Performance Evaluation of Advanced Integrated façades in Laboratory Facilities

A wide experimental campaign on transparent advancedintegrated fa~ades with a mechanically, naturally andhybrid ventilated air gap has been carried out both at theDepartment of Energetics at Politecnico di Torino and atLaboratorio Nacional de Engenharia Civil (LNEC) inLisbon. Measurements were perfonned by means of:- the TWINS (Testing Window INnovative Systems)test facility, at Politecnico di Torino- the reversible flow type DSF test cell, at LNEC.At Politecnico di Torino a mechanically ventilatedcliniate faqade and a hybrid ventilated DSF with anoutdoor air curtain ventilation scheme have beeninvestigated. At LNEC a naturally ventilated DSF withdifferent ventilation schemes (outdoor air curtain, indoorair curtain, exhaust air, supply air or, as a limit, a bufferconfiguration) has been tested. The energy efficiency andthermal comfort implications of these different types ofadvanced integrated fa~ade have been evaluated. Theimprovement of performance by varying configwrationsand operative conditions has also been investigated.
