The design proposal for an experimental prototype of a smart and adaptive facade module is presented, including advanced materials, like phase change materials and high insulation materials, based on a dry wooden modular constructive system, with high feasibility and high thermal performances, addressing energy and environmental topics and building technology issues. Objective of this work is the energy evaluation of an experimental facade module called The Mediterranean smart adaptive wall (MSAW) which is designed and optimized for the Mediterranean climate to suite different climate conditions, typical of dry, warm to hot climate contexts, permitting to modify the internal sequence of layers in relation to the different thermal performances requirements, coupling high thermal capacity with reduced thickness. The experimental facade module is a smart constructive solution, easily manageable, with fast and smart assembly process on site and with customizable external finishes. The facade module is composed by a modular frame, realized by plywood timber sheets with modular components too which provide the wall shape without other vertical structural elements. The modular frame is subdivided into two main layer, realized by vertical and horizontal timber elements and interior and external plywood sheets. Into the frame there are wood wool insulation, a vapour barrier sheet in polyethylene, PCM and VIP insulation. An air gap is designed to adapt the energy performances, providing a ventilated facade or increasing the insulation material thickness, as appropriate. Energy simulations and analysis, made to evaluate hygrothermal performances in relation to some reference climate conditions, provide dynamic and stationary thermal behaviours as results, highlighting very high thermal performances.
