Definitions. The following definitions relate to alternative energy systems including geothermal, outdoor hydronic heaters, solar and wind energy systems, and anaerobic digesters.
ANAEROBIC DIGESTERA facility which main purpose is to use anaerobic digestion processes to convert livestock manure (primary catalyst) and feedstock into biogas, which is generally burned on site to produce electricity, heat, and water; as well as to manage livestock and poultry manure. Anaerobic digesters may include "co-digestion" in which the livestock and poultry manure (primary catalyst) may be mixed with other organic materials (secondary catalysts). Types of anaerobic digesters include covered anaerobic lagoons, plug-flow, and/or complete mix (or continually stirred tank reactor), along with other appurtenant sites, structures and buildings, electrical infrastructure, transmission lines and other appurtenant structures and facilities.
ANAEROBIC DIGESTIONThe process in which microorganisms in the absence of oxygen convert the energy stored in volatile acids in livestock and poultry manure or other organic materials into biogas.
APPURTENANCESThe visible, functional, or ornamental objects accessory to and part of buildings.
BIOGASA fuel consisting of methane, carbon dioxide, and small amounts of water and other compounds produced as part of anaerobic digestion processes.
GEOTHERMAL TERMS(a) CLOSED HORIZONTAL LOOP GEOTHERMAL SYSTEMA mechanism for heat exchange which consists of the following basic elements: underground loops of piping; heat transfer fluid; a heat pump; an air distribution system. An opening is made in the Earth. A series of pipes are installed into the opening and connected to a heat exchange system in the building. The pipes form a closed loop and are filled with a heat transfer fluid. The fluid is circulated through the piping from the opening into the heat exchanger and back. The system functions in the same manner as the open loop system except there is no pumping of groundwater. A horizontal closed loop system shall be no more than 20 feet deep.
(b) CLOSED VERTICAL LOOP GEOTHERMAL SYSTEMA borehole that extends beneath the surface. Pipes are installed with U-bends at the bottom of the borehole. The pipes are connected to the heat exchanger and heat transfer fluid is circulated through the pipes.
(c) GEOTHERMAL BOREHOLESA hole drilled or bored into the earth into which piping is inserted for use in a closed vertical loop geothermal system.
(d) GEOTHERMAL ENERGY SYSTEMAn energy generating system that uses the Earth's thermal properties in conjunction with electricity to provide greater efficiency in the heating and cooling of buildings.
(e) OPEN HORIZONTAL LOOP GEOTHERMAL SYSTEMWater is pumped from a water well or other water source into a heat exchanger located in a surface building. The water drawn from the Earth is then pumped back into the ground through a different well or in some cases the same well, also known as "re-injection." Alternatively, the groundwater could be discharged to a watercourse also known as a "pump and dump." In the heating mode, cooler water is returned to the earth, and in the cooling mode, warmer water is returned to the watercourse or well.
OUTDOOR HYDRONIC HEATER (WOOD-FIRED BOILER)A fuel-burning device, also known as "outdoor wood-fired furnace," and "outdoor wood-burning appliance," designed:
(a) To burn clean wood or other fuels specifically tested and listed for use by the manufacturer including, but not limited to, clean wood, wood pellets made from clean wood, and other fuel approved in writing by DEP;
(b) By the manufacturer specifically for outdoor installation or installation in structures not normally intended for habitation by humans or domestic animals (e.g., garages); and
(c) To heat building space and/or water via distribution, typically through pipes, of a fluid heated in the device, typically water or a water/antifreeze mixture.
SOLAR ENERGY SYSTEMAny solar collector consisting of one or more cell(s), panel(s), or array(s) designed to collect and convert solar power into another form of energy such as electricity or heat, and other structures and buildings, used in the conversion, storage, and distribution including electrical infrastructure, transmission lines, and other appurtenant structures and facilities.
STACKAny vertical structure enclosing a flue(s) that carry off smoke or exhaust from a furnace or other fuel-burning device, especially that part of a structure extending above a roof.
TURBINE HEIGHTThe distance measured from the highest point of the wind turbine rotor plane to the ground level.
WIND ENERGY SYSTEMA device such as a wind turbine and/or other electric generation facility designed to convert wind power into another form of energy such as electricity or heat, consisting of one or more wind turbines and other structures and buildings, including meteorological towers, electrical infrastructure, transmission lines, and other appurtenant structures and facilities.
WIND TURBINEA device that converts wind energy into electricity through the use of a wind turbine generator, and includes the nacelle, rotor, tower and pad transformer, if any.
