Lately, a double skin façade (DSF) has been increasingly popular as an aesthetic and shading device. A façade with a secondary skin is employed in buildings to let natural light flow into the building without glare and heat. The purpose of this study is to examine the performance of secondary skin in buildings and to investigate the level of natural lighting in buildings that meets visual comfo...

The analysis of a glass double skin façade equipped with integrated movable shading devices is presented, employing three different modelling levels: optics of materials, fluid dynamics of the double skin façade and building energy balance; the aim is to optimize both winter and summer energy performance. The model is developed for a façade oriented towards the south and taking into account the...

One of the most important methods of saving energy and providing indoor comfort conditions of buildings is the careful design of the façades. A “double skin glass façade” is optimally one of the best options that control the heat interaction between indoor and outdoor spaces. Two kinds of heating energy is usually transmitted through exterior envelope “conduction” and “radiation”. Double skin g...

Energy efficiency in office buildings has been the center of attention for many researches. This special attention is due to highly energy consumption in this building type. Refinement of facade and building’s envelop is a good approach to reduce buildings energy requirements. Double skin facade concepts are commonly used to achieve that object. Although the concept is not new, there is a growi...

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...

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...

In this research, an analytical method for quantification of the thermal energy performance improvement for a building integrated photovoltaic double-skin façade has provided. The system has been suggested as a retrofit measure for an existing building in Tehran. The effect of thermal performance has been analyzed through computer-assisted developed code using engineering equation solver softwa...

This paper aims at façade reconstruction for subsequent enrichment of LOD2 building models. We use point clouds from dense image matching with imagery both from Mobile Mapping systems and oblique airborne cameras. The interpretation of façade structures is based on a geometric reconstruction. For this purpose a pre-segmentation of the point cloud into façade points and non-façade points is nece...

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...
