適應型建築遮陽系統之年日照效能分析

Abstract

None

Daylight increases solar heat gain and causes visual discomfort for occupants, especially when highly glazed office buildings are installed to take advantage of maximum free light and take a stunning view. Therefore, a requirement for designers and architects is how to flexibly design building facades to not only reduce the energy use of buildings while maintaining the level of daylight inside the buildings and bring occupants comfortable. Nowadays, several innovative solutions exist to address the challenge of building a sustainable environment, one of which is the design of automatic shading systems that aim to build sustainable environments through constructing adaptive building façades that adapt to changing climatic conditions. In order to achieve the desired results for facade controls and the annual daylight performance evaluation of the adaptive facade shading system, it is necessary to calculate and analyze data through simulation. Nevertheless, this is a complicated and elaborate job because it requires a lot of technical expertise of construction systems, materials, and computer pieces of equipment requiring constant adjustment of models to test until the goal is reached. As a result, the objective of this thesis is to provide a new framework for annual daylight performance simulation of adaptive facade shading systems based on Ladybug and Honeybee plugins together with Radiance and Daysim that enables accurate simulation of dynamic system and provides the illuminance files for calculating daylight metrics and glare levels. A case study is conducted in an office room in six different states of adaptive facade shading devices and simultaneously control by algorithms based on DGPs glare evaluation and sun position in Taipei Taiwan's climate condition.
