Additional learning units will be posted when confirmed
Foot-candles, watts and lumens are inadequate terms for describing energy-effective lighting, but these terms are often also the basis of energy codes. In this session, a vision scientist, lighting designer and energy code consultant describe how lighting quality is incorporated into California's Title 24 building energy code and Title 20 appliance energy efficiency standards. Attendees will learn about lighting quality elements within the code and how to use these metrics to create high-quality, code-compliant lighting projects. Topics include how to understand lighting quality metrics and when and how to claim lighting power allowances for quality options within the code.
- Understand key metrics of lighting quality (color fidelity, color constancy, color saturation, IEEE and NEMA flicker metrics, contrast ratio).
- Understand key elements of visibility (illumination, contrast, adaptation, color discrimination).
- Understand basis and application of LPD requirements in Title 24 and ASHRAE 90.1.
- Understand quality options within the code through an overview of lighting quality elements in California's Title 24 (building code) and Title 20 (appliances standard).
