Q

a measure of how easily heat travels through an assembly of materials

Study These Flashcards
A

Overall Coefficient Of Heat Transfer (U)

24
Q

Thermal insulating ability is also measured by the _________ resistance (R):

25
higher R factor indicates a better insulating performance. (t or f)
t
26
The fraction of solar heat that is transmitted through the glazing and ultimately becomes heat.
Solar Heat Gain Coefficient (SHGC)
27
The higher the SHGC, the less solar heat is transmitted through the glazing and the greater it’s shading ability. (t or f)
f( lower the shgc)
28
East- and west-facing windows that receive undesirable direct sunlight in mornings and afternoons should have lower SHGC assemblies.(t iorf)
t
29
Is the percentage of visible light (light in the 380 to 720 nm range) that is transmitted through the glazing.
Visible Transmittance (VT)
30
Is the ratio between SHGC and VT of a single glazing
Light-to-solar Gain Ratio (LSG)
31
Historically, only _____ was used as a glazing material.
glass
32
must be designed to provide illumination in areas where it is most needed and to do so without adversely affecting occupant comfort.
Daylighting systems
33
is to increase the number and size of glazed areas in the walls or ceilings of a building, but simply using large glazed openings does not ensure good daylighting.
Basic daylighting strategy
34
The main functions of_______ are to bring in daylight and fresh air
windows
35
Is a design term that describes window size, arrangement, and glazing type (the glass and coatings used in the window).
Fenestration
36
Is a fenestration arrangement in an upper story wall that extends above one roof surface; it introduces daylight into the ceiling area of the space.
Clerestory Window System
37
An_______ is an interior courtyard covered with glazing. Rooms and spaces 8 adjoining the atrium receive daylight entering through the glazed roof.
atrium
38
A ________ arrangement of several smaller windows can provide uniform daylight illumination if properly distributed in the space being illuminated.
fenestration
39
In hot climates in the northern hemisphere, the low position of the sun produces a shallow angle and a heat gain that contributes to space heating. (t or f)
f(cold climates)
40
Limit solar gains in the summer because the steep angle of the summer sun with respect to the glass.
South-facing windows
41
Exposed to considerable direct sunlight during these times of the day
East-and West – facing windows
42
Windows facing in these directions should only be used when no other method of introducing daylight is possible and where control of direct sunlight and glare is achievable
East-and West – facing windows
43
windows facing in this direction provide good quality daylighting, excessive heat loss and mean radiant temperature in the winter is a concern in cold climates.
North-facing windows
44
Is a transparent panel located in a roof opening that allows direct and diffuse sunlight into the building
Skylights
45
Is a type of skylight system that is a raised, typically triangular shaped, extension of a roof and that has at least one glazed surface.
Roof Monitor
46
Is a passive (non-mechanical) architectural element or mechanism that allows sunlight to enter deep into a building.
Reflective Light Shelves
47
Is a type of light pipe that has a movable mirror or light-refracting system and that can be used to align the incoming sunlight with the axis of the light pipe, thereby minimizing reflection losses
Sun tracking light pipe
48
can be used to introduced daylight through the roof itself
Fabric Roof Membrane
49
use a membrane, supported by a cable, to act as the roof of a structure.
Tension structures
50
Air-supported structures
use a membrane, supported by — air pressure, to act as the roof and walls of the structure.
