This paper introduces a set of new criteria for assessing the energy-efficiency potential of multilayered building envelopes, focusing on physically measurable aspects of dynamic thermal performance and LCA parameters. Based on EN ISO 13786:2023, the study considers thermal transmittance (U-value), internal areal heat capacity (k1), and decrement factor (f) as thermal performance parameters. Five wall assemblies common in the Ukrainian market - hempcrete, AAC + Rockwool, Porotherm brickwork + Rockwool, wood-chip cement-bonded blocks (Woodcrete) and ICF systems were evaluated through numerical modelling and comparative analysis. To eliminate subjectivity in criteria weighting, physically meaningful criteria, such as internal areal heat capacity (k1) and decrement factor (f) as thermal performance parameters, were proposed for comparison. Results indicate that only wall E (ICF) falls within the recommended thermal inertia range. The study highlights the complexity of MCDA in envelope design and provides physically grounded criteria that can support more objective predesign decision-making.
