Impact of Sun-Shading Devices in Daylight Assessment with Daylight Ratio in Energy Efficiency Building Design
The research presented the correction for daylight calculation under the real sky condition with the Daylight Ratio for the Russian standard in consider impact of horizontal shading devices. In this research, the method for daylight calculating was improved with the proposal of two coefficients Kshad and Kref that consider the influence of the shading device and replaced the approximate factor τ4, which consider the shading in the exits Russian standards. The research also reveals the assessment of daylight in a room under an intermediate sky is characterized by a reflection of direct sunlight. The results show that a significant effect from the reflection coefficient when the first reflecting surface has a high reflectance and sky condition with high diffuse radiation. Correcting the shading and reflecting coefficients shading device under the Intermediate Sky was associated with the availability of Climate Based Daylight Modelling. With this approach, it is possible to complete the criteria for a dynamic daylight assessment, by combining an artificial lighting system with a touch mode, it will guarantee the requirements of indoor illuminance and energy efficiency.
