The Swedish Parliament has decided that the energy consumption in buildings must be reduced. This also applies to existing buildings to which the historically valuable buildings belong. When improving energy efficiency in historically valuable buildings managers often experience that the process of choosing acts takes too long time because there is no rational way to compare different consequences of the acts. Antiquarians on the other hand, often have a different opinion and experiencing that managers often look more to the potential of savings rather than the impact on the cultural value. The aim of the essay was to make the comparison of energy efficiency acts in the historically valuable buildings more transparent for managers. Through literature study, document analysis, interviews and case study the following questions has been answered: - What cultural-historical factors should be taken into account at improving energy efficiency in the historically valuable buildings? - How can energy-saving acts be evaluated in a model which takes into account the potential of energy saving and the cultural factors identified in question 1? - How should the model from question 2 be used for comparisons of possible actions in an existing building? Cultural-historical factors were identified and formed the basis for the model that was developed. For each factor criteria was connected with different point levels for evaluation. A matrix was developed to visualize the result. To demonstrate the function of the model a case study was carried out where the model was used in an existing building. To enable evaluation of selected acts both observations and calculations were performed. The case study was performed at Länsresidenset in Jönköping. The results of the study shows that Reversibility, Long-sightedness, Impact on visual impressions and experience, Impact on historically valuable parts and details, and Other is important cultural factors to consider when improving energy efficiency in historically valuable buildings. Criteria for evaluation should be formulated carefully and generally to fit each type of action and to avoid subjective assessment. To obtain a perspicuous comparison colors should be used for grading. Furthermore, weighting should be used to adjust the priority level of each individual factor in a specific building. After evaluation of actions in a specific building has been done specialists in various fields should be consulted for final selection of acts.
