experiments were done. Secondly, the results were transferred to applications in real rooms. The available data show a very good match between experimental and numerical results as well as a great potential of thermo-active textiles for space heating and cooling.The development of prototypes is going on, based on both, experiments and simulations. It will be transferred into two demonstrators which are in dimensions and concerning textile technology able to heat and cool a climate chamber. Thermo-active textiles will be equipped with sensors to improve control operations. The functionality of the demonstrators will be validated by experiments in the climate chamber and by simulations in the virtual climate chamber.Furthermore, based on previous numerical calculations comprehensive simulations are planned regarding thermo-active textiles in real applications.

在第一个资助期内（2014年5月至2016年4月），采用适当的现成方法生产了几种具有热活性的纺织品原型。随后，分析原型的机械和热性能。纺织品的加热和冷却性能数据来自于在为这些测试设计的测试室中在可再现条件下进行的实验。此外，对原型的热行为进行了全面的数值研究。首先，对实验进行了比较模拟。其次，将结果应用于真实的房间。现有的数据表明，实验和数值计算结果之间有很好的匹配，以及热活性纺织品在空间加热和冷却方面的巨大潜力。原型的开发正在进行中，基于实验和模拟。它将被转移到两个示范，这是在尺寸和有关纺织技术能够加热和冷却气候室。热活性纺织品将配备传感器，以改善控制操作。演示器的功能将通过气候室中的实验和虚拟气候室中的模拟进行验证。此外，基于先前的数值计算，计划对热活性纺织品在真实的应用中进行全面的模拟。
