A Parametric Design Method for the Lighting Environment of a Library Building Based on Building Performance Evaluation

Abstract

The lighting conditions of a library directly affect the users’ spatial experience, with glass curtain walls being widely used in the design of library skins. Although glass curtain walls have been extensively adopted, they increase indoor sun exposure and glare. Considering sunlight duration and radiation as the design basis, this study employs the Rhino and Grasshopper parametric platforms to parametrically design a library with a dynamic shading skin. Specifically, our design utilizes modular shading components that can change depending on the simulated sunlight data at different times. Additionally, a new optimal design strategy has been developed to enhance the environmental lighting performance of the library. The simulation results highlight that the indoor environmental lighting performance, under dynamic epidermal shading and based on sunlight duration data, is better for east–west, north–south, and east–west orientations on the summer solstice and the winter solstice. Meanwhile, the indoor environmental lighting performance, under dynamic epidermal shading based on daylight radiation data, is better for north–south orientation on the winter solstice. Overall, this study uses parameterization to integrate building simulation and architectural design to improve a building’s lighting performance.

Factors Influencing Academic Library Design in Universities

“…Considerations like size, orientation, energy efficiency, and technological advancements play crucial roles in modern library architecture. Other findings include that of Liu, Han, Yan, and Ren (2023) who found that factors influencing library design include sunlight duration, radiation, and dynamic shading components. Parametric design methods optimize lighting performance based on these factors for enhanced user experience.…”

A Critical Review of Lighting Design and Asset Management Strategies. Illuminating Practices and Lessons Learned for Swedish Public Libraries

“…1) Designing with high-precision simulation tools has become a prevalent trend in digital assisted lighting design. Although along with the prosperous development in 3D modelling after 2018, there has been an increase in the use of 3D modelling software, for lighting design research [8]- [11]. Here still requires a more dynamic bilateral information exchange between the physical asset and the virtual asset to provide detailed environment and boundary parameter inputs.…”

“…Even multi-purpose simulation tools occupied half the popularity in previous studies, but they were mainly geared toward a specific use (thermal, energy and lighting simulation) without information exchange within all modules of a simulation system, and individual case studies required multiple instantiation efforts. Along with the prosperous development in 3D modelling after 2018, there has been an increase in the use of 3D modeling software, specifically Rhino and its-based plugins, for lighting design research [8]- [11]. These plugins are based on the RADIANCE engine and have similar features that enhance the understanding of how the built environment interacts with the surrounding climate and enable the optimization of lighting design for energy efficiency, environmental sustainability, and human factors such as visual comfort, circadian rhythm, and well-being.…”

Evaluation of Design Parameters for Daylighting Performance in Secondary School Classrooms Based on Field Measurements and Physical Simulations: A Case Study of Secondary School Classrooms in Guangzhou

“…By altering WWR, the amount of daylight entering the interior can be adjusted, thus affecting indoor illuminance [20]. Increasing facade shading can reduce the amount of daylight entering the interior, thereby lowering the DGP value [21]. Ensuring sufficient indoor light when adjusting both windows and blinds as necessary can prevent overheating while conserving energy [22].…”
