UPDATED Exam Questions and
CORRECT Answers
balance point temperature - CORRECT ANSWER - the outdoor temperature at which a
building makes a transition from a heating need to a cooling need
daylight autonomy - CORRECT ANSWER - the percentage of an area that meets a min
daylight illuminance level for a specified fraction of the operating hours per year. LEED credit
daylight factor - CORRECT ANSWER - the ratio expressed as a percentage, of the indoor
illuminance at a point on a horizontal surface to the unobstructed exterior horizontal illuminance.
effective aperture - CORRECT ANSWER - the product of visible transmittance and the
window-to-wall ratio
equation of time - CORRECT ANSWER - factor used to account for the difference
between solar time and clock time. based on sun position
glazing factor - CORRECT ANSWER - LEED based number calculated by taking into
account window area, floor area, a window geometry factor, light transmission and window
height factor.
ground light - CORRECT ANSWER - Visible light from the sun and sky, reflected by
exterior surfaces below the plane of the horizon
net metering - CORRECT ANSWER - the requirement that a utility pay and charge equal
rates regardless of which way electricity flows as part of the utility grid.allows PV's and wind
energy to be sold back
,radiation spectrum - CORRECT ANSWER - the entire range of electromagnetic radiation
extending from 0Hz to 1023 Hz. includes visible light as well as infrared radiation, radio waves,
gamma rays, etc
radiative cooling - CORRECT ANSWER - passive or active design strategy that uses
thermal mass to collect and store heat during the day for release at night. best in climates where
there is significant difference between daytime and night time temperatures such as the
southwest and temperate climates
shading coefficient - CORRECT ANSWER - the ratio of the solar heat gain through a
glazing product to the solar heat gain through an unshaded 1/8" thick, clear, double strength glass
under the same set of conditions.
solar constant - CORRECT ANSWER - the amount of solar energy that falls in a unit time
on a unit area that is 93,000,000 miles from he sun and oriented on a plane perpendicular to the
sun's rays. the mean value is 433 Btu/hr-ft^2
solar heat gain coefficient - CORRECT ANSWER - the ratio of the solar heat gain through
a fenestration to the total solar radiation incident on the glazing. includes directly transmitted
solar heat and absorbed solar radiation. value is between 0 and 1.
solar savings fraction - CORRECT ANSWER - the fraction of the total energy used by a
system that is provided by solar technology.
solar time - CORRECT ANSWER - time as defined by the sun and its position relative to
the earth
visible light transmittance - CORRECT ANSWER - the fraction of visible light that passes
through a glazing material
window -to-wall ratio - CORRECT ANSWER - ratio of the net glazing area in a room or
space to the gross exterior wall area
,stack effect - CORRECT ANSWER - difference in pressure between the top and bottom of
a building due to temperature differential
transparent insulation - CORRECT ANSWER - consists of a relatively thick layer of poly
carbonate honeycomb material, acrylic foam, or fiberglass sandwiched between layers of glazing
closed-loop system - CORRECT ANSWER - antifreeze or some other transfer medium is
heated in the collector and circulated to a heat exchanger, where the domestic water is heated by
the transfer medium
open-loop sysem - CORRECT ANSWER - water is heated directly in the solar collector
flat plate collector - CORRECT ANSWER - consist of network of pipes located on an
absorptive black surface with low emissivity, placed below a covering of glass or plastic
focusing collector - CORRECT ANSWER - parabolic reflectors that focus the incoming
radiation to a single pipe that carries the heat-transfer medium.
thermal storage wall, trombe wall - CORRECT ANSWER - high-mass wall placed directly
behind a south-facing glass wall
shadow mask - CORRECT ANSWER - plot of the shading effects of surrounding
structures and vegetation on a building using solar heating or daylighting
coproduct - CORRECT ANSWER - a marketable by-product from a process.. traditionally
considered to be waste that can be re purposed as raw materials in a different manufacturing
process
demand control ventilation - CORRECT ANSWER - a system designed to adjust the
amount of ventilation air provided to a space based on the extend of occupancy. normally uses
carbon dioxide sensors but also uses occupancy or air quality sensors
, detention - CORRECT ANSWER - temporary storage of storm runoff in a detention
facility to control peak discharge rates and to provide gravity settling of pollutants. gradual
release of stored water
drainage easement - CORRECT ANSWER - the legal right granted by a landowner to a
grantee allowing the use of private land for stormwater management
fee in lieu - CORRECT ANSWER - payment of money by a developer in place of meeting
all or part of stormwater performance standards
hydrologic soil group - CORRECT ANSWER - a classification of soils based on their
potential for runoff when thoroughly wet. group A - contains soils high in gravel and sand that
have high permeability and low runoff potential - group D which contains clayey soils that have
low permeability and high runoff potential
recovered materials - CORRECT ANSWER - waste or by-product that have been
recovered or diverted from solid waste disposal.
fire partition - CORRECT ANSWER - a wall assembly with a 1 hr fire resistance rating
fire barrier - CORRECT ANSWER - a vertical or horizontal assembly that is fire
resistance rated and that is designed to restrict the spread of fire, confine it to limited areas,
and/or afford safe passage for protected egress
fire wall - CORRECT ANSWER - a fire resistance rated wall that is used to separate a
single structure into separate construction types or to provided for allowable area increases by
creating what amounts to separate buildings even thought they are attached
area of refuge - CORRECT ANSWER - an area where people unable to use stairways can
remain temporarily wile waiting for assistance
