Resource Efficiency in Architecture and Planning (REAP)

Building physics, Energy-optimised building and passive air conditioning, Resource Efficiency in Architecture and Planning (REAP)

Office hours during the semester: by appointment 

Udo Dietrich studied physics at the Friedrich Schiller University in Jena and graduated with a focus on theoretical optics. Thereafter he worked on architectural building physics, in various engineering offices and universities. In 1995, he took up a professorship at the University of Applied Sciences (HAW) in Hamburg – since 2006 HafenCity University (HCU) Hamburg - in the areas of Building Physics, Energy-Optimised Building and Passive Air Conditioning. He has developed computer software for building energy simulation and has a particular interest in the comfort of building occupants.

Focus of research:

Integral planning: energy – environment – comfort – quality of architecture
Support for sustainable building
Building simulations
