What is the acceptable Light Reflectance Values (LRV) for ceilings? - CORRECT
ANSWER 0.8 - 0.9
What term refers to minimum levels of natural lighting in spaces? - CORRECT
ANSWER Spatial daylight autonomy
Annual sunlight exposure places a cap on inappropriately high levels of sunlight.
Which of the following is NOT a benefit of automated controls for shading devices: Ensures the
systems operate as intended; Helps regulate circadian cycle; Contributes to energy use reduction;
or Contributes to comfort without disrupting occupants from other tasks? - CORRECT
ANSWER Helps regulate circadian cycle
The circadian rhythm is an internal clock in humans and animals that synchronize physiological
functions on a cycle of what duration? - CORRECT ANSWER 24 hours
On buildings with greater than 40% window-to-wall ratio as measured from exterior elevations,
what control measure is required to earn Feature 63 Daylighting Fenestration? - CORRECT
ANSWER External shading
In an existing retail center under renovation and pursuing WELL Certification, 50% of the
windows are being replaced. The project team is tasked with reducing glare in the building.
Where is the most appropriate location for a film of micro-mirrors on the window? - CORRECT
ANSWER Glazing over 7ft AFF.
, In order to minimize glare at workstations and desks, bare lamps and luminaire surfaces more
than 53 degrees above the center of view must have luminances of what intensity? - CORRECT
ANSWER Less than 8,000 cd/m2 per Feature 55 Electric Light Glare Control
What specific part of the body acts as a main internal clock that synchronizes with clocks in
peripheral tissues and organs? - CORRECT ANSWER Suprachiasmatic nucleus
Which Feature addresses the maximum luminance allowed for light fixtures above 53 degrees
above the center of view? - CORRECT ANSWER Feature 55 Electric Light Glare Control
A new university dorm is being constructed in Rome. The project team is pursuing Feature 60
Automated Shading and Dimming Controls. Which windows need to have shading devices that
automatically engage when light sensors indicate that sunlight could contribute to glare at
workstations? - CORRECT ANSWER All windows larger than 6 ft2
In an office building new construction project, consideration of the brightness contrast between
which two areas is NOT required? - CORRECT ANSWER Main lobby and the exterior
Feature 53 Visual Lighting Design, Part 2 Brightness Management Strategies, does not refer to
contrast between indoor and exterior areas.
Luminanace balance is required between main rooms and ancillary spaces.
Luminanace balance is required between task surfaces and immediately adjacent surfaces,
including adjacent visual display terminal screens.
What is the ideal lighting type for building occupants? - CORRECT ANSWER Diffuse
daylight
An average lighting intensity of at least 215 lux (20 fc) is required in which space type? -
CORRECT ANSWER Workstations and desk areas
Feature 53 Visual Lighting Design, Part 1 Visual Acuity for Focus, refers to light level
requirements at workstations or desks. In these areas, ambient lighting must be able to maintain
an average light intensity of 215 lux (20 fc) or greater.
