AB An ecological mortar is designed from industrial sub-products, with the objective ofutilizing both the slag residues, generated during steel manufacturing processes, and the waste fromPolyurethane Foam (PF) panels, generated during refrigerator chamber manufacturing processes.The ecological mortar design involves the dosing of Electric Arc Furnace (EAF) slag, together withfinely ground Polyurethane Foam, cement, and additives. An energy efficient prefabricated block isdesigned with the mortar, for use in construction, and its energy performance is assessed as amaterial inserted within the envelope of a service sector (hospital) building, either as an exteriorskin, or as an enclosing component within the façade interior. The main contribution of this researchis the characterization of the thermo-physical and mechanical properties of a new prefabricatedpanel made with recycled materials. The full characterization of the properties of these newmaterials is presented and discussed. The new prefabricated panel demonstrates adequate thermomechanical characteristics as a substitute for traditional materials, while improving thesustainability of the building. As a secondary objective, the energy behaviour of the new panelswhen integrated in a real building is presented by means of a case study simulation. The use ofcomputational thermal simulation confirmed that the properties of the prefabricated blockinfluenced the annual thermal demand of the building for heating and cooling. Improvements tothe thermal inertia of the building envelope were also confirmed with the inclusion of PF waste,giving the mortar an energy performance that was similar to conventional materials, in such a waythat its use in façade construction may be validated, in addition to its environmental benefits, dueto it having been manufactured with critical recycled industrial waste such as EAF slag and PF,thereby contributing to both the circular economy and sustainable development.
