Abstract [en]

Building managers and operators as at Campus Pinkafeld are interested in a cost optimal fulfilment of their energy needs. From a strategic point of view they are interested in optimal investments and upgrades. From an operative point of view they are interested in an optimal use of all available resources. This paper shows how the decision support system (DSS) of the project Energy Efficiency and Risk Management in Public Buildings (EnRiMa) will help with this challenges and the integration of the DSS with the existing energy management system (EMS) is one of the key issues for a successful project. The strategic DSS will inform the building owner about possible new technologies that might reduce the total building energy costs or environmental impact. The benefit of an operational DSS is to enable the building operator to use already adopted energy efficiency improving technologies as pre-cooling, pre-heating or any other demand response related tasks to decrease costs and emissions caused by the heating and cooling system of the building. Assuming an upper and lower limit for the room temperature, we model the effect of active equipment control (via changes to either the set point or the valve flow) on the zone temperature taking into account the external temperature, solar gains, the building shell, and internal loads. The energy required to change the zone temperature in each time period is then used to calculate the energy cost or efficiency in the objective function of an optimization problem. This paper reports on example results for Campus Pinkafeld, shows the technical approach, and that such a flexible approach can save 10% costs only on an operational level.
