ShareSummary
Daylight plays an important role in building design. It affects occupant?s activities, reduces energy demand, and supports human health. However, most daylighting simulation software does not capture the behaviors of occupants and of dynamic shading. DAYSIM is the only simulation software that calculates dynamic shading devices using a lightswitch model, but it has limitations. It is unable to use other automated control algorithms or capture occupant?s behavior. It is also unable to simulate advanced shading devices that can only be described by a bidirectional scattering distribution function, such as light redirecting films. In this paper, a new framework is developed based on three-phase method in Radiance to enable an accurate annual daylighting simulation in a room equipped with dynamic shading devices and/or daylight redirecting devices. Two case studies are carried out using the Hanoi climate to demonstrate the capability of the framework. The framework can flexibly run any automated control algorithms and any dynamic behaviors by occupants, which allow future smart building applications. In the future, the framework will be expanded to run five-phase method in Radiance and a user-friendly interface will also be developed.
