Abstract: An HVAC duct or utilicore for substantially containing air flowing longitudinally therethrough has at least one wall comprised of a poured high thermal mass material with at least one pipe embedded therein during a pouring process, the at least one pipe for circulating a fluid throughout the at least one wall at a temperature that is different from an ambient temperature of the air flowing through the utilicore, for effecting heat transfer through the at least one wall between the fluid in the at least one conduit and the air flowing through the utilicore. A side wall of an elongate monolithic poured concrete building construction module, having a substantially planar main wall and at least one side wall extending substantially parallel to a longitudinal axis, having a pipe embedded therewithin, may form at least a portion of an element that defines the utilicore.

Abstract: A precast monolithic concrete prefabricated, composite building construction module formed of a substantially planar rear wall. The rear wall has embedded therewithin a radiator pipe for circulating a fluid at a temperature that is different from an ambient temperature of the modular component within the rear wall. The module may comprise at least one side wall integral with the rear wall that terminates at one end at a corresponding end of the rear wall. The rear wall has a length and each of the at least one side walls has a length and extending in a first direction substantially normally away from the rear wall sufficient to substantially enclose and define walls of a standard facility, the at least one side wall supporting the rear wall to cause the module to be free-standing while devoid of lateral support.
