  1. Planning Guidelines Land Use: The activities that take place within a given area of space. LIA : Landscape Impact Assessment. Megawatt & Kilowatts: Used as a measurement of electrical generating capacity. A megawatt (MW) is equal to 1,000 kilowatts (kW) or 1,000,000 watts (W). Mitigation: Measures designed to avoid, reduce, remedy or compensate for adverse environmental effects that are identified. Monitoring: Repetitive and continued observation, measurement and evaluation of environmental data to follow changes over a period of time, to assess the efficiency of control measures. Natura 2000 Site: Designated European Site. In combination Special Areas of Conservation and Special Protection Areas will constitute Natura 2000 network of protected sites for habitats and species across the EU. Natural heritage: Refers to habitats and species of flora and fauna. NBP: National Biodiversity Plan (2002), prepared in response to Article 6 of the Convention on Biological Diversity. Noise: Any sound that has the potential to cause disturbance, discomfort or psychological stress to a subject exposed to it. Described as “unwanted sound”. Noise Sensitive Location: In the case of wind energy development, this includes any occupied dwelling house, hostel, health building or place of worship and may include areas of particular scenic quality or special recreational amenity importance. Photomontage: Image whereby an impression of a potential development is superimposed upon an actual photograph. RMP: Record of Monuments and Places, the county maps showing the archaeological sites and accompanying manuals. 105
  2. RPS: Record of Protected Structures, a record of protected structures in the functional area of the Planning Authority and contains an identifying number and address for each protected structure and one or more maps which identifies the location of each protected structure. SAC: Special Area of Conservation under Habitats Directive (92/43/EEC), designated for rare, vulnerable and endangered habitats and species (e.g. plants, mammals and fish), listed in Annexes I and II. Scoping: Process of identifying the significant issues that should be addressed by a particular Environmental Impact Assessment. Sensitivity: Potential for significant change to any element in the environment that is subject to impacts. Shadow Flicker – Term used to describe the short-lived effect of shadows cast by rotating blades of wind turbines when the sun passes behind them, which occurs under certain combinations of geographical positions and time of day. SPA: Special Protection Area under Birds Directive (79/409/EEC), designated for bird species listed in Annex I of the Directive, in particular internationally important concentrations of migratory and wetland birds. Designation is focused on habitats of these species. Substation: Connects the local electricity network to the electrical system of the wind energy project through a series of automatic safety switches. Threshold: Magnitude of a project, which if exceeded, will trigger the requirement for an Environmental Impact Assessment. TPER: Total Primary Energy Requirement. VAC: Visual Absorption Capacity. This attempts to measure the inherent ability of a landscape to absorb development without 106lanning Guidelines
  3. Planning Guidelines loss of visual integrity, i.e., still maintain its visual character. The more complex the landscape, the higher the VAC. VPs: View points. VRPs: Viewshed Reference Points. Those locations from where visibility of the proposed wind energy development might be provided. Wire frame/wireline diagram: Computer generated diagrams that illustrate how development will appear upon landforms from identified viewpoints. A useful tool to illustrate visual impact, especially when used in combination with photographs from the same view. ZVI: Zone of Visual Influence: Provides a visual representation, usually presented as a map with markings or colourings, of the area over which a site and/or a proposed development may be visible. ZTV: Zone of Theoretical Visibility. The maps produced are theoretical because they estimate exposure of proposed development based upon landform data only, and take no account of intermittent screening by vegetation or structures. ZTV maps estimate visibility of the proposed development in the surrounding landscape and not its “visual influence”. 107
