Layer thickness optimisation of multilayered envelope

Abstract

The thermal performance criteria CTP has been proposed as the assessment parameter, which could be considered when the decision-making demand for the energy-efficient multilayered wall assembly comes into the picture. As the parameters of the proposed criteria CTP, the wall width, wall mass and wall’s internal areal heat capacity were used. The current paper mainly emphasises the proposal of criteria which depend on physical characteristics only. The “best” wall assessed by CTP criteria was made of 375 mm AAC D300 Rockwool insulated wall, and the “worst” wall assembly was Wall type C for 1300 kg/m3 brickwall masonry + Rockwool as insulation material. Additional influence factors and verification and results validation should be provided when comparing criteria and assessment methods.
