Determination of the energy performance indicator of kindergartens through design, measured and recommended parameters

Abstract

Research analyzed the influence of parameters derived from urban planning, architecture, building materials and technology, building physics, users and patterns of use, the measured thermal performance of the envelope and thermal comfort parameters on the energy performance indicators of two representative kindergartens. The paper presents an energy performance indicator through design and measured parameters of representative samples of old and new kindergartens located in the temperate climate zone of Banja Luka (northern Bosnia and Herzegovina). When the data presented in EN 13790 concerning the patterns of use and design temperatures for residential buildings or educational and cultural buildings is compared with the measured, surveyed, analyzed and estimated kindergarten data, the design parameters are found to deviate from the measured parameters.

On the basis of the presented analysis, it is recommended that measurement of the thermal performance of envelopes of old buildings become a mandatory part of energy audit, and that an appropriate set of parameter values be used in the calculation of the energy performance indicator of kindergartens. Kindergartens must be introduced as a specific type of buildings in policies related to the minimum requirements for the energy performance of buildings and rational use of energy, energy audit and certification of buildings.
