Define "U-Factor"

Back 19

the number of BTU per hour that pass through one square foot of wall or roof when the difference between inside and outside air temperature is 1°F, with a steady rate of heat flow. The U value can vary widely, from as low as 0.064 for an insulated brick and plaster wall to over 1.0 for a single pane of ordinary glass. A low U value indicates slow heat loss or gain, while a high U value indicates rapid loss or gain of heat.

Back 20

Thermal Inertia
Heavy materials absorb and store peak heat loads and later release them when the outside temperature drops. In areas with high diurnal (daily) temperature variation, concrete or masonry walls, which have high heat-storage capabilities, are used to store daytime heat and release it during the night, resulting in more balanced conditions. This situation is prevalent in hot, arid zones, such as Phoenix.

Some properties for which soil may be tested include the following:

Back 29

-Specific gravity, to determine void ratio.
-Grain size (for granular soils), to estimate permeability, frost action, compaction, and shear strength.
-Grain shape, to estimate shear strength.
-Liquid and plastic limits (in cohesive soils), to obtain compressibility and compaction values.
-Water content (in cohesive soils), to obtain compressibility and compaction values.
-Void ratio, to determine compressibility.
-Unconfined compression (in cohesive soils), to estimate shear strength.

Sheeting

Front 32

a type of sheeting in which a narrow trench is filled with a slurry, or soupy mixture, of bentonite clay and water, which resists the pressure of the earth.

The site is now excavated, and the reinforced concrete wall is tied back as the excavation progresses to resist the earth pressure is called...
