Each country should develop it's own building typology. For this purpose the state must have a system of classification defined by year of construction, building function and size of the existing buildings. It should then find examples that represent that category. The relevant data of these objects (external walls, windows, exterior doors, roof and slab above the ground), along with their respective photographs of buildings create countries typology. Its importance lies in the fact that when the object is being renovated regarding energy savings, rising the comfort or simply to maintain the structure of the building must know in advance some of the features of the building that are typical for its type. A typical classification of building stock will give us preliminary data for quick calculations on the potential energy savings, sustainability of the building structure, historical values etc.. With a good prepared typology , experts will have data regarding building construction, building materials, heating systems etc, and these data will serve them in their work whether it is engineering and scientific research. This paper will present the first steps in Kosovo for creating building typology and its application by analysing existing projects in this field that were conducted from Kosovo Government, World Bank, EU and other NGO or Companies. The paper will also give best solutions for improving thermal characteristics by implementing Energy efficiency measures. It will also show what are these measures and how will they affect heat transmission and energy consumption in general.
