Monitoring Energy with ThyssenKrupp Real Estate
The energy consumption of artificial lighting systems represents a 20-40 % of the primary energy consumption of an administration building. After the reduction of an approved total primary energy requirement by 30% with the adoption of EnEV 2009 and with the perspective of another reduction by 30% as agreed by the federal government in the resolutions at Merseburg, the use of electronics to realize potential savings must also occur in the area of artificial lighting. If it is possible to successfully switch off the artificial lighting systems during times of extended absences, and to appropriately adjust the artificial light volume to the daylight in times of presence, only then can be ambitious energy goals be achieved.
The idea to equip a limited number of offices with standard floor lamps, equipped with electronics for a presence and daylight dependent control, in a typical office building with a conventional artificial lighting system and to accompany these for one year metrologically in comparison with existing offices, was developed in 2007 during meetings with the Herbert Waldmann GmbH & Co. KG. After an intensive search, a neutral partner was found in the ThyssenKrupp Real Estate GmbH in Essen that developed great self-interest in the topic in view of major upcoming construction measures and agreed to for the study to take place in 12 selected offices. The measuring campaign started in spring 2008 and lasted for more than a year. Approx. 3.5 million data has been recorded during this time frame in a 5 minute cycle and was subjected to a systematic analysis. The project was concluded with a final analysis in the summer of 2009.

For more information read the brief version of the overall 36 page long final report “Monitoring ThyssenKrupp” containing the most important data. This brief report primarily focuses on the measured energy consumption.
Detailed descriptions of the offices, measuring concepts and evaluation of the control response are included in the long version, and can be obtained from Waldmann if needed.
* One year's recording of the energy consumption in 12 offices of energy-saving potential of artificial lighting systems that are dependent on presence and daylight detection. Performed in an office building of ThyssenKrupp Real Estate GmbH in Essen, on behalf of Herbert Waldmann GmbH & Co. KG.
