Lighting Design as a Universal Design Strategy to Support Functional Visual Environments

Area of Science:

• Architecture
• Environmental Design
• Human-Centric Lighting

Background:

• Light is fundamental to perceiving the environment and essential for daily living.
• Aesthetic and functional lighting conditions are crucial for everyone, particularly for visually and hearing-impaired individuals to ensure independence.
• Current lighting regulations often prioritize quantitative measures (e.g., light levels, uniformity) which are insufficient for users with specific needs.

Purpose of the Study:

• To analyze Danish regulations concerning lighting design in the context of Universal Design.
• To explore how lighting design strategies can support the specific needs of users, guided by accessibility guidelines.
• To bridge the gap between quantitative and qualitative aspects of lighting design for successful Universal Design.

Main Methods:

• Review of existing research on lighting for visually impaired individuals.
• Analysis of Danish lighting regulations and Universal Design principles.
• Discussion of lighting design theories by Richard Kelly, William M. C. Lam, and Hervé Descottes.
• Examination of accessibility guidelines from The Danish Association of the Blind.

Main Results:

• Quantitative lighting aspects alone do not meet the needs of all users.
• A holistic approach integrating qualitative factors (aesthetics, visual stimulation) with quantitative measures is necessary for effective Universal Design.
• Classic lighting design theories offer valuable frameworks for creating visually supportive environments.

Conclusions:

• Successful Universal Design in the visual environment requires a synthesis of quantitative and qualitative lighting strategies.
• Lighting design must consider the diverse needs of users, including those with visual impairments, to promote self-reliance and well-being.
• Adherence to Universal Design principles, informed by user guidelines and established theories, enhances the functionality and aesthetic quality of the built environment.
