Current through Register Vol. 24-14, July 15, 2024
SATURATED-CONDENSING TEMPERATURE.
The saturation
				temperature corresponding to the measured refrigerant pressure at the condenser
				inlet for single component and azeotropic refrigerants, and the arithmetic
				average of the dew point and
bubble point
temperatures
				corresponding to the refrigerant pressure at the condenser entrance for
				zeotropic refrigerants.
SEMI-HEATED SPACE.
An
enclosed space
within a building, including adjacent connected spaces separated by an
				uninsulated component (e.g., basements, utility rooms, garages, corridors),
				which:
1. Is heated but not cooled,
			 and has an installed heating system output capacity greater than or equal to
			 3.4 Btu/(h-ft2) but not greater than 8
			 Btu/(h-ft2);
2. Is not a
walk-in cooler
,
walk-in freezer
,
refrigerated warehouse
			 cooler
or
refrigerated warehouse freezer
space.
SENSIBLE RECOVERY EFFECTIVENESS.
Change in the
				dry-bulb temperature of the outdoor air supply divided by the difference
				between the outdoor air and return air dry-bulb temperatures, expressed as a
				percentage, governed by AHRI Standard 1060.
SERVICE WATER HEATING.
Heating water for domestic
				or commercial purposes other than space heating and process
				requirements.
SIDELIT.
See Section C405.2.5.2.
SINGLE-PASS HEAT PUMP WATER HEATER.
A heat pump
				water heater control strategy using variable flow or variable capacity to
				deliver water from the heat pump at the final target storage water temperature
				in a single-pass through the heat exchanger with variable incoming water
				temperatures.
SINGLE-RAFTER ROOF.
A roof where the roof above
				and the ceiling below are both attached to the same wood rafter and where
				insulation is located in the space between these wood rafters.
SKYLIGHT.
See "Fenestration."
SLAB BELOW GRADE.
Any portion of a slab floor in
				contact with the ground which is more than 24 inches below the final elevation
				of the nearest exterior grade.
SLAB-ON-GRADE FLOOR.
That portion of a slab floor
				of the building envelope that is in contact with the ground and that is either
				above grade or is less than or equal to 24 inches below the final elevation of
				the nearest exterior grade.
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
.
SMALL ELECTRIC MOTOR.
A general purpose,
				alternating current, single speed induction motor.
SMALL BUSINESS.
Any business entity (including a
				sole proprietorship, corporation, partnership or other legal entity) which is
				owned and operated independently from all other businesses, which has the
				purpose of making a profit, and which has fifty or fewer employees.
SOLAR HEAT GAIN COEFFICIENT (SHGC).
The ratio of
				the solar heat gain entering the space through the fenestration assembly to 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.
SOLAR ZONE.
A clear area or areas reserved solely
				for current and future installation of photovoltaic or solar hot water
				systems.
SPACE CONDITIONING CATEGORY.
Categories are based
				on the allowed peak space conditioning output capacity per square foot of
				conditioned floor area, or the design set point temperature, for a building or
				space. Space conditioning categories include: Low energy, semi-heated,
				conditioned, refrigerated walk-in and warehouse coolers, and refrigerated
				walk-in and warehouse freezers.
STAND-ALONE DEHUMIDIFIER.
A product with the sole
				purpose of dehumidifying the space that does not include a portable air
				conditioner, room air conditioner, or packaged terminal air conditioner.
				Stand-alone dehumidifier is a self-contained, electrically operated, and
				mechanically encased assembly consisting of:
1. A refrigerated surface (evaporator) that
			 condenses moisture from the atmosphere;
2. A refrigerating system, including an
			 electric motor;
3. An
			 air-circulating fan; and
4. A means
			 for collecting or disposing of the condensate.
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 and
				carbon emissions from energy consumption for compliance based on total building
				performance and
HVAC total system performance ratio
.
STEEL-FRAMED WALL.
A
wall
with a
				cavity (insulated or otherwise) whose exterior surfaces are separated by steel
				framing members (i.e., typical steel stud
walls
and curtain
wall systems
).
STOREFRONT.
A system of doors and windows mulled
				as a composite fenestration structure that has been designed to resist heavy
				use.
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, with or without mulled
				windows and doors.
SUBSYSTEM METER.
A meter placed downstream of the
				energy supply meter that measures the energy delivered to a load or a group of
				loads.
SYSTEM.
A combination of equipment and auxiliary
				devices (e.g., controls, accessories, interconnecting means and terminal
				elements) by which energy is transformed so it performs a specific function,
				such as HVAC,
service water heating
or
				lighting.
