Brotas, Luisa and Rusovan, Danijel (2013) Parametric daylight envelope. In: PLEA 2013 – 29th Conference: Sustainable Architecture for a Renewable Future, 10-12 September 2013, Munich, Germany.
With the increased sophistication of digital tools for assessing daylight and energy in buildings, a great potential exists for optimizing the performance of contemporary building façades. A holistic approach can promote both visually and thermally comfortable spaces, reduce glare and lead to buildings that consume less energy. This is pivotal in addressing environmental awareness and tackling climate change while achieving high user satisfaction. This paper presents a study of an optimised facade commonly found in service buildings. Four types of building envelopes are simulated in terms of climate-based metrics, glare and energy consumption. The first two types have 40% window-to-wall ratio (WWR), with one of them having a light shelf. The third and fourth are 100% WWR with one of them having a parametrically driven fixed screen. This study aims to find an optimum solution in terms of daylight and energy use for cooling, heating and artificial lighting for the climate conditions of London, UK by using an integrated daylight and thermal simulation approach.
