Transition Planes for Visual Comfort: Out View with Complex Fenestration System Design at Restaurants in Spain

Abstract

This work deals with daylighting for quality indoor atmospheres, considering building skins. In recent years, almost all retrofit facades of restaurants are highly glazed façades, boosting glare, sun ray absorption and overheating inside. Most of the time, they are not integrated with daylight control; therefore, lighting and out view requirements are not so balanced. Taking into account this daylighting complexity, an alternative façade system is proposed to simulate by Radiance. Previously, perception simulations are compared with measured data, in order to discretize the simulations. In addition, for one point three different view are assessed as: work plane, relation plane and the out plane. Subsequently, two virtual façade models, windows combined by complex fenestration system (CFS) as prismatic film (PF) and highly glazed façade, are tested according to daylighting. For that, three indexes have been used: daylight glare probability (DGP), daylight glare index (DGI) and daylight autonomy (DA). The results show that the proposed complex façade has a good light contribution with less absorption, while maintaining the outside view. In addition, the DGI is needed to test the out plane, because DGP is more suitable for lower luminance; therefore, each visual plane should be assessed regarding different visual comfort conditions, or parameters and methods. Accordingly, the mean DGI result of window combined by CFS is approximately lower in 5% than highly glazed façade. However, the DA of highly glazed is higher in 5%, but the DA of window combined by CFS is enough, above 80%. Definitely, the complex scene at restaurant with the proposed integrated façade system improves light performance and indoor atmosphere.

Research on Graphic Visual Communication Design for User Perception Experience

“…Taking user perception psychology as the basis, combining the indexes of visibility, informativeness, emotional appeal, and work performance in graphic visual communication design with the purpose of reutilization of visual communication design [14][15] and realizing the transformation of the characteristics of graphic visual communication design, we should make the design results have the characteristics of the visual level, the functional level and the demand level [16][17]. In this regard, the utilizable graphic visual design must put the users into specific life situations during the design, explore the demand for reuse of the design, transform the market into practical functions, and reasonably integrate it into the graphic visual communication design [18][19].…”
