Zusammenfassung (Englisch)

Early design decisions with regard to building facade characteristics play a significant role in the resulting building's thermal performance. In this context, external metal mesh screens - used as a permanent second facade skin - represent a rather new shading alternative, particularly in non-residential buildings. It has been suggested that products of this kind can filter excessive incident solar radiation while maintaining the transparent quality of facade. Given the multifaceted implications of this shading device for building energy performance, a detailed simulation-based study was undertaken to evaluate the impact of metal mesh screens on annual energy demand for heating, cooling, and electric lighting in different European climate zones. To examine this shading technology in a comprehensive manner, possible design variations were considered in terms of mesh screen translucency, window to wall ratio, and facade orientation. In addition, the thesis explored the feasibility of using such a shading strategy, along with suitable ventilation scenarios, to provide passive cooling during summer. Toward this end, a number of existing approaches to simulate metal shade screens were examined, identifying their capabilities and limitations. Subsequently, a typical office space was modelled in three European locations, taking local building construction standards into account. The results of this study can help planners in their choice of the appropriate shading strategy and provide recommendations for the application of metal mesh screens according to the climatic and architectural criteria.
