- MSc thesis Niko Heeren This work investigates the ecological potentials of load management in buildings. Per square meter approximately three times the thermal energy is irradiated, than it is consumed by an average German building per year. The aim of this work is to investigate possibilities to approach annual energy supply and demand. The first section identifies the environmental potentials of load management. It shows that it fosters utilization of Renewable Energies. Furthermore, the demand in operating reserve for electricity can be reduced. That is important since it can cause considerable environmental impacts. The second section explores the different possibilities of load management in buildings. The current regime of electricity generation in Germany conflicts with the power generation from Renewable Energies. Thus, a possible pathway of electricity network transformation is presented. New technologies suggest that in the future new possibilities of load management will emerge. For instance, seasonal shift of thermal energy can be realised by means of exergy storage and heat generation by means of heat pumps. Another example is solar- thermal power plants that are able to provide daylong electricity from solar energy. The third part of this work presents a model for the evaluation of electricity storage and Demand Side Management (DSM) of appliances. By means of the model it is illustrated, that direct ecological potential of load management is limited. Measures, such as energy efficiency and fuel switch for thermal energy production appear far more effective, in terms of abatement of greenhouse gas emissions. Nonetheless, the concept of load management allows valuable possibilities to transform electricity networks in the future. DSM and energy storage are also a means to provide operating reserve. The magnitude that could be supplied by these measures exceeds the aver- age operating reserve that is currently held by German network operators. Electricity from Renewable Energies conflicts with the baseload in the electricity network. The electricity network of the future should be able to make use of mostly Renewable Energies. Load management will be an important technique to establish such a network.
