Description
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, along with assembly mass (m) and embodied energy (EE) as additional LCA objective
indicators. 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, three new interconnected criteria were proposed: Dynamic Thermal Performance
Efficiency per mass (DTPEm), per embodied energy (DTPEEE), and per both (DTPEm&EE). Results
indicate that AAC + Rockwool (Wall B) consistently ranks as the most efficient assembly according
to the DTPEm&EE criteria. At the same time, Wall E (ICF) aligns with the recommended thermal inertia
ranges but exhibits the highest embodied energy, resulting in the lowest DTPEm&EE. The study highlights the complexity of MCDA in envelope design and provides physically grounded criteria that can
support more objective predesign decision-making.
