Innovative Approaches for Assessing Energy Performance in Existing Buildings
Existing buildings often exhibit a notable performance gap between predicted and actual energy efficiency due to limited knowledge about their thermal envelope, physical characteristics, and hidden defects. Understanding these parameters is crucial for developing cost-efficient retrofit strategies that reduce operational costs and carbon emissions. This study emphasizes the importance of on-site measurements and advanced diagnostic methods to enhance energy performance evaluations and support sustainable building practices. Challenges in Assessing Existing Building Performance Accurately evaluating the energy performance of existing buildings is hindered by incomplete or unreliable structural data. Hidden defects, variations in material properties, and deterioration over time contribute to discrepancies between modeled predictions and actual energy usage. These uncertainties make it difficult to design effective retrofits, highlighting the need for more precise assessment tech...
