简历：
Ling Chen currently works for Eaton Cooper Lighting, a world leading lighting manufacture. She graduated the doctorate degree from Pennsylvania State University, Department of Architectural Engineering in 2017. Penn State lighting graduate program was sponsored by Department of Energy and performs researches on sustainable buildings. Her expertise covers daylighting, photocontrol systems, system performance analysis and simulations, luminaire optics, color science, lighting design, etc. Her graduate research focused on daylight responsive photocontrol system performance.
报告概要:
Introducing daylight into interior spaces is considered good practice to improve productivity and reduce energy consumption. Daylighting applications are more common in educational and commercial buildings with large open spaces. Daylight responsive photocontrol systems were found effectively reducing the energy load by about 40% of the total lighting energy. Shading devices are commonly applied to prevent glare from the sunlight, but introducing shading operation adds complexities to the photocontrol system response.
Daylighting performance is usually evaluated based on annual metrics. Most annual metrics can only be provided by annual simulations. Advanced multi-phase daylight simulation method was introduced to replace the traditional standard daylight coefficient method, recently. By using measured or simulated bidirectional scattering distribution function (BSDF) of the complex fenestration systems (CFS), multi-phase method provides more efficient simulations for CFS and more accurate results for the direct sun. High quality photocontrol systems require proper system setup and commissioning process. The product selection, system layout and the calibration are three keys to the system performance, which require comprehensive and integrated system analysis. Advanced daylight simulation is proved to provide efficient and accurate predictions for comprehensive photocontrol system performance.
