Research findings from Sapienza University of Rome emphasize the critical role of energy efficiency in buildings to mitigate climate change, particularly in the context of the European Green Deal's goal of achieving carbon neutrality by 2050. A new study presents a decision-support tool for energy retrofit interventions in existing residential buildings, highlighting the need for streamlined selection processes and cost-saving simulations. The research suggests that unlike other tools, this approach enables the estimation of economic savings and Net Present Value (NPV) of proposed insulation solutions, identifying available incentives for intervention.

Key Takeaways:

  • The building and construction sector significantly impacts CO2 emissions and atmospheric pollutants, contributing to climate change.
  • Improving energy efficiency in buildings is essential to achieving carbon neutrality by 2050, as outlined in the European Green Deal.
  • A decision-support tool for energy retrofit interventions in existing residential buildings has been developed, enabling preliminary energy assessment and identification of specific cases based on construction period, building type, and climate zone.
  • The tool streamlines the selection process of vertical and roof closures based on construction age and building type, estimating potential economic savings and NPV of proposed insulation solutions.
  • The study highlights the importance of energy efficiency in buildings, particularly in the context of the European Green Deal, and provides a framework for practitioners to select pre-calculated, efficient, and sustainable prefabricated solutions.
  • The tool developed in the study offers a matrix designed to guide practitioners in selecting pre-calculated, efficient, and sustainable prefabricated solutions based on energy performance criteria.

Statistics:

  • The building and construction sector contributes significantly to climate change, with CO2 emissions and atmospheric pollutants having a major impact.
