A study on database of modular facade retrofitting building envelope

摘要

The purpose of this paper is to investigate the prefabricated retrofit facade construction features of thermal insulation. Research done so far mainly concentrates on specific structures of modular renovation construction for building envelope regardless of common features and thermal insulation characteristics. This study utilizes matrix method to establish an entire structure system basing on a proposed original insulation structure and compare various heat preventing capacity. Different layers in construction are investigated to assess the influence on insulated performance of them. The result shows that the VIP panel, ventilation duct and levelling layer are the most significance factors affecting whole system insulation performance. Diminishing ventilation duct size and adding VIP panels could improve building envelope insulation ability efficiently in the process of building renovation. (C) 2020 Elsevier B.V.
