PART 13
ENVIRONMENTAL IMPROVEMENTS AND ENERGY CONSERVATION REQUIREMENTS
§ 27-1301 Intent.
[Ord. 6-4-84, 6/4/1984, § 16.01]
The environmental improvements and energy conservation requirements are designed to recognize the need for conservation of energy and natural resources and to facilitate the utilization of renewable resources. Environmental improvements are intended to moderate the effects of solar radiation, conserve energy, improve air quality, reduce glare and noise, and control erosion, largely through the planting of trees, shrubs, and other vegetative cover. Energy conservation requirements are designed to allow the installation of renewable energy devices and provide the opportunity for individuals to reduce energy dependence by encouraging the productive use of solar and wind energy components.
§ 27-1302 Definitions.
[Ord. 6-4-84, 6/4/1984, § 16.02]
The following terms are specifically defined for use within this Part:
ACTIVE SOLAR ENERGY SYSTEM
A solar energy system that requires external mechanical power to move collected heat.
DENSE SCREEN PLANTING
A landscaped barrier consisting of predominantly (80% or more) coniferous trees and shrubs, hedges, earth mounding, walls, or a combination thereof established at a minimum height of six feet. Such environmental buffer shall provide a solid visual, noise and pollutant barrier between potentially incompatible uses. Dense screen plantings shall be at least five feet in width with irregularly spaced double or triple rows of plants and shrubs to obtain a dense, solid mass.
ENERGY STORAGE FACILITY
Equipment consisting of containers, heat exchangers, piping, and other transfer mechanisms (including fluids, gases or solids), controls, and related structural support for transporting and storing collected energy (from solar energy systems), including structural elements designed for use in passive solar energy systems.
INTERIOR ISLAND PLANTING
A durable landscaped planting area located within a vehicular use area or parking lot. Design and location shall provide shade and visual separation of parking and pedestrian areas, improve air quality, and control stormwater runoff from large paved areas. An island or strip shall be a minimum of 50 square feet in area, at least five feet in width and contain at least one shade tree, per 40 lineal feet of island or fraction thereof. Islands of 40 feet or less in length shall contain at least one shade tree. The remaining area within the island or strip shall be appropriately landscaped with grass, mulch, stones, plants, or other materials not exceeding three feet in height.
PASSIVE SOLAR ENERGY SYSTEM
A solar energy system that uses natural and architectural components to collect and store energy without using any external mechanical power.
PERIMETER PLANTING
A landscaped planting consisting of trees and shrubs established at less than three feet or greater than six feet in height, so as not to interfere with any clear sight triangle. Such planting shall separate streets and vehicular use areas from parking lots, buildings, and other interior improvements. Perimeter plantings shall consist of individual trees or shrubs spaced a maximum of 50 feet apart to form a linear vegetative border, with grass or ground cover continuously thereunder.
SCREEN PLANTING
A landscaped planting consisting of a mixture of coniferous trees or shrubs, shade trees, ornamental trees or shrubs, earth mounding, hedges or combination thereof established at a minimum height of six feet. Such planting shall separate and protect uses from noise, odor and dust, as well as moderating the effects of winter winds and summer heat. Screen plantings shall be at least three feet in width with regularly spaced trees and shrubs to obtain a pervious, moderately dense planting.
SOLAR COLLECTOR
A free standing or fixed device, or combination of devices, structures, or part of a device or structure that transforms direct solar energy into thermal, chemical or electrical energy that contributes significantly to a structure's energy supply.
SOLAR ENERGY
Radiant energy (direct, diffuse and reflected) received from the sun.
SOLAR ENERGY SYSTEM
A complete design or assembly consisting of a solar energy collector, an energy storage facility (where used), and components for the distribution of transformed energy.
SOLAR FARM
A solar energy system or components thereof installed on land for the sale and distribution of solar energy for the purpose of commercial gain by the landowner, tenant, or lessee of the subject parcel.
[Added by Ord. No. 5-2022, 3/21/2022]
SKYSPACE
The open space between a solar or wind collector and the sun or prevailing wind which must be free of obstructions that may shade or impede the collector to an extent that would reduce its cost-effective operation.
WIND ENERGY CONVERSION SYSTEM
A device which converts wind energy to mechanical or electrical supply; commonly referred to as windmills.
WIND ROTOR
The blades, plus hub to which the blades are attached, that are used to capture wind for the purpose of energy conversion. The wind rotor is used on a pole or tower along with other generating and electrical storage equipment and forms a wind energy conversion system.
