PPD - ARE 5.0 (NCARB)Analemma - 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 - answer The outdoor temperature at which a building
makes the transition from a heating to a cooling need
Daylight autonomy - answer 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 - answer The ratio expressed as a percentage othe indoor aluminates at
a point on a horizontal surface to the unobstructed Exterior horizontal illuminance
Effective aperture - answer The product of visible transmittance and the window to wall
ratio
Equation of time - answer 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 - answerA 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 - answerVisible light from the sun and sky, reflected by exterior surfaces
below the plane of the horizon
Light shelf - answerA horizontal element position above eye level and designed to
reflect daylight on the ceiling for improved daylighting effectiveness

regardless of which way electricity flows as a part of the utility Grid.
Radiation spectrum - answerThe 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 - answerPassive 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 - answerThe 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 - answerThe 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 - answerThe ratio of the solar heat gain thru a fenestration to
the total solar radiation incident on the glazing.
Solar time - answerThe 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 - answerThe 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 - answerThe fraction of visible light that passes through a
glazing material
Window to wall ratio - answerThe ratio of the net glazing area in your room or space to
the gross exterior wall area
Work plane - answerThis assumed height at which work is performed usually
considered to be at a desk height, 30 inches above the floor
Co product - answerA marketable byproduct from a process. Materials traditionally
considered to be waist but they can be repurposed as raw materials and a different
manufacturing process.
Demand control ventilation - answerA system designed to adjust the amount of
ventilation air provided to a space based on the extent of occupancy. The system
normally uses some type of sensors
Detention - answerThe 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 - answerThe 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 - answerThe total energy required to extract produce fabricate and
deliver material to a job site including the collection of raw materials, the energy used to

soil based on their potential for a run off with the really wet.
Infiltration - answerThe process of percolating stormwater into the subsoil
Post consumer - answerReferring to a material or product that has served its intended
use it has been diverted recovered from Waze destined for disposal, having completed
its life as a consumer item
Postindustrial - answerReferring to materials generated in manufacturing processes,
such as trimmings or scrap, that have been recovered from solid waste
Recovered materials - answerWaste or buy products that have been recovered from
solid waste disposal. This term does not apply to materials that are generated or reused
within an original manufacturing process
