In cooler climates, the HVAC system can employ ___________ to
capture exhausted heated air and return that energy to augment the
building's heating system. - ✔✔✔ Correct Answer > Energy Recovery
Vents
SAA (sound absorption average) - ✔✔✔ Correct Answer > and NRC
are similar, with higher values indicating better sound absorption.
Sound absorption is measured between 0 and 1, with materials used to
absorb sound rated .5 or greater. That means that the material absorbs
approximately half of the sound and reflects half.
Which part of the HVAC system transports heated or cooled air to
interior spaces for supply and return? - ✔✔✔ Correct Answer >
Ducts
NFPA 101 - ✔✔✔ Correct Answer > Specifies requirements for flame
detection alarm systems or radiant energy-sensing systems.
,Fire Containment - ✔✔✔ Correct Answer > Limits the spread of a fire
through compartmentalization. The aim is to contain a fire and limit its
spread. The first goal of containment is to allow occupants to escape
the building. Next, containment protects the unaffected parts of the
building or adjacent buildings.
Articulation class is (AC) - ✔✔✔ Correct Answer > nother measure of
the finished ceiling's absorption and reflection of sound, but specifically
affects speech clarity in an open office environment.
A slot air diffuser should be used when? - ✔✔✔ Correct Answer >
The appearance of the air distribution device needs to be minimized
and or when the available space does not accommodate a square air
diffuser.
Displacement Ventilation - ✔✔✔ Correct Answer > is an air
distribution system in which supply air originates at the floor level and
rises to return air grilles in the ceiling.
What type of system would be best for an open office plan so the
heating and cooling for each workstation could be individually
controlled? - ✔✔✔ Correct Answer > All-Air System
Fire suppression - ✔✔✔ Correct Answer > Uses life safety equipment
for fire detection, suppressing smoke and flame, alarms, and
extinguishers.
,Fire Detection - ✔✔✔ Correct Answer > Systems can use a
combination of computers, video detection, and remote controls.
Detectors can be programmed to detect more than one sign of fire to
prevent unnecessary false alarms. Other programs will require more
types of alarm verification.
Smoke detection - ✔✔✔ Correct Answer > Smoke detection is
required by code for Institutional, High Hazard, and most Residential
occupancies and high‐rise buildings and ambulatory healthcare
facilities. NFPA 72 sets specific requirements for installation, location,
and maintenance for smoke detection systems.
A smoke detector can be ceiling mounted or wall-mounted, usually
____ inches (102 mm) from the wall/ceiling intersection to prevent air
currents from bypassing the smoke detector. - ✔✔✔ Correct Answer
> 4"
Heat Detectors - ✔✔✔ Correct Answer > Are better for larger spaces
or fires with more flames. Heat detectors can pinpoint the location of
any temperature change for a specific location or a designated area.
Heat detectors can be paired with smoke detectors to avoid false
alarms. For more sensitive areas, detecting either smoke or heat can
activate the fire protection system.
, Carbon Monoxide Detectors - ✔✔✔ Correct Answer > Carbon
monoxide detectors are required outside each separate sleeping area in
new construction. If a fuel‐burning device like a gas fireplace is in the
bedroom, a detector or alarm must also be included.
Strobes - ✔✔✔ Correct Answer > All public use and common areas
typically require strobes:
Restrooms
Corridors
Lobbies
Meeting rooms
Break rooms
Examination rooms
Classrooms
A certain percentage of the units must have visual alarms placed in
specific locations and heights above the floor and certain distances
apart in occupancies with multiple sleeping units. Refer to ADA
Standards and ICC A117.1
Visible alarms are not required in exits such as stairwells because of
potential distraction and tripping hazards.
Sprinklers - ✔✔✔ Correct Answer > International Building Code (IBC)
requires sprinklers in buildings over 75 ft (22860 mm) high. For open-
wood joist ceilings, the area drops to 130 ft2 (12.1 m2). Maximum
spacing between sprinkler heads is 15 ft (4.6 m) for the 225 ft2 (20.9
