Technical measurements investigations of an office building characterised by low energy use and high thermal comfort

The building of the Centre for Sustainable Buildings in Kassel was established in 2000. The detailed monitoring within the framework of the SOLAROPT research programme covered the years 2002 and 2003. The building is the extension of an old factory; this required certain architectural necessities. From the planning stage to the construction of the building, special consideration was given to aspects of building physics; thus, excellent thermal properties could be achieved, which were recorded by technical measurements. Detailed measuring data on the load performance of the heating systems, temperatures during the heating period and under mid-summer boundary conditions, air quality parameters and air change rates, illumination and temperature on the surfaces of the building elements as well as in building components, especially in the field of thermally activated systems, are presented.
