ARE 5.0 PROJECT PLANNING &
DESIGN (ARCHITECTURE
EXAMINATION) EXAM 2025
QUESTIONS AND ANSWERS
annalemma - ....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 aperature - ....ANSWER ...-The product of visible transmittance and the
window to wall ratio
....FOR STUDY PURPOSES...©️2025 ALL RIGHTS RESERVED... 1
,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 - ....ANSWER ...-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 - ....ANSWER ...-Visible light from the sun and sky, reflected by
exterior surfaces below the plane of the horizon
Light shelf - ....ANSWER ...-A horizontal element position above eye level and
designed to reflect daylight on the ceiling for improved daylighting effectiveness
Net metering - ....ANSWER ...-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 - ....ANSWER ...-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 - ....ANSWER ...-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 - ....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 - ....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 - ....ANSWER ...-The ratio of the solar heat gain thru a
fenestration to the total solar radiation incident on the glazing.
Solar time - ....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 - ....ANSWER ...-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 - ....ANSWER ...-The fraction of visible light that
passes through a glazing material
Window to wall ratio - ....ANSWER ...-The ratio of the net glazing area in your
room or space to the gross exterior wall area
Work plane - ....ANSWER ...-This assumed height at which work is performed
usually considered to be at a desk height, 30 inches above the floor
Co product - ....ANSWER ...-A marketable byproduct from a process. Materials
traditionally considered to be waist but they can be repurposed as raw materials and a
different manufacturing process.
