Abstract
This paper is part of broader research aimed at determining the relationship between energy performance and energy costs as a part of the operational and life cycle costs in school buildings in the Federation of Bosnia and Herzegovina (FBiH), as exceptionally important social and public buildings. The research was conducted by statistical analysis of data collected from documents of detailed energy audits (DEA) for 185 school buildings in FBiH in relation to construction periods. The paper analyzes the characteristics of buildings such as construction period, building envelope characteristics, climatic conditions, efficiency of installed space heating system, number of users and heating mode. The aim of this research was to determine the energy performance for the existing state and to compare them with the allowable values in accordance with the applicable legal regulations. There is a performance gap between predicted (calculated) and measured (actual) delivered energy for space heating. This research shows poor energy performance and provides a basis for developing strategies and plans to improve energy efficiency. The results of the energy performance of school buildings in the FBiH are the first step towards the development of a model for predicting energy costs.

This paper presents the results of research into the characteristics of school buildings in the Federation of Bosnia and Herzegovina (FBiH) and the energy consumption for space heating as factors that have a significant impact on achieving thermal comfort and energy costs
The statistical set or population is represented by school buildings in FBiH, and the collected detailed energy audits (DEA) documents represent the basic statistical sample for collecting data on the characteristics of the statistical set or population
Summary
School buildings are one of the most important facilities in a community given that students spend about 25% of their time inside classrooms. A school usually has a considerably higher occupancy rate than any other type of building [1]. School buildings have a great social responsibility due to their educational purpose. That is why the energy characteristics of these buildings are of great importance, along with the appropriate levels of Indoor Environmental Quality (IEQ) [2]. The test results of children showed improved results in proportion to the increase in complaints IEQ factors [3]
