  abstract = {{B}ringing nature into urban areas is largely recognized as one of the multiple benefits of green walls. {A}mong the existing types of living walls, those made from durable building materials have a longer lifespan and require less maintenance than many typical green wall systems. {I}n that context, there is a need to study the bioreceptivity of materials, i.e., their ability to host living organisms. {T}his paper presents a novel method to study the bio-receptivity of materials, by enhancing the biological and physicochemical exchanges in different mixtures of crushed materials and substrates, and by measuring their effect on plant growth. {F}or this experiment, we crushed and sieved four different building materials (3 types of concretes and 1 brick) to increase their contact surface. {W}e then mixed them with substrate with or without compost additions. {T}he mixtures were used as growing media for the cultivation of two wild mural plant species in a glasshouse. {P}lant growth and the physicochemical evolution of the mixtures were monitored for one year. {T}he study shows the physical and chemical differences between the building materials, their interactions with substrate composition, and their effect on plant growth. {T}wo main results appeared: (i) high p{H} (>8) was the major constraint against plant growth (ii) compost addi-tions significantly compensated for adverse characteristics of the materials. {A}ssuming that higher plant growth is associated with better bioreceptivity, this experiment introduces a quantitative method that could contribute to the evaluation of the agronomic properties of building materials. {T}he results allow us to make recommendations for {L}iving wall and {T}echnosol design.},
