Management and control of the power consumption in commercial buildings represents both cost saving and earning potentials. A prerequisite for harvesting the benefits from implementing Smart Grid solutions is access to flexible electricity consumption. Such flexible consumption could potentially be found in commercial buildings that today are operated by a Building Manage System (BMS). The aim of the BMS is to achieve indoor comfort with a minimal level of consumption, but it does not currently take into account the possibility of making the consumption flexible.
The project’s objective is to demonstrate how an add-on to the BMS will enable operators of commercial buildings to provide flexibility services to existing flexibility markets and to DSOs (Distribution System Operators) as a set of DSO specific demand-response services defined in the iPower project and hence support the implementation of Smart Grid solutions.
The demand-response services are implemented using direct control methodologies applying the OpenADR standard from Lawrence Berkeley National Laboratories (LBNL) and demonstrated using the main office building, a newly established office building of 4000 m2, at the Green Tech Center in Vejle and the 15 years old Mærsk Mc-Kinney Møller Building of 3000 m2, at the Southern Danish University.
The demonstration includes both technical investigations of the building’s demand-response capacity with respect to ventilation and cooling, and participatory user studies of how tenants experience the impact of demand-response events on building comfort. The aim of the user studies is to gain new insights, to increase the usability and acceptance of the demonstrated demand-response services.
The results from the technical investigations and participatory user studies are used together with grid data from the Danish DSO TREFOR to evaluate the value that the demonstrated demand-response services can provide to the DSO.
