Light and Human Health
What type of lighting is designed to support human circadian rhythms by mimicking natural daylight patterns?
What is human-centric lighting?
What is the term for the depth of a room that can be effectively lit by daylight entering from the side?
What is daylight zone?
Which organization provides the standard practices for lighting, such as RP-8 for roadway lighting?
What is the Illuminating Engineering Society (IES)?
What is the term for the ability of the eye to adjust when moving from a bright outdoor space to a dim indoor space?
What is dark adaptation?
What lighting technology significantly reduces energy consumption compared to traditional incandescent bulbs?
What is LED (Light Emitting Diode)?
This type of lighting can impact melatonin production and influence sleep cycles.
What is blue light?
These types of architectural shading system are used to control sunlight entering an occupied space - user adjustable.
What are blinds or shades?
This energy code sets minimum lighting energy requirements for buildings in the U.S. A:
What is the International Energy Conservation Code (IECC)?
This process occurs when the eyes adjust to higher light levels after moving from a dark environment.
What is light adaptation?
This metric indicates the amount of visible light produced per unit of energy consumed by a light source.
What is luminous efficacy?
Exposure to insufficient light during the day can lead to this condition, affecting mood and energy levels at certain times of the year.
What is Seasonal Affective Disorder (SAD)?
Which type of daylighting control adjusts for varying levels of daylight throughout the day?
What is dynamic daylight control?
Which document outlines the standards for sustainable building practices, including efficient lighting?
What is LEED (Leadership in Energy and Environmental Design)?
Which two photoreceptor types in the eye are responsible for adapting to different light levels?
What are rods and cones?
Which lighting control strategy reduces energy consumption by dimming lights in response to sufficient daylight?
What is daylight harvesting?
Which part of the brain is responsible for regulating the circadian rhythm, influenced by light exposure?
What is the suprachiasmatic nucleus?
What architectural feature is used to maximize daylight penetration while minimizing glare?
What is a light shelf?
This lighting code ensures proper illumination for emergency egress in buildings.
What is NFPA 101, Life Safety Code?
In nighttime conditions, this type of vision is dominant and does not allow for color perception.
What is scotopic vision?
This term describes lighting systems that turn off or reduce output when no one is in the area.
What is occupancy control?
This hormone, responsible for sleep regulation, decreases in production when exposed to bright light.
What is melatonin?
This daylighting strategy positions windows high on walls to allow deep daylight penetration into a space.
What are clerestory windows?
The acronym “________ 90.1” is associated with this standard that influences lighting energy use in buildings.
What is ASHRAE Standard 90.1?
When both rods and cones are active under moderate lighting conditions, this type of vision occurs.
What is mesopic vision?
A building that generates as much energy as it consumes annually through efficient lighting and other systems is called this.
What is a net-zero energy building?
