Optimization of refurbishment choices of a building by the use of the experimental design concepts

In order to reduce the energy consumptions, it is urgent to be focused on existing buildings.The answer is how to determine priorities of interventions on a building to be renovated. The traditional method consists in carrying out a great number of tests and quantifying profits obtained with each solution or combinations of solutions. Our object is to optimize the number of tests to be realized by use of the method of the experimental design concepts which is applied to draw up decisional flow charts of interventions on a building built before 1975.Software Nemrod [1] is used for the experimental design concepts. This stage carried out, the plans are applied by the means of the software Trnsys [2] giving as output the requirements.
