Description: Das Projekt "Windenergie fuer die bebaute Umgebung" wird vom Umweltbundesamt gefördert und von Universität Stuttgart, Institut für Baukonstruktion und Entwerfen Lehrstuhl 1 durchgeführt. General Information: Acceptability of wind turbines has met much opposition in recent years, partially because they are frequently seen as sharply contrasting intrusions into the natural landscape, since no other man-made structures are normally found around them. This proposal will address the acceptability issues by developing and integrating turbines into built environment in order to bring power generation closer to usage and also to contribute to the 'zero energy building' goal. It is also recognised that most built-up areas in Europe have low-to-moderate wind speed regime, partially because of the effect that increased surface roughness has on an atmospheric boundary layer profile. For these reasons wind applications in built-up areas have to fulfils several specific requirements which will be addressed in the proposal. The key objectives are: 1. to develop wind enhancement and integration techniques for low to moderate wind speed areas (2.5 to 5 m/s annual average) in order to increase the 'qualifying land mass area' for wind utilization in the AEU by improving the annual energy yield per installation. Particular attention would be given to wind concentration techniques using optimised building forms and purpose-made solid structures to create the 'accelerated wind environment'. 2. to develop turbine specification to cater for the above applications. Additionally these turbines would have to be closely controllable, with low noise emissions and be suitable for sensitive environmental integration in or around inhabited areas. All important environmental implications would be investigated. 3. to prove/demonstrate the above techniques on a scaled model in the field. 4. to assess and improve prospects for social, aesthetical and planning acceptability of such wind energy applications. There are specific requirements that wind turbines for inhabited areas must satisfy in response to specific problems related to this type of application. They are going to be specifically addressed in this project. 1. Physical Safety. Prevention of injury to humans, birds, etc. will be an important aspect of urban application. Safety could be compromised due to reasons like blade rotation, high winds and possible blade shedding due to material fatigue. 2. Noise. The noise levels at neighbouring properties would not normally be allowed to exceed the level of background noise or 45 dB(A), whichever is higher. For this reason, quiet turbines are needed. The mechanical gear would have to be placed in an acoustic enclosure. Special types of control may have to be implemented in order to control the rotational speed in accordance with the background noise level at reference points in the surroundings. 3. Vibration and Resonance. Special structural provisions at the interface between the turbines and surrounding structures may be needed to avoid these effects...
