A comparative study of energy certification systems for buildings

Abstract

Due to the large amount of energy consumption in buildings and the biggest potential of energy and ecology savings, energy efficiency and sustainable construction represent the priorities of modern architecture and energetics today.This paper shows a comparative analysis of energy certification of residential object in realistic environments with the aim of enhancing their energy efficiencies. Subjects of the analysis were two buildings - one in Norway (Oslo), and the other in Serbia (Belgrade). The buildings differ in: climate conditions, size, type of construction, heating systems, etc.The calculation of yearly required heating and cooling energies was performed in German CASAnova software. The methodology is shown hereinafter.Both buildings in this work, according to the calculated yearly heating energy consumption are classified as energy grade C.In both objects it is possible to elevate the energy grade by remediation.This assignment is realized as a part of the collaborative project Sustainable Energy and Environment in Western Balkans that aims to develop and establish five new internationally recognized MSc study programs for the field of Sustainable Energy and Environment , one at each of the five collaborating universities in three different WB countries. The project is funded through the Norwegian Programme in Higher Education, Research and Development in the Western Balkans, Programme 3: Energy Sector (HERD Energy) for the period 2011-2014.
