Focus on structuring and evaluation of existing building stock, its characteristics and improvement potential represents the first step towards its refurbishment. After development of National residential building typology, further steps include its application for planning activities both on national and local level. As a result of adoption of recent regulatory acts in the field of energy efficiency improvement, local governments have an obligation in formulating Local Energy Action Plans (LEAPs) with estimations of savings potentials and related costs. These action plans need to address building stock energy efficiency, where residential buildings have a significant impact on the overall energy performance. In order to properly assess energy savings and investment costs the actual residential building stock characteristics and energy performance levels need to be investigated. Although National typology of residential buildings represents the basis for estimation of local b...uilding stock and formulation of local building typology, different approaches for its application on local level are possible. Two different approaches have been tested through a case study in municipality of Vršac: a topdown and a bottom-up method. Main characteristic of the top-down approach is that it mostly relies of data gathered for the purpose of National typology, while in the bottom-up method a local survey is conducted providing some new data which are then used in adjusting National typology to local conditions. While both methods result in a relevant local typology, their applicability and accuracy of final results depend on municipality characteristics. Results of energy performance calculations are derived and compared for both methods and application guidelines for both methods are defined, which will enable local authorities to properly address this issue in the process of preparation of local energy action plans and support decision making related to investment cost and generated savings.
