The Influence of Wind Velocity and Wind Distribution on the Double Skin Façades with Different Width Corridors in DSF Cavities | Chapter 1 | New Ideas Concerning Science and Technology Vol. 13
The
building facade is critical to achieving thermal comfort and energy
conservation. A Double Skin Facade (DSF) is a two-layer envelope system with an
external and internal layer that contains a buffer space for controlled
ventilation and solar protection. Transparency and the use of glass have become
appealing facade options in architectural design as a result of technological
advances. Glass facades on buildings can provide outdoor views, an abundance of
natural light, and the potential for natural ventilation. Double skin façades
(DSF) are architectural elements that are becoming more popular in modern
buildings. They were created as an alternative technology.to improve the
thermal performance of conventional fully glazed buildings. Also they have been
widely used as a way to reduce the thermal instability of inner spaces caused
by the growing use of large glazed areas in buildings. This concept has
provided the possibility of improved sound insulation, preheating air for
ventilation, and protection of solar shading in urban areas. DSF’s can achieve
reduction of winter heating requirements. However, when the building is under
summer conditions or located in moderate or hot climates, heat gains are
predominant and the cost of cooling becomes a major issue. The improvement of
the system is necessary when working under hot climatic conditions.This is
especially true when the façade must function in either extreme or moderate
summer conditions. The thermal overheating characteristics of a specific type
of DSF in various configurations, as well as their practical control, have not
been subjected to systematic experimental and computational investigations.
Previous research suggested that using ventilated facades contributes to energy
savings from indoor thermal gains. The use of a ventilated channel lowers
temperatures in the facade, but indoor thermal conditions must be evaluated in
relation to this.as part of the system's compliance with building requirements,

study attempts to assess the indoor thermal comfort of a mechanically
ventilated building with a DSF configuration. The purpose of this research is
to determine the effect of wind velocity and wind distribution on mechanically
ventilated buildings with DSF configurations, in order to determine whether a
DSF configuration will provide better thermal comfort through natural
ventilation. Another goal of this research is to look into the performance of a

corridors with double skin facades were analyzed using the CFD program in this

comfort indices, PMV and PPD values, were calculated in both FloEFD and Design
Builder.
