By reviewing numerous national typologies, methods and strategies for the energy optimization of the building stock, the following was noticed:
• by following the guidelines given within the project TABULA, it is possible to structure a national typology as a quality base for identifying and implementing the measures of energy optimization of building stock;
• for structuring a quality typology, it is necessary to have a quantification that implies reliable, detailed and updated data sources;
• a unique national typology, however complex it is, is not enough for a wider implementation of measures into practice – additional (attendant) typologies are needed, together with instructions, tools etc.
• For solving many questions in the domain of methodology, the rich and numerous experiences of the developed countries can be efficiently used (they are available in various publications).
Taking into account the previous researches in this field, an efficient structuring of the concept of the Serbian national typology can be expected according to the guidelines from TABULA, while for the development and quantification of types, it is necessary to obtain data that are not available in the official statistics, nor in the published surveys.
