12.
Conditioned
				  space.
"Conditioned space" means an area, room or space that is enclosed
				  within the building thermal envelope and that is directly heated or cooled or
				  that is indirectly heated or cooled. Spaces are indirectly heated or cooled
				  where they communicate thru openings with conditioned spaces, where they are
				  separated from conditioned spaces by uninsulated walls, floors or ceilings or
				  where they contain uninsulated ducts, piping or other sources of heating or
				  cooling.
13.
Draft
				  stop
."Draft stop" means a material, device or construction installed to
				  restrict the movement of air within open spaces of concealed areas of building
				  components such as crawl spaces, floor-ceiling assemblies, roof-ceiling
				  assemblies and attics.
14.
Dwelling unit
."Dwelling unit" means a single unit providing
				  complete independent living facilities for one or more persons, including
				  permanent provisions for living, sleeping, eating, cooking and
				  sanitation.
15.
Exterior
				  door
."Exterior door" means any swinging or sliding door of any size
				  that functions as part of the building thermal envelope.
16.
Fenestration
."Fenestration"
				  means penetrations through the building envelope, including but not limited to
				  skylights, roof windows, vents, ducts, vertical windows (whether fixed or
				  moveable); opaque doors; glazed doors; glass block; and combination of
				  opaque/glazed doors.
17.
Heat
				  loss
."Heat loss" means the amount of heat transferred per unit of time
				  from the conditioned space to the outside or to an unconditioned space by means
				  of conduction and infiltration.
18.
Independence of judgment
."Independence of judgment" means not
				  being affiliated with, or influenced by, or controlled by building
				  manufacturers or by producers, suppliers, or vendors of products or equipment
				  used in manufactured housing, in any manner which is likely to affect the
				  capacity to render reports and findings objectively and without bias.
19.
Infiltration
."Infiltration"
				  means the uncontrolled movement of air into and out of the conditioned space
				  through cracks and interstices in the building envelope.
20.
Installation
."Installation"
				  means the placing of manufactured housing on a foundation or supports at a
				  building site; and the assembly and fastening of structural components of
				  manufactured housing, including the completed roof system, as specified by the
				  manufacturer's installation instructions and in accordance with the rules of
				  the Board.
21.
Journeyman
				  quality workmanship
."Journeyman quality workmanship" means workmanship
				  that equates to the second or intermediate level of development of proficiency
				  in a particular trade or skill, and reflects the work of a skilled worker but
				  without the perfection of a master craftsman.
22.
Label
."Label" means an
				  approved insignia or seal evidencing certification in accordance with the Act
				  and these rules.
23.
Local
				  enforcement agency
. "Local enforcement agency" means the agency or

."Mechanical ventilation" means the controlled, purposeful
				  introduction or removal of air to or from a conditioned space.
25.
REScheck
."REScheck" is
				  computer software published by the U.S. Department of Energy that allows
				  builders to determine a residential structure's overall compliance with a
				  selected energy conservation code by "trading off" insulation levels in the
				  ceiling, wall, floor, basement wall, slab-edge and crawl space; glazing and
				  door areas; glazing and door U-factors; and certain equipment
				  efficiency.
26.
Roof-Ceiling
."Roof-Ceiling" means a roof member that serves also
				  as a ceiling member.
27.
R-value
."R-value," also known as thermal resistance," means the
				  inverse of the time-rate of heat flow through a building envelope element from
				  one of its boundary surfaces to the other for a unit temperature difference
				  between the two surfaces, under steady state conditions, per unit area. R-value
				  is calculated according to the formula (h · ft²
										·
										ºF/Btu). R-value is the reciprocal of the U-factor.
28.
Townhouse
."Townhouse" means
				  a single family dwelling unit constructed in a group of three or more attached
				  units in which each unit extends from foundation to roof and with a yard or
				  public way on at least two sides.

."U-factor, "also
				  known as thermal transmittance, means the coefficient of heat transmission (air
				  to air) through a building envelope component or assembly, equal to the time
				  rate of heat flow per unit area and unit temperature difference between the
				  warm side and the cold side air films. u-factor is calculated according to the
				  formula (Btu/h · ft²
										·
										ºF). U-factor is the reciprocal
				  of the R-value.
30.
Yard
."Yard" means an open space, other than a court, unobstructed
				  from the ground to the sky on the lot which a building is situated.
