Photovoltaic shading devices (PVSDs) have the dual function of providing shade and generating electricity, which can reduce building energy consumption and improve indoor daylighting levels. This study adopts a parametric performance design method and establishes a one-click simulation process by using the Grasshopper platform and Ladybugtools.
Photovoltaic louver shading (PLS) and lighting control system (LCS) can both reduce energy consumption during building operation, but when used in combination, PLS may reduce indoor daylighting and increase lighting energy consumption, which is not good for the LCS.
The DA of 30% CT photovoltaic glass measuring points over 80% is greater than 55%, which belongs to the acceptable daylighting environment, but the proportion of measuring points with DA less than 55% is more than 10%. To create a better daylighting environment, 40–80% CT photovoltaic glass is a better choice. 3.1.3.
This configuration was based on an existing study, which suggested that the best method to improve daylighting performance is to attach solar panels to a portion of the reflector, allowing for simultaneous power generation and daylighting while ensuring a larger area for power generation than the area designated for daylighting.

Dynamic photovoltaic shading systems (PVSDs) that can automatically adjust PV angles according to solar altitude and azimuth to enhance solar energy utilization, have become an important
Photovoltaic shading devices (PVSDs) have the dual function of providing shade and generating electricity, which can reduce building energy consumption and improve indoor daylighting levels. This study adopts a
Harmonizing Daylight and EquipmentIntegration Maximizing rooftop potential is a crucial strategy in sustainable, low carbon building design, where the integration of energy generation and natural daylighting
Light shelves are a conventional method of daylighting, and numerous studies have explored incorporating solar panels with light shelves to enhance energy efficiency. However, the use of non
Daylighting strategies to achieve net-zero carbon buildings – casestudies In our previous knowledge article, we explored how incorporating strategically placed daylighting can help achieve net-zero
(4) Applying a photovoltaic module can lower the indoor uniformity ratio, which means that the daylighting performance of the light shelf is degraded due to the reduction of the area occupied by
The visible range of photonic energy from the sun can be extracted by using either a passive daylighting system that is associated with the building structure or an active daylighting system. Figure 1
Semi-transparent photovoltaic glass can solve these issues by replacing shading facilities, blocking solar radiation, and generating electricity. This study examines the influence of different types of
IEA SHC Task 61 / EBC Annex 77 “Integrated Solutions for daylighting and electric lighting – From Component to system efficiency” therefore pursues the goal to support and foster the better integration
