Free-running temperature of room equipped with pipe-embedded double skin façade: A case study in Guangzhou

Within an ongoing project, we explore the potential of double skin facades to provide both noise control and natural ventilation capability. Three strategies are investigated: i) Manipulation of sound paths via offset of the openings in the two shells of the façade; ii) Application of absorbing materials in the interstitial space of the façade; iii) Active noise cancelling methods utilizing wave-destructive interference. This contribution describes the overall project but focuses primarily on the active noise cancellation approach. Aside from a comprehensive background research on existing technology, we undertook the design of an actual setting for noise cancellation testing with suitable low-cost components as a proof-of-concept. Results of the experiments are expected to inform subsequent efforts to include noise-cancelling technology in double skin facades.

Testing Room

It is crucial for ventilated double-skin facade (DSF) compared to single- skin facade to avoid high energy consumption, optic pollution and inadequate ventilation problems. In this paper, the performance of ventilated DSF applied to a building located in a university in cold zone (Tianjin) of China is tested. The original conditions of both outdoor and indoor within each testing room are comparatively same.The temperature behaviors of both the ventilated air cavity of DSF and indoor space with different experimental modes during summer are investigated. Additionally, the effects on indoor temperature due to the ventilated DSF with different modes in summer are also analyzed. The results shows that the ventilated DSF is a effective approach to reduce indoor temperature; the opening airflow windows of external façade of the DSF should be effective to lower temperature of both the ventilated air cavity of DSF and indoor space.
