User behavior analytics (UBA) is the tracking, collecting, and assessing of user data and activitiesusing observation and monitoring systems for the purpose of finding existing usage patterns,trends, and relationships to better predict future user and occupant behavior.
Which of the following existing conditions influencesthe space plan of an interior design project?
A. all of these
B. an undesirable view
C. location of structural elements
D. location of plumbing
A. all of these
Several aspects of existing conditions
can influence the space plan of an interior design project.Evaluation of existing conditions as a part of site analysis can occur as early as pre-design.
Depending on the nature of the project not all will apply: These include size of existing space, ornate millwork, location of plumbing, an undesirable view, and the location of existing columns, and loadbearing walls.

A. rectified photography
B. sterophotogrammetry
C. orthophotography
D. convergent photogrammetry
D. convergent photogrammetry
Convergent photogrammetry
entails using photographs from different angles to create a three-dimensional model. This process takes a long time but is relatively inexpensive.
Stereophotogrammetry entails superimposing one photograph of a building over another, creating an image that can easily be converted into a 3-D depiction. This process requires special software and equipment.
Rectified photography is a technique for producing scalable images of building façades.
Orthophotography is a technique for aggregating digital photographs into a single, three-dimensional image, using sophisticated computer programs.
Which scenario is best suited to hand measuring?
A. measuring residential design projects
B. measuring large, but simple spaces

An interior designer has been retained for a building project that is currently being planned by an architect. On the second floor of the building, slate flooring over a concrete subfloor is being used. What type of installation should ideally be designed for?
A. a thick-set application using a cleavage membrane
B. a standard thin-set application
C. a 1/2 in layer of mortar with the stone dry-set on top
D. a bonded thick-set installation
A. a thick-set application using a cleavage membrane
Slate does not have a uniform thickness and a concrete subfloor above grade may deflect and Cause cracking. If a subfloor deflects or moves in some way, a thin-set tile installation will probably develop cracks, thus the best installation is a thick-set method with a
cleavage membrane
The thick-set or full mortar bed installation method allows the tile setter to adjust the bed according to the exact thickness of each stone.
Using which of the following would be the best wayfor a designer to reduce heat loss and heat gain in space?

Which window treatment is best for controlling Blinds/windowlighting in an open office area?
A. Venetian blinds
B. pleated shades with blackout liner
C. roller shades with 10% opacity
D. drapery with solar liner
A. Venetian blinds
Horizontal blinds also known as
Venetian blinds, allow for the most flexibility to control lighting, allowing for more or less light control depending upon how the louvers are tilted. Miniblinds are horizontal blinds with smaller width louvers
In developing a signage system for a health care clinic, the designer decides that the room identification signs should be mounted perpendicular to the wall near the door to each room.

Palm wood flooring isavailable in 3⁄4” x 3” (19mm x 76mm) wide strips with tongue and groove edges like those ofstandard strip flooring. It is harder and more stable than maple, red oak and white oak.
What is NOT true about the COF (Coefficient ofFriction) measurement?
A. The lower the COF, the less slippery it is
B. The COF is measured in a resting position
C. The COF is used on wet and dry surfaces
D. The ADA only recommends a COF value
A. The lower the COF, the less slippery it is
COF(coefficient of friction) is measured while static and the
DCOF while in motion.
The higher the COF, the less slippery the surface. There are two basic measures of friction:
1.
the static coefficient of friction, which is measured from a resting position
2.
the dynamic coefficient is measured when the two surfaces are in relative motion
The flame-spread rating of wood panel wainscoting must be
A. class B if the wainscoting takes up more than 10% of the wall area
B. based on location and occupancy
C. nothing, because it is not regulated
D. a minimum of Class A
B. based on location and occupancy
Wall interior finishes of wood paneling or wainscoting are regulated in the same way as other wall and ceiling finishes per IBC. The minimum flame-spread rating depends on the occupancy and the location in the building.
