Abstract
In Poland, there are more than 5 million single-family detached houses, and 35% among them are non-insulated. In the article, we present a concept of application of the case-based reasoning (CBR) systems to support the process of energy retrofit of single-family detached houses. In the proposed CBR system, the energy retrofit process was described using parameters with text and numeric values and also using linguistic variables defined using fuzzy sets. If an investor, designer or contractor encounters a problem in the process of the energy retrofit, he may look for a solution to this problem or similar problems in the CBR system. If he does not find a solution and creates it himself or modifies an existing one, he should put it in the CBR system so that others can benefit from his experience. The proposed CBR system will help in solving the basic Polish (but also Eastern European) problem of energy-saving constructions which is the lack of adequate knowledge of participants in the investment process.

Buildings are responsible for 40% of the global energy consumption and have a longlasting negative impact on the environment due to the greenhouse gases emission

Summary
Buildings are responsible for 40% of the global energy consumption and have a longlasting negative impact on the environment due to the greenhouse gases emission. In the case of newly designed buildings, there are many technical and technological solutions leading to high energy efficiency standards of the buildings are they are economically justified [5,6,7]. The achievement of passive or zero energy building related to energy retrofit requires a lot of knowledge and experience in the field of possible technical solutions and usually consumes much money, while the choice of renovation and installation technologies is often determined by existing construction solutions in the building [4,5,6,7]. The decision support tools in the process of energy retrofit become of great value. The concept of CBR (case-based reasoning) was created to support the decision makers in the process of energy retrofit
