Proposal of a façade design approach for daylight performance determination in buildings

Abstract

Daylighting is a key component for incorporating visual comfort conditions and reducing energy consumption in buildings. In order to assess daylight potential in the building design phase, diverse performance metrics are developed and are being used in building design phase. These metrics are also integrated into several dynamic lighting simulation algorithms so architects, lighting designers or façade consultants can practically determine the daylight performance of designated façade alternatives in terms of daylight availability, compare design variants and perform necessary revisions during the building design phase. This study deals with proposal of a façade design process in terms of daylight performance determination and aims to describe current daylight metrics that can be used for façade design and applications. Proposed process consists of determination stages based on daylight illuminance, control of glare and view out conditions. With the implementation of this process to façade design, it is possible to provide visual comfort conditions and minimise lighting energy efficiency in buildings.

Impact of Window Design on Dynamic Daylight Performance in an Office Building in Iran

“…The evaluation of daylight performance by utilizing advanced daylight simulation software should be considered for the building in the early stages of the design process [3]. Thus, the Ladybug and Honeybee plugins for Grasshopper 3D, a graphical algorithm plug-in for Rhinoceros, have been used to analyze dynamic daylight performance.…”

“…Therefore, it is a significant parameter in window design and a potential passive solution to improve energy efficiency and visual comfort, particularly in office buildings [2]. Daylight performance analysis and incorporation of the findings with the building façade design process can ensure the effective use of daylighting in buildings [3]. Daylight performance metrics are divided into two categories including static and dynamic that are based on the analysis period (point-in-time vs. annual) and sky model (standard vs. climatebased) [4].…”

A iluminação natural no projeto de arquitetura: revisão sistemática da literatura

“…Daly (2014) desenvolveu uma metodologia que analisa a fachada e divide-a em variáveis e valores, alocando automaticamente as aberturas com o objetivo de atender à certificação LEED (Leadership in Energy and Environmental Design). Yilmaz (2016) introduz um método de design de fachadas que é usado para a determinação do desempenho da luz do dia orientando as decisões de projeto.…”

A Holistic Decision Support Tool for Facade Design

“…Sentop et al [3] propose a catalogue to be used for noise control of exterior walls, whileŞener Yılmaz [4] has a proposal for a facade design approach which considers daylighting performance. Erdemir Kocagil and Koçlar Oral [5] examine the effect of building envelope and form on cooling performance in a hot-dry climate zone.Şahinoglu [6] evaluates the effect of shading elements on the thermal and visual performances of the window.…”
