Questions with 100% Correct Answers
Annalemma - ✔✔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 - ✔✔The outdoor temperature at which a building
makes the transition from a heating to a cooling need
Daylight autonomy - ✔✔The percentage of an area that meets a minimum
daylight illuminance level or specified fraction of the operating hours per year.
also referred to as special daylight autonomy
Daylight factor - ✔✔The ratio expressed as a percentage othe indoor aluminates
at a point on a horizontal surface to the unobstructed Exterior horizontal
illuminance
Effective aperature - ✔✔The product of visible transmittance and the window
to wall ratio
Equation of time - ✔✔The factor used to 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 - ✔✔A LEED based number calculated by taking into account
window area, floor area, a window geometry factor, light transmission, and a
window height factor.
Ground light - ✔✔Visible light from the sun and sky, reflected by exterior
surfaces below the plane of the horizon
Light shelf - ✔✔A horizontal element position above eye level and designed to
reflect daylight on the ceiling for improved daylighting effectiveness
Net metering - ✔✔The requirement that a utility pay and charge equal rates
regardless of which way electricity flows as a part of the utility Grid.
Radiation spectrum - ✔✔The entire range of electromagnetic radiation
extending from 0 hz to 1023 hz. This includes visible light as well as infrared
radiation, radio waves, and gamma rays among others
Radiative cooling - ✔✔Passive or active design strategy that uses thermal mass
to collect and store heat during the day for release at night. Also known as
nocturnal cooling and night cooled mass
Shading coefficient - ✔✔The ratio of the solar heat gain thru a glazing product

,under the same set of conditions. This is the value for the glass only, does not
include the frame
Solar constant - ✔✔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 - ✔✔The ratio of the solar heat gain thru a
fenestration to the total solar radiation incident on the glazing.
Solar time - ✔✔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 - ✔✔The fraction of the total energy used by system that
is provided by solar technology. Represented by the variable F, it is a decimal
fraction from 0 to 1
Visible light transmittance - ✔✔The fraction of visible light that passes through
a glazing material
Window to wall ratio - ✔✔The ratio of the net glazing area in your room or
space to the gross exterior wall area

ventilation air provided to a space based on the extent of occupancy. The
system normally uses some type of sensors
Detention - ✔✔The temporary storage of storm run off and the detention
facility to control Pete's discharge rates and provides gravity settling of
pollutants. Provides a gradual release of stored water at a controlled rate
Drainage easement - ✔✔The legal rights granted by a land owner to a grantee,
commonly a governmental entity, allowing the use of private land for
Stormwater management
Embodied energy - ✔✔The total energy required to extract produce fabricate
and deliver material to a job site including the collection of raw materials, the
energy used to achieve extract and process the wrong materials, transportation
from the original site to the processing plant, that energy required to turn the
