A Novel Context driven Critical Integrative Levels (CIL) Approach: Advancing Human-Centric and Integrative Lighting Asset Management in Public Libraries with Practical Thresholds

TL;DR

This paper introduces the Critical Integrative Levels (CIL) approach for managing lighting in public libraries, emphasizing human-centric design by considering visual, physiological, and psychological factors, and utilizing a new metric called MTOE.

Contribution

The paper presents a novel CIL framework that integrates user well-being metrics into lighting management, advancing beyond traditional visual-focused methods.

Findings

CIL improves user experience by balancing visual and non-visual lighting effects.

The MTOE metric effectively quantifies user-light interaction.

Case studies validate the practical application and benefits of CIL.

Abstract

This paper proposes the context driven Critical Integrative Levels (CIL), a novel approach to lighting asset management in public libraries that aligns with the transformative vision of human-centric and integrative lighting. This approach encompasses not only the visual aspects of lighting performance but also prioritizes the physiological and psychological well-being of library users. Incorporating a newly defined metric, Mean Time of Exposure (MTOE), the approach quantifies user-light interaction, enabling tailored lighting strategies that respond to diverse activities and needs in library spaces. Case studies demonstrate how the CIL matrix can be practically applied, offering significant improvements over conventional methods by focusing on optimized user experiences from both visual impacts and non-visual effects.
