Abstract

The effective use of daylight is a critical design input that increases spatial qualities, sustainability, and energy efficiency targets in buildings. The emerging kinetic architecture concept supports these goals. It also recommends the use of building elements that are suitable for the design of dynamically environment-responsive façades. This study aims to explore the potential of kinetic envelopes for the design of optimal daylight efficient façades. The methodology is based on computational models of kinetic façade patterns applied to a generic building, which are further optimized to reveal the most efficient design. The façade features a modular pattern based on triangles, which, by simple rotation around the vertical axis, provides both daylight control and visual comfort. The results of a parametric analysis of the panel configurations based on daylight metrics, show that the proposed design helped achieving the most effective configuration for daylight savings.

Gün Işığı Performansı için Tepkisel Bir Cephe Sisteminin Parametrik Optimizasyonu

Abstract

Gün ışığının etkin kullanımı, binalarda mekânsal nitelikleri, sürdürülebilirliği ve enerji verimliliği hedeflerini artıran kritik bir tasarım girdisidir. Ortaya çıkan kinetik mimari konsepti bu hedefleri desteklemektedir. Ayrıca dinamik olarak çevreye duyarlı cephelerin tasarımına uygun yapı elemanlarının kullanılmasını önerir. Bu çalışma, optimum gün ışığı verimli cephelerin tasarımı için kinetik cephe sistemlerinin potansiyelini araştırmayı amaçlamaktadır. Metodoloji, en verimli tasarımı ortaya çıkarmak için optimize edilmiş, çalışma kapsamında oluşturulmuş bir binaya uygulanan kinetik cephe modellerinin hesaplamalı modellerine dayanmaktadır. Cephe, dikey eksen etrafında basit bir dönüşle hem gün ışığı kontrolü hem de görsel konfor sağlayan üçgenlere dayalı modüler bir desene sahiptir. Gün ışığı ölçümlerine dayalı panel konfigürasyonlarının parametrik analizinin sonuçları, önerilen tasarımın gün ışığından yararlanma için en etkili konfigürasyonun elde edilmesine yardımcı olduğunu göstermektedir.
