Study Notes
Daylighting Analysis and Design
- Daylighting in offices improves performance, increasing productivity by 7-12%.
- Daylighting in hospitals reduces the need for pain relief by 30%, making recovery faster and improving patient spirits.
Glare and Contrast
- Glare is caused by excessive contrast between an object and its background.
- Two methods for avoiding glare: sensitive interior design and daylight light controls.
Theory and Perception of Light
- Luminous flux is the amount of light flowing through a space, measured in lumens per unit area.
- Lux is the unit of measurement for luminous flux, equal to lumens per square meter.
- Footcandles are another unit of measurement for luminous flux, equal to lumens per square foot.
- Luminance is the light reflected from a surface, measured in candelas per square meter.
