IWG5 online tool to evaluate and compare energy efficient renovation options for buildings

EURAC Research Center has developed a new online tool designed to support energy efficiency initiatives and renovation strategies for European residential and office buildings.

This tool, created as part of the Implementation Working Group on Energy Efficiency in Buildings (IWG5), aims at enhancing energy efficiency and reducing CO₂ emissions. It provides a comprehensive parametric simulation-driven database that addresses energy consumption, costs, and environmental impacts across various building typologies.

The IWG5 tool offers a range of baselines for five European climate zones, enabling users to define benchmarks based on existing building characteristics such as building envelope thermal transmittance (U-values), Heating – Ventilation and Air Conditioning (HVAC) system types, and efficiency levels. By integrating data from extensive simulations and life cycle assessments, the tool equips users to evaluate renovation options effectively, leading to more informed and sustainable decision-making by public authorities, building owners or operators and other stakeholders planning large-scale renovation projects.
