2026 VERIFIED QUESTION–ANSWER
COLLECTION
◉ A solid, hard material produced by combining Portland cement,
aggregates, sand, water and sometimes additional mixtures.
Answer: Concrete
◉ The difference between the indoor temperature in winter and the
outdoor design temperature in winter. The design temperature
differential or design range is used in calculating the space heating
requirements of a dwelling unit under the engineering-based
methodology.
Answer: Design Temperature Differential
◉ The finish board covering the edges of rafters and eaves.
Answer: Fascia
◉ The lowest, widest part of the foundation that distributes the load
over a broad area of the soil.
Answer: Footing
,◉ The lower part of a building, which transfers structural loads from
the building to the soil.
Answer: Foundation
◉ The energy needed to warm outside air leaking into a building
through cracks around doors, windows, and other areas.
Answer: Heat Loss
◉ Energy radiated or transmitted as rays or waves, in the form of
particles.
Answer: Radiant Heat
◉ Member of a roof structural frame that supports the sheathing
and other roof loads.
Answer: Rafter
◉ Steel bar used to reinforce concrete.
Answer: Rebar
◉ The numerical value used to indicate the resistance to the flow of
heat.
Answer: R-Value
, ◉ The plate placed at the bottom of a wall.
Answer: Sole Plate
◉ In roofing, 100 square feet of roofing material.
Answer: Square (Quantity of Shingles)
◉ The maximum stress a material subjected to a stretching load can
withstand without tearing.
Answer: Tensile Strength
◉ The process of heat transfer through a solid by transmitting
kinetic energy from one molecule to the next.
Answer: Thermal Conduction
◉ Heat transmission by the circulation of a liquid or a heated gas or
air.
Answer: Thermal Convection
◉ Heat loss/gain resulting from the conduction of heat through the
building envelope.
Answer: Transmission Load
