Abstract
The paper estimates the thermal perfomance of effective building envelopes from organic materials for the construction of
low-rise buildings. The popular types of walls made of natural energy-efficient materials with low carbon footprint are considered
in numerical assessment: hempcrete, adobe, strawbale panel, earthbag and cordwood. The influence of the constructive
layer type of the envelope on the amount of thermal inertia time is analyzed. It is revealed that the hempcrete wall
has the biggest thermal inertia time, the wall of the earthbags has almost ten times smaller. The walls made of adobe and
strawbale panels have practically equal time of thermal inertia. For more objective analysis, by taking into account the variety
of physical and physical-mechanical parameters of the envelopes’ material, the concept of integral criterion of the envelope
energy efficiency potential is proposed. The estimation of the integral criterion of energy efficiency potential is calculated
by the Analytic Hierarchy Process and the proposed method is fulfilled. Comparison of the integral criterion of energy
efficiency potential for different wall types which was made by menas of two abovementioned methods has shown the
same order of magnitude.
