Utah Admin. Code R362-2-3 - Definitions
The definitions below are in addition to or serve to clarify the definitions in Sections 59-7-614, 59-10-1014, and 59-10-1106.
(1) "Active solar thermal systems" include
systems that can do one of the following:
(a)
heat water for space heating, culinary water, recreational use including
swimming pools and other industrial or commercial uses;
(b) heat a liquid, contained within a closed
loop system, whose transferred heat may be used for space heating, culinary
water, recreational use (including swimming pools), and other industrial or
commercial uses; or
(c) heat air
that is transferred to a building's conditioned space using mechanical systems
such as fans or blowers either for heat or to induce air movement used for
cooling;
(d) active solar thermal
systems do not include systems that use heat for evaporative cooling.
(2) "Biomass system" means a
system of apparatus and equipment for use in converting biomass material into
fuel or electricity and transporting that energy by separate apparatus to the
point of use or storage.
(a) A biomass system
does not include biomass from municipal solid waste other than methane produced
at landfills or sewage treatment plants.
(b) To be considered a biomass system, a fuel
or electricity producing system must use biomass as its primary source of
energy.
(3) "Commercial
energy system" means any renewable energy system used to supply energy to a
commercial unit or as a commercial enterprise. In the case of systems
generating electricity and involving multiple but interconnected energy
generation systems, a commercial energy system includes interconnected
components that:
(a) were assembled or
constructed at approximately the same time as part of a single project;
and
(b) supply electricity to a
common grid interconnection point.
(4) "Commercial unit" means any building or
structure that a business entity uses to transact its business. For purposes of
the commercial investment tax credit, an agricultural water pump and a wind
turbine are each considered to be single commercial units.
(5) "Direct use geothermal system" means a
system of apparatus and equipment enabling the direct use of thermal energy,
generally between 100 and 300 degrees Fahrenheit that is contained in the earth
to meet energy needs including heating a building, an industrial process, or
aquaculture. Such systems generally make use of hot water or steam derived from
wells bored through the earth's crust to reach areas of thermal energy. It may
include systems that make use of groundwater or those that inject water into
the earth to derive heat. It can also include systems that pump a heat
exchanging fluid through a sealed, close loop system below the ground to
extract heat for use above the earth's surface.
(6) "Eligible cost" means a cost that is
incurred for the purchase and installation of a renewable energy system, and
that may be used in calculating the amount of either a commercial or
residential investment tax credit.
(7) "Heat transportation system" means all
fans, vents, ducts, pipes and heat exchangers designed to move heat from a
collection point to either the storage or heat use area.
(8) "Placed in commercial service" means the
commercial operations date (COD) when the commercial energy system is no longer
testing functionality of a new commercial energy system and is selling produced
electricity at a non-discounted price.
(9) "Residential unit" means any house,
condominium, apartment, or similar dwelling for a person, but it does not
include any vehicles such as motor homes, recreational vehicles, or house
boats.
(10) "Solar PV energy
system" means an active solar energy system that converts light to direct
current electricity through semiconducting materials and that is capable of
producing electricity for use in a building by the use of an inverter to
produce alternating current electricity. Solar PV energy systems include solar
attic fans.
(11) "Thermal storage
mass" means a structure within the conditioned space consisting of a material
with high thermal capacitance or mass to provide heat to the unit at times of
low or no heat collection.
