Double skin façades are adaptive envelopes that aim to improve building energy consumption and comfort performance. Their principle relies on the dynamic management of cavity's ventilation flow shading devices, which can integrate with environmental systems. This research demonstrates possibility modifying existing buildings study unconventional envelope solutions. Scenarios A B show insignific...

To obtain optimal efficacy toward energy saving in buildings, numerous approaches have been persistently developed and innovated. Double Skin Façade (DSF), one of the keys to efficiency thermal enhancement, is increasingly drawing attention from designers researchers speculating its benefits. Nowadays, there are still some doubts about performance DSF as it provides pros cons. Therefore, this r...

This paper describes CFD modelling of Double Skin Façades (DSF) with venetian blinds inside the façade cavity. The 2-D modelling work investigates the coupled convective, conductive and radiative heat transfer through the DSF system. The angles of the venetian blind can be adjusted and a series of angles (0, 30, 45, 60 and 80 degrees) has been modelled. The modelling results are compared with t...

Currently, the energy and environmental efficiency of buildings has led to development cladding systems that may help reduce structure’s demand, using techniques such as Permeable Double Skin Façade (PDSF). Given complex aerodynamic interactions, presence an external porous screen in addition inner skin play a crucial role fluid-dynamic characterization buildings, making definition wind effects...

This paper describes the preliminary findings of a post-occupancy evaluation campaign conducted on contemporary and energy-efficient office buildings with different façades treatments. The aim is to investigate occupants’ comfort and perceived productivity and to observe to what extent the space appearance and the façade design play a role in the ultimate user’s satisfaction and overall comfort...

Double skin façade (DSF) system is used in high-rise buildings increasingly in the hot summer and cold winter zone in China, due to its advantages in sound proof, aesthetic appearance and energy efficiency. This paper demonstrated a method of obtaining the thermal characteristics of the double skin façade system using computational fluid dynamics (CFD) techniques, and evaluated the energy perfo...
