						  delivered to the building or separately metered portion of the building.
2. Solid fuels such as coal, firewood or wood pellets
						  that are delivered via mobile transportation do not require metering.

			 display in a location with
ready access
, or a single web page
			 or other electronic document available for access to building operation and
			 management personnel or to a third-party energy data analysis service shall be
			 provided in the building; for metering data acquisition systems and energy
			 displays monitored by a third-party energy data analysis service, building
			 operation and management personnel shall retain access to the metering data
			 acquisition system and energy display. The display shall numerically provide
			 the current energy consumption rate and energy consumption total for each whole
			 building energy source and each end use category. The energy display shall also
			 graphically and numerically display logged data from the data acquisition
			 system for energy consumption for each whole building energy source and energy
			 consumption rate for whole building electrical use and each end use category
			 for any selected day, week, month, or year.

A103.1 General.
The tables in this section list
				heat loss coefficients for the opaque portion of above-grade wood stud frame
				walls, metal stud frame walls and concrete masonry walls (Btu/h "
				ft2 " °F). They are derived from procedures
				listed in the ASHRAE Fundamentals Handbook. For intermediate floor slabs which
				penetrate the insulated wall, use the concrete wall U-factors in Table
				A103.3.7.1(1).
Insulation is assumed to uniformly fill the entire cavity and
				to be installed as per manufacturer's directions. All walls are assumed to be
				finished on the inside with 1/2 inch gypsum wallboard, and on the outside with
				either beveled wood siding over 1/2 inch plywood sheathing or with 5/8 inch
				T1-11 siding. Insulated sheathing (either interior or exterior) is assumed to
				cover the entire opaque wall surface, except where modified in accordance with
				footnote g to Table C402.1.3.
Metal building walls have a different construction and are
				addressed in Table A103.3.6.3.

A103.2 Framing description.
For wood stud frame
				walls, three framing types are considered and defined as follows:
A103.2.1 Standard.
Studs framed on 16 inch centers
				with double top plate and single bottom plate. Corners use three studs and each
				opening is framed using two studs. Headers consist of double 2x or single 4x
				material with an air space left between the header and the exterior sheathing.
				Interior partition wall/exterior wall intersections use two studs in the
				exterior wall.
Standard framing weighting factors:
Studs and plates
0.19
Insulated cavity
0.77
Headers
0.04
A103.2.2 Intermediate.
Studs framed on 16 inch
				centers with double top plate and single bottom plate. Corners use two studs or
				other means of fully insulating corners, and each opening is framed by two
				studs. Headers consist of double 2x material with R-10 insulation. Interior
				partition wall/exterior wall intersections are fully insulated in the exterior
				wall.
Intermediate framing weighting factors:
Studs and plates
0.18
Insulated cavity
0.78
Headers
0.04
A103.2.3 Advanced.
Studs framed on 24 inch centers
				with double top plate and single bottom plate. Corners use two studs or other
				means of fully insulating corners, and one stud is used to support each header.
				Headers consist of double 2x material with R-10 insulation. Interior partition
				wall/exterior wall intersections are fully insulated in the exterior
				wall.

				walls are assumed to be 8 inch concrete. The wall is assumed to extend from the
				slab upward to the top of the mud sill for the distance specified in Table
				A104.1, with 6 inches of concrete wall extending above grade.
Interior insulation is assumed to be fiberglass batts placed in
				the cavity formed by 2 x 4 framing on 24 inch centers with 1/2 inch gypsum
				board as the interior finish material. Exterior insulation is assumed to be
				applied directly to the exterior of the below-grade wall from the top of the
				wall to the footing. The exterior case does not assume any interior framing or
				sheetrock.
In all cases, the entire wall surface is assumed to be
				insulated to the indicated nominal level with the appropriate framing and
				insulation application. Coefficients are listed for wall depths of 2, 3-1/2 and
				7 feet below grade. Basements shallower than two feet should use on-grade slab
				coefficients.
Heat-loss calculations for wall areas above-grade should use
				above-grade wall U-factors, beginning at the mudsill.

Tables A105.1(l), A105.1(2) and
				A105.1(3) list heat loss coefficients for floors over unconditioned spaces in
				units of Btu/h * ft2* °F.
They are derived from procedures listed in the ASHRAE
				Fundamentals Handbook, assuming an average outdoor temperature of 45°F, an
				average indoor temperature of 65°F and a crawlspace area of 1350
				ft2 and 100 feet of perimeter. The crawlspace is
				assumed to be 2.5 feet high, with 24 inches below grade and 6 inches above
				grade.

A105.2 Crawlspace description.
Four configurations
				are considered: Naturally ventilated crawlspace, mechanically vented
				crawlspace, heated plenum crawlspace and exposed floor.
A105.2.1 Naturally ventilated crawlspaces.
Assumed
				to have 3.0 air changes per hour, with at least 1.0
				ft2 of net-free ventilation in the foundation for
				every 300 ft2 of crawlspace floor area. The
				crawlspace is not actively heated. Floors over unheated areas, such as garages,
				may only use those values which have R-0 perimeter insulation.
A105.2.2 Mechanically ventilated crawlspaces.
Assume to have 1.5 air changes per hour, with less than 1.0
				ft2 of net-free ventilation in the foundation for
				every 300 ft2 of crawlspace floor area. The
				crawlspace is not actively heated. Floors over unheated basements may only use
				those values which have R-0 perimeter insulation.
A105.2.3 Heated plenum crawlspaces.
Assumed to
				have 0.25 air changes per hour, with no foundation vents. Heated supply air
				from central furnace is blown into a crawlspace and allowed to enter the living
				space unducted via holes cut into the floor.
A105.2.4 Exposed floors.
Assumes no buffer space,
				and a covering of 1/2 inch T1-11 on the exterior of the cavity exposed to the
				outside air or rigid insulation below a concrete floor, such as over parking
				garages.

A105.3 Construction description.
Floors are
				assumed to be either joisted floors framed on 16 inch centers, or post and beam
				on 4 foot by 8 foot squares. Insulation is assumed to be installed under the
				subflooring between the joists or beams with no space between the insulation
				and the subfloor. Insulation is assumed to be uncompressed. Exposed floors also
				include concrete with continuous rigid insulation assumed.
Perimeter insulation is assumed to extend from the top of the
				rim joist to the crawlspace floor and then inward along the ground (on top of
				the ground cover) for at least 24 inches.
Floor coverings are assumed to be light carpet with rubber
				pad.
