Correct answer: Transformer

Transformers use electromagnetic induction between primary and secondary coils to change voltage levels from utility transmission voltages to building service voltages.

Question 88: What does 'FAR' (Floor Area Ratio) measure in zoning regulations?

The ratio of building height to street width
The percentage of a site covered by impervious surfaces
The ratio of total building floor area to the area of the site (Correct answer)
The front yard setback as a ratio of lot depth

Correct answer: The ratio of total building floor area to the area of the site

FAR is calculated by dividing the total gross floor area of all building floors by the total area of the site.

Question 89: In site grading, a '2% minimum slope away from the building' is required primarily to:

Direct surface water away from the foundation (Correct answer)
Meet zoning requirements for lot coverage
Provide accessible routes for pedestrians
Accommodate underground utility placement

Correct answer: Direct surface water away from the foundation

Grading at least 2% away from the building ensures surface water drains away from the foundation, preventing water infiltration and moisture problems.

Question 90: What is the purpose of an 'energy model' in sustainable building design?

To simulate a building's energy performance using software to predict consumption and optimize design decisions (Correct answer)
To document the building's energy systems for code compliance only
To calculate the payback period for solar panel installation
To create a physical scale model of the building's mechanical systems

Correct answer: To simulate a building's energy performance using software to predict consumption and optimize design decisions

Building energy modeling uses software (such as EnergyPlus or eQUEST) to simulate heating, cooling, lighting, and plug loads, allowing designers to compare design alternatives and predict energy use.

Question 91: What is the purpose of a moment frame in structural engineering?

To resist lateral loads through rigid beam-column connections (Correct answer)
To provide a path for vertical loads to skip over openings
To distribute tributary loads to footings
To resist gravity loads only

Correct answer: To resist lateral loads through rigid beam-column connections

A moment frame resists lateral forces through bending in beams and columns connected with moment-resisting (rigid) joints.

Question 92: Which movement is associated with the phrase 'form follows function'?

Modernism (Correct answer)
Art Nouveau
