摘要: Abstract An experimental study was carried out on buildings constructed in the 1980s adopting vertical envelopes with a glass wool insulation layer cavity. The aims of this are to evaluate conservation state after 25 years, assess actual indoor thermal comfort and compare different retrofit interventions. research included following phases: laboratory tests samples quantify any changes morphological, chemical, physical proprieties material; detailed on-site monitoring order analyze conditions; dynamic simulations impact scenarios satisfy limits imposed by current energy saving standard. results show that fibers binder were affected degradation process thus increasing both water absorption conductivity; consumptions not influenced aging; most effective is introduction an external layer.
