Question 1

Concrete floor floating construction provides good insulation against __________ sounds.
A)impact
B)air-borne
C)water-borne
D)structural

Accepted Answer

Concrete floor floating construction is specifically designed to reduce impact sounds, which are noises that come from direct contact with the structure, such as footsteps or dropping objects on the floor.

Question 2

If the direction of the wind is at 90° to one of the faces, positive pressure will be produced on __________
A)windward face
B)leeward face
C)two windward faces
D)two leeward faces

Accepted Answer

When the wind blows directly against a surface, such as a building face, it creates a positive pressure on that surface because the wind is pushing against it. This surface is known as the windward face.

Question 3

Ventilation arising from the temperature difference between outside and inside takes place due to ____________ effect.
A)stack
B)stark
C)zeeman
D)spark

Accepted Answer

Stack effect is the movement of air into and out of buildings, chimneys, flue-gas stacks, or other containers, resulting from air buoyancy. Buoyancy occurs due to a difference in indoor-to-outdoor air density resulting from temperature and moisture differences. The result is either a positive or negative buoyancy force. The stack effect helps drive natural ventilation and infiltration.

Question 4

The maximum rate of air change is __________
A)30 per min
B)30 per hour
C)60 per min
D)60 per hour

Accepted Answer

The maximum rate of air change is typically measured in air changes per hour (ACH), and 60 per hour is a common maximum rate for certain applications.

Question 5

The general temperature difference between inside and outside of a room is not more than ____________
A)3°c
B)5°c
C)6°c
D)8°c

Accepted Answer

The answer of The general temperature difference between inside and...
