Abstract

Des modes de réalisation de la présente invention donnés à titre d'exemple concernent un panneau de construction préfabriqué. Le panneau peut comprendre une structure de cadre, une partie centrale couplée à la structure et une couche cimentaire recouvrant au moins partiellement la partie centrale. Le panneau peut également comprendre au moins une cavité s'étendant partiellement à travers le noyau. La cavité peut être conçue de manière à y faire passer un conduit. Le conduit peut être couplé à un système de distribution de service et le conduit peut coupler un dispositif couplé au panneau au système de distribution de service.
