Since 1999 he has been the Head of the Research and Testing Centre for Solar Thermal Systems (TZS). His main research interests lie in the field of solar thermal technology, focusing on advanced heating and cooling systems, thermal energy storage and the development of performance testing methods as well as energy efficient solar buildings. Harald Drück has authored or co-authored around 300 publications in the field of solar thermal energy and heat storage. He is convenor of several German and European working groups related to the standardisation and testing of solar thermal systems and components, such as the Solar Keymark Network, the Global Solar Certification Network and the Solar Certification Fund. He acts as an advisor to several high-level international organisations, is chairman or member of the scientific board of several conferences and workshops and teaches a highly successful postgraduate course on solar thermal energy at the University of Stuttgart. Furthermore he was one of the initiators of the German and European Solar Thermal Technology Platforms and is currently a member of the steering committees of both platforms. In addition to his activities at the University, he is the Director of SWT – Solar- und Wärmetechnik Stuttgart. SWT is a spin-off company of ITW and is a service provider in the field of solar thermal energy.
