Development, Evaluation and Optimization of Blind Controls for Retrofitting of Buildings

February 5, 2010 - 12:00pm

In western Europe, about 55% of the building stock was constructed between 1950 and 1990. During that time, the regulations concerning the insulation of buildings have been much weaker than they became in the last 20 years. Consequently, in these buildings, there is a great potential for energy savings. To exploit that potential, a project was started to develop prefabricated facades which can be mounted on the original facade and include insulation, new windows, new blinds and also new blind controls. A key point of the project was the realistic modeling of the impact on the building energy consumption of the existing controls and the maximum savings potential. By including different stochastic models for occupancy and appliances, we built a complete simulation environment based on the advanced building simulation program IDA ICE 4.0. With this tool, we developed a Model Predictive Control that is adapting to its environment, saves energy and increases the thermal comfort of the inhabitants. The speaker will also give a short introduction to other research topics of the Solar Energy and Building Physics Laboratory (LESO) at the EPF Lausanne.
