Energy consumption for space heating and air conditioning holds a significant share in the total energy consumption, among them residential and tertiary buildings being on the first places. This strong energetic dissipative character of different elements of the building envelope offers multiple possibilities of intervention aiming to reduce the heat losses. The Romanian requirements concerning the elements evaluating conformity with the Standard C107-2010 and the Order no.2641/2017 are given with a focus on thermal bridges influence aside with a short description of different ways to estimate this influence in EU countries. The paper presents in general, concepts to be used in order to achieve the nZEB standard developed by the Energy Performance of Building Directive having in mind a mitigation of greenhouse gases, GHG emission. In this context, is presented the role of balcony elements as undesirable “heat exchanger” and this thermal bridge is depicted together with some ways to avoid this inconvenience.
