摘要

由于许多财政、经济和社会方面的限制,以及与新建建筑不同的技术和性能要求,将预制技术引入建筑幕墙改造市场仍然困难重重。安装预制外墙模块的技术可行性、施工细节以及实际的舒适度和节能效益仍在研究之中,这也是本文介绍的具体案例研究的目标之一。Renew-Wall 项目旨在创建一种新型模块化、以木材为基础、非侵入式的建筑改造系统,与现有解决方案相比,该项目开发了一系列重要的、完全可定制的创新技术。本文介绍了所设计的预制外墙系统的主要特性,重点是其能耗和温湿度性能。在为期两年的监测活动中,仅对两个相同的模拟建筑(测试单元)中的一个进行了改造。结果显示,模拟年平均节能率为 67%,与现场测量结果完全一致。预制外墙系统还能有效释放蒸汽,降低霉菌侵袭的风险。

Energy retrofit with prefabricated timber-based façade modules: pre- and post-comparison between two identical buildings
The introduction of prefabrication into the building façade retrofit market is still difficult due to many financial, economic, and social constraints, as well as technical and performance requirements that differ from those of new construction. The technical feasibility, construction details, and actual comfort and energy-saving benefits provided by the installation of prefabricated façade modules are still being investigated, as is one goal of the specific case study presented here. The Renew-Wall project aims to create a new modular, timber-based, non-intrusive system for retrofitting buildings, developing a series of significant and fully customisable innovations compared to currently available solutions. This paper describes the main properties of the designed prefabricated façade system, with a focus on its energy and thermo-hygrometric performances. Simulation and laboratory tests are compared with an experimental analysis conducted on two identical mock-up buildings (test cells) during a two-year monitoring campaign in which only one of the two test cells was retrofitted. The results show simulated average annual energy savings of 67%, perfectly in line with what was measured on-site. The prefabricated façade system also demonstrates efficient vapour release and a reduced risk of mould and fungus attack.

期刊介绍: The Journal of Facade Design and Engineering presents new research results and new proven practice in the field of facade design and engineering. The goal is to improve building technologies, as well as process management and architectural design. This journal is a valuable resource for professionals and academics involved in the design and engineering of building envelopes, including the following disciplines: Architecture Façade Engineering Climate Design Building Services Integration Building Physics Façade Design and Construction Management Novel Material Applications. The journal will be directed at the scientific community, but it will also feature papers that focus on the dissemination of science into practice and industrial innovations. In this way, readers explore the interaction between scientific developments, technical considerations and management issues.
