“…The contribution is aimed at a detailed survey of the impacts of energy saving measures on individual types of households, which also documents an interesting conclusion in the form of a discrepancy between the declared efficiency of measures and the actual (disproportionately low) savings of households. The evaluation of the effectiveness of programs to support the reduction of the energy performance of residential buildings in Ireland is the subject of the contribution [9]. Within the presented research, an ex-post analysis of the efficiency of energy-saving measures implemented in the period 2006-2012 is carried out.…”

This contribution is focused on the issue of the application of energy-saving measures in the construction of new residential properties and their optimal combinations with regard to the life-cycle costs of these buildings. The aim of the research is to create a methodological basis for considering the economic and financial impacts of various combinations of energy-saving measures, aiming at the optimization of these measures and the sustainability of developer projects. The research methodology is based on the principle of building life-cycle costs, which serve as a key criterion for the process of choosing the optimal combination of energy-saving measures and for comparing a conventional solution with an innovative solution including the application of energy-saving measures. The result of the research is the methodological approach for the design of technologically proven combinations of energy-saving measures, which will lead to optimization of the life-cycle costs with regard to the reference variant represented by a conventional solution. This approach is subsequently verified on three case studies of residential properties with a proposal for the optimal combination of energy-saving measures in the form of photovoltaic panels and a water-air heat pump. The added value of the paper consists of the possibility of optimizing the building construction project from the point of view of energy-saving measures already in the design phase.

“…Several studies have investigated possible decarbonization pathways for the European residential sector [7][8][9][10][11][12][13][14][15]. For instance, the analysis by [12] focuses on energy efficiency investment decisions in the EU residential sector, considering the market and non-market barriers, policy instruments, and consumer behaviors.…”

“…For instance, the analysis by [12] focuses on energy efficiency investment decisions in the EU residential sector, considering the market and non-market barriers, policy instruments, and consumer behaviors. The analysis by [13] shows the impact of the EU decarbonization policy in Central, Southern, and Eastern Europe, while [14,15] focus on the EU decarbonization policy implications at the country level. The above-mentioned studies reveal a gap in the current literature-a misalignment between the scope of EU policies and the regions under investigation.…”

Transformative actions are crucial across all sectors emitting greenhouse gases. Nonetheless, energy transition research to date displays a notable imbalance, with a larger emphasis on the supply side than on the demand side. The present study addresses this inequity by focusing on residential sector space heating demand, a frequently overlooked energy service that currently contributes substantially to global greenhouse gas emissions. Our primary objective is to pinpoint effective climate policies and space heating strategies that align with the EU’s ambitious targets for emission reduction. We employ the recently developed TIMES-Europe model to conduct a comprehensive analysis of the residential sector’s policy frameworks, technological advancements, and associated costs. This analysis aims to determine the measures necessary to meet ambitious climate objectives within the European context. To achieve this, we formulate four distinct scenarios, each representing varying levels of ambition and collaboration among EU member states, thereby providing insight into the pathways toward achieving these targets. By implementing current intended EU policies on the renovation of dwellings, we project a substantial reduction of at most 850 PJ, or, i.e., a 19% decrease, in yearly energy demand for space heating between 2020 and 2050. In contrast, if the recent pace of dwelling renovation within the EU were to continue, space heating energy savings from renovation would only amount to less than 400 PJ/yr (i.e., a 9% reduction) in the same period. In our more ambitious climate scenarios, phasing out fossil fuels leads to widespread electrification of the European residential sector, and by 2050, electricity from heat pumps and electric boilers accounts for over 68% of the total residential sector space heating demand. The outcomes of our study underline the importance of implementing the currently planned EU policies. We also demonstrate the necessity for collaboration among EU member states in order to attain the common European climate targets under the most effective resource allocation.
