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
