or material meets nationally recognized standards or has been tested and found suitable for use in a specified manner. LOW-VOLTAGE LIGHTING. Lighting equipment powered through a transformer such as a cable conductor, a rail conductor and track lighting. MANUAL. Capable of being operated by personal intervention (see "Automatic"). PROPOSED DESIGN. A description of the proposed building used to estimate annual energy use for determining compliance based on total building performance. , READILY ACCESSIBLE. Capable of being reached quickly for operation, renewal or inspection without requiring those to whom ready access is requisite to climb over or remove obstacles or to resort to portable ]adders or access equipment (see "Accessible"). REPAIR. The reconstruction or renewal of any part of an existing building. RESIDENTIAL BUILDING. For [his code, includes R-3 buildings, as well as R-2 and R-4 buildings three stories or less in height above grade. R -VALUE (THERMAL RESISTANCE). The inverse of the time rate of heat flow through a body from one of its bounding surfaces to the other surface for a unit temperature difference between the two surfaces, under steady state conditions, per unit area (h x ft 2 x ° FBtu) [(m~ x K)/W]. ROOF ASSEMBLY. A system designed to provide weather protection and resistance to design loads. The system consists of a roof covering and roof deck or a single component serving as both the roof covering and the roof deck. A roof assembly includes the roof covering, underlayment, roof deck, insulation, vapor retarder and interior finish. SCREW LAMP HOLDERS. A lamp base that requires ascrew-in-type lamp, such as a compact-fluorescent, incandescent, or tungsten-halogen bulb. SERVICE WATER HEATING. Supply of hot water for purposes other than comfort heating. SKYLIGHT. Glass or other transparent or translucent glazing material installed at a slope of 15 degrees (0.26 red) or more from vertical. Glazing material in skylights, including unit skylights, solaziums, sunrooms, roofs and sloped walls is included in this definition. SLEEPING UNIT, A room or space in which people sleep, which can also include permanent provisions for living, eating, and either sanitation or kitchen facilities but not both. Such rooms and spaces that are also part of a dwelling unit are not sleeping units. SOLAR HEAT GAIN COEFFICIENT (SHGC). The ratio of the solar heat gain entering the space through the fenestration assembly [o the incident solar radiation. Solar heat gain includes directly transmitted solar heat and absorbed solar radiation which is then reradiated, conducted or convected into the space. STANDARD REFERENCE DESIGN. A version of the proposed design that meets the minimum requirements of this code and is used to determine the maximum annual energy use requirement for compliance based on total building performance. STOREFRONT. A nonresidential system of doors and windows mulled as a composite fenestration structure that has been designed to resist heavy use and possible abuse and provide a high level of resistance to wind load and impact from wind borne debris. Storefront systems include, but are not limited to, exterior fenestration systems that span from the floor level or above to the ceiling of the same story on commercial buildings. SUNROOM. A one-story structure attached to a dwelling with a glazing area in excess of 40 percent of the gross area of the structure's exterior walls and roof. THERMAL ISOLATION. Physical and space conditioning separation from conditioned space(s). The conditioned space(s) shall be controlled as separate zones For heating and cooling or conditioned by separate equipment. THERMOSTAT. An automatic control device used to maintain temperature at a fixed or adjustable set point. U -FACTOR (THERMAL TRANSMITTANCE). The coefficient of heat transmission (air to air) through a building component or assembly, equal to the time rate of heat flow per unit area and unit temperature difference between the warm side and cold side air films (Btu/h ~ ft 2 ° F) VAPOR RETARDER. A vapor resistant material, membrane or covering such as foil, plastic sheeting, or insulation facing having a permeance rating of 1 perm (5.7 x 10 -1 I kg/Pa • s mz) or less-when tested in accordance with the dessicant method using Procedure A of ASTM E 96.
