- Abstract
In Romania, the energy performance design of buildings and related facilities is made on the hypothesis of standardized conventional climate data determined based on statistical average values. The Romanian territory is divided in five different climate zones that have different exterior climate parameters. This paper evaluates to what extent the energy demand vary in case of a residential building already built in the climatic zone II if it transposed to each of the other four climatic zones of Romania. Thus, the study starts from a baseline case of an energy-efficient building, designed and built in compliance with the principles of the passive house standard, in Timis County. Also, another purpose of this study is to establish U-values for the envelope elements, necessary to achieve the passive house standard for each of the five climate zones, in the conditions of the architecture and building services chosen for the already built house in the climate zone II. The energy performance calculations indicate different energy requirements for each of the five climatic zones, except the results for the climatic zone III and IV which are very similar. This paper emphasizes de particularity of the energy efficient design related to the climatic zone and the need of a careful planning in order to obtain the desired energy efficiency at a cost optimal level.
