Annalemma - CORRECT ANSWER-The figure 8 curve that
represents the angular offset of the sun from its mean position
at as viewed from the earth
Balance Point Temperature - CORRECT ANSWER-The
outdoor temperature at which a building makes the transition
from a heating to a cooling need

account for the difference between solar time and clock time.
,Solar time is based on the position of the sun. It's basic unit is
the solar day
Glazing factor - CORRECT ANSWER-A LEED based number

Shading coefficient - CORRECT ANSWER-The ratio of the
solar heat gain thru a glazing product to the solar heat gain
through an untreated 1/8 in clear double strength glass under
the same set of conditions. This is the value for the glass only,
does not include the frame
,Solar constant - CORRECT ANSWER-The amount of solar
energy that falls in our unit time on her unit area that is
93,000,000 miles from the sun and orientated on a plane
perpendicular to the suns rays. The mean value of the solar
constant is 433 btu/hr-ft
Solar heat gain coefficient - CORRECT ANSWER-The ratio of
the solar heat gain thru a fenestration to the total solar radiation
incident on the glazing.
Solar time - CORRECT ANSWER-The time as defined by the
sun and it's position relative to the earth. Because the length of
the solar day varies most reference the mean solar day as a
basis for timekeeping.
Solar savings fraction - CORRECT ANSWER-The fraction of

transportation from the original site to the processing plant, that
energy required to turn the wrong materials into a finish
product, and energy required to transport the material to the job
site
Fee in Lieu - CORRECT ANSWER-Payment of money by
developer in place of meeting all or part of stormwater
performance standards

for run off potential A classification of soil based on their
potential for a run off with the really wet.
Infiltration - CORRECT ANSWER-The process of percolating
stormwater into the subsoil
Post consumer - CORRECT ANSWER-Referring to a material
or product that has served its intended use it has been diverted
