Spaces that are temporarily enclosed such as patios enclosed with tenting are not considered Enclosed Spaces for annual building analysis. These spaces should be treated as exterior to the building. [cu.ft.] Volume inside the building envelope of the conditioned spaces. This metric can be calculated as the volume of the building if every space is conditioned or on a floor-by-floor basis. For spaces with vertical walls and horizontal ceilings and floors, this is calculated as the Gross Conditioned Floor Area times the height from the top surface of the finished floor to the top surface of the finished floor separating levels of the building or to the inside surface of the roof for the top floor. The volume of spaces that have nonvertical walls or nonhorizontal ceilings of floors should be calculated separately to properly account for the non-rectangular geometry. This metric does include the volume of floor or ceiling return air plenums. Primary foundation type of building Primary attic type of building The number of sections (width) of the manufactured home. CrossMod is a new style of manufactured home with more flexibility in configuration, higher roof pitch, covered porches, and garages or carports. They look more like a site-built single family detached home, but are manufactured in a factory and assembled on site. Weather location used in model simulation and/or utility bill regression analysis A listing of Green Building Verifications from the RESO Data Dictionary The name of the verification or certification awarded to a new or pre-existing residential or commercial structure. For example: LEED, Energy Star, ICC-700. In cases where more than one certification have been awarded, leverage multiple iterations of the green verification fields via the repeating element method. If "other" is selected for GreenBuildingVerification/Type, fill in type here. The name of the body or group providing the verification/certification/rating named in the GreenBuildingVerificationType field. There is almost always a direct correlation between bodies and programs. A final score indicating the performance of energy efficiency design and measures in the home as tested by a third-party rater. Points achieved to earn a certification in the GreenVerificationRating field do not apply to this field. HERS Index is most common with new homes and runs with a lower number being more efficient. A net-zero home uses zero energy and has a HERS score of 0. A home that produces more energy than it uses has a negative score. Home Energy Score is a tool more common for existing homes and runs with a higher number being more efficient. It takes square footage into account and caps with 10 as the highest number of points. Many verifications or certifications have a rating system that provides an indication of the structure's level of energy efficiency. When expressed in a numeric value, please use the GreenVerificationMetric field. Verifications and Certifications can also be a name, such as Gold or Silver, which is the purpose of this field. The source of the green data. May address photovoltaic characteristics, or a verified score, certification, label, etc. This may be a pick list of options showing the source. i.e. Program Sponsor, Program Verifier, Public Record, Assessor, etc. Many verification programs include a multi-step process that may begin with plans and specs, involve testing and/or submission of building specifications along the way and include a final verification step. When ratings are involved it is not uncommon for the final rating to be either higher or lower than the target preliminary rating. Sometimes the final approval is not available until after sale and occupancy. Status indicates what the target was at the time of listing and may be updated when verification is complete. To limit liability concerns this field reflects information that was available at the time of listing or updated later and should be confirmed by the buyer. Provides a link to the specific property’s high-performance rating or scoring details directly from and hosted by the sponsoring body of the program. Typically provides thorough details, for example, which points where achieved and how, or in the case of a score what specifically was tested and the results. The version of the certification or verification that was awarded. Some rating programs have a year, a version, or possibly both. The year the certification or verification was awarded.

EUI represents the energy consumed by a building relative to its size. Period during which electrical power is expected to be provided at a significantly higher than average supply level. Water use intensity is defined as annual water use divided by total gross square footage of facility space reported in gallons per square foot (DOE, 2013). This element may also be reported as gallons, per day, per person.

[deg F] This element is intended to describe the type of infiltration measured, e.g., for an individual single-family attached or multifamily dwelling unit. Either whole building or single unit infiltration can be measured. For single unit infiltration, leakage can occur through exterior surfaces, interior surfaces, or both. For example, guarded tests measure unit exterior leakage, unguarded or compartmentalization tests measure unit total leakage, and combining both tests can measure unit interior leakage. [Pa] with respect to outside [Pa] [sq.in.] The Effective Leakage Area is defined as the area of a special nozzle-shaped hole (similar to the inlet of a blower door fan) that would leak the same amount of air as the building does at a pressure of 4 Pascals.

The floor is supported on a pair of I-beams spanning across the length of the manufactured home. The floor wing is the part of the floor outside the supports, and the floor belly is the part between the supports. The floor wing and belly sections are protected from outside elements including water, wind, and rodents using a wrap attached to the underside of floor joists, and may contain insulation. Use the 'none' choice for cases where the belly wrap is functionally missing even if pieces of the wrap are still present. Sheathing insulation should be specified in the Insulation element as well. Please specify stud spacing and framing factor in the appropriate places as well. See https://thecraftsmanblog.com/framing-timber-balloon-platform for a description of different framing types.
