Analysis of Power Consumption Data from Smart Metering of Parking Garages with Regard to Influencing Factors

This paper examines load profiles of three commercial parking garages and, in this context, created individual load profiles for them. A considerable proportion of the operating costs of parking garages is accounted for by energy and maintenance costs. The lighting systems and the ventilation system are the main cost drivers. The aim is to use these load profiles to estimate energy consumption and its structure over the course of the day, week and year, as well as to identify efficiency measures and potential savings with regard to operational energy costs. The necessity of such individual load profiles results on the one hand from the lack of current representative commercial profiles for this industry, and on the other hand from the heterogeneity of the individual buildings. Here it becomes clear that the construction and energy concept of the parking garages have a great influence on the consumption patterns. Therefore, parking garages were equipped with a detailed metering infrastructure in the project ”SmartPark” funded by the BMWK.
