ANSWERS | 100% PASS
The five-step process outlined in William Pena's book, Problem Seeking,
suggests that the first step in gathering information about a client's
needs is to establish goals. What is the suggested order of the
remaining four steps?
A. determine needs, collect and analyze facts, uncover and test
concepts, state the problem
B. collect and analyze facts, determine needs, state the problem,
uncover and test concepts
C. uncover and test concepts, state the problem, determine needs,
collect and analyze facts
,D. collect and analyze facts, uncover and test concepts, determine
needs, state the problem - ANSWER ✔✔D.
The suggested order is establish goals, collect and analyze facts,
uncover and test concepts, determine needs and stat the problem.
Establishing goals is a critical first step in the process because it sets the
direction for the other four steps.
According to William Penas book, Problem Solving, all design problems
can be stated in terms of form and which three other factors?
A.) Analysis, synthesis, and function
B.) function, economy, and time
C.) goals, facts, and function
D.) economy, time, and synthesis - ANSWER ✔✔B.
Design problems can be stated in terms of form, function, economy, and
time. Can be broken down further ex: economy can be studied in terms
of initial cost, operating cost, and life-cycle cost.
Which of these types of information regarding a new multipurpose room
in an assisted-living facility would be the LEAST important for the interior
designer to give to the mechanical engineer?
,A.) the ages of the residents in the facility
B.) the types of activities the room will be used for
C.) the maximum number of residents using the room at one time
D.) a copy of the reflected ceiling plan - ANSWER ✔✔A.
Options B and C relate directly to how much heat will be generated and
how much ventilation will be needed in the room, both of which the
mechanical engineer must design for. The reflected ceiling plan will
indicate the room's ceiling type and its lighting design, which the
engineer can use to estimate how much heat will be generated by the
lights. As long as the engineer knows the facilities occupancy type,
occupant age is of little concern.
Apart from being decorative, the primary advantage of using tapestries
in Gothic and Renaissance castles was that they
A. reduced sound reflection
B. minimized drafts
C. raised mean radiant temperatures
D. reduced condensation on walls - ANSWER ✔✔C. Tapestries
served all 4 but their advantage was that they decreased heat loss

, through radiation by covering stone walls with an insulating material.
This, in effect, raised mean radiant temperatures
Interior Spaces often need to be multifunctional or flexible. What are the
three components of flexibility as a programmatic design concept?
A. versatility, convertibility, and grouping
B. expandability, hierarchy, and flow
C. flow, hierarchy, and convertibility
D. convertibility, expandability, and versatility - ANSWER ✔✔D.
convertibility, expandability, and versatility.
CONVERTIBILITY- space's usefulness for different functions through the
conversion of the space.
EXPANDABILITY refers to a space's ability to accommodate growth
through expansion.
VERSATILITY- a space's ability to accommodate a variety of activities.
An inter-designer is researching ergonomic chairs for an office. Which of
the following design criteria is LEASTimportant to consider?
A. DURABILITY
B. Lumbar support
