NCIDQ IDFX/IDPX EXAM 2025
QUESTIONS AND ANSWERS
What two things must a designer know about space before the necessary number of exits can
be determined? - ANS Before a designer can determine how many of these are needed, both
the floor area and the occupancy group must be known.
What are the four stages of a product's life cycle? - ANS 1. Raw material acquisition
2. Manufacturing
3. Use and maintenance
4. Disposal
What is embodied energy? - ANS This is the energy required by a product or material for its
extraction as a raw material, initial processing, and subsequent manufacture into a finished
product.
in terms of its sustainability, what are the primary advantages and disadvantages of aluminum
as a construction material? - ANS This material has a high potential for recycling, but it
requires a large amount of energy for its manufacture.
What is composite wood veneer? - ANS This is a product made by sliciing readily available,
fast-growing trees into veneers, dyeing the veneers, and then gluing them together to create an
artificial log. The log is then re-sliced to produce a variety of wood veneers.
What is building commissioning? - ANS This is the process of inspecting, testing, starting up,
and adjusting building systems and then verifying that the systems are operating as intended
and that they meet the design criteria.

,What is displacement ventilation? - ANS This is an air distribution system in which supply air
originates at floor level and rises to return air grilles in the ceiling.
What are volatile organic coumpounds (VOCs)? - ANS These are chemicals that contain
carbon and hydrogen and that vaporize at room temperature and pressure.
What are nine common biological contaminents often found in buildings? - ANS 1. mold
2. mildew
3. bacteria
4. viruses
5. mites
6. pollen
7. animal dander
8. dust
9. insects
What are 5 common hazardous materials found in existing buildings? - ANS 1. Asbestos
2. Vermiculite
3. PCBs (polychlorinated biphenyls)
4. Lead
5. Radon
What is adaptive reuse? - ANS This is the practice of reusing existing buildings and materials
from buildings as much as possible

, What are post-industrial (or pre-consumer) materials? - ANS These are scrap or trim
materials generated in the manufacturing process that have been recoverd or diverted from
solid waste.
What does post-consumer mean? - ANS This adjective describes a material or product that
has served its intended use and has been recovered from waste destined for disposal.
What is programming? - ANS This is the process undertaken before design during which wall
pertinent information about a project is collected and analyzed.
According to the book Problem Seeking by William Pena, what are the five steps in the
programming process? - ANS 1. Establish goals
2. collect facts
3. Uncover concepts
4. Determine Needs
5. State the problem
How does a programmatic concept differ from a design concept? - ANS The first is a
performance requirement that is related to general methods of solving a problem or satisfying
a need.
The second is a specific physical response that is an attempt to satisfy the first.
In terms of the programming process, what are the three components of flexibility? - ANS 1.
Expandability
2. convertibility
3. Versitility
What four types of information should be included in every programming document? -
ANS 1. The client's goals and objectives
