A daylighting device may offer you a great alternative to a traditional skylight. Daylighting devices can put sunlight into places that you could never dream of brightening with a standard skylight. Take our quiz now and see how you rate among daylighting device experts.
What is the basis for our attraction to bringing more sun into homes and offices?
Bringing more sunlight into a home increases positive ions and purifies air.
Bringing more sunlight into a home reduces the need for artificial lighting.
Bringing more sunlight into a home can reduce energy usage by 38 percent.
What incentive does a business or education facility have to pay extra for installation of devices to admit more sun?
New health and safety laws require businesses to increase sunlight by 30 percent within two years.
The Environmental Protection Agency is offering tax credit incentives to business that increase sunlight.
Sunlight helps to keep employees and students happy and motivated.
What is a significant shortcoming of regular windows and skylights?
Windows and skylights provide varying levels of sunlight by season and time of day.
Windows and skylights get dirty and require constant cleaning to give the most benefit.
Windows and skylights require expensive blinds or curtains to control levels of sunlight.
What is a daylighting device?
A daylighting device is a special fluorescent tube or bulb designed to simulate natural daylight.
A daylighting device is another name for the special booths found in tanning salons.
A daylighting device is an object designed to collect, transmit and emit daylight into a building.
What is a major difference between a skylight and a daylighting device?
Directing sunlight with a daylighting device is more flexible than with a traditional skylight.
A daylighting device does not require a hole in the roof for installation.
A daylighting device can only be installed during construction of a roof and skylights can be installed any time.
What option is unique to a daylighting device versus a traditional skylight?
A daylighting device filters out harmful UV rays and a skylight does not.
A daylighting device gives you all the benefits of sunlight without the usual heating affect.
The collector of a daylighting device can be positioned on a roof to collect sun all day long.
With the possibility of intense sunlight from a daylighting device for all of the daytime hours, how do you control the amount of sunlight in a room?
Daylighting devices employ shades in the same way skylights do.
Daylighting devices can be equipped with an optional electric butterfly dimmer.
Daylighting devices come with an adjustable metal louver system similar to air conditioning vents
How many basic parts are there to a standard daylighting device?
How does a daylighting device manage to bring the light from the roof into any room?
via a series of adjustable prisms
via a series of polished glass rods
via a series of lenses and mirrors
What would you see on the roof of a home where a daylighting device is installed?
You would see a motorized tube positioned at a 45-degree angle with a lens on one end that tracks the sun.
You would see an oblong glass object about the size and shape of a football standing on end.
You would see a small glass dome or pyramid sitting on top of a metal tube.
Once the sun has passed through the lenses, how is it conveyed to the emitter located in a room?
via a straight polished metal tube installed at a maximum 45-degree angle
via solid polished metal tubing with allowance for angles up to 90 degrees
via special flexible polished tubing made to go around obstructions
What is an issue with sunlight transmission that affects the maximum efficiency of a daylighting device?
Heat generated in the transmission tube reduces the light transmitted proportionally.
The longer the transmission section is the lower the light intensity will be when it reaches the emitter.
Sunlight transmission attenuation is inversely proportional to the tube length.
What is the maximum distance that the manufacturer recommends from collector to emitter for a daylighting device?
What is a common feature incorporated in the emitter of a daylighting device?
emitters often contain diffusers
emitters often contain UV filters
emitters often contain fans
What is a reason that sun entering a home via a daylighting device can help people feel happier and healthier?
Exposure to sunlight has been proven to increase levels of vitamin E and associated antioxidant effect.
Exposure to sun has been proven to increase levels of free radicals and vitamin C.
Exposure to sunlight has been proven to increase levels of serotonin and vitamin D.
What is the name of a common disorder that affects people living in the northern hemisphere in the winter?
chronic bronchial disorder
seasonal affective disorder
seasonal chronic sinusitis
Is the installation of a daylighting device a do-it-yourself kind of project?
Installing a daylighting device is only for experienced roofers.
Almost anyone can install a daylighting device.
Installing a daylighting device is best left to a professional.
What is the unit of measure used to rate the amount of heat from sunlight that a daylighting device will block?
thermal blocking coefficient
solar heat gain coefficient
Is it possible for people that live in warm climates to suffer from SAD?
No, only dark winter days trigger symptoms of SAD.
Only in rare instances when they also suffer from low levels of vitamin D and iron.
