Summary
The improvement of environmental performance in building construction could be achieved by prefabrication. This study quantifies and compares the environmental impacts of a Concrete Glulam Framed Panel (CGFP): the basic configuration of this precast component consists in a Cross-Laminated Timber (CLT) frame structure supporting a thin reinforced concrete slab with an interior insulation panel and covered by finishing layers. The research investigates also alternative design of configuration with the substitution of different insulation materials in order to minimize the Embodied Energy and Carbon Footprint values. The boundary of the quantitative analysis is “cradle to gate” including the structural support system; an IMPACT 2002+ characterization methodology is employed to translate inventory flows into impacts indicators. Results present very low values for carbon footprint (60.63 kg CO2eq m-2) and the embodied energy values (919.44 MJ m-2) indicate this hybrid precast structure as a valid alternative building constructions and processes. A detailed discussion of the outputs is presented, including the comparison of the environmental performances depending on different insulation materials.

Summary
This study analyses a new hybrid construction system, the CGFP - Concrete Glulam Framed Panel - that merges the two mostly used materials in frame technology. It is a prefabricated composite wall made of a reinforced concrete slab and a glulam frame. The strength and stiffness of CGFP have been investigated by load-displacements tests and thermal performance was evaluated by means of a hot-box apparatus. Moreover, the environmental impacts of the system are verified defining its Carbon Footprint and Embodied Energy. The efficacy of the proposed system was validated by experimental and numerical analysis. Mechanical and thermal properties have been evaluated by means of experimental and numerical tests whose results have been compared showing a good agreement. By structural point of view, the strength and the deformation capacity are ensured through the consecutive and interactive structural response between the wood frame and the concrete slab. By the thermal and environmental point of view, thermal resistance obtained with different kind of insulation materials have been analysed and a calculation of the amount of the Carbon Footprint and Embodied Energy was already performed. The CGFP panel shows a good thermal performance, a low environmental impact respect to similar construction systems and promising structural behavior.

Summary
This paper presents the analysis of the structural and thermal behaviour of an timber-concrete prefabricated composite wall system, the Concrete Glulam Framed Panel (CGFP) which is a panel made of a concrete slab and a structural glulam frame. The research analyses the structural performance with quasi-static in-plane tests, focused on the in-plane strength and stiffness of individual panels, and the thermal behaviour of the system with steady state tests using an hot box apparatus. The results validate the efficacy of proposed system ensuring the resistance and the dissipative structural behaviour through the hierarchy response characterized by the wood frame, the braced reinforced concrete panel of the singular module and by the rocking effects of global system.
