The heat transfer fluid is potable or beneficial reuse water and may have approved antifreeze added.
COOL ROOFA cool roof is one that has been designed to reflect more sunlight and absorb less heat than a standard roof. Cool roofs can be made of a highly reflective type of paint, a sheet covering, or highly reflective tiles or shingles.
EMERGING ENERGYA source of energy generated from a renewable source, other than solar, water, wind, or geothermal sources, which is capable of providing energy and utility provisions that will be reviewed by the Board of Supervisors.
EMERGING ENERGY FACILITYA private facility capable of converting renewable energy sources into a viable energy source and utility provisions for a permitted use.
FACILITY OWNERThe entity or entities having an interest in the alternative and/or emerging energy facility, including their successors and assigns.
FREESTANDING ALTERNATIVE ENERGY FACILITYA facility that is not physically mounted, attached and/or connected (except utility and energy transfer connections) to a permitted principal building. All such facilities shall be considered a separate or accessory structure that has the ability to convert and convey energy to the principal use in accordance with all pertinent zoning, utility and building code requirements.
GEOTHERMAL SYSTEMA system that uses a heat pump to extract heat from the earth in heating mode and/or reject heat into the earth in cooling mode. It is also called a geothermal heat pump system, a ground-coupled heat pump system, an earth-source heat pump system, and a GeoExchange system.
GREEN ROOFA green roof is a layer of vegetation planted over a waterproofing system that is installed on top of a flat or slightly-sloped roof. Green roofs are also known as vegetative or eco-roofs.
GREEN WALLA green wall is a vertical greening typology, where a vertical built structure is intentionally covered by vegetation. Green walls include a vertically applied growth medium such as soil, substitute substrate, or hydroculture felt, as well as an integrated hydration and fertigation delivery system. Green walls generally fall into one of two categories: soil-less or modular.
1. SOIL-LESSVegetation growing on a vertical structure, mimicking growing conditions found in nature.
2. MODULARPockets of plants and climbing plants and soil media in prefabricated modules to produce a green wall.
GROUND SOURCE HEAT PUMPA geothermal heat pump that uses the earth itself as a heat source and heat sink. It is coupled to the ground by means of a closed-loop heat exchanger installed horizontally or vertically underground.
LANDOWNERAny person(s) or entity owning property within (Municipality).
METEOROLOGICAL TOWERA structure designed to support the gathering of wind energy resource data, and includes the tower, base plate, anchors, guy cables and hardware, anemometers (wind speed indicators), wind direction vanes, booms to hold equipment anemometers and vanes, data logger, instrument wiring, and any telemetry devices that are used to monitor or transmit wind speed and wind flow characteristics over a period of time for either instantaneous wind information or to characterize the wind resource at a given location.
NONPARTICIPATING LANDOWNERAny landowner except those on whose property all or a portion of an alternative and/or emerging energy facility is located pursuant to the provisions of this Part.
OCCUPIED BUILDINGA building located on a parcel of land utilized as a permitted use in accordance with the provisions of Solebury Township.
OPERATORThe entity responsible for the day-to-day operation and maintenance of the alternative and/or emerging energy facility.
PASSIVE HOUSEA passive house is a very well insulated, virtually airtight building that is primarily heated by passive solar gains and internal heat gains, and virtually eliminates the need for heating or cooling.
PHASE 2 OUTDOOR WOOD-FIRED BOILERAn outdoor wood-fired boiler that has been certified or qualified by the EPA as meeting a particulate matter emission limit of 0.32 pounds per million British Thermal Units output and is labeled accordingly. Phase 2 outdoor wood-fired boiler models will be identified with a white hang tag.
PRIVATE ENERGY AND UTILITY PROVIDERA principal use owned, operated and/or maintained by a private or independent utility company for the purposes of providing energy within a defined service area or grid system in accordance with the provisions established by the Public Utility Commission and the Public Utility Code.
SMALL WIND ENERGY SYSTEMA wind energy system consisting of a wind turbine, tower and associated control or conversion electronics, which has a rated power output of 100 kW or less.
SOLAR EASEMENTSLegal agreements that protect access to sunlight on a property.
SOLAR ENERGYRadiant energy (direct, diffused, or reflected) received from the sun at wavelengths suitable for conversion into thermal, mechanical, chemical, or electrical energy.
SOLAR ENERGY SYSTEMAn energy system that consists of one or more solar collection devices, solar energy related "balance of system" equipment, and other associated infrastructure with the primary intention of generating electricity, storing electricity, or otherwise converting solar energy to a different form of energy. Solar energy systems may generate energy in excess of the energy requirements of a property if it is to be sold back to a public utility in accordance with the law.
SOLAR PANELThat part or portion of a solar energy system containing one or more receptive cells or modules, the purpose of which is to convert solar energy for use in space heating or cooling, for water heating and/or for electricity.
SOLAR REFLECTIVE INDEXThe solar reflectance index (SRI) is a measure of the constructed surface's ability to reflect solar heat, as shown by a small temperature rise. It is defined so that a standard black surface (reflectance 0.05, emittance 0.90) is 0 and a standard white surface (reflectance 0.80, emittance 0.90) is 100.
THERMAL MASS WALLAbove grade, exterior building walls that are made of concrete block, concrete, insulated concrete form, masonry cavity, brick, earth, adobe, compressed earth block, rammed earth, and solid timber or logs. The insulation must be at least 50% on the exterior or integral to the wall and the wall must exhibit a weight greater than 15 pounds per square foot.

A wind energy system may include up to two devices.
WOOD-FIRED BOILERAn alternative energy facility designed to burn wood or other organic biomass fuels, which transfers heated air or liquid through a piping or ventilation system to a principal use. All such systems are generally contained within an accessory structure that is not intended for habitation by humans or animals. An outdoor wood-fired boiler may also be known as outdoor wood-fired furnaces, outdoor wood-burning appliances, outdoor hydraulic heaters, and/or hot water stoves.
