Current through Register Vol. 46, No. 28, July 10, 2024
(a)
Definitions.
The
				following words and phrases as used in this Part shall have the following
				meanings, unless a different meaning is plainly required by the context:
(1)
Building.
A combination
				of any materials, whether portable or fixed, forming a structure in which
				energy usage takes place in the normal course, affording shelter for persons or
				property.
(2)
Dwelling.
A building other than a mobile home, designed or
				used as a living unit for one or more families.
(3)
Living unit.
A dwelling
				or portion thereof, providing complete living facilities for one family,
				including permanent provision for living, sleeping, eating, cooking and
				sanitation.
(4)
Commercial
				building.
Any building that cannot be classified as a dwelling or
				mobile home.
(5)
Insulation.
Any material which has a relatively high
				resistance to heat flow, and which is used principally to retard the flow of
				heat.
(6)
Btuh.
British thermal units per hour.
(7)
Heat transmission.
The amount of heat, measured in Btuh,
				transferred from one location to another location as a result of the
				temperature difference in the two locations.
(8)
Coefficient of heat
				transmission.
The amount of heat transfer through a material or
				arrangement of material expressed in Btuh per square foot per degree Fahrenheit
				temperature difference. For outside surfaces, the wind velocity is 15 miles per
				hour. The coefficient of heat transmission is represented by the symbol "U".
				For wood frame construction, the effect of normal framing members may be
				neglected in the determination of U values.
(9)
Basement.
A space of
				full-story height below the first floor of a building which is not designed or
				used primarily for living accommodations.
(10)
Unheated basement.
A
				basement in a dwelling which is not provided with a heat source sufficient to
				maintain a minimum temperature of 50°F.
(11)
Crawl space.
Any
				unfinished, accessible space below the first floor which is less than
				full-story height.
(12)
Unheated crawl space.
A crawl space in a one- or two-family
				dwelling or multifamily dwelling which is not provided with a heat source
				sufficient to maintain a minimum temperature of 50°F.
(13)
Heated space.
Any space
				within the building which is provided with a heat source sufficient to meet the
				design dry bulb temperature, but which is neither a heated basement nor heated
				crawl space as determined by application of the definitions in this
				section.
(14)
Mobile
				home.
This means a structure, transportable in one or more sections,
				which is 8 body feet or more in width and is 32 body feet or more in length,
				and which is built on a permanent chassis, and designed to be used as a
				dwelling, with or without permanent foundation, when connected to the required
				utilities, and includes the plumbing, heating, air-conditioning and electrical
				systems contained therein.
(15)
Utility.
A municipal electric or rural electric cooperative
				system which receives its full power requirements from the Power
				Authority.
(16)
Power
				Authority.
The Power Authority of the State of New York.
(17)
Combined thermal
				transmittance.
An overall coefficient of heat gain expressed in units
				or Btuh per square foot as calculated using Equation 1.
(18)
System.
A combination
				of central or terminal equipment or components and/or controls, accessories,
				interconnecting means, and terminal devices by which energy is transformed so
				as to perform a specific function, such as HVAC, service water heating or
				illumination.
(19)
Automatic.
Self-acting, operating by an internal mechanism
				when actuated by some impersonal influence, as for example, a change in current
				strength, pressure, temperature or mechanical configuration.
(20)
Automatic setback
				thermostat.
An automatic control device actuated by temperature and
				designed to be responsive to temperature capable of automatically reducing its
				set-point temperature during a predesignated period.
(21)
Setback controller.
An
				automatic control device capable of reducing the set-point temperature of
				several thermostats during a predesignated period.
(22)
Hydronic heating
				system.
A heating system using primarily liquid or gaseous water to
				distribute heating energy throughout the building.
(23)
Zone.
A space or group
				of spaces within a building with heating and/or cooling requirements
				sufficiently similar so that comfort conditions can be maintained throughout by
				a single controlling device.
(24)
Thermostatic control valve.
An automatic control valve
				designed to be responsive to room air temperature.
(25)
Energy audit.
An
				engineering analysis which shall consider all possible energy conservation
				measures and shall identify the estimated costs and energy cost savings likely
				to be realized from their implementation.
