On Roof Geometry for Urban Wind Energy Exploitation in High-Rise Buildings

摘要: The European program HORIZON2020 aims to have 20% of electricity produced by renewable sources. building sector represents 40% the Union energy consumption. Reducing consumption in buildings is therefore a priority for efficiency. present investigation explores most adequate roof shapes compatible with placement different types small wind generators on high-rise urban exploitation. flow around traditional state-of-the-art considered. In addition, influence edge analyzed. These geometries are investigated, both qualitatively and quantitatively, turbulence intensity threshold horizontal axis turbines exploitation identified, studying vertical profiles velocity, turbulent kinetic intensity. Curved interesting from point view, leading highest speed-up lowest
